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