RGB Crossfade module with interesting routings

This module has three crossfade VCAs that can be controlled by one source to achieve RGB fades and wipes.

The VCAs can also be controlled separately as three single crossfaders (fade between 2 sources) and
as three single VCAs (fade between a source and no source, a black image)

The XFADE has 1x crossfade potmeter, 1x switch to change the normalisations.
2×3 input jacks, 3x CV jacks and 3x output jacks.

This way you can crossfade between two sets of full RGB signals with one knob or one CV source.

Other settings let you use the potmeter for crossfading separate channels while controlling one or
more channels with CV sources and disabling the potmeter alltogether, to prevent accidental touching.

The CV voltage range can be set from 0-1volt up to 0-5volt with a trimpot on the backside.
