My intuition about MacOS and midi loopback seems correct: By plugging in a hardware midi cable and routing all my midi through that between softwares on my computer, I no longer have instability when sending large ish amounts of notes from #supercollider to Bitwig. Why are computers so weird ?

@madskjeldgaard@sonomu.club Yup! I figured the same thing. I built a big Max patch that gives all my controllers lots of banks with virtual knobs. Problem is when I open Ableton Live and it decides to send status of all my 150-250 mappings INSTANTLY when I open the project Macos disables the virtual midi port. So now I have a usb -> midi interface -> midi female to female adapter -> same midi interface -> same usb. And it works perfectly...

@madskjeldgaard@sonomu.club MIDI rate issues have been in existence since its invention. Early versions of Waisvisz' The Hands could only interact with the Yamaha TX7 as that was the only synthesizer available at the time that could handle the amount of messages (which were sti within the MID specs. I imagine the issue you describe also has to do with the rate. Going through hardware, you have to respect the baudrate of MIDI, while in software, maybe it is not given. Receiving software may just react on whenever something comes in, expecting that the MIDI source respects a reasonable rate. And maybe the Virtual MIDI in MacOS is not ensuring that the source dies this?
