How to play note at the time I want

[baigua]

I found FlutterPcmSound is single threaded.

so what should I do, if I want my note not play one after another or play at the same time, but like this:

[chipweinberger]

turn on multiple notes at the same time in the synth

[chipweinberger]

timing is controlled by rendering more samples

1. turn on note
2. render 0.2 seconds
3. turn on another note
4. render 0.2 seconds
5. et

Thanks a lot, I don't know if my understanding is correct?

[chipweinberger]

you need to feed every buffer, not just the last one

or combine the buffers into one big one

[baigua]

sure, the feed part should be like:

Future.delayed(Duration(milliseconds: gapTime), () {
FlutterPcmSound.feed(PcmArrayInt16(bytes: buffer.bytes));
}

just make sure, if I don't noteOff any notes, they will keep active in the following render.
