Hello,

I am currently working on a synth for my game controller, this is my first patch and I am very learning the basics.

For the moment the patch is a 8 voices polyphonic synthesizer working with a bunch of phasors. With my controller I have 8 key representing the major scale, the up and down buttons change the octave and right and left rise or lower the note by a semitone. Having this PS2 command, the central joysticks give the possibility to slide between tones a bit like a theremin.

Though i have a few question :

I wanna adopt this little thingy for a midi keyboard with a 16-polyphonic synth.
What is the best way to have polyphonic synth?
Is there a way to have a dispatcher that will send the notes to those synth?

There should be a possibility to pass from [phasor~] to [osc~]. I do not want to surcharge the cpu and wonder if when 0 is send to the frequency of [osc~], does the cup it still use a lot of cpu?

Thanks.

Take a look at the [poly~] object. It also might help to see it implemented in help->browser->3.audio.examples->D11.sampler.poly.pd.

I don't entirely understand what you mean here, but if you don't want [osc~], or any audio objects, to task your cpu when they are not really active, you can stick them in a subpatch and turn audio processing off in that subpatch using [switch~].

Thanks for the information.

I am taking into pratice your advices, I'll post the patch as soon as it's done.

Here comes the patch.

I have quite an annoying, I can't seem to get around it. Whatever button is pressed on the joystick, the message is sent twice by the HID object.

Eg :

print: btn_4 1
print: btn_4 1
print: btn_4 0
print: btn_4 0

Is it a normal behavior and should I just filtre it?
Or is there a better way to launch the hid object?

Thank you.
