The core can be used in the MIDI Merger project right? How is the MIDI in connected to J4? I tried to breadbrd a circuit as in midimerger.pdf but had no joy…
How is the circuit powered? Via the midiline or does it need additional juice?
yes, the second MIDI In is connected to J4 via an optocoupler. The circuit cannot be powered via MIDI - this would require some circuit changes and mostly it will not run successfully (I tried it once, it worked with my AN1x, but didn’t work on another users synth, so I gave up)
