Greetings Kyma-therapists,

I'm struggling a bit with what seems an elementary endeavor. I have a 10 channel midi file that I would like to play back and be able to do simple alterations in realtime, like transposition to each track, mute on/off of each track, and adjustment of the tempo. The midi info would be sent out to the synth. Any direction on how to best approach?

Start with a Mixer.
Put a MIDIVoice into it. Set the MIDIVoice to channel 1, and check the 'from MIDI file' radio button.
Drag an MIDIOutputEvent into the input of the MIDIVoice. Set its parameters to !KeyPitch, !KeyVelocity, !KeyDown, and Channel 1.
For transposition, add something to the pitch, for example
!KeyPitch + !Interval1 nn
For muting, multiply the !Velocity by a variable, eg.
!KeyVelocity * (1 - !Mute1)
Drag 9 copies of this MIDIVoice into the Mixer Inputs field. Then modify the parameters to read MIDI channels 1-10 and output on channels 1-10, etc.
I can't think of an easy way to do the tempo change to a MIDI file at this time.

Tempo control over MIDI files is one of the things on our list.
