PS. I'm no SuperCollider expert.... but I did just try running your code with a couple of tweaks and it has opened 16 channels for me and Tidal is routing audio to different ones... so maybe try this with your setup and let me know how you get on
(
s.options.numBuffers = 1024 * 256;
s.options.memSize = 8192 * 16;
s.options.maxNodes = 1024 * 32;
s.options.numOutputBusChannels = 16;s.waitForBoot{
~dirt = SuperDirt(2,s);
~dirt.loadSoundFiles;
~dirt.start(57120, [0, 2, 4, 6, 8, 10, 12, 14]);
s.latency = 0.0;
};
