Additional Key Bindings!!

[chief]

Hey Jesse,

I started using an old USB keyboard as a footpedal to trigger SL. Works great! The only things that would be great to control w. Keybindings is:

1. Main in Mon (As in holding a key down to raise lower gain)
2. Main out (Same as above - it would be great to be able to do an overall fade out with a key)
3. Rate (Same as above - keybinding to controll variable levels)
4. Stretch (Same as above)

Thanks for reading!
