The Harmonizer: Communal Synthesizer via Wifi-LAN and Mobmuplat

The Harmonizer

The Harmonizer is a single or multi-player mini-moog synthesizer played over a shared LAN.

(credits: The original "minimoog" patch is used by permission from Jaime E. Oliver La Rosa at the the New York University, Music Department and NYU Waverly Labs (Spring 2014) and can be found at: http://nyu-waverlylabs.org/wp-content/uploads/2014/01/minimoog.zip)

One or more players can play the instrument with each player contributing to one or more copies of the synthesizer (via the app installed on each handheld) depending on whether they opt to play "player 1" or "player 2".

By default, all users are "player 1" so any changes to their app, ex. changing a parameter, playing a note, etc., goes to all other players playing "player 1".

If a user is "player 2", then their notes, controls, mod-wheel etc. are all still routed to the network, i.e. to all "player 1"'s, but they hear no sound on their own machine.

There are 2 pages in The Harmonizer. (See screenshots below.)

TheHarmonizer.zip

PAGE 1:

PAGE 2:

The first page of the app contains all controls operating on a (more or less) "meta"-level for the player: in the following order (reading top-left to bottom-right):

pl2: if selected (toggled) the user is choosing to play "player 2"
mot(ion): triggers system motion controls of the osc1,2&3 levels (volume) based on the accelerometer inside the smartphone (i.e as you twist and turn the handheld in your hand the 3 oscs' volumes change)
rate: how frequently should the handheld update its accelerometer data
slimit: by how much should the app slow down sending the (continuous) accelerometer data over the network
presets: from 1 to 5 preset "save-slots" to record and reload the Grid 1 and Grid 2 settings that are currently active
S: save the current Grid1 and Grid2 selections to the current "save slot"
L: load the currently selected preset into both Grids
">>": go the the next page (page 2 has the reverse, a "<<" button)
Grid 1: the settings, in 4 banks of 3 parameters per-, which are labeled top-down equating to left-right
Grid 2: the same as Grid 1, but with a different set of parameters

The second page comprises:

the 2-octave keyboard (lower notes on top),
a 9-button octave grid (which can go either up or down 4 octaves),
a quick-preset grid which loads one of the currently saved 5 presets
the "<<" button mentioned above, and
both a mod and pitch-bend wheel (as labeled).

SETUP:

All players install Mobmuplat;

Receive The Harmonizer (in the form of a .zip file either via download or thru email, etc.)

When on your smartphone, click on the zip file, for example, as an attachment in an email.

Both android and iphone will recognize (unless you have previously set a default behavior for .zip files) the zip file and ask if you would like to open it in Mobmuplat. Do so.

When you open Mobmuplat, you will be presented with a list of names, if in android click the 3 dots in the top right of the window and on the settings window , click "Network" Or on an iphone click "Network" just below the name list;

On the Network tab, click "LANDINI".

Switch "LANDINI" from "off" to "on".

(this will allow you to send your control data over your local area network with anyone else who is on that same LAN).

From that window, click "Documents".

You will be presented again, with the previous list of names.

Scroll down to "TheHarmonizer" and click on it.

The app will open to Page 1 as described and shown in the image above.

Enjoy with Or without Friends, Loved, Ones, or just folks who want to know what you mean "is possible" with Pure Data )!

Theories of Thought on the Matter

My opinion is:

While competition could begin over "who controls" the song, in not too great a deal of time, players will see first hand, that it is better (at least in this case) to work together than against one another.

If any form of competition emerges in the game, for instance loading a preset when a another player was working on a tune or musical idea, the Overall playablilty and gratitude-level will wain.

However, on the other hand, if players see the many, many ways one can constructively collaborate I think the rewards will be far more measurable than the costs, for instance, one player plays notes while the other player plays the controls.

p.s. my thinking is:

since you can play solo: it will be fun to create cool presets when alone then throw them into the mix once you start to play together. (Has sort of a card collecting fee ).

Afterward:

This was just too easy Not to do.

It conjoins many aspects of pure data together (I have been working on lately (afterward: i did this app a long time ago but for some reason and am only now thinking to share it) both logistical and procedural into a single whole.

I think it does both quite well, as well as, offer the user an opportunity to consider or perhaps even wonder: What is 'possible'?"

Always share. Life is just too damn short not to.

Love only.

Hi, All.

I'm stumped...

Here's what I have so far (see "TiGR-Resurrected-20160709.zip" below, requires Mobmuplat development environment):

a (19 page) Mobmuplat (MMP) frontend, that I use as the GUI, which I run on my laptop thru the MMP editor (which someone sort of suggested, since my handheld can Not handle the load of the app on its own-Note: I have tried OSC and it does not work as well as this setup);

the first page is the Main Page;

the subsequent 18 pages each have one unique pedal/effect on them with all of its respective controls;

the Main Page has 7 (18 slot) vsliders with each value representing one of the pedals represented by one of the mmp pedal pages;

the Main Page also has a (currently not implemented, but I will probably put it to use once I figure out this issue first) a 7-slot multislider which will be used to change the preset of any pedal in its respective slot;

all pages, including the Main Page, have a preset control abstraction (mine) which saves and loads the page's primary control values;

the Main Page is a "stack" so the guitarist can build a rack of >1 pedal and up to 7 effects (triggering no pedals is just a bypass);

different Main Page slots may be filled with the Same effect, in which case, the most recently applied parameters for a pedal are applied to all of its chosen slots.

