Andúril (MobMuPlat app): fwd/bwd looper + 14 effects + elven cloak (control parameters via env~ and pitch as you play)

UPDATED VERSION (corrected MobMuPlat system crash problem):
anduril.zip

This has been long in coming and I am very glad to finally release it (even tho my handheld hardware is not up to the job of running the elven cloak feature).

First a demo video and some screenshots, , and then the instructions.

DEMO VIDEO

SCREENSHOTS

Intention(s):

The app is designed to give (specifically a guitarist) tho really any input (even prerecorded as is the case in the demo (from: "Laura DeNardis Performing Pachabels Canon" from https://archive.org/details/LauraDenardisPerformingPachabelsCanon, specifically the wave file at: https://archive.org/download/LauraDenardisPerformingPachabelsCanon/PachabelsCanon.wav, Attribution-Noncommercial-Share Alike 3.0) FULL Control over the "voice" of their output-sound.

It includes:

a 5-band EQ (on page 2 of the app) (upfront that is applied to all incoming sounds);

a looper: with record, forward, backward, speed, and bypass controls (that runs via a throw along with the effects channel)

14 effects each with 3 controllable parameters (via the xy-slider+centered knob) including: chorus, distortion, delay, reverb, flanger, tremolo, vibrato, vcf, pitchshifter, pitchdelay, 12string, stepvibrato, pushdelay (delayfb driven by magnitude of the env~), and stagdelay (2 out-of-sync delay lines which can be driven in and out of phase by the sum of their delwrite+vd's so what goes in first may come out last)

elven_cloak: which drives the 3 parameter controls via the peak bands amplitude and proximity to a set pitch (midi note) and whose window can be broadened or shrunk and shifted within that window, i.e. the three effect parameters are changed automatically according to what and how you play

and

a tester synth: that randomly sends midi pitches between 20-108, velocities between 20-127, and durations between 250-500ms.

CONTROLS (from top-left to bottom-right):

PAGE 1:

Effect: effects menu where the you choose an effect;
>>>,<<<: page navigation buttons;
IN,OUT: gains (IN is the preamp on the EQ5, and OUT is applied to total output);
REC,FWD,BWD,speed,normspd: the looper toggles and on speed, higher is faster and mid normal and normspd resets to mid;
xy-slider+centered knob: the 3 parameter controls + their labels (the bottom is x, top y and above the knob for the third one), the name of the selected effect and its parameters load each time you choose from the Effects menu, bottom left is lowest, top-right highest;
ByLp,ByEff: bypasses for the looper and effects "channel" (the outputs are summed);
EC-on: elven cloak toggle (default=off);

PAGE 2:

the EQ5 controls;
synthtest: off|on, default is off;

PAGE 3: elven cloak controls

reset: sets shift, metro, mid, and radius to 0, 500(ms),64,100% respectively (i.e. the entire midispectrum, 0-127) respectively;
mini-xyz, test: if test is on, you see a miniature representation of the xyz controls on the first page, so you can calibrate the cloak to your desired values;
shift: throws the center of the range to either the left or right(+/-1);
metro: how frequently in milliseconds to take env~ readings;
mid: the center in midipitch, i.e. 0-127, of the "watched" bands
radius(%): the width of the total bands to watch as a percentage of whichever is lower 1-mid or mid

END CONTROLS

Basic Logic:

There are 4 modes according to the bypass state of the looper and effects.
A throw catch and gain/sum/divide is applied accordingly.

End:

As I mentioned at the first, my handheld(s) are not good enough to let me use this but it runs great on my laptop.

So...

I would love to hear if this Does or Does Not work for others and even better any output others might make using it. I am enormously curious to hear what is "possible" with it.

Presets have not (yet been included as I see it, esp. with the cloak as a tool to be used for improv and less set work. Tho I think it will work nicely for that too if you just turn the cloak off.

hmmm, hmmm,...

I think that's about it.

Let me know if you need any help, suggestions, ideas, explanations, etc. etc. etc. regarding the tool. I would be more than happy to share what I learned.

Peace, Love, and Ever-Lasting Music.

Sincerely,
Scott

p.s. please let me know if I did not handle the "attribution" part of "Laura DeNardis Performing Pachabels Canon" License correctly and I will correct it immediately.

Ciao, for now. Happy PD-ing!

Audio Ideas (AI) Collection (placeholder) currently only links

per @LiamG 's kind suggestion I have begun the process of consolidating my abs and patches, etc. into a single location/zip file or for possible upload to github.

Just to get the ball/me rolling and scope the work I got the links for my shares into a single location to later be consolidated into the single AI Collection.

For now at least, please, bare with me (and the links below) as ideas I am more passionate about currently are demanding my attention. (Which funnily enough will probably also be included in the set, where ever they are shared.)

