WFv2: Lockhart wavefolder (2HP)

(this recording was made with the 'old' version of the module -the only difference between this and the new one is that you can now fade between the folded signal and the square-wave pulse-train for a more varied sound

An updated version of the Lockhart wavefolder - the majority of the assembly is now done by the fabricators, meaning that I can use smaller, and cheaper, components (0603, rather than 0805) whilst still allowing a degree of repairability.

As one of my 'high turnover' modules (ie. I sell a lot of 'em) the bulk of the assembly is now handled by the board fabricators with the final assembly and testing taking place 'in house'. There are several advantages to this: first, I can take advantage of the fact that parts from the fabricator are very cheap (economies of scale etc.) and second, I spend far less time faffing around with surface-mount components, leaving me to do final fitting of any through-hole parts plus any testing.

Functionally, the circuit is the same as its predecessor in that it produces a folded version of the input signal as well as an asymmetric pulse train which is generated whenever the folded waveform crosses zero - where it differs is that instead of separate outputs for each, there's a single output and the folded and pulsed signals can be mixed to generate a broader sonic palette.

Works best with triangle or sine-based inputs, and is a great way to thicken up a sound - you may get some interesting noises out using a sawtooth/ramp waveform but square waves won't really do an awful lot. Works really well with a bandpass filter.

The input level and bias controls are still there, but there's now the mix pot and the single output. However, despite all these differences it still manages to fit in 2HP.

2HP wide - includes mounting hardware and power cable.
