    Yes for a commercial project of this! Do you think it would be feasible to make a voice expansion project using clone JP4 cards to upgrade existing machines? Cheers.

      Hi, unfortunately its not very practical to add more voices to the JP4. There is nowhere to put them in the case, and the keyboard scanner only does 4 voices. It would be possible to build a 4 or 8 voice rack or boat synth using the new cards and the new patch programmer we are working on. Best Regards Rob

  • Hi there,

    Just leaving my comment that if these cards ever became available I would probably be up for 5 of them for my tech to build.

    Regards

    I would buy 4 of them to make an 8-voice JP4 if someone can figure out an expansion. Perhaps a few more as backup.
    Best of luck with this project.

    @amsynths definitely challenging but there’s a lot of air inside the JP4. I can think of at least a few ways to place more cards inside, at least a couple of them for sure. You are right about the key assigner though, it would have to be a new board altogether, like the one Lazlo Kovari is developing for IO V2 now. But 6-voice Jupiter-4? Where do I sign?
