I use the Moog model D app with my i pad, and I mostly use the Dave Smith Evolver for live gigs. I used the UNO synth on one of these. I also like the arturia microbrute, arturia Micro Freak, and the Roland se-02 is also nice. Though mine seems to to go out of tune in extreme registers.
@@Noidal77 I had trouble with my SE-02 going out of tune, too. I thought it was the cv tune setting but I never could get it dialed in. Ended up trading it for a second ZOIA :)
