For each program that is using the ASIO drivers, an ASIO control panel will pop up in the system tray (you might need to adjust your system tray preferences). Each panel controls an instance of the ASIO drivers for that program. You can open that panel and set the inputs and outputs you want to use for that instance.

I said in the above post that ASIO can connect to one program at a time....but that isn't the full explanation. Each ASIO instance can connect 1 program to the same hardware inputs and outputs at a time.

So if you had a soundcard that had 4 outputs, you can setup 2 programs to use the ASIO drivers, one instance goes to output1 and output2, and the other instance can go to output3 and output4.

Getting your sound program running through ASIO (that's by default connected to all inputs and outputs) and getting sound from the browser (Firefox? Chrome? IE?)
is tricky. The browser doesn't use ASIO, it's using the default windows sound driver to access the soundcard. Try loading the browser first then load PD with ASIO or vica versa.

I've only been able to get a consistent working setup by having multiple (2 or more) soundcards. Windows controls one (browser sound, programs that don't use ASIO) and ASIO drivers control the other (PD, tracktor, cubase, FLstudio, etc). Route the sound output from both cards into an external mixer, and the mixer controls the main speakers (or monitors)

Thanks Maelstorm.

glitchpop. yeah. I'm also doing some control from the gem window with the keyboard and mouse. I don't have everything controllable from the gem window yet but I'm working on it. Also need to get my keypresses and mouse movement recordable so I can play it back and overdub more control.

As is it's running great on Vista with no glitching. I have the hardware accelerated opengl drivers and decent ASIO drivers. With Puredyne I think my video card driver overwrote my ALSA driver so I need to find my original ALSA driver hopefully without reinstalling PureDyne. Crazy I don't know what kind of sound card is in this machine.

Hey

Once again I'm back on vista. My brief journey to puredyne goes something like this.

from puredyne
partitioned new hard drive with 4 partitions 1-swap , 2 ext4 200Gib, 1 NTFS 200GB . Copied Vista to NTFS partition with gparted(started to do this with dd but with new Gibabits stuff I was skeered but hey a platter is a platter and a cluster is a cluster right). Actually there was a 5th partition in there which was the vista restoration partition but I eventually deleted it for obvious reasons.

Removed old drive ,
took machine to ethernet connection with internet,
booted to vista ,
installed Norton virus scanner - only 1 virus, 2 tracking cookies, and one gain trickler after over a year with no virus scanner, Thats pretty good and shows you can be selective about what you download and where you visit on the web and not get any viruses.

Was trying to get windows movie maker to work with mov codec which it doesnt.
Installed auto updates for the first and only time. this took about 3 hours and still needed to install service pack 1, 2. Aborted trying to update win movie maker

****Problem 1***** MS movie maker does not work with GEM mov video output codec.

Installed latest Nvidia drivers for vista.
Woohooo OpenGl hardware acceleration GEM works so much better in vista now.

*****Problem 2********ASIO for all does not allow 2 applications to run with audio and midi at the same time. If I wanted to run Widi and play my guitar so puredata can receive midi input from guitar ASIO will not allow it but ASIO for all is the only way I can get latency down so this would be feasible.

Got frustrated.

Installed fresh copy of puredyne onto 2nd ext4 partition.
ran puredata audio latency good with fresh install. gem video bad.

used synaptics to install nvidia drivers. v185 I think.
ran GEm error no opengl config.

downloaded gdeb , flash player, google chrome, nvidia drivers from nvidia site.
installed gdeb from terminal, flash and chrome from gdeb.
rebooted to log in as root and iunstalled nvidia drivers.

woohoo hardware acceleration for opengl

******problem 3************
gem works great but audio glitches with puredata window visible.
when only gem window is visible i can unaudioglitchily move the mouse around to control same parameters that would normaly be controled with sliders in pd window.

Seems like before i upgraded nvidia video drivers hw:do o whatever it is, was listed in JackD as realtek HD Audio, now it is listed as NVIDIA HD Audio.

