thru&hold sample&hold bidirectional switch
This module has 10 circuits: 4 thru&hold, 4 sample&hold and two bidirectional switches.
The thru&H and S&H all work off the same CV signals (or noise or whatever else applied to the input) but each stage is independently gate controlled.
The bidirectional switches are, of course, inspired by the early Serge modules of the same name and have the same functionality. Either feed an input signal and use a gate to choose whether the input goes to output A or B, or feed two input signals into A and B, then use a gate to decide which gets fed to the output. This design differs from the Serge (which uses 4007 CMOS) as it uses DG411 analogue switches and can pass any signal between +/-12V. It can also operate at audio frequencies so some fun can be had using 3 audio signals to switch between each other.

Korg 800DV CV/gate mod PCBs - $20 including shipping
These PCBs are for Korg 800dv synths. Each has two CV channels and two gate channels, based on the schematics from e-lab. You only need one.

The Plan!
Have pretty much settled on the modules and designs for 6 panels. Nearly all the PCBs are here, panel designs are not all finalised, so there may be some changes. Feel free to send me suggestions. I have a few proto-type modules in mind that may get into Panel 5 if they work out.
So
Panel 1 - bindubba 1 & 3 sequencers, multiples (banana to minijack connectors)
Panel 2 - PMS VCO, PMS VCO, dual DC mixers, LDR VCA/mixer, dual LFO, utility EG
Panel 3 - 5 stage Resonator, dual triple channel VCAs, double Jerkoff Chaos, EoE VCF (transistor ladder), ARP/Electronotes style 2 pole VCF, Divine CMOS (sub-oscillator, harmonic divider, harmonic ring-modulator, pattern generator, all kinds of tricks!)
Panel 4 - CMOSC (6 simple CMOS drone oscillators with gate selectable frequency control and sync function), 4 stage Thru & Hold, 4 stage Sample & Hold (these each have CV inputs and 4 individual gate controlled outputs), Four Squared Logic, The Great Divide, 8-bit Cipher, dual bi-directional switches.
Panel 5 - two Envelope Generators (based on Korg 3100 designs but modded for CV control of Attack/Decay, extra outputs and retriggerable), dual DC mixers, four Utility VCOs (these are 1V/oct and range from approx 0.1Hz to 8kHz so can be used as LFOs too), twin-T VCF with voltage controlled resonance, VC Wave Clipper, dual analogue Neuron.
Panel 6 - PT2399 based delay, Ramp generator, dual Utility VCOs, Veena (drone module based on Indian musical instruments), Six channel Mixer/Panner with headphone amp and multiple outputs (banana and 1/4 inch), Six Random Noise sources (pink, white, slow random, etc), Six Passive filters (Vibes, Vox, Brass, Funk, Harp, Gurgle - to use with extra outputs from Veena), The Bigot (CV controlled signal splitter), analogue And, Analogue Or, Controller (module for adding proximity or ribbon controller)
