This bright box is the Psychotropia from Yellowcake!
A sample/hold filter with a glide knob option that that interacts
with a toggle switch for rising and falling wave forms. A lin/log toggle switch,
where the ‘lin’ is a hard edge square wave and the ‘lin’ position softens the edges of the square wave pattern. other features are hi/low eq cut, tap tempo to adjust rate
on the fly instead using the rate knob, a ‘res’ or resonance knob for feedback
oscillation and cv in and cv out.
