Fw: [PD] Maya Asio problem
by João M Pais 26 Aug '02

26 Aug '02

Hello, I'm trying to help a friend which uses pd but is not on the list. I would like to ask the following question: I'm trying to use a Audiotrak Maya44 soundboard to get four outchannels. We use the normal drivers in windows 98 and it works, but in pd .34 the output comes only in stereo, either between the 1st and 2nd channels, or 3rd and 4th, or both mixed (1+3 and 2+4), never in 4 independent channels. I'm not sure if the problem is with the configuration flags, or a problem with the driver. Should I use "pd -channels 4", or "pd autiooutdev x,x"? Should I also use "-asio"? I've tried with the option -channels 4, both with no result. Should this option only say how many channels are necessary, or specify also which? Does anybody use this soundboard, and if so, has met this error? The card is ASIO compatible (version 2.0), but does pd uses the asio device automatically, or is necessary some kind of installation? (as I said, normal windows programs work with 4 tracks) Thank you very much, Klaus Schedl

RE: all notes off / PANIC-button (lsw)
by Norbert Math 25 Aug '02

25 Aug '02

hello, according to the MIDI spec, if you send a value of 0 to controller 123 it is (should be?) interpreded as an "All Notes Off" command. send this to all MIDI channels. but in the real world, you might need a more expensive patch. the only way to safley turn off all hanging notes is to subsequently send a "Note Off" (or "Note On" with Velocity 0) to all MIDI notes through all channels. (creating an external which makes use of the "running status" compression protocol would decrease the amount of data) lg norbert > Dear list, > > i wonder how to send a all-notes-off-message to a midi object like = > noteout or vst~. > I've got those "standing tones" from time to time, and i like to patch a = > panic-button, > to stop all currently playing notes. > Is there any way??? > > keep on > leo >

all notes off / PANIC-button
by lsw 24 Aug '02

Dear list, i wonder how to send a all-notes-off-message to a midi object like noteout or vst~. I've got those "standing tones" from time to time, and i like to patch a panic-button, to stop all currently playing notes. Is there any way??? keep on leo

oh yeah
by J. Scott Hildebrand 24 Aug '02

the other question is this; i will end up having my convolved samples in an array like: aleftout[256] arightout[256] what i need to do now is read those out to the soundcard, and originally i thought something like this would work: for(int read=0; read<=255; read++) { out1++ = aleftout[read]; out2++ = arightout[read]; } well it doesn't work, and i'm not really sure what the mechanism is to get the samples back into the in/out arrays and then sent to the soundcard. any help is appreciated greatly! scott -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

Array Size
by Chris McCormick 24 Aug '02

24 Aug '02

Hi, I'm probably missing something really obvious here, but is getsize the easiest way to get the size of an array? The example provided in the help seems overly complex. Is there an easier way than doing this weird traversing the table thing?

two questions
by J. Scott Hildebrand 24 Aug '02

24 Aug '02

how do i use the block~ object? i would like for pd to take 256 or 200 samples at a time, but i'm not sure about the overlap factor or what it does. i forgot my other question, so i'll just send another email when i remember :) scott -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

installing GEM
by J. Scott Hildebrand 23 Aug '02

23 Aug '02

apparently the problemo is that GEM doesn't want to compile with the most recent versions of some of the libraries that it requires be installed. if you have experience with this, and have libraries that are older and do work, can you please email me the needed files? merci, scott -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

convolution code error
by J. Scott Hildebrand 23 Aug '02

23 Aug '02

here is the code for my convolution project that i'm working on. i sent an earlier email to the pdlist, but i don't think it'll go through because it's over 2MB which includes a bin file. anyway i found out where i'm getting the seg fault: for(set=0; set<=255; set++) { aleftout[set]=(*in1++); /*brings in 256 samples from input*/ arightout[set]=(*in2++); } what i think is happening is that aleftout and arightout are float arrays, and what i'm trying to pass into them are pointers to floats. everything in my code is happening in the while(n--) part of it, so i think i just need to make some type conversions there. i believe all of the fftr4_ functions take floats, so i need to convert from pointer to float, and then again from float to pointer. thanks in advance to anybody who can help me! i'm just not sure how to do this. scott -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 -------------------------------------------------------------------- ---------- Forwarded message ---------- Date: Tue, 20 Aug 2002 14:27:02 -0700 (PDT) From: Jeffrey Hildebrand <jscotth(a)nyquist.cipic.ucdavis.edu> To: jscotth(a)ucdavis.edu