So Gem works great but not when Pd window is open and I think my audio drivers were replaced with Nvidia.

I would really like to get back to my patch and stop wasting time on these operating systems and hardware configurations I thought in the last 15 years all this hardware acelleration and autodetection would be figured out but no all we got is rc.0, rc.01, rc.02, rc, etc...... instead of just rc.d.

Ok I'm getting an error when I exit puredyne that says pid file not found is jackd running. anyone know what that means?

Also does anyone have a keymap for gem keyboard for linux, windows and mac so I don't have to record them.

Any suggestions about what to do about my ASIO problems in windows?
Any suggestions about my audio driver in Linux?
Any suggestions about my GEM mov video / windows incompatibilities?

I can import the mov video and audio to SF Acid 3.0 and output a 2Gb avi then import it into windows movie maker but this is crazy to do for a 7 minute 12fps 320x240 video.

Ahhhhhhhhh!
Any suggestions are welcome!

PS I believe someone could rewrite puredata's audio and video interface in assembly language to control their hardware before figuring out how to get these operating systems to do it.

I got a response from the creator of Gridflow on the mailing list, which I'll reprint here in case it can help people

I've made a simple video mixer in Gridflow (9.13) and I want to send the output to an external projector. I've set up my computer so that I can drag windows to the second screen, but when I attempt to go full screen using [#out sdl] and then pressing Esc it goes fullscreen on both screens.

Sounds like the kind of problem that can't be solved in GridFlow. It's a SDL issue.

If I use an [#out window] object, which I believe is an x11 window, there's no way (that I can find) to go full screen, so I'm stuck at with an 800x600 window on a 1366x768 screen. I did attempt to use a [#scale_to (768 1366)] object to emulate being full screen but the scaling causes a massive drop in framerate.

Changing the screen resolution is a sure way to avoid even having to scale.

[#scale_to] is a simple abstraction not meant to be fast or fancy. It would be a good thing to make a much better software scaler for GridFlow (interpolating and faster), but it wouldn't be as fast as a hardware-accelerated scaler, or simply changing the screen resolution.

Changing screen resolution also gives you the best image quality when using a CRT, whereas on a LCD it just means you're getting the LCD monitor to do the scaling for you.

Can anyone suggest how to go fullscreen on only one screen, how to go fullscreen using an x11 window or some other way to do this?

There is the "border" method for removing the border, the "move" method to put a window wherever you want (compute window coordinates to match the way the mouse travels from one screen to the other).

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.

Hello brilliant creators of music,
In an attempt to reduce my sound synthesis latency I picked up a new sound card with ASIO drivers. When I got the card I re-configured PD to use the ASIO drivers, and I set my latency down to ~10 ms, and the audio sounded fine. However, when I tested the latency I found out that I get an extra 100 ms delay on top of PD's delay when I use the ASIO drivers. When I take this mystery latency into account, I get better latency when I use the MMIO drivers.

I noticed that PD uses pulseaudio for routing when it uses the ASIO drivers. I know that pulseaudio is supposed to be low latency, but could this be where my magic 100ms delay is coming from? If so, do any of you know how to fix it?

thanks!

Hi all,
I used to have pd working perfectly well with my Fireface 400 (under windows xp). I was using an autobuild dating from 30-04-2010. Previous versions of pure data didn't recognize the asio fireface drivers.
But this evening I decided to update my version of pd to the last stable release. And here is my problem: pd see's the asio fireface drivers, but if I try to select it, no audio works... and in the "media" menu Asio dosen't appeared as ticked...

I would have liked to be able to install my previous version of pd, but I no longer have the exe file, and can't find it on the internet anymore (are old versions of pd kept somewhere?).

