Subphatty midi vs. El Capitan: close to giving up

Right… i love my moog but it is just refusing to play nice with my imac. Any advice much appreciated.

I have a 2016 imac, El Capitan 10.11.4, and all it will do with my moog is record audio. 10s of attempts to get it to accept midi messages in or out in any consistent way fail.

It seems to fail unpredictably and sometimes works for 20 mins at a time, but the most common symptons i have are hanging notes, which freeze the moog (knobs cease to work, lights flash randomly, instrument has to be shut down). The most consistent symptom is crazy midi in/out messages being received/transmitted by logic (see video here: https://www.youtube.com/watch?v=1A3Vew9SX4Q).

I’ve updated firmware in the moog, tried using USB and midi DIN cables, got fluent in changing midi settings in the moog (in particular trying to turn off all midi in or midi out, i.e. have the machine only either accepting or recieving midi), but no joy. I’ve also tried using both an external instrument plug in logic (on channel 3, with logic recognising subphatty as a midi output, and audio input on output 1) and an external midi plugin.

None of these attempts to isolate variables have given me any consistent results. In all cases i get at most a few minutes of working performance, before a note hangs, and the whole thing must be restarted, even then hardly ever getting working again during that session.

Really dispiriting to feel so close to having an amazing bit of kit work properly, but i cant afford to lose another two hours each sesh trying to make it work before giving up.

Any advice much appreciated!!!

Many thanks

Do you have LOCAL CONTROL turned off while the Sub Phatty is connected to your computer via MIDI?

Hey thank you - this is one setting i havent actually tried that much. But the moog should work with it on, no?

All i really want to do is play a line on the moog and have it record the midi, the play it back into the moog and play with filters etc…

Some more success yesterday though it still feels quite unstable.

I believe you can cause a MIDI feedback loop if you have LOCAL CONTROL enabled while having your synth hooked up to a DAW, which might explain the crazy behavior you’re seeing.
