The MIX | Crossfader is part of Umbrella's "Cyclic Oscillations" bundle which consists of 6 modules aimed at CV processing. The bundle has 4 low frequency oscillators and two cv-mixers.
The MIX-Crossfader can be used to crossfade or mix 4 seperate input channels. Making it possible to add variation in CV modulation in four different ways.
The controls and their functions:
In 1 to In 4: There are four jacks for the separate input channels.
Fader knob: This knob controls the fade between the four in's. At the position 1, 2, 3 and 4 the knob let's the unprocessed signal of the inputs through. Between these positions the in's are faded linearly. With the knob set to about 9PM, for instance, you will get 50% of 1 and 50% of 2.
CV attenuator: This knob controls the amount of CV passed through to the fader knob.
CV in: The CV-in is the input jack, to attenuate the fader knob. Making it possible to shift through the different values of the knob.
1/2 out: This output only passes the faded input of channels 1 and 2 through. Between position 2 and 3, the signal of input 2 decreases from 100% to 0%.
3/4 out: Same as 1/2 out but for input 3 and 4.
AVG out: This jack passes the average signals from 1 to 4 through. See this jack as a combiner of the average values of the four input channels together that can be processed as a pair. The AVG can also be patched back to a input. So if in 1, 2 and 3 are fed by a external source, the AVG can be fed to In 4. Making it possible to fade between 1, 2, 3 and 1,2,3 as a new average source.
ALL out: The all out is the output you would expect from the cross-fader. This jack outputs the signal 1, 2, 3 and 4 processed by the fader knob.
