Euro Looping Gain Sequencer - under construction

clee Euro Looping Gain Sequencer full

The Looping Gain Sequencer is a sequencer based arbitrary wavefolder. The SEQ IN waveform is divided into 8 segments by voltage. The sequencer is addressed by one of those 8 segments. Each stage generates a CV which is available at SEQ OUT. and also controls a balanced modulator driving it from unity to inverted unity.

The grouping of 8 stages can be reduced in overall voltage and looped up to 8 times with the Loops control.

The sequencer controled balanced modulator modulates either the input at SEQ IN or the ALT IN. The amount of modulation is controlled by the SEQ LEVEL controls

Build notes

Some photos are of prototype builds: Panel is blue PCB, pot placement has changed sligntly, and no kludge wires are needed

Construction is a panel PCB and a component PCB

Both PCBs have circuitry

NOTES ON COMPONENT VALUES:

Capacitor C107 on the BOM and Schematic is 5n, 4.7n will work there

2 Resistors R127 and R130 are 38K, 39K will work fine there, or any value in between.

Current build is Version 1.0

Soldering LEDs
stuff the LEDs into the pcb without soldering. Attach the panel PCB to the panel and insert the LEDs into the holes so they’re seated. Then solder LEDs into place.