Thanks, for your patience and all you do for the Pure Data Family.

Sincerely,
Scott

Background:

Last week I made the (what I now know as "life-altering") commitment to buy (and did) my first usb+midi keyboard controller, a Samson Graphite M25. I have since set up my shop (since given my tools+configuration I could not use the Graphite Preset Editor and because everything works better if you get pd involved :---)) to run the kb into pd then into amsynth via jack, using pd as the midi interface: kb>pd>amsynth>out.

In the process, one thing I did was upgrade the 32 "pre", preset button knobs, to 120, using the ideas included in this abstraction: convert the 4 pads and their binary-ness into decimals, so I can then tell pd to make the knobs, 8x15, instead of 8x4 (the default PRE pad count), see below for clarification...

Requirement(s): Linux and shell external (though I am pretty sure a version using the "until" object is do-able, I did not find one and know the shell waaayyy better than until or even metro.

Synopsis: by pushing on various combinations of pads (could actually be any set of cc(?)'s) the resulting binary number is turned into a decimal which can then be used to re-route or set a different control, ex. PROG.

(from the _help file comments):

Purpose: convert binary values to decimals in order to simplify and expand the rerouting from one control to another, ex. from POLTYTOUCH to PROG.

The left inlet takes a routing/control value,;
ex. note/polytouch control, etc.;
the middle inlet takes the value from that control;
and the right inlet takes a bang to trigger/get/output;
the decimal equivalent.

4pad/trigger to 16 pad/trigger binary-to-decimal converter;
the patch converts the pressing of multiple pads;
to a binary number then to a decimal so that;
for ex. a 4 pad control can send signals from 1-15.

the "shell" external is required;
and the shell script, named:bin2dec_pd, is;
also required. It includes only a single line, echo "$((2#$1))".

FYI: in the polytouch instance, the control is looking for;
127 as a trigger value, so the pads must be pushed Completely down.

I DO believe a metro or until version;
of this is also possible but the shell was more expedient.;

abs_4to16pads_bin_conv_sv.zip

I've been working on my first major patch for the past few months. It's a synthesizer based heavily on the tutorial on flossmanuals.net. After finally creating all of the features I wanted I started to modify the patch to make the synthesizer polyphonic. The catch is that I want to control the patch using the Mad Catz Mustang midi guitar controller. This controller works perfectly fine with the polyphonic synth in the PD help browser as well as with other polyphonic synth patches I've found online, so I do not think the controller has any problem interacting with the [poly] object.. The problem is that when I use it with my patch, some notes fail to turn off. It seems to happen most often when I quickly slur from one note to another. I did not have this issue when using the monophonic version of my patch. The amplifier subpatch is definitely receiving noteoff messages, but for some reason, they do not cause the envelope to close.

I think part of the problem has to do with the way the controller sends messages. I use the controller in 'tap mode,' meaning a noteon is sent whenever a fret button is pressed and noteoffs are sent when fret buttons are released. However noteoffs are also sent whenever any fret button is pressed in order to turn off the "open string" (A note can be played without pressing a fret button by striking the string sensors, and the only way to turn it off is by playing a fretted note). This occurs whether or not the open string is playing and I think this may be messing with [poly]'s voice allocation. I'm tempted to just say that the controller can't be worked around, but since I know it works for other patches I'm going crazy trying to fix my patch.

I understand it would be hard to duplicate this behavior without having the controller, but as I said before it works like a dream with other patches. I have tried to imitate the polyphony of these patches as best as I can. I've tried disconnecting and reconnecting objects in every order imaginable and I've tried delaying on and off messages in case they were somehow arriving to the amplifier envelope out of order.

Attached is a simplified version of my polyph[full poly help.pd] onic patch. I'd really appreciate it if anyone could give it a quick look over just in case there's anything really obvious that I'm just missing.

Thanks so much and have a great day.

full poly help.pd

EDIT: Please ignore the errors about missing {receive~}s or {catch~}es. The {send~}s and {throw~}s are for some of the features that I removed from this version of the patch for simplicity's sake but I did not remove the {send~}s and {throw~}s.

I had a similar problem packing ctlin outlets for further routing.

The control value bangs after the control number. The control number is used to route the control value to its place, so whoever got the control value, it was always one bang delayed. This was specially irritating because my controls would never go to zero (I made a simple drawbar organ).

I worked around this problem by inserting an extra value to the left of the pack, thus creating a dummy hot inlet. I fed the dummy hot inlet with the last banging signal (the control value), and then removed it with an unpack. Then I packed it again, this time with no dummy value.

