Juno-DS88 difficult C12 creation of remote control device

Hi, I’m mimicking Greg Ondo and Dom Sigalas vids on creating a remote control device with my Juno-DS88, but am not successful.

I see MIDI activity into Cubase when i turn a knob/ push a fader, but the created cartoon of the control surface I built responds erratically.

Anyone here use the Juno-DS88, if so could you please help, maybe show a pic of your MIDI ports and Mackie port connections?

Thank you!

PS: Bluetooth MIDI connection, next I’ll try the DIN connector …

I’ve made significant progress, will update response later
