I have a sequencer built in AudioKit made up of various AKMIDISamplers to create a 12 beat sequence. This works great. Now I would like to chain multiple sequencers together and have the sequences play one after another (instead of at the same time). I keep the Sequencer Formulas in separate functions. I am still getting a handle on Audiokit.
Cheers and Thanks!