I am considering getting a Gakken SX150 ( http://www.makershed.com/ProductDetails.asp?ProductCode=MKGK8 ), and want to make it into a MIDI controller. However, I do not have much money and would not like to spend money on hardware mods. I came across this program ( http://cmpercussion.blogspot.com/2008/08/theremin-to-midi-control-program-in-pd.html ) for use with Theremins, when I was researching Theremins, and was wondering if it could be used with a Gakken SX150. Would I need to keep it on a clean tone? If I needed to modify this program, how extensively and how much knowledge of pd would I need? And finally, would it still work if I decided to add a ribbon controller to the Gakken, like this http://www.coagula.org/content/pages/gakken-sx-150-hacking-controller-tutorial ?

Hmmmm...I built one like this once...I think.

I don't recall exactly what I did but I think this would work (better):

First things first, decide what controls it. If it's MIDI you're looking at 0-127 control values, better off with Audio control. You can make a 128 point table that uses the curve you like, then read it from [tabread4~] with a MIDI CC or a [line~] for (much) higher resolution.

Anyhoo, it sounds like you'll want to take advantage of [moses] to separate the the control values into different ranges. Here's a thought:

0-24: controls LPF
24-48: controls LPF & BPF & and a crossfade curve between them
48-72: controls BPF
72-96: controls BPF & HPF and a crossfade curve between them
96-127: controls HPF

And now someone will say "but the phase distortion..." Yeah, I'm not phased.

When we say morphing there are much more complex ways of accomplishing this effect than crossfading - but crossfading is simple.

For visualizing it - well, you know what it does so it's an unnecessary burden on your CPU, but if you don't care about latency you can explore data structures - it'd be difficult to construct. Other alternatives are silly, like using noise and an FFT plot - but you'd be able to do that by hacking apart the resynthesis sample I think, again only if you are using it for production.

Please share, I could use a well thought out filter of this type - it's common in the old Traktor, right?

Xth Sense &#8211; biophysical generation and control of music

@NK
Elsenstr. 52/
2.Hinterhaus Etage 2
12059 Berlin Neukölln

FULL PROGRAM: http://www.nkprojekt.de/xth-sense-%E2%80%93-biophysical-generation-and-control-of-music/

~ What

The workshop offers an hands-on experience and both theoretical and practical training in gestural control of music and bodily musical performance, deploying the brand-new biosensing technology Xth Sense.

Developed by the workshop teacher Marco Donnarumma within a research project at The University of Edinburgh, Xth Sense is a framework for the application of muscle sounds to the biophysical generation and control of music. It consists of a low cost, DIY biosensing wearable device and an Open Source based software for capture, analysis and audio processing of biological sounds of the body (Pure Data-based).
Muscle sounds are captured in real time and used both as sonic source material and control values for sound effects, enabling the performer to control music simply with his body and kinetic energy. Forget your mice, MIDI controllers, you will not even need to look at your laptop anymore.

The Xth Sense biosensor was designed to be easily implemented by anyone, no previous experience in
electronics is required.

The applications of the Xth Sense technology are manifold: from complex gestural control of samples and audio synthesis, through biophysical generation of music and sounds, to kinetic control of real time digital processing of traditional musical instruments, and more.

~ How

Firstly, participants will be introduced to the Xth Sense Technology by its author and led through the assembling of their own biosensing wearable hardware using the materials provided.
Next, they will become proficient with the Xth Sense software framework: all the features of the framework will be unleashed through practical exercises.

Theoretical background on the state of art of gestural control of music and new musical instruments will be developed by means of an audiovisual review and participatory critical analysis of relevant projects selected by the instructor.

Eventually, participants will combine hardware and software to implement a solo or group performance to be presented during the closing event. At the end of the workshop, participants will be free to keep the Xth Sense biosensors they built and the related software for their own use.

~ Perspective participants

The workshop is open to anyone passionate about sound and music. Musical background and education does not matter as long as you are ready to challenge your usual perspective on musical performance. Composers, producers, sound designers, musicians, field recordists are all welcome to join our team for an innovative and highly creative experience. No previous experience in electronics or programming is required, however participants should be familiar with digital music creation.

Participation is limited to 10 candidates.
Preregistration is required and can be done by sending an email to info@nkprojekt.de

Requirements and further info
Participants need to provide their own headphones, soundcards and laptops with Pd-extended already installed.

