This free preset is available on the Fractal Audio forums at https://forum.fractalaudio.com/threads/free-archon-all-in-one-preset.165928/
It is based on my Amp Packs :
I just released an Amp Pack bundle for the FM3 too :
This preset uses 2 expression pedals :
FC1 Pedal 1 is used for wha (scenes 1-4) or morphing tremolo (middle of the pedal course) and/or rotary (heel down)
FC1 pedal 2 is used for volume
In scenes 1 to 4, the gain level of the amp is set in Controllers/Scene control 1-4, you can adjust it there. With this method, going from rhythm (scene 1) to crunch (scene 2) or lead 1/lead 2 (scenes 3-4) is completely gapless.
