I'm a fan of electro, electronica, in fact anything electronic.
I have a lot of VSTs.
Hardware wise at the moment I have (approximately).
Volca Bass (+ Midi mods)
Volca Beats (+ Midi, snare and line out mods)
Roland JD900 + Vintage synth
Roland XV5080 + several expansions & sampling RAM
Novation X-Station (like a KS synth and a great controller)
Roland Alpha Juno 2
Sequential circuits six-track
Ensoniq EPS16+
Casio CZ101
Yamaha TG500
Korg Poly 800 - soon to have Hawk800 and Atomahawk/moog slayer mods

Pod effects processor
Many VSTs etc
And I look out for a cheap MicroKorg at some point.
I wonder about the volca keys. I'm considering some other kit. TR-8, SH-32, TG77, D-550 etc. I like stuff with Midi that I can store patches on, old is fine. Digital is fine even, but analog character is important, hence an accumulation of outboard gear.
I'm a bit fan of analog, but not storing patches makes it hard for me to switch between tracks I'm working on (I'm fickle in the way I work).
What would the MS-20 mini bring to the table from the above stuff I've collected?
Would it be worth adding it, or considering an analog alternative such as minibrute or even novation bass station 2, for example?
