Hi!

Having some problem receiving sysex dump via USB.
C6 says (after correctly recognizing instrument) “receiving: 0 bytes”. A4 says “sending…” and supposedly finishes it after a short while, but it’s still 0 bytes indefinitely at the receiver side.
midi out on a4 is set to ‘usb’
I have no problem sending sysex (soundbanks) on the other hand.
Any help would be appreciated!
