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 i´ve seen the .onChange trigger that´s what I was trying to do with the .value function.

Yes-- in fact, .onChange is redundant: knob_0.onChange() => now; is the same as knob_0 => now; but either method is fully supported.

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 ?

You shouldn't need any libs. It looks like there is an error in makefile.osx... argh. If you delete the '#' character on line 144 of that file, it should work. 'make osx-ub' doesn't have this same error, so that will work, but it will produce a universal binary. So, Ill fix the source distro online also when I get a chance...

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.

OS X has a circular knob user interface widget that we were planning on supporting. This knob uses the same Objective-C class as the slider, so if you're handy with Cocoa you could pretty easily switch the sliders over to knobs.

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.

Yes! the user interface element API definitely needs a lot of expansion--multisliders, file selection dialogs, menus, text fields, etc., are all planned, but unfortunately there are only so many hours in the day... Skinnability would be cool, but I don't think it would be easy to combine GTK and Cocoa code bases on OS X. Also, GTK on OS X requires X11, which unfortunately is kind of a second-class citizen on OS X, and isn't installed by default. It is possible to compile the wxGTK version of miniAudicle on OS X though--if thats something that might be a step in the right direction, let me know. Its pretty easy if you already have GTK and wxGTK.

I´ll send you more crash reports, there is something odd with the crashes, they don´t seem to hang on the same function, maybe its a little overflow the bcd is causing on the midi routines.

Hmm, yeah, keep 'em coming! Do you have any idea what kind of actual MIDI messages the BCD is sending? thanks! spencer

Thanks for your time

2007/4/13, Spencer Salazar : 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:

...

public void Distortion() { while(knob_0.value()) { knob_0.value() => float value; value * 39 => f.pfreq; // value => i.next; } min => now; }

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

Hello,

I don't know if this is the right place to put this on but, this code is crashing randomly on my tests:

MAUI_View window; MAUI_Slider knob_0;

window.size(300,300); window.name("Test"); window.position(0,100);

knob_0.range(0,127); knob_0.size(150,knob_0.height()); //cut_knob_0.position(0,0); knob_0.name("Knob 0"); knob_0.displayFormat(MAUI_Slider.integerFormat); // impulse to filter to dac

Impulse i => BiQuad f => Pan2 p => dac; // set the filter's pole radius .99 => f.prad; // set equal gain zeros 1 => f.eqzs; // set filter gain .5 => f.gain;

window.addElement (knob_0);

window.display();

1 => int device;

MidiIn min; MidiMsg msg;

if( !min.open( device ) ) { <<< "erro ao iniciar device:" , device >>> ; } else { <<< "device inicializado:" , min.num() , " -> " , min.name () >>>; }

public void controlKnob_0() { while(true) { while ( min.recv(msg) ) { msg.data1 => int msg_1; msg.data2 => int msg_2; msg.data3 => int msg_3;

if(msg_2 == 3) { knob_0.value(msg_3); } } min => now; } }

public void Distortion() { while(knob_0.value()) { knob_0.value() => float value; value * 39 => f.pfreq; // value => i.next; } min => now; }

spork ~ controlKnob_0(); spork ~ Distortion();

while ( true ) { 1.0 => i.next; // Std.rand2f ( 250, 5000 ) => f.pfreq; Std.rand2f( -1, 1 ) => p.pan; 100::ms => now; }

What i'm doing is mapping one knob of my bcd2000 to a MAUI Slider, to see on the screen the position of the knob, as i've posted here before, the midi itself is hanging up using this controller, but I think it might be something i'm doing wrong, anyone can point me out a clue on what could be it?

Thanks
