Just some after thoughts on this old topic, and how the bounce in place function for external hardware instruments does not work full stop...
I've been demoing Ableton Live, and using Lives external instrument plug-in for use with hardware synths. I then chose the "freeze" function from the menu, and Live then detected i was using hardware synths, and the render to audio file was performed in real time........ Live = clever !!!
Why can Live get it right, and Logic can't.... ?
Hoping this does get implemented in the future.
