Frequency Central - CEMvelope

ADSR Sequencial Pro-One

CEMvelope is based on the legendary ADSR section of the Sequential Circuits Pro-One monosynth, with minor adaptations to integrate it into Euro format. Smooth and snappy!
It has a gate input as well as a trigger input, the trigger input works in conjunction with the gate input for multiple triggering from a suitable controller device.

CEMvelope has at it’s heart a CEM3310 or AS3310. Here is a Video about it.

Technical Information

8mA +12V / 11mA -12V

Including white knobs


This is a Do-It-Yourself kit, not an assembled module.

Frequency Central - Meth Amp

Big Muff Distortion

Meth Amp is based around the fuzz core of the EH Big Muff pedal.
Lovely fuzz and distortion based on the classic Big Muff pedal! It’ll do wooly warm fuzz, subtle tone shaping with a soft saturation/colour, feedback madness and work as a great output VCA (LPG style tones possibly too). The clipping diodes have been replaced by red LEDs to take account of the change in power supply from 9V in the original Big Muff to +/-12V in Meth Amp.
To the fuzz core has been added a bunch of OTAs, each controlling a different aspect of audio processing: gain, regen (a new feature – not present in Big Muff), tone and volume. Thereby, each feature is fully voltage controllable.
Additionally, there is a separate x100 preamp which can be used to boost external audio for further processing by Meth Amp. Here is a Video about it.

Frequency Central - Raging Bull 3.0

Voltage controlled Filter Moog Taurus
Raging Bull is based on the legendary Moog Taurus Mk I VCF and VCA. It has a lovely, thick Moog-like quality, which is further enhanced by the drive you can get out of its VCA at higher settings.
A big part of the sound of the Taurus was the way in which the VCF interfaced with the VCA, so on Raging Bull the VCA is always in the audio path. A toggle switch allows you to select ‘always open’ or CV control of the VCA from CV input 3.
By sending an ADSR into CV3, the signal will go to the VCA CV input unattenuated and the VCF CV input via the attenuator 2. By sending a gate into CV3, and setting the attenuator to zero, the VCA can be gated while the gate has no affect on the VCF.

Frequency Central - State 700 VCF

Variable Filter Roland style

Based on the Roland System 700 state variable filter module. Lowpass, bandpass and highpass outputs. A big part of the sound of the State 700 is the way in which resonance is reduced as the audio inputs are driven harder. It won’t self oscillate with a hot audio input, throttle back a little and you’ll get squelchy ear bleeding resonances!

Here is a Video about it.
