Mopho NRPNs and MIDI Touch on iPad
2011-03-24 by larrykleinke
I all, i'm having difficulty getting NRPNs to control the Mopho properly using MIDI Touch on my iPad. In experimenting with OSC 1 Freq, i can't get midi touch to scan through the osc freq setting. It simply jumps to C10 from C0 the second i move the controller used for this. Same with any parameter i try it on. It simply jumps to its max setting. If anyone here uses MIDI Touch and has gotten NRPNs to work successfully, i'd like to know what i'm doing wrong. Here's some data to help: MIDI Touch NRPN available parameters: Channel MSB LSB Min Max Here's what i have them set at: Channel: 3 MSB: 0 LSB: 0 <--nrpn value for osc 1 freq Min: 0 Max: 120 I figured the min/max settings would cause the controller to scan through all osc freq values. Nope! Now, i did a side by side comparison of the data sent from the Mopho and MIDI Touch, here's what i get... Mopho: [C0] B2 63 00 B2 62 00 B2 06 00 B2 26 00 MIDI Touch: B2 63 00 B2 62 00 B2 06 00 B2 65 7F B2 64 7F -Larry
