dj crossfader/mixer

[maxcady]

ah good point about linear stuff. the quad slider module i linked to above that i'm considering is linear. dj mixers aren't linear, i imagine, thanks for pointing that out.

i still feel like i'm missing a piece of the puzzle, does anyone see a clever idea somewhere in here?

Sliders have two strengths - (1) it's easy to look at a bunch of sliders and SEE just where they're set, and (2) you can make changes on as many as you can reach with your fingers at the same time. They're not particularly good at fast up and down repeated movement - that's where rotary pots come into their own. A cross fade module is a hardwired device that can only do cross fades. The alternative is a gain module built around Analog Multipliers - depending on the inputs to the multipliers you can do gain, symmetry, cross fade, spiral, diamond spiral, and audio mod.

Hi! Building an Eurorack for laser control, really in need of a crossfader for X/Y.
Just two sources.

Did you build anything that works for you? I´d be super-interested. I don´t mind the patch cables

Hm, could this be an option?

Midwest Modular´s Blender:

• Overview

BLENDER is a four channel mixer and voltage controlled cross-fader. BLENDER simplies mixing audio and control voltages (CV) by incorporating a single control to blend two signals at a time - also known as a cross-fader.

Two manual cross-faders and a single voltage controlled master cross-fader are provided. This allows you to use BLENDER as two 2 channel mixers and a voltage controlled crossfader all at once seperately, or you can use the VC crossfader to blend between the two mixers.
Crossfade waveforms! Crossfade at audio rate, or crossfade CV for complex modulation!
Use BLENDER as a main mixer or as a dynamic control for creating complex control voltages and waveforms from your signal generators.
