Valley by After Later Audio is a combination of analog 5 stage Wavefolder and crossfader. For both audio inputs there is a control to adjust the volume ratio. The output of the crossfader leads to the Fun output, which outputs the unprocessed signal, and to the Wavefolder, which can be mixed with Fun/Fold from 0-100% to the output. The wavefolder itself is adjustable with Odd/Even and Order and sounds really good. There are control voltage inputs for the four parameters, two of them with their own attenuator.
The module is part of the ALA Coco system, a composite of up to three Cascades or Brooks oscillators and a Valley respectively Canyon module. These oscillators are connected to Valley in any way (e.g. 1x Cascades and 2x Brooks) on the back. This has the advantage that Valley can take control of keytracking for one or all oscillators and hardsync from oscillator 1 to 2 (and 3). In addition, the sine outputs of oscillators 1 and 2 are normalized to Valley's inputs; of course, other waveforms can be used by patching. The end result is a lush complex oscillator with West-Coast borrowings and finally the power of 2-3 analog tone generators plus wavefolders!
