VCO pics

These are pics of the VCO in the VCO panel. the PCB is available as a DIY project, so these pics are to help any builders.

cellF panel #2 - action

This is the 2nd panel for the cellF neuron controlled synth. It contains:

• 7 stage divider (from /2 to /128) with a staircase output
• chained logic module with related but individual logic circuits, the outputs are connected via a resistor ladder to give a SOU266 style random stepped CV...which has voltage controlled slew so can be a random smooth CV if you prefer
• QUO/LPF an effective low pass filter, quadrature oscillator with high/low range so can be used as a VCO or LFO
• VCO: tri-core with tri & square outputs
• Chopper....chop slewy!
• VCA
•  Delay No More: updated version with vactrol based CV 'control' of both delay stages and individual signal inputs and outputs for each stage. It maintains the same functionality as the original PCB version but can also be tamed and actually used as a delay (just)
• Vactrol PiLL: a PLL based audio/noise source, it has no knobs
• DP Filter: same as the PCB version
• Sloth: 15 minutes per cycle chaos module
• FF Chaos:  a gate/CV controlled chaos module that produces two chaotic CVs and 2 gates of chaotically varying widths.
• Offset Mix: CV and audio mixer, pots 3 & 4 can be used to add negative or positive offset voltages if the inputs are unused.

Chopper

Chopper - expected this week. This is an analogue switch on steroids. The concept came from a 60s chopper modulator circuit. It can be used as a VCO, a VCF, a waveshaper, ring modulator, analogue switch, LFO and VC gate generator....probably more. It can switch between two input signals with the actual input signals deciding when to switch, or the change can be VC or manually controlled. There is also a bi-directional switch as a separate circuit on the same PCB. this is functionally the same as the early Serge bi-di Router but uses a DG411 analogue switch rather than a 4007 to do the work.

FF chaos

FF Chaos (flip-flop) - This is another chaos module but designed to supply a variety of gates and triggers. It is self running but can be synced with the gate/trigger input. There is also a CV input which shifts the output between periodic and chaotic behaviour. There are two CV outputs, one trigger output and three gate outputs which supply different and varying gates that can be delivered in bursts......this thing is simply nuts.

The most common build error with these is people soldering the passives on the bottom of the PCB onto the wrong pads. Please use the above picture to check the passives are installed correctly. Also some PCB versions need a couple of mods, check the Build Guide to see if your version need these.
