SCHLAPPI ENGINEERING BOUNDARY LAYER

Boundary Layer is a triple cycling slew acting as a swiss army knife of modulation functions. Each of the channels can act individually as a modulation oscillator, voltage controlled slew (including portamento), or AR/AD envelope (decay or release determined by choice of input). They are tied together by three inputs which affect all channels, as well as three outputs which select the MAX, MID, and MIN of all three voltages. CYCLE SWITCH Up position causes the channel to oscillate without external input. Equivalent to patching EOC to TRIG. INVERT SWITCH Inverts CV input. With no external CV input the envelope shape is changed between exponential and logarithmic. CV SELECT SWITCH Selects whether incoming CV applies to RISE, FALL, or BOTH. With no external CV input it determines whether the shape is applied to RISE, FALL, or BOTH. ALL TRIG, CV, SLEW Adds to each individual channel input for CV and SLEW and acts as a logic OR for TRIG. TRIG INPUTS Any rising edge of 0.6V will
