Utility Eurorack module with 3 crossfaders, 3 channel mixer as well as true analog white noise output based on Johnson–Nyquist transistor noise scheme. Crossfaders can be used for VCO wave mixing, precision CV/audio attenuation, converting bipolar CV or audio to 0 to 5V, stereo panning or as dry/wet mixers in effect signal chain. Crossfaders are optimized for modern 0Ω impedance.

Upgraded version 2.1 features improved mixer, precision voltage regulator routed to the 3 crossfaders, when nothing is patched to crossfader inputs they can be used as 0 to 5V attenuators, mixer channel 1 routed to output to overdrive the mixer for heavy distortion when nothing is patched to the input 1. Includes 10 to 16 pin power cable.

3 channel mixer in the module is designed to perform analog signal summing and subtraction with soft clipping. Subtraction allows converting low pass filters to high pass, balanced signal inputs, complex wave mixing etc. Copy of mixer output signal can be fed to one of its inputs creating feedback based overdrive, together with soft clipping it can produce heavy analog distortion. Other modules can be placed in the feedback loop creating different sound effects.

On the front module offers two leds, one indicating that signal sum had reached 5 volts, second one turns on when signal is overdriven. All potentiometers are precision Alpha variety, module is made with high quality electronic components and audio grade OpAmps, features rubber knobs with soft touch for easy grip and tactile feedback.

When combined with our envelope follower and our quad VCA module can be used to create analog compressor where one of the crossfaders works as voltage attenuator to control the threshold CV and another mixes input with feedback from compressor output:

Paired with our gate to pulse converter, envelope follower and VCA module can be used to create analog hihat from gate input:

I use these handy crossfaders a lot to mix between different modulation sources as well as dry and ring modulated VCO outputs:
