Yo man....how's it going? :-)
Well about the second Moskwa...I don't think I'd do it because I have a Elektron Analog Four and I use that to get up to 64 steps.
The Moskwa is awesome but I think it's all I need in my system. Althought I would love if the Rate could be modulated. :-)
The Maths is incredible. I want to say this without sounding like a sales pitch but I heard it said somewhere "every system needs a Maths" and this is totally true!
I was a bit intimidated by the Maths initially because frankly there were a lot of terms, discribing it's functionality that I didn't understand during my reasearch.
I bought it anyway thinking I'd give it a shot and I'm happy to report that once I got my hands on the Maths and started tweeking knobs and reading the manual
things became very clear. All I can say is that it does so much I would NEVER want to be without it.
