[sc-users] AudioUnitBuilder, Virtual MIDI Instrument, Logic 9, Logic X & Finale

Dear advanced users,

I have tried to build a AudioUnit virtual MIDI instrument using AudioUnitBuilder in SC3.6.6 in OSX 10.9.5.

The code is as follows:

(

var name, func, specs, componentType, componentSubtype, builder;

name = "www";

func = {

|vol, midinote|

var notes, on, off;

p = Platform.resourceDir +/+ "sounds/a11wlk01.wav";

b = Buffer.read(s, p);

SynthDef(\help_Buffer, { | out = 0, bufnum, freq, amp|

var sig;

sig = PlayBuf.ar(1, bufnum, freq/64*BufRateScale.kr(bufnum))*amp;

Out.ar( out, sig )

}).send(s);

MIDIClient.init;

MIDIIn.connectAll;

notes = Array.newClear(128); // array has one slot per possible MIDI note

on = MIDIFunc.noteOn({ |veloc, num, chan, src|

notes[num] = Synth(\help_Buffer, [\out, 0, \bufnum, b, \freq, num.midicps, \amp, veloc * 0.00315]);

});

off = MIDIFunc.noteOff({ |veloc, num, chan, src|

notes[num].release;

});

q = { on.free; off.free; };

};

specs = #[

[0, 0.5 , \Linear, 0.1,\LinearGain ]

];

componentType = \aumu;

componentSubtype = \CGPG;

builder = AudioUnitBuilder.new(name, componentSubtype, func, specs, componentType);

builder.makeInstall;

)

SC3.6.6 successfully created an AU instrument from the code above.

I have tested the plugin under Logic 9, Logic X and Finale.

Logic X does not recognise the plugin. Could be the compatibility between 6bit host and 32 bit plugin?

Moreover, in Logic 9 and in Finale I don't hear any sound.

What should I do to have an AU instrument using SC?

Is the code above wrong?

Any help would be greatly appreciated!

Best regards,
