This includes a mod for MIDI (in/out/thru) as well as mod switches for the VCA and VCF to provide additional sound quality options. I've regularly used the MIDI input for professional recording from various DAW software environments. It also works great with my Doepfer Dark Time or Kenton Pro Solo MkII for triggering and MIDI performance options.
The synth was professionally tuned up by DFX and sounds great. Please take a look at the provided Youtube demo that shows some of the many features. On that same Youtube channel, you can find other videos/tracks that feature the Jupiter8, including "Jupiter Sounds" (rich synth strings) and "Model DJam" (where the arpeggiator is featured)."
