Hi! Don’t know - bug this or feature but noticed the next thing:
using extenal synth with Renoise (Yamaha MXS), boucing it via “render song to disk” to get a wav file with composed sequence.
When rendering is done and I return back to main window the external synth sound get missed. I figured what Line Input device become deactivated after “render song do disk” procedure is complete, although device’s “enable” checkbox is checked. Solution of that issue is to switch checkbox off and on again.
Using Renoise 64 bit 3.0.0 under Mac OS X 10.9.4 .
