MIDISampler issue with XCode 15.3RC

[NickCulbertson]

I just submitted a new PR to AudioKit that should fix the issue. I updated the enableMIDI method on AppleSequencer.

I'm on Xcode 15.0 and it's working there so it must be version specific. Is the Music Toy example working? Those examples are pretty similar. Are there any clues in the console?

[matts9000]

Yes, it this issue appears only with Xcode 15.3 - it does not show up to Xcode 15.2
I just tried with the Music Toy, and it has the same issue - no sound after start playing.

I just downloaded the Xcode beta and I'm getting the issue too. If you create a MIDICallback instrument it works, but not with drums.midiIn. I'll add a MIDICallback in the Drum Sequencer as a workaround, but I'll leave the Toy example as-is for now since it might still be working in the release version. The workaround for Drum Sequencer should work on the Toy example too if the Xcode release borks things.

For me, MIDI playback is completely silent when building on Xcode 15.3. The same code works flawlessly with Xcode 15.2. It fails silently — no errors are thrown, so I'm not sure how to debug it.

@michaelsteeber Is the DrumSequencer example working? That one uses AppleSequencer with a MIDICallback to play the instruments.

[NickCulbertson]

I'm downloading the new Xcode version now. If I can't figure it out, I'll update all the Cookbook examples to use the MIDICallback. There is also a second Sequencer class in AudioKit that isn't facing this issue. An example of that is in the Arpeggio recipe.

[michaelsteeber]

DrumSequencer is working when building on Xcode 15.3 now, older versions of the Cookbook are silent built on 15.3. My project also uses AppleSequencer and MIDISampler.

[NickCulbertson]

This should now be resolved in the latest version of AudioKit and the Cookbook.

Tested today, it works great.
