Infinitely Maybe, as random as a lager sandwich

Infinitely Maybe is a full featured randomness module, with a number of sources of randomness:

  • White noise
  • Pink noise
  • Sample and hold circuit
  • Random gates circuit

An onboard CV mixer allows you to mix two different sources into the sample and hold circuit. White noise is normalised to CV input 1, Pink noise is normalised to CV input 2

Infinitely Maybe has an onboard clock for triggering the sample and hold circuit. This may be overridden with an external clock if required via the clock in socket.

There is a built in LAG circuit, which enables the S/H OUT to slide between voltages at a predetermined rate. This function can be remotely controlled via the LAG IN

Finally, a random gates output is derived from the S/H Out. With the MAYBE knob at 0 a constant gate is available. The further you turn the MAYBE knob towards 10, the less likelihood of a gate is.

Mix, amplify, clip, invert…..Volts Platz has it all.

A year or so ago I stopped selling System X CV Mixer. People keep asking for it, so I added a few features, changed its name, and now it’s back!

Volts Platz has 4 inputs with attenuators. Input 3 is normalled to +ve for positive offsets (up to +8V), input 4 is normalled to -ve for negative offsets (down to -8V)

The first opamp stage now includes a switch to select x1, x2 or x10 amplification. You can take a direct (inverted) output from this stage.

The second opamp features switchable clipping diodes (LEDs) which clip anything above/below +/-5V. So ‘normal’ Euro signals go through unaffected. Flick the amplification switch and things gets dirty.

Patch a post-VCF signal into input 1. You can then use a combination of offsets at inputs 3 and 4, and CV into input 2 to explore modulated symmetric and asymmetric clipping.

Scale, offset, amplify, clip. Or just use it as a 4 input mixer.

State 700 gets an upgrade….say hi to State 700 MK2

State 700 has always been a popular VCF here at FC. We’ve given it a bit of an upgrade and a lovely facelift. It’s output is gainier, it’s panel layout is more ergonomic, and it’s now only 35mm deep in your rack.

Klang Stadt has landed…..

Klang Stadt is the latest FC iteration of Electric Druid’s VCDO digital wavetable oscillator. It features a number of advantages over our previous Waverider design:

• improved PWM filtering
• addition of Sub Two output
• addition of Klang output
• addition of Xmod feature
• onboard LFO for riding the waves

If the Klang output worries you, you can cover it over with a bit of masking tape. That’s what I’ve done with mine.

Klang Stadt assembled module: £210 GBP

Everyone needs MORE VCAs!

Hey everyone! How are you? My guess is that you need MORE VCAs!

MORE VCAs is a compact 4HP width dual VCA module based upon similar circuits found in vintage ARP synthesisers. Use it where rack space is at a premium, and when you need that warm analogue goodness. Each channel features an audio input and output, together with a CV input. An Initial Gain knob is also provided for fine adjustment,This can be used like a Hold switch, if you want to create a drone sound. The audio inputs can be pushed hard to create a thick and natural overdrive. This can be used for a wide range of sound design possibilities.

I’ve engineered out the rare parts and the need for matched transistors for the CV input section by using a Roland style circuit there instead, no change to the vibe though! The audio path remains pure ARP, with one exception. Built stock from the schematic, the resonance would clip like a motherfucker above 3 o’clock, in a way which is neither musical or desirable. I’ve come across a couple of other versions which have this ‘don’t turn it up past 8’ trait. I’ve engineered that out – a single resistor values change. Now resonance is usable and musical over the entire range. As we’re bringing part of a hardwired synth to modular, it’s also necessary to buffer the output. I’ve used an inverting buffer, which also adds a bit of gain to bring it up to modular levels. A nice side effect of the inverting buffer is that if you mix the input signal with the filter output, and find the sweet spot, you can do highpass filtering too!

What a cutie xxxxx

Aw, little baby! Hi there Process 26! Looks like you’re an ARP 2600 inspired voltage processor.

The upper voltage processor features four inputs which are mixed and inverted at the output. Inputs 2 and 4 have their own attenuator. Input 2 is normalised to a positive fixed voltage source, which may be attenuated, and appears inverted at the output, useful for applying negative offsets.

The lower voltage processor features two inputs which are mixed and inverted at the output. Input 2 has it’s own attenuator. Input 2 is normalised to a negative fixed voltage, which may be attenuated, and appears inverted at the output, useful for applying positive offsets.

Process 26 PCB/panel: £20 GBP
