"synths may only be in one instrument or channel at a time" error from .sound.track:setInstrument()?

[AdamsImmersive (Morgan)]

I fear my brain must be stuck in some misunderstanding. This simple test script generates the error...

synths may only be in one instrument or channel at a time

...on the final line, setInstrument

But that line isn't assigning a synth to anything... it's assigning an instrument to a track. And I don't see how anything is being assigned to more than one of anything. What does that error mean?

local synthObj = playdate.sound.synth.new()
local instrument = playdate.sound.instrument.new(synthObj)

local noteTrack = playdate.sound.track.new()
noteTrack:setInstrument(instrument)

TIA!

Crash: synths may only be in one instrument or channel at a time

The problem is a bug (introduced in 1.13.0, I think) is causing snd.instrument.new(synth) to return the synth, not the instrument. You can work around this by doing the old style instrument[i]=snd.instrument.new() instrument[i]:addVoice(synth[i]) Thanks for catching this! It's filed and I'll get a fix in the queue as soon as we can get the current backlog flushed out.

Thanks for the reminder to get the fix pushed to the merge queue. I'd been holding onto that until we got things moving again.

Cool—for now, I see the workaround in that other thread
