Note: this project is almost ready to go, I’m waiting on some parts.

The previous version (without the switch) worked 100%, so I have good hopes

When this module test OK, I’ll create an Order thread!What is it?

A RGB Crossfade module with switchable normalisation routings.

The XFADE has one crossfade potmeter, 1x switch to change the normalisations, 2×3 input jacks,

3x CV jacks and 3x output jacks.

With the switch you can crossfade between two sets of full RGB signals with one knob or one CV source.

Other routings let you use the potmeter for crossfading separate channels while controlling one or more channels with CV sources.

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

It uses 3x LT1251 and 1x LM6172

Features:

2x 3 channel inputs

3x CV inputs

3x output jacks

1x Switch

1x Potmeter

the ordered part (sub miniature dpdt switch) is soldered and works as intended.

I’ll do some more tests , but it looks like this project is ready to launch
