Hey bass player - No problem about the "noob questions". This app is deep so just take it slow, I find new things about it all the time! Okay it should be all good.
ON MIDI Through or OUT and LEARN - Cant remember if they are set to MIDI out or Thru but are you seeing the knob move on the iPad when you move it on the pedal? If not then switch to the other option. You should see the changes you make on the hardware reflected on the pedal. Then you can use learn, when you create a knob, under channel - cc in the midi tab is a learn button, click that and turn the knob on the pedal you want the knob on the iPad to control and MDP2 will recognize the Channel and cc of the knob, this makes designing a layout so much faster.
Please let me know if everything works for you now.
There may be glitches in the pedal itself I'm not sure - I've encountered one glitch with the Enzo and MIDI control that I beleive is hardware related and I emailed meris about it, mostly just the mode light being on the wrong mode when I change the envelope button, which is confusing. it is a great pedal but maybe a little rushed out, I was surprised as the other meris pedals I have are flawless but I did order from the first batch this time.
Fixed the placement of PC+ - as well.
