Hello,
this is not what i meant with the code but as i'm not testing the audio gens its all right, all i'm doing is see the MAUI changes with midi input.
Yesterday iīve seen the .onChange trigger thatīs what I was trying to do with the .value function.
I was trying to compile miniAudicle yesterday and it doesnt go all right, there is any libs I must install before I can build it ? I was thinking on try a little change on the MAUI API for supporting some kind of really knob like widgets (a ball with a mark at the 0 point that rotates itself from 0 to 127 or something like this) because my application will fit all of the screen just with the knob states if I use that rule as the marker.
Another thing I think is missing is a onscreen file manager to map my turntable and select samples from the midi controller, did you ever think on using GTK for this? because it support skins from itself (I dont know if cocoa can do this but i havent seen any Mac OS X apps with too much skin support) I thought it could be nice to make really good looking skins for any kind of chuck based machine.
Iīll send you more crash reports, there is something odd with the crashes, they donīt seem to hang on the same function, maybe its a little overflow the bcd is causing on the midi routines.
Thanks for your time
Piero

Hi Piero,
Thanks for your feedback on this. I've been looking into your crash
report from earlier and while I can see where the crash is occurring,
I can't quite figure out why it is occurring. So I don't really have
anything helpful to say at the moment, except that Im looking a
little deeper into ChucK's MIDI implementation.
Also, while it doesn't explain the crashing, this code of yours seems
a little suspect:

As far as I can tell, this will hang all audio processing until
knob_0.value() is 0--is that the desired result?
