Just tried my MIDI modded Monotribe in the mystery box slot, it does do the translation, but more often than not the MIDI of the penultimate note played on the MS is sent via the MT, the MT will faithfully use the HZ/v signal and track the MS, but the MIDI is compromised, note though, that there is a way to calibrate the MT and this may improve the cv>midi accuracy, but I haven’t thrashed that out
see here for earlier attempts ( I just remembered trying this before )
