tuning_midi.pci.zip
 
I have been attempting to edit the tuning.pci tool so that it could be possible to test a tuning directly on an external / software synthesizer.

In the Response to the 'waveformChoice hasChanged...' Trigger I test if the MIDI button has been selected :

(waveformChoice = 'MIDI') ifFalse: [Waveform := waveformChoice.
PlaySound value.
SetEqualTempered value.].

(waveformChoice = 'MIDI') ifTrue: [Waveform := 'sine'.
PlaySound value.
SetEqualTempered value.].

If the MIDI button is selected I would like to redirect the MidiIn commands to Kyma (which would otherwise play a sample/sine or saw) to MidiOut commands [initially] on channel 1. (The code for when MIDI is true is currently set to play a "sine' for testing purposes.)

I'd be really grateful as to what replacement code / messages are required to achieve this.

Well, one simple approach might be to use the Tuning Tool to create an example. Then copy the expression from the Frequency field of the example and paste it into the Frequency field of a MIDIOutputEvent (setting the Gate to !KeyDown, and Amplitude to !KeyVelocity). If you send one voice per channel, the MIDIOutputEvent will automatically send the deviations from integer notenumber as a PitchBend to the external synth.

I have used the MIDIOutputEvent sound for this in the past; which is fine, but testing a sound directly from the tuning tool via midi would be great if it were possible.

Are there any midi message objects in smalltalk? (Isn't everything in smalltalk is an object?) I couldn't find any suitable messages in 'Kyma X Revealed'.
