Does anyone have a really simple example of feedcack FM i could have a look at? Just a simple cycle feeding back onto itself should suffice, just not sure about exactly how to implement this myself. I'm guessing you could use tapin~ and tapout~, but i'm not sure how to scale the values from tapout~ and how to feed it backing into the signal chain.

This isn't as simple as it seems... You can feedback with 

tapin~/tapout~, but this will create a signal vector of delay. Thus it 

would still sort of work, but with different results than a DX synth for 

example. It would be necessary to create an external, either in c or

maybe in Java with mxj~...

just multiply the signal with a float value less than 1. to scale it.

nice feedback oscillator by volker bohm here:
