All,
I'm curious how to use MIDI clock effectively in ChucK, in two main use cases:
From a sample-rate-based timer in ChucK, how should I send out MIDI clock?
while (true) {
10::ms => now;
// send MIDI clock
}
or
TimeSignature.common(120) @=> TimeSignature ts;
while (true) {
ts.e => now;
// send MIDI clock
}
or (this one allows the caller to modify the tempo later)
TimeSignature.common(120) @=> TimeSignature ts;
ts.eighthProvider() @=> EighthProvider e;
while (true) {
e.evaluate() => now;
// send MIDI clock
}
From receiving MIDI clock messages from an external source, how should one adjust the BPM in ChucK?
MidiIn min;
MidiMsg msg;
TimeSignature.common(120) @=> TimeSignature ts;
while (min.recv(msg)) {
// if is clock … {
/* new BPM */ => ts.tempo;
}
}
I would imagine I would want to window over the last n clock messages to average?
Thanks in advance,
michael
