MIDI port aliases
by Bruce Murphy 10 Jul '06

10 Jul '06

UNder Mac OS X, CoreMIDI provides really nifty aliases for ports which are plugged into named devices. This permits them to be easily identified by users with multiple interfaces. These mappings are set up in the audiomid tool by creating devices and setting up wiring The mappings are also useful for named virtual ports created by other MIDI aware applications. COreMIDI also provides an interface for getting the name of the MIDI device providing the port which can further aid identification. IT would be really nice if the chuck probe stuff actually provided this feature. It would be equally nice if a MIDI port open had a "name matching this string" facility, so devices could be moved around between interfaces and provided you had updated audiomidi, all the chuck software looking for that device would Just Work.

filter
by Atte André Jensen 02 Jul '06

02 Jul '06

Hi I'm just a simple guy, and I haven't got a clue what's up with the filters available in chuck. Poles and zeros and stuff... I'd appreciate if someone could: 1) Give an example of how to set up (something that in my simple brain is called) a low pass filter with/without resonance and a highpass filter with/without resonace. 2) Could direct me towards mind-expanding online information that might allow me to actually understand a fraction of what's going on? And while we're at it: I see no examples using either sawosc or sqrosc. I know how to use those though (just need some filters), but, still at the risk of seeming extremely conservative, wouldn't a classic, analog synth style patch (saw > low pass filter > envelope) or two be a nice and possible addition? Maybe someone even has such a simple example (involving filtering) that I could take a look at or we could throw on the wiki? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

syntax errors + emacs mode
by Atte André Jensen 30 Jun '06

30 Jun '06

Hi I use the emacs mode a lot. One of the really un-nice things is that if I add/replace a file with syntax errors from emacs, the error message doesn't show up. If I do it in a terminal the error messages do show up. Other errors when adding/replacing do show up just fine. Any ideas what's the difference between syntax errors (from emacs point of view) and how this could be changed? Is it the emacs mode or chuck that's to blame? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

pan2.pan
by Atte André Jensen 30 Jun '06

30 Jun '06

Hi I discovered a mistake in the documentation. On http://chuck.cs.princeton.edu/doc/program/ugen_full.html#pan2 it is suggested that .pan goes from 0 to 1, while in fact it goes from -1 to 1, with 0 being center. I didn't try but I bet other ugens with pan work the same way. Should be updated in the documentation... -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

chuck on multiple processors
by Atte André Jensen 30 Jun '06

30 Jun '06

Hi Is it currently possible to run chuck on multiple processors? Dual core? Clusters? If so, where can I read about it, if now, are there any plans in this direction? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions

ADSR modulation question
by Atte André Jensen 29 Jun '06

29 Jun '06

Hi there I'd like to setup a patch like this... noise n => biquad f => dac; ...and then have an adsr modulate f.pfreq. I know how to use ADSR for modulating volume (just send it through) and I also know that the modulation can be done with explicit timing using a loop and chucking to now at "control rate". But is it done with an ADSR? -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions
