Dual Portamento / Glide Buffer
Get all wibbly-wobbly with your control voltages.
This is a bog-standard dual glide buffer - the old favourite of a resistor and capacitor combo the blur the edges of your square(ish) waves into slidey wobbliness. This module consists of a pair of glide buffers, both of which are capable of working at audio rates as well as more pedestrian LFO/sequencer type speeds. The inputs are DC coupled so they're good for audio(!) or control voltages. Run a sequencer output through it to get all slidey.
Glide time will depend on the potentiometer setting - by default, the 'glide' capacitor is 1uF so with a maximum resistance of 1M you'll get a maximum glide time of around a second. Obviously, lower resistances mean shorter glides.
The fully assembled module includes a laser-cut, engraved panel made from 3mm perspex and supplied with knobs where appropriate - the perspex is translucent grey with a spray coat of dark enamel paint on the reverse side to emphasise the engraving.
