I have been using the modsynth, and a few instances. It will run fine and play for multiple hours, as long as I don’t change spawn parameters on the emitters that are controlling the note on via spawn or collision. As soon as I change spawn parameters, it stops functioning until a restart. Am posting a proof of concept in a separate thread.
Could totally be a resource issue, and in the future I’ll use the synth component directly and not the modsynth, just wanted to get my hands dirty quickly and try some things out.