I have tried with the official stable 42.5 release, and with several autobuilds, and on 2 different windows machine (xp and 7) and allways get the same trouble.

the mmio drivers are available through pd but the latency is then way to big, and they only allow access to 2 ins and 2 outs... so I raelly need to get the asio driver working again.
I would greatly appreciate any help. thanks,
Ben

To get the MOST of your patch, you need to run it on a computer that isn't focused on providing drivers of everything from EVERY printer/scanner/camera that's ever existed to modems, game controllers and pancake makers. You need a computer that doesn't spend it's idle time checking emails, getting widget updates, making sure all applications are given equal rights, performing maintencance during crucial music production time, you need a computer that isn't busy providing 3D, transparent windows, dynamic shadowing, fancy window graphics and poofs of smoke.

You need to run your pd patch on a stripped down, bare bones operating system. You need a custom setup. And for this, there is great news! Because this possibility exists through open source GNU/Linux, and, it's all free!! Best of all, there is already a 'distribution' (tailor made package) aimed at providing optimum performance for sound/visual media artists that will happily sit along-side Windows and requires NO installation!! Crazy, huh!

Check out Pure:Dyne -> http://puredyne.org/

You'll get way more bang from your computer and definitely decrease your latency. So much so that you'll probably not need a new computer.

Here is some more info:

This is development info of VisualTracker for pd (pre alpha 100404)

What is it:

VisualTracker is sample sequencer – it triggers loaded samples in times defined in time line in editor window. Samples can be played in their default speed / length or can be fitted in tempo. In “fit mode” you can define number of bars to fit in and also multiplication of file. All changes have visual interpretation in sample canvases.

VisualTracker for pd (pre alpha 100404) was developed in Pd version 0.41.4-extended, on Windows XP

How to make it work:

1. Open VisualTracker_(pre_alpha_100404).pd in pd.
2. Editor and Samples window are automatically opened.
3. Preset currentstate.vtp is automatically loaded – this preset is saved before closing the patch.
4. After first run there are 3 empty sample boxes in samples window and 3 corresponding sample canvases in editor window.
5. Load any wav (44100 Hz) by pressing „load“ in selected sample box. No space characters in path or filename are allowed. Loading of these files is aborted and error message appears for several seconds. Name of the successfully loaded sample including full path appears in sample box and also sample canvas in editor window. Size of sample canvas is changed according to the sample length. Try to change global BPM – size of sample canvas is recalculated.
6. Check „fit“ to fit sample in current BPM. Set length of sample in bars and multiplication.
7. Add another sample by creating object [sample] or just copy existing sample box in samples window.
8. Switch to editor window, press CTRL+E to switch to pd edit mode and drag and drop sample canvases to desired position on time line. Sample canvases are automatically snapping to bar columns and rows.
9. Switch back to normal mode by CTRL+E
10. Press PLAY to replay your sample composition. Samples are played only if corresponding sample canvas is placed in track 1-6. If sample canvas is above the tracks sound is muted.
11. Press „save“ in main VisualTracker window to save current preset to a text file. Any name and extension with no spaces is allowed.
12. Before closing VisualTracker press „save state & close“. It saves current state to preset named currentstate.vtp and delete all sample boxes from samples window and all sample canvases from editor window. Now you can turn off and eventually save VisualTracker patch. This is important to avoid double appearance of sample canvases because information about samples and composition is stored independently from pd patch and should not be saved inside patch. If there are still some „orphaned“ sample canvases hanging delete them manually.

Components:

1. Sample window: place for unlimited amount of [sample] abstractions. Once abstraction is created (by copying or creating the object) corresponding sample canvas is created in editor window. [sample] abstraction is sending data to sample canvas (name, color, size, snapping) and receiving back position. Triggering of sample playback is based on position of sample canvas.
2. Editor window: place for sample canvases composition on the top of timeline grid. Sample canvases can be moved by mouse in pd edit mode (CTRL+E). Timeline grid will be extended and improved in next versions.
3. Preset save/load: saves and loads presets to/from a text file using [coll] object. Preset contains global values (number of samples in composition, bpm) and local values for each sample box (filename, position, track, multiplication, number of bars, fit switch, color and two unused values).
4. Sequencer: located in program subpatch. Very simple - functionality will be extended and improved in next versions
5. Other: located in program subpatch. Contains some other patches as colortable, BPM manager, output etc.
