I think it's about economy on the DAW side. Fewer MIDI tracks, fewer channels to manage.recursive one wrote: ↑Fri Jan 04, 2019 2:18 pm When you have a patch with two or more layers each of them having its own seq/arp pattern, most likely you actually have two distinct instument parts, which you will want at least to process separately in an actual mix. So you need your synth also to be multitimbral. But then why not just to use two instances? This is much easier to handle when you are making an actual musical piece in a DAW and not an "impressive" preset just for the sake of it.
Sounds like a good job for a plug-in like Xlutop Chainer.
