Does anyone of you control a Behringer REV2496 (V-Verb) via MIDI? I have a problem with NRPN messages, can only control the buttons COMPARE and BYPASS, not the TAP and not any parameter. According to the MIDI Iplementation manual almost everything should be controllable. I see what the unit sends and that it receives my messages but it does not react to mine. The unit itself should be ok because I have two of them and none likes my MIDI although I send exactly back what they show me. Only me or a general problem? REV2496, Firmware 1.2 I searched the web to no avail. Did not ask Behringer yet.
