Our instrument setup is already very flexible with the ability to apply effects. I often apply overdrive and distortion to the electric guitar, maybe with a lowpass to get great pedal type effects.
Now you will see an additional envelope button in the channel setup, allowing you to specify an override of enveloping for that channel (with other instances of the same instrument unaffected).
Other changes include a slight adjustment of channel levels - the range goes a bit higher now, with the high portion having an exponential boost effect .. works great for exaggerating bass channels.
In the background, we've also improved the tiny loop instruments.
