Thanks. Looks like I have to abandon my plan, then. Out of interest, what is it that makes it not possible to use a simple custom TRS -> DIN cable?

Hi all, apologies for the partial hijack of the thread, but I have a question that is somewhat related as I would like to make up a cable that is TRS MIDI out to DIN MIDI in. What I'm trying to do is to connect up guitar fx pedals to be controlled via MIDI from a Morningstar MC6. The hardware I am using after that, is a Meris I/O, Meris Enzo, Strymon Timeline, and Source Audio Ventris. For space reasons on my pedalboard I'd like to connect each pedal to the Meris I/O via the TRS connections. This is simple for the Enzo as it's a TRS MIDI IN. For the Timeline and Ventris, I need to make up a custom cable as the MIDI in on those is DIN MIDI. In my simple understanding, as the Enzo uses a standard TRS to TRS cable it should be possible to make up a cable that's TRS to DIN, provided I know which connections to make at the DIN end. I do know that the Meris pedals receive MIDI data on the tip (so as it's standard TRS they're also sending on that at the Meris I/O) but don't know how that relates to the DIN MIDI in pin arrangement. Does anyone know how to decode this? Is it not as simple as I think it is? I've been told by Meris that it's not straightforward as I would need opto-isolator electronics to make it compliant with the MIDI spec. and reliable. I don't really understand why that's necessary for TRS to DIN, but not TRS to TRS. There seem to be some knowledgeable people on this thread, so any information is much appreciated! Thanks, Phil
