Thread: Compact techno drum rack help
Rather than 2x Steppy, take a look at Varigate 8 or SWT16+ if you want to sequence in the rack, or Beatstep Pro would do a great job if you're looking for desktop sequencing
Otherwise a good midi to CV converter to keep sequening in-the-box. Mutant Brain is a budget favorite for drums, or FH2 + some expanders will allow you to build a completely customized Midi to CV configuration
