Merge tracks in parallel #63

Closed michaelmior closed 12 months ago

michaelmior commented 5 years ago

I have tracks for several different notes on the same instrument that I'm constructing independently. I get the current sound when I export these tracks as an array. However, I want the output to have a single track. When I use mergeTracks, I the tracks end up appearing one after the other. Is there any easy way to do this?

Hi @michaelmior,

Thanks for your message. mergeTracks should merge in parallel, but it's admittedly a bit experimental at the moment. Could you post your code so I can test it out and possibly figure out what's going on?

Thanks! Here's the function which generates each track and the function which merges them.

Please excuse me for butting in :)

Hi @michaelmior I was intrigued so I had a quick look, and your app appears to export MIDI files just fine...

Have I missed something, or how can the problem be reproduced?

michaelmior commented 5 years ago

The app does indeed export MIDI. However, each instrument is on a separate track where I would prefer them all to be on a single track.

I am having the same issue too.

grimmdude commented 12 months ago

Hi @michaelmior, I'm not able to replicate this currently. I've added a test for Track.mergeTrack() with a very basic example which is currently passing, but please let me know if you're still having trouble.

@xp2-882030kgz010602, if you could post some example code that illustrates the problem you're seeing I can take a closer look.

In the meantime, closing this one out for now.
