There are a couple of things to check on your DSI Mopho synth to ensure you can control it from the Mopho Control app. Please confirm these settings if you are having trouble getting the app to work.
1. Make sure the synth is set to receive NRPN by setting MParam Rec to either All or NRPN.
2. Make sure the MIDI channel is the same on both the app and the device.
3. If you want the app to update when controls on the device are moved, make sure that MParam Send is set to NRPN.
If, for any reason, you are still unable to control the synth please contact us via our support email.
