Topogram is a sequential soft key generator capable of splitting live video and patterns into discrete bands for colorization and control. Edge transitions feature voltage controlled gain for creating hard edges or smooth gradients. Upper and lower thresholds for the keying range may be voltage controlled separately.

Topogram takes simple inputs and slices them up. Six non overlapping regions can be patched out for 6 band colorizer patterns, along with another 8 outputs which group and span multiple ranges.
Driven with LFOs and low frequency envelopes, Topogram becomes a frequency independent sub-event generator for animation control of your patch.
Topogram features elevated technical and performance specifications, and is the result of years of research and testing of discrete analogue video circuitry. The signal path is fully active, and CV attenuverters have a deadband range in the center. The circuit is entirely analogue.
