This is REALLY cool! Thanks for posting-- yet another great example for me to learn from... outstanding! Also getting this error. ^^ The preceding error dump is for ERROR: Message 'put' not understood. .. Very cool! If you don't set 'doneAction' to a value of '2' in your synth envelopes and you're using this SynthD.. *you'll be adding nodes AWESOME! This doesn't just sound great, but it's an awesome tut for beginners like myself. Thanks.. Very nice! And an awesome learning exercise for beginners like myself. Very nice!
