This is a digital vco with on board wave table and sub oscillator outputs that are audible.

The Tune Knob Parameter is Quantized. As you turn the knob it locks to musical chromatic scale.

This is an analog vco based on the Bergfotron Advanced VCO. It has heavy modification compared to other buchla vco's. It will track much better than other modules because this is using a VCA based tracking system instead of the matched transistor system. The 'Lock' switch allows for setting up your favorite reference Frequency. For example you can set it up on Zero Volts equals low Note 'C'.

You use this as a sound source.
You use this as a precision LFO.
You get a bonus analog sample and hold.

There are two possible sound source outputs:
-Wave Out. This has 8 possible wave shapes: Triangle, Saw, Double Saw, Pulse Width, Sine, Ramp, Even Harmonics, and Double Pusle wave. All of this is selected by push button. The selector circuit is using a Precision DG412 IC chip, so there is no bleeding. There is of coarse CV input for the selector (by Triggering).
All 8 waves are roughly -5 / +5.

-(Positive) Static Square Wave Out. This is a great clock source, it is also a great sync source for other products.

The analog sample and hold is using the internal VCO as the 'clock'. You simply patch a sound source on the 'input' and use the output to monitor the result. The (red knob) Tune knob above is used to control the S&H rate.

This product is the evolution of the 'Transistor Pyramid Core' saga.
