Output Level - 0 - 10V

Original 909 Attack control

Extended 909 Decay control for more umphhh

New controls for the oscillator tuning:

Attack tune

Decay Tune - these two will have an effect on each other which makes it really cool

Global Oscillator Tune control - this sets an offset for the oscillator, sets the starting frequency for the envelope

VC-Tune with attenuator (can go over a wide range)

Overload knob - might not be everyone's cup of tea, what it does is overload the sine shapers which adds harmonics and some extra punch, it's an aggressive effect.

VC - Overload - Can be CV or even audio

Accent in - can be with a pulse or CV 0 - 5V