GOAL:

While I am playing, be able to smoothly change the "voice", i.e. slot arrangements and pedal parameters (via their presets) of my guitar without taking my hands off the strings/neck.

Work so far:

I used a "Logitect Dual Action (usb game) Controller" and hid library to change the effects (left joystick slots and right joystick pedals). But because I had not setup presets, yet I had it randomizing parameters and while interesting the volume spiking and chances the multiplied gains would be too low was Awful!!!

Needed help:

How would I go about making a (what I am thinking of as a 2-d) stompbox that would let me rearrange the pedals in each slot AND/OR change any given slot's pedal parameters.

I'm not going to have a problem with the logic of it, as I can see clearly how that can be accomplished. But I am unclear how to build or use Or buy a piece of hardware that will allow me to do this.

My first Bad guess, or at least place to start, is it is an array of stompboxes. I can intuitively tell this is way wrong, But I can not, for the life of me, visualize/feel the better or possibly even optimal solution for this.

Little help, please.

So your suggestions, advise, insight, encouragement would all be very, very, very welcome.

Peace and thanks in advance.

Sincerely,
svanya

TiGR-Resurrected-20160709.zip

I returned to this project after a haitus and more learning and while it has become much, much more streamlined and higher headed (:---) it is still having the same issues running inside MobMuPlat: garbled sound.

If you have or can make the time, please, have a look at it, and tell me how I can resolve this problem, as I think it would of benefit to the world-at-large, thru the guitarists in the world, and as there are so few guitar apps, for Android.

It has a simple master patch, largely based on the "Router", into which all of the pedals (16) have been embedded.

And taking whale's (?) advise I added switch~'s to all the pedals so dsp only turns on when they are activated.

The first (MobMuPlat) page is the "rack", TiGR=The (i) Guitar Rack, which each pedal being on a subsequent page (swipe at the top) (note: currently "Presets" and "Record" do not do anything).

The hardware I am using which may be the issue is a Motorola Moto E (2nd Generation) with 4G LTE, Android 5.1, Kernel 3.10.

And I can't tell if it is my hardware's problem or libpd is just not up to the task to handle the load.

Instructions:

You select the pedal from the first page (the sliders, so you can stack multiples of the same pedal)
And
Each page has it's own settings/controls and a bypass.

(Note: more "slots" could be added, if 6 is not enough , by just adding sliders and Routers.)

I thank you so very, very much in advance for any advise you can offer.

Maybe if enough of us chime in we can get this (free) into the hands of all those guitarist who do not have enough supplementary income to spend on a rack.

TiGR_Resurrected.zip

p.s. as to credits, it depends on a lot of other people's work. To name a few, Guitar Extended, hardoff's DYI2 library, tb_compressor, etc., etc.

And to them I say: "Thank You. It is so wonderful to walk on the shoulders of giants who are so kind, generous, and loving. -Peace"

Screenshots:

I'm trying to use touchOSC to control some items in pd_extended using the mrpeach libraries. everything works fine except that when changing page in touchOSC, pure data crashes.

I maybe figured out why since when changing page it sends just "/page" instead of "/page/item value", and since I'm using some cascaded "routeOSC" to address the value to the item I want to change, only the first "routeOSC" sees a value, but then the others receive just a bang.

How can I correct this behaviour? How can I ignore the message when just changing page?

oh yeah, it gets even worse with them, doesn't it.

Hi to all,

I have a patch that convert launchpad midi note to midi CC to an Yamaha RM1X all connected with jack, so i have:

Jack connection :
Launchpad Out ------> Pure Data Midi-in 1 (for the PD patch)
Pure Data midi-Out 1 ----> midisport (for the yamaha)

if i want to use the led of launchpad for visual feedback:

Pure Data midi-Out 2 ----> Launchpad IN

The problem is that the launchpad get and send midi to ch 1, if i send to the lauchpad i send also to the Yamaha, how i can separate this two things ? what object i have to use, if is possible ?

Thanks

Hi to everyboy,

i forgot to post a better guide:

I tested this on linux ubuntu maverick:

before you have to install:

$ sudo apt-get install libusb-1.0-0
$ sudo apt-get install libusb-1.0-0-dev
$ sudo apt-get install libasound2-dev

then extract the sources (from https://github.com/jiyunatori/launchpad, click Downloads, and take the .tar.gz)

cd in the extracted directory compile with:

$ make clean
$ make lpmidi

if you didn't get errors plug the launchpad and run:

$ sudo ./lpmidi

then open jack or alsamidi ports...and you'll find the launchpad midi device.

you can take the lpmidi apps and put where you want, and make a launcher (i put it on the gnomepanel)

I hope this works also for the linux user here, let me know....

All this instruction came from here: http://www.renoise.com/board/index.php?showtopic=26229

thanks

CALL FOR PARTICIPANTS

Blank Pages Sessions use Pure Data or Max/Msp for creating sounds/video by live programming, starting from a blank page, without loading or saving patches. Participants make sounds/music for one hour, after that the session ends.

There will be two Blank Pages Sessions in Munich. To participate, please fill out the registration form, which can be found on the Blank Pages homepage. No hosting possible. The Blank Pages Session in Munich is integrated in a Pure Data Forum, which is part of the Kunstfest Prosume Conduce in Munich, Germany - for details see http://prosumeconduce.info (english text available).

i've also used the launchpad on two little projects.

you mean whatever it's possible to control the launchpad's leds from pd? it's easy: just use the same midi note # as the pad sends to pd. for example, sending midinote 16 /w velocity 15 will turn first pad on the second row to bright red.

this will explain it all (progammes reference at the bottom)
