Notes: The EVEN VCO is a voltage-controlled oscillator that offers stability and high precision tuning over 10 octaves. A redesigned temperature compensation circuit maintains the oscillator stable against voltage and temperature drops.

Specifications:

Current needs: +12V: 36mA, -12V: 26mA
Width: 8 HP
Depth: 22mm, (28mm DIY) including power connector
Aluminium, heat-treated front panel.
Designed, kits prepared and completed modules assembled in Barcelona.

Notes: Performance-focussed crossfader module designed to simplify the process of morphing CV and audio signals. Quad channel design with lots of creative potential.

Supplier's Notes:
Morphader is a performative tool designed to make multichannel CV/Audio crossfade easy and comfortable. Fading from one quad CV/audio scene to another. The core of the module has four CV controlled crossfaders, each with their individual control and a master fader to control them all. The module mixes the four crossfades at its fourth output, thanks to a clever normalization scheme. Each of them can be easily removed from the mix by plugging a cable at its own output.

Main Features:

CV Controlled four channel crossfader.
Attenuators per input.
Normalized voltages to every input, allowing cv levels morphing.
Fader control to crossfade all channels at the same time.
Cv or Audio switch per channel to change resposne curve.
Leds per channel for signal level monitoring.

Notes: Space-conscious lowpass filter and volume processor.

A combination of VCF + VCA + Mixer that lets you mix three different sound sources, and shape their tone, and levels in a breeze.

The Pony Filter is built around the SSI2144 FATKEYS Chip. Has the elegant sound of the classic transistor filter without the associated distortions, due to Dave Rossum's "improved ladder" topology.

Notes: The Sampling Modulator is a multi-function module that lies somewhere between a VCO, a Sample & Hold, and an 8 step trigger sequencer.

Sequencer Clocked Sample & Hold

In this mode it acts like a regular Sample and Hold (S&H) but since it is "sequencer clocked", it is capable of much more interesting patterns than the usual S&H melodies.

The CLOCK input can work in two ways: 1. As a typical clock 2. In "positive going hard sync" mode allowing you to create shuffling and polyrythmic effects.

The HOLD input can be used to keep certain notes playing.

Analog Down-Sampling Effect

In this mode (with the clock running at audio rates) you can go from nasty and harsh sampling rate reduction to an almost clean signal. (The clock run up to 25Khz without external CV and up to 200Khz with CV on the input).

Sampling Modulator/Shaper

Thanks to the V/Oct clock, by feeding a simple waveshape such as a sine wave to IN, and pitch CV to the VCO as well as to the Sampling Modulator CV input, their related frequencies and aliasing caused by the sampling rate reduction are capable of creating clangorous metallic sounds, 8 bit textures and much more.

The game becomes much more interesting when you try to destroy the wave by flipping on and off the switches of the sequencer (which at times can make it sound like three VCOs running in unison).

To understand how the Sampling Modulator works, keep in mind that we are working with a temperature compensated ramp core VCO with more than 4 octaves of tracking. This allows the timbre to stay the same while you move through the scale as the internal and external VCOs are synced in a fashion similar to "frequency related sampling rate modulation"

Unusual V/oct VCO You can use the trigger outputs as a pulse VCO. Flipping the switches on and off the switches can offer a lot of interesting timbral changes.
