I have now isconnected the H9 from the Mac, tried it with only the pedal. Most of the algos/presets work, but all of those that I have already mentioned do not work. Tried with mono and stereo, still no sound from said presets & algorithms.
Using the H9 only (H9control disconnected), can you see all the presets and algorithms ?
Are you using a mono or stereo signal in and out ?
