WMD revises Skorpion wavefolder prototype to revision 1.10 after mid/side rework

WMD has moved its Skorpion Waveform Reanimator to prototype revision 1.10 after reworking the module's mid/side matrix and stereoizing circuitry, William Mathewson reports. The revision 1.08 unit shown at Superbooth required the redesign, and the next prototype round is expected in September.
The Skorpion is an 8-stage analog wavefolder built around a slider interface. WMD describes it as an "8-stage analog wavefolder that allows you to precisely mangle simple waveforms into complex shapes with a fun, hands on slider interface"1. FOLD sets input gain so the signal hits each of eight thresholds, reversing the output at each point; SLOPE sets the baseline rate of the output; SHIFT applies vertical shift; and SHAPE is a feedback control with eight available sources1. OUTPUT crossfades between dry, wet and a stereo wide signal generated by a mid-side filter matrix, and the DC/FILTERs control switches the low-pass and high-pass filtering in that matrix1.
Modulation comes from 13 internal sources: a macro envelope, eight threshold LFOs and four CV modulators normalled to the FOLD, SLOPE, SHIFT and SHAPE attenuverters1. WMD lists 20HP width, 38mm depth, +200mA and -160mA power draw, an LFO range of 0.0016Hz to 6Hz, envelope times of 0.05s to 600s and a 240Hz high-pass/low-pass cutoff point1.
Mathewson wrote that the redesign was his own doing:
"I made too many edits/mistakes in the mid/side matrix and stereoizing circuitry to go straight to production"
He also wrote that "with a few minor modifications to values and circuitry, the Skorpion is DONE, finally!"1. Preorders are closed, and WMD describes the module as a single limited production run shipping September to October1. Mathewson attributed a panel delay to the manufacturer's machine going down and requiring replacement, and wrote that panels had shipped to the US1.
