I’ve got a Microbrute and do find it a bit harsh, could be tempted to sell. Have got or have had Novation Supernova, Waldorf Q, Little Phatty, DS Prophet, Spectral Audio Neptune and what I’ve learned I dislike is menu dipping and when multiple functions are assigned to one control and you have to keep cycling through.
I do find myself working mainly ITB but my Juno 106 gets a hammering. I think I’d be looking at a classic synth myself, or maybe an Access Virus or Monomachine depending on what it’s primary use will be. I’ve built two Mutable Instruments Shruthi which are good fun and an Ambika could be a good call if you’re handy at soldering.
Check this studio tour to get a good feel of some retro gear.
And check my shizzle.
