Our 4093 Chaos NAND Synth in Eurorack form! The 4093 Chaos NAND Synth is a super-modifiable noise generator that will knock your socks off with its sonic potential: low pulsing drones, random robotic chaos, and high-pitched laser sounds!A great project to begin your explorations into the world of DI..

Get ready for the bright lights of the colosseum! We've taken our rock-solid RAT clone, squeezed it into a Eurorack module and added CV control over Gain. The 308 will take your playing to new heights with tremolo and other distortion modulation techniques. Features:3 controls - Tone, Filt..

Synthrotek is proud to offer a line of 1U Eurorack powered modules for your modular synthesizer system. 20 and 24HP sized modules means that you can completely fill a 84 or 104 HP row with no extra modules or blank panels needed. Synthrotek’s waterproof cases come with a 1U row designed for utility..

Module A-138m is a  4 x 4 matrix mixer with switches for unipolar/bipolar mode for each column. Unipolar means that the controls work as attenuators. Bipolar means that the controls work as polarizers. In this mode the amplification is zero in the middle position of the corresponding control. T..

Module A-138d can be used in two different ways:as a crossfader module within the A-100as an insert module for external effect units (e.g. guitar stomp boxes) with dry/wet controlIf the module is used as a crossfader within the A-100 the two audio signals are connected to the sockets In 1 ..

Module A-138c is a four channel mixer, that allows to add or to subtract four incoming voltages to the output signal. In the middle position of the corresponding control the amplification is zero. Turning the knob counterclockwise the signal is subtracted from the output sum with increasing amount. ..

Module A-138 is a four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator, and there's a master attenuator, so that the mixer can be used at the end of the audio chain - ie. it can be used to interface directly with an external m..

Module A-137-2 is another version of a wave multiplier. In contrast to the A-137-1 Wavemultiplier I the A-137-2 generates four phase-shifted copies of a VCO signal applied to the audio input. The four shifted signals are added to the original signal to obtain a fat sound similar to five independent ..

A-137 is a voltage controlled Wave Multiplier. The basic idea of a wave multiplier is to multiply the waveform of an incoming signal (e.g. triangle/saw/sine from a VCO) within one period of the waveform. This leads to additional harmonics of the incoming signal. The period and consequently the pitch..

Module A-135 is a distortion and waveshaping module with extensive control possibilities. The incoming audio or cv signal is internally divided into 3 sections:positive component of the signal with adjustable clipping level (even externally via jack socket) and positive or negative amplification (+/..
