Jack issues
by Daniel Hawthorn 28 Feb '03

28 Feb '03

Hello all, I've got an M-Audio Quattro set up on my RedHat 8.0 system and I've been having trouble using PD + jack and four channels. When I start jack with the hw driver, the first two channels (in and out) bind fine in PD. However, when I run jack using the q4b driver (4 ins, 4 outs) the outputs bind properly. Although the connections look fine in QJackConnect, with pd's outs connecting to my quattro's two outs in the proper way, I only can get sound out of PD's second output. And furthermore, the sound I get out of the second output is coming out of _all_four_ of my quattro outs. What's going on here? Any ideas? Thanks, -Daniel

Compressor/Gate
by Jordan J 28 Feb '03

28 Feb '03

Has anyone actually programmed a compressor/gate object yet? I've built a simple abstraction. It's pretty crummy though. I'm sure that I'm not using something to my advantage (ie. there's a better way to do it) and I wonder what everyone else thinks. I've attacked the abstraction file. Thanks. -Jordan

pd messages: cut
by David McCallum 28 Feb '03

28 Feb '03

I was playing around with Pd's internal messages and found that the "cut" command only works when the window is visible. So if you issue a cut command to a closed subpatch it won't actually cut anything, but "clear" works just fine. I wasn't sure if this was a feature or a bug... anyone? . . David McCallum .

bendout bug?
by Jim Aikin 28 Feb '03

28 Feb '03

Is there a known bug in bendout? I'm using 0.36 under Windows 98SE. Connecting bendin directly to bendout (not much room for user error there), the receiving synth will bend down, but not up. And that's after it jumps up in pitch the first time I touch the bend lever. A number box attached to the outlet of bendin shows the full expected range of data (0-16383). What seems to be happening is that bendout is adding 8191 to the value before transmitting it. Can anyone confirm this? Does it operate correctly on other systems? --Jim Aikin

free software VST host for windows?
by Josh Steiner 27 Feb '03

27 Feb '03

hey all, i'm trying to help thomas grill debug the *awsome* [vst~] object so that i can work with the fruity loops VSTi ... does anyone know any open source/free software VST hosts? I'd like to test the fruity vsti with another host to see if we can peg down these bugs. i found one called "VST Host" but it does not support the graphical interface of the plugins, which is what i'm testing. thanks. -josh -- ____________________________________________________ independent u.s. drum'n'bass -- http://vitriolix.com

Re: Re: [PD] audio dropouts when loading samples

oops.. i actually use readsf~, which i think is bundled in 0.36? regarding a "threaded version of soundfiler", i believe that's what readsf~ is supposed to be? see: http://www.akustische-kunst.org/puredata/ the question remains though, what if you just have to play back the tail end of a wav file? right now i have to wait for readsf~ to stream in the whole thing ... i suppose there are offset commands and whatnot, but it seems like a real hassle, atm. >awsome, i'm glad to stand corrected on this one ;) i'll have to play >with sfread~ then :) > >eskogen(a)usfamily.net wrote: > >>i've used Pd for interactive performance quite a bit in the past six months >>and this was one of the most irritating problems. my solution was to have >>a series of tables loaded at the start with the first few samples i needed, >>sized to be very large. >> >>i then had an abstraction to sfread~ any sounds i wanted to load later on >>into the arrays. sfread~ is threaded, so it doesn't lock up the GUI and >>audio cause dropouts. this would stream my samples into the array, then >>let me know when the samples was streamed completely. as long as my tables >>were large enough, it was no problem. >> >> >> >> >> >> >> >>>AFAIK there is no way around it for now, if i were you i would just >>>preload all the samples you may want to use each into its own array and >>>then at performance time choose which array you read from. how well >>>this will work out of course depends on how many samples you need. >>> >>> >> >> >> >>>-josh >>> >>> >> >> >> >>>Matthew Nish-Lapidus wrote: >>> >>> >>= >> >> >>>hi, >>> >>>has any one come up with a solution to the problem of audio dropouts when >>>loading wav files into tables? i'm going to be doing some performance soon, >>>and i'd really like to be able to load these samples without getting >>>dropouts. >>> >>> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >>------ http://USFamily.Net/info - Unlimited Internet - From $8.99/mo! ------ >> >> >>_______________________________________________ >>PD-list mailing list >>PD-list(a)iem.kug.ac.at >>http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-list >> >> > > >-- >____________________________________________________ >independent u.s. drum'n'bass -- http://vitriolix.com > > > ------ http://USFamily.Net/info - Unlimited Internet - From $8.99/mo! ------

Force Feedback Joysticks
by Hans-Christoph Steiner 27 Feb '03

27 Feb '03

I was wondering whether anyone here has worked with force feedback joysticks. Specifically any of the Immersion-based ones. Their SDK runs on Windows and they just released it for MacOS X in 10.2.3. I want to use these with pd. They are USB joysticks, and they do work under linux with the linux joystick drivers but since the SDK is closed source and they have released a linux version, you can't use the force feedback under linux, but 'iFeel' vibration stuff has been ported. I just got my joystick in today, and I have just started looking at the SDK... .hc

Re: [PD] mtof

Don't use mtof. The tool for the job is table lookup. Use the MIDI note number (with or without some suitable integer offset) as an argument for tabread, and you're good to go. I'm developing a Just Intonation synth in Pd. I've found that I had to horse around a little with the way I stored data in the table object: It's supposed to be 0-indexed, but the first data location seems to be ignored when it's loaded from a message object containing a list. Or something like that. YMMV. But it does work. My synth is set up to repeat 12 pitch classes in every octave, and it's still very much a work in progress, but if you'd like to fool around with it to see how I did the tuning algorithm, let me know and I'll email it to you. (It's over half a MB.) --Jim Aikin
