- Added 'active' mode.
- Usability improvements:
- Now uses an RGB LED with a different colour for each mode.
- Sine, sawtooth up/down, triangle modes are now combined into Waves mode and chosen by tapping the modifier button.
- Disabled some randomiser modes - the code is still there so they can be enabled again if wanted.
I also added a power jack so it can be powered via a normal 9V pedal power supply.
