There’s not very much to Chain mode. It’s just badly explained in the manual and I’ve never used it in anger. Song mode is much more powerful and is explained pretty well by Cuckoo in his AKeys sequencer video.

It’s quite near the end, so you might want to skip. It’s quite a long video as he covers the sequencer in detail.

I’ve had requests for some sound design tips. That would involve the envelopes, so keep a look out. Very glad you enjoy the tutorials!
