I am trying to create an FM based multi oscillator synth and I want to be able to glide between states. Using another thread on Interpolating presets I have created a way to glide between states that work perfectly for simple patches. However for this patch it just crashes it, can anyone see what I’m doing wrong? The patch is a bit of a mess but you should be able to see what I’m going for. I have attached in Max and Max for Live formats.
