IEMLib status?
by Adam T. Lindsay 21 Nov '02

21 Nov '02

Hello Thomas, list, I was wondering what the status of IEMLib was. I've done some work using 1.12 to get it running on Mac OS X, and wanted to know if there was anything more up to date. Is there/will there be a version that takes away the appropriate GUI elements that have made it into PD proper? Am I duplicating anyone's work? Thomas, I'll send my changes under seperate cover. Mac users, the iemlib-darwin.tgz file has the make- and header-file modifications as well as compiled modules: <http://homepage.mac.com/atl/sw/> You should still download Thomas's Linux release for the abstractions, documentation, and source code: <http://iem.kug.ac.at/~musil/iemlib/> -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

Multichannel + asio
by matthew jones 21 Nov '02

21 Nov '02

hi, seem to be having some dificulty specifying multiple input and output channels in the startup arguments. pd -listdev gives something like (this is from memory) Audio Input #1: Creative Soundblaster Audio Input #2: M-Audio Delta 1010 Multichannel Audio Input #3: M-Audio Delta 1010 1/2 Audio Input #4: M-Audio Delta 1010 3/4 Audio Input #5: M-Audio Delta 1010 5/6 Audio Input #6: M-Audio Delta 1010 7/8 Audio Input #7: M-Audio Delta 1010 Mon Mixer Audio Input #8: M-Audio Delta 1010 SPDIF (The outputs are the same...) clearly, I want to be using the Delta 1010. for some reason, specifying pd.exe -asio -inchannels 3,4,5,6 -outchannels 3,4,5,6 means pd complains about illegal channel number, then takes a long time to register the quit command. so I try: pd.exe -asio -inchannels 2 -outchannels 2 same thing. In fact, if I try specifying channel numbers, it complains. I can get the Delta 1010 to work only by not specifying any channel numbers, and altering windows' default device to be Delta 1010. it works, but only 1 stereo pair. Any idea how to get multichannel I/O working?? cheers, M

Have you tried the -audiodev flag? Maybe -audiodev 3,4,5?

Architecture and construction of filters
by Chris McCormick 21 Nov '02

21 Nov '02

Hi, Just wondering how people build multi-pole filters in Pd? It seems that i've done about all I can do with just [vcf] and i'm wondering if anyone has any doc/pointers on building filters from scratch using the lowpass/bandpass objects or even links to basic filter theory for the layman explained. I've done some searches on google, but now i'm pretty much stumped. Basically i just want to get some fatter sounding acid happening. Suggestions? Regards, Chris. _________________________________ chris(a)mccormick.cx http://www.mccormick.cx http://www.sciencegirlrecords.com

library cpu load
by João Miguel Pais 21 Nov '02

21 Nov '02

Hello, I was curious about the following: when someone install several libraries but doesn't use them, do they keep space in memory? And if so, much (probably variable from case to case)? In a real performance, if somebody wants to minimize risks, is it advisable to unload all unecessary llibraries, or they are only used when the object is used? João Miguel Pais

[epochtime] - my first external
by David Sabine 20 Nov '02

20 Nov '02

Hello all, I'm exploring my very first external! But I've run into a snag. I'd like to build an external object which outputs the number of seconds since "epoch" when banged. Epoch is the beginning of time as the digital world understands it: jan 1 1970. Could somebody look over the following code and tell me why it works only after the FIRST BANG? Many thanks Regards, Dave S _____________________________ #include "m_pd.h" #include "time.h" static t_class *epochtime_class; typedef struct _epochtime { t_object x_obj; time_t t; } t_epochtime; void epochtime_bang(t_epochtime *x) { t_float f=x->t; x->t=time( NULL ); outlet_float(x->x_obj.ob_outlet, f); } void *epochtime_new(t_floatarg f) { t_epochtime *x = (t_epochtime *)pd_new(epochtime_class); x->t=f; outlet_new(&x->x_obj, &s_float); return (void *)x; } void epochtime_setup(void) { epochtime_class = class_new(gensym("epochtime"), (t_newmethod)epochtime_new, 0, sizeof(t_epochtime), CLASS_DEFAULT, 0); class_addbang(epochtime_class, epochtime_bang); }
