Auh yes, you have put your finger on one of the problems with the current git repository. Once a built-in synth is loaded there is no current way to switch to another built-in synth. Upon loading a module there's no way to switch to another built-in synth. If changing synths is necessary I would recommend builting them as modules which can be loaded and unloaded at will. We are working on bringing back the ability to change synths but it is not complete yet. I will turn my attention to that as soon as I have the cut and paste issue fixed and ready for testing. It's current status is that I can lock a machine with a single mark keystroke everytime ten out of ten tries! 'grin' Anyone want to test it?
