Welcome to the Squarp Community
@Ezmyrelda posted some excellent info for you to get your started.
If I may chime in with:
- Remember MIDI is not Audio and Audio is not MIDI. (MIDI is data - as in what keys you press, how hard, etc; Audio is made by your synths from the data)
- The Pyramid basically (or perhaps more accurately: “conceptually”) replaces a human playing a keyboard
I have been castigated here for stating this, but I’ll reiterate because in reality I am an idiot and most practices I employ are to circumvent stupid my cornucopia of inane mistakes and eye rollingly banal oversights:
- The only synths you need to connect to data going IN to the Pyramid are ones you want to control or record data. That is, you can set up the Rev2 as your sole controller and use it to record MIDI data that is played on your Minilogue or TR8.
Sometimes it’s easier to have them all routed in.
Sometimes it’s easier to just use one.
And by ‘easy’ I strongly recommend factoring in “makes sense to you and your workflow based on your experience, knowledge, and gear”. (ie “easy” for one person with the same gear is not the same as easy for another)
There are many ways to hook up the gear you have listed.
Start with one or two and get used to how the Pyramid interacts with them and how you might approach your workflow - because there are many ways of approaching it. You get to define your own! (Which is super exciting!)
Also, if you’re not familiar with MIDI, I strongly suggest reviewing some MIDI Tutorials online. There are many. After you get familiar with a few things, it may start to seem daunting, but do not fret. A good place to start is MIDI.org for Tutorials. Random googlizing will help flesh out the rest, I trust.
And finally, you say “without buying more hardware (midi merger)”.
Well, things like mergers, thru boxes, event processors, etc are gear, too. They make things a little bit more…you, IMO. That is: Pyramid + Synths = entree, side dish, etc. More complex routing, event processors, etc = Seasonings!
