Hi, I use the midibox with my Rm1x, but I came to the conclusion that when I select a track, all the incoming data will be applied for the selected track, and not on all midi channels. This occurs when RecMode is selected at Echo Back (second page, utility). When choosing Thrue at Echo Back, the midibox works fine on every channel (each knob will change the cutoff for each channel, for example). But at this mode, all the notes played at the midi keyboard (chained behind the midibox) will apply to a fixed channel, and not to the selected channel! I want 16 knobs of the midibox control the cutoff of each channel, and I want the keyboard to play the voice of the selected track. Any work-arounds for this? Regards, TraiZor
