Phase Distortion you say…

I struggled programming anything useful on my CZ-101, but Patch Base made things so much easier..
I’d considered selling the external cartridge, but even that’s full now..👍

Broken: Midi wired connection does not work

As title says, connected to iPad using usb c hub with usb connections and no device is detected for the Roland JDXI. Have also made sure usb connection is set up on the jdxi ‘correctly’

Great app!

Love using this app on iPad and Mac. it's breathed new life into my Roland XP-30

Brilliant!

I’ve got about 5 editors / librarians now. It does take a bit of getting used to, but breathes life back into your old rack gear. My D550 has never been happier, and the JV1080 sounds amazing! The only reason it’s not a 5* review is I have some ongoing troubles getting the TX802 running - but have had very little time to try to resolve. I’m sure it’s me, as when the other editors are set up, it’s a great bit of kit.

For pricing, I think £30 is fair, considering the power of this thing, and compared to the price of a second hand knob programmer for each synth!

Happy twiddling everyone!
