I’m just beginning to get out of the box and dip my toes into hardware, starting with the 0-Coast. I read that the output on Apple’s lightning to 3.5mm headphone adapter is DC-coupled, so I’m trying to use it to send CV signals from my iPhone over a eurorack patch cable into the 0-Coast. I believe the outputs on the headphone dongle are relatively low compared to typical eurorack level — about +/- 0.5V. I’ve been experimenting with drambo but so far haven’t found a working combination of in-app module routing, app settings, iOS system settings, hardware cables and adapters etc that results in audible CV modulation in my 0-coast patch. I’ve mostly been trying to patch the cable from my headphone dongle into the 1V/oct pitch input on the 0-coast, thinking that +/1 0.5V would be enough to hear a full octave of pitch modulation. But it seems like nothing I do in the app is having any effect. Has anyone here been able to get better results while using the Apple lightning to 3.5mm headphone adapter (or the Apple USB-C to 3.5mm headphone adapter)?
If I’m able to get this working, my next step would be to try to find a way to amplify the signal to eurorack level. I know there are plenty of eurorack modules for converting between line level and modular level signals. But it seems like overkill to buy a whole modular case and power supply just to be able to use one of those modules with my semi-modular. I’m looking for something more like a desktop solution or an adapter that isn’t a eurorack module itself.
