What an amazing setup! I am waiting for IME Stillson Hammer MK3 to come out and see what Scott adds to it. I like Metropolis but it only has one gate output a deal breaker for me. Eloquencer has 8 gate outs and many features as does the 512 Vector. In the short term, I may get a Beatstep Pro and pair that with a Keystep external sequencer for drums to avoid having to buy another large case right now.
So do you have experience with WMD Metron? Does it not have various operation sequencer modes like reverse and ping pong?
I am waiting for covid to end so I can visit a synth shop and try out various modular sequencers as I hate returning gear.
