8 Patches with Boundary Layer by Schlappi Engineering

video upload by Stazma

"New Schlappi Engineering module alert!!!!
Welcome the Boudary Layer, a triple cycling slew acting as a powerhouse of modulation, audio mayhem, and obscure modular tricks in the tradition of Serge DUSG, the Make Noise Maths, our own Boundary, and others while also bringing a few new things to the table.

I'll show you some of my favorite patches with it, most can apply to other similar modules so it might interesting to anyone.

Have fun!"

Schlappi Engineering BOUNDARY LAYER / triple function generator / extensive playthrough

video upload by BRiES

"BOUNDARY LAYER by ‪@SCHLAPPIENGINEERING‬ is an apex triple function generator for eurorack. It has all the tricks up its sleeves and (as usual) is just a joy to work with due to it's well thought out interface and versatile feature set.
In this video I tried getting across how damn useful function generators are, how BOUNDARY LAYER works and how much fun it is to make patches with the module.
I hope you enjoy the video."

Boundary Layer is a triple cycling slew acting as a powerhouse of modulation, audio
mayhem, and obscure modular tricks. Each of the channels can act individually as:
-a modulation oscillator
-voltage controlled slew (including portamento)
-AR/AD envelope (decay or release determined by choice of input).

All three channels are tied together by three global inputs, as well as three outputs which select the MAX, MID, and MIN of all three voltages. Using different combinations at audio rate allows for patch programmable stereo drone synth capabilities.

Features

3 separate channels
3 global inputs
3 combined outputs MAX/MID/MIN
Oscillates from low LFO rate (a minute?) to audio rate (>10kHz with exponential feedback)
A CV input switchable between RISE/FALL/BOTH
Bound input for simultaneous control over cycling rate and amplitude
TRIG input for AD envelopes
SLEW input for AR envelopes and portamento or filtering
EOC ouput header switchable between EOR and EOF
16 HP
Skiff friendly 32mm depth (including cable)
current draw: +12V 170mA, -12V 100mA