Musicians interested in augmenting their favourite musical instrument by means of body gestures are encouraged to bring their instrument along. More information about the Xth Sense and a video of a live performance can be viewed on-line at

First my story: (you can skip down to END OF STORY if you want)

Ever since I saw Mike Relm go to town with a DVDJ, I've wanted a system where I could scratch and cue video. However, I haven't wanted to spend the $2500 for a DVDJ. As I was researching, I found a number of different systems. I am not a DJ by trade, so to get a system like Traktor or Serrato with their video modules plus turntables plus hardware plus a DJ mixer, soon everything gets really expensive. But in looking around, I found the Ms.Pinky system and after a little bit, I found a USB turntable on Woot for $60. So I bought it. It was marketed as a DJ turntable, but I knew that it wasn't really serious since it had a belt drive, but it came with a slip-pad and the USB connection meant that I wouldn't need a preamp. And so I spend the $100 on the Ms.Pinky vinyl plus software license (now only $80). This worked decently, but I had a lot of trouble really getting it totally on point. The relative mode worked well, but sometimes would skip if I scratched too vigorously. The absolute mode I couldn't get to work at all. After reading a little more, I came to the conclusion that my signal from vinyl to computer just wasn't strong enough, so I would need maybe a new needle or maybe a different turntable and I didn't really want to spend the money experimenting. I think that the Ms. Pinky system is probably a very good system with the right equipment, but I don't do this professionally, so I don't want to spend the loot on a system.

Earlier, before I bought Ms.Pinky (about two years ago), I had also looked around for a cheap MIDI USB DJ controller and not found one. Well, about a month ago, I saw the ION Discover DJ controller was on sale at Bed, Bath & Beyond for $50. They sold out before I could get one, but Vann's was selling it for $70, so I decided that that was good enough and bought one. I had planned to try to use it with Ms. Pinky since you can hook up MIDI controllers to it. But it turns out that you can hook up MIDI controllers to every control except the turntable, so that was a no go. If I had Max/MSP/Jitter, I could have changed that, but that's also way expensive. So, how should I scratch? My controller came with DJ'ing software and there's also some freeware, like Mixxx, but none of this has video support. So I look around and find Pure Data and GEM.

And I see lots of questions about scratching, how to do it. And there are even some tutorials and small patches out there, but as I look at them, none of them are quite what I'm looking for. The YouTube tutorial is really problematic because it's no good at all for scratching a song. It can create a scratching sound for a small sample, but it's taking the turntable's speed and using that as the position in the sample. If you did that with a longer song, it wouldn't even sound like a scratch. And then there are some which do work right, but none of them keep track of where you are in the playback. So, whenever you start scratching, you're starting from the beginning of the song or the middle.

So, I looked at all this and I said, "Hey, I can do this. I've got my spring break coming up. Looking at how easy PD looks and how much other good (if imperfect) work other people have done, I bet that I could build a good system for audio and video scratching within a week." And, I have.

END OF STORY

So that's what I'm presenting to you, my free audio and video scratching system in Pure Data (Pd-extended, really). I use the name DJ Lease Def, so it's the Lease Def DJ system. It's not quite perfect because it loads its samples into tables using soundfiler which means that it has a huge delay when you load a new file during which the whole thing goes silent. I am unhappy about this, but unsure how to fix it. Otherwise, it's pretty nifty. Anyway, rather than be one big patch, it relies on a system of patches which work with each other. Each of the different parts will come in several versions and you can choose which one you want to use and load up the different parts and they should work together correctly. Right now, for most of the parts there's only one version, but I'll be adding others later.

There's a more detailed instruction manual in the .zip file, but the summary is that you load:

the engine (only one version right now): loads the files, does the actual signal processing and playback

one control patch (three versions to choose from currently, two GUI versions and a MIDI version specific to the Ion Discover DJ): is used to do most of the controlling of the engine other than loading files such as scratching, fading, adjusting volume, etc.

zero or one cueing patch (one version, optional): manages the controls for jumping around to different points in songs

zero or one net patch (one version: video playback): does some sort of add-on. Will probably most commonly be used for video. The net patches have to run in a separate instance of Pd-extended and they listen for signals from the engine via local UDP packets. This is set-up this way because when the audio and video tried to run in the same instance, I would get periodic little pops, clicks, and other unsmoothnesses. The audio part renders 1000 times per second for maximum fidelity, but the video part only renders like 30 or 60 times per second. Pure Data is not quite smooth enough to handle this in a clever real-time multithreading manner to ensure that they both always get their time slices. But you put them in separate processes, it all works fine.

So, anyway, it's real scratching beginning exactly where you were in playing the song and when you stop scratching it picks up just where you left off, you can set and jump to cue points, and it does video which will follow right along with both the scratching and cuing. So I'm pretty proud of it. The downsides are that you have to separate the audio and video files, that the audio has to be uncompressed aiff or wav (and that loading a new file pauses everything for like 10 seconds), that for really smooth video when you're scratching or playing backwards you have to encode it with a codec with no inter-frame encoding such as MJPEG, which results in bigger video files (but the playback scratches perfectly as a result).

So anyway, check it out, let me know what you think. If you have any questions or feedback please share. If anyone wants to build control patches for other MIDI hardware, please do and share them with me. I'd be glad to include them in the download. The different patches communicate using send and receive with a standard set of symbols. I've included documentation about what the expected symbols and values are. Also, if anyone wants me to write patches for some piece of hardware that you have, if you can give me one, I'll be glad to do it.
