I only know @verstaerker that has both, shared this picture:
He may have some insight.
Yes with a (long, sorry) but. First, each track in Multitrack has independent MIDI channels, so you can use the rest for another 4 mono instruments or sample triggering. Each track has independent length, time division, playback direction, etc.
More conceptually speaking, you won’t use Multitrack to make chords (you can ofc), you would use Chord or Poly mode that you can load in any of the 4 slots or in several at once. The reason is mostly because the workflow is much better suited for that end, and you have the same amount of voices out that in Multitrack, just more cleverly linked/presented (plus the keyboard and arp voices on top, independent for each sequencer so you can play (hold) 4 arpeggios at the same time). Additionally Chord mode has an independent MIDI channel for the root note (1 or 2 oct down), being able to run another instrument using only one sequencer. Multitrack is best suited for drums, sample launch or several mono voices with Euclid, a ton of randomisation and MI Grids engine under the hood.
The sequencer mode thing is quite unique because each mode is very focused in certain tasks to make the best out of it, and they overlap more general features with the other modes so nothing goes missing, this way you choose what your 4 sequencers do. Instead of forcing a fixed architecture it becomes modular to best fit your setup. Stochastic mode is not for you? that’s ok, you won’t see it in the UI other than in a list of modes, it’s virtually non existent in your machine. You enjoy Multitrack? let’s add 3 of them.
This is also a misconception. I can’t judge directly because I know the workflow and how it evolved since the beginning, but new users are saying that it’s very accessible, but an improvable manual.
True that some don’t click that fast with the workflow, but I know a few don’t even read the manual.
Any new instrument requires certain expertise (I’d say it’s a couple of days), specially with performative and feature deep ones. Loopop review is not a current reference, 1 year from that prototype and lots of updates made a huge difference.
