I received my arches and it looks great so far. Anyway I am having a huge problem to integrate it in my setup. I connected a Prophet X synth via MIDI DIN cable to the MIDI IN of the arches. Setting the clock source to MIDI, MIDI CLK OUT to ON and MIDI I/F to DIN does not forward my clock information to the CKIN plug. When I switch to INTERNAL, the internal clock pulse immediately appear ar the clock plug. This is critical for me, as I need another device to be the MIDI master clock. Can you confirm this bug?
