Various USB to Midi and CV options:
USB Midi hosts to Din Midi:
Kenton MIDI USB Host MkII
Miditech USB MIDI Host
BomeBox
SIPARIO
Retrokits RK-005 USB MIDI HUB
the Retrokiits RK-004 could be used as well with the addition of Raspberry Pi
Blokas Midihub – In Beta or nearly so.
There are Raspberry Pi ways to do this too.
Midi to CV
Expert Sleepers FH-2
Expert Sleepers Disting mk4 – Not enough channels alone
the Expert Sleepers ES-8 can be used to do CV interface too, it’s an audio interface.
Intellijel µMIDI 1U together with the µMIDI Jacks 1U
Polyend Poly
No doubt there are other options for both categories. (And little doubt i’ve made errors with this too, so check and comment or PM and i’ll update this .) It would be nice to have the two functions together somewhere – wait i know where, the complete Expressive E Touché.
