4-stage Analog Shift Register (ASR) module with built-in quantizer & digital noise generator - 14HP
Notes: The E102 is a 4-tap delay for control voltages (a digital implementation of the Serge ASR - Analog Shift Register). There is also a digital noise generator with 8 different types of noise spectra. With no CV patched into the INPUT jack, the digital noise is sampled. Each clock pulse (internally set by RATE or patched into CLOCK IN) samples the INPUT and stores it as a 14-bit value. Successive clocks then shift the sampled voltage to the next output. The sampled voltage is shifted in the delay line as OUT1 > OUT2 > OUT3 > OUT4. A quad 14-bit DAC drives the outputs with an accuracy of <1mv.

A unique addition to the traditional ASR is the voltage-controlled DELAY. Selectable in 3 ranges, this adds delay stages in-between each output. For example, if DELAY was 2, then it would take 6 additional clocks for the OUT1 to "travel" down the delay line to appear at OUT4. The INPUT is sampled once for each clock, no matter what the DELAY is. The outputs can be quantized to whole-note steps.

The most common use of the E102 is having each OUT drive a VCO. If you have a step sequencer, then use the sequencer's clock into CLOCK IN and the sequencer's CV out to INPUT. The 4 OUTs will then generate a musical canon (like "Row Row Row Your Boat") when driving 4 VCOs. Each VCO will play the same note as the prior clocked output. This is of course assuming DELAY = 1. DELAY is not the same as a 'clock divider': when DELAY is not 1 (say it is 12), then every sample clock, the INPUT is fed into the delay. In this case there are 12 clock-delay stages between each out. If 0.25V was sampled and appears at OUT1, then 12 clocks later that same 0.25V appears at OUT2. There is no delay from INPUT to OUT1. The delays are OUT1 to OUT2, OUT2 to OUT3, and OUT3 to OUT4. OUT1 is a 'traditional' sample/hold.

Dual wavetable LFO with unique Morphing Terrarium technology - 14HP
Notes: The E355 is a 14hp Eurorack module with two LFOs that use our unique morphing algorithm to create over 10,000 different waveforms. the two outputs can vary from one cycle in 12 minutes to 1000Hz, with high and low ranges available. The use of a 24 MHz 32-bit ARM processor means virtually no frequency drift.

The E355 has features to make it useful in both live and in the studio. The two LFOs are "locked" to each other in one of three ways, chosen by a panel switch:

- LFO1 and LFO2 have independent rates and the same waveshape and phase
- LFO2 has independent waveshape but the same rate and phase as LFO1
- LFO1 and LFO2 have the same rate/waveshape but variable phase from 0-360-

LFO1 can be thought of as the "master" LFO as it always has independent rate, FM, and morphing. Each LFO tracks 1v/Oct and all parameters are under voltage control. There are two LEDs that vary in brightness based on output amplitude in 128 levels.

The E355 uses the same morphing engine as the E350 Morphing Terrarium. The transition from one stored wavetable to another is broken down into 4096 calculated waves. There are 3 banks of waves to select from:

- Bank A: basic waves in order of harmonic complexity (sine, triangle, saw up, saw down, 25/50/75% pulses and noise)
- Bank B: the waves in Bank A are repeated in frequency as 1x, 2x, 3x, 4x, etc up to 8x. This allows the LFOs to have a very wide range between them if necessary or to use this as a basic audio oscillator (limited to 1khz).
- Bank C: the 64 waves taken from Bank C of the E350 Morphing Terrarium (created by Robert Rich) to go way beyond the ordinary. Sequences of notes, arpeggiated effects, pings, swoops, and lattice phase modulation are just a few of the options contained within. In the audio range these can be harsh, noisy, and crunchy.

There are also two external inputs to either sync the LFOs or to hold ("freeze") the outputs at the current stage of the waveform.

Audio-range digital delay with normal mode, plus tape & BBD emulation - 14HP
Notes: The E580 emulates the classic sounds of digital, BBD (bucket brigade), and tape-based delays with four parameters under voltage control. This 14hp wide Eurorack module accepts either +/-12V standard power or +/-15V MOTM/power. Using a 40MHz DSP and 24-bit codec, the E580 recreates the pitch-shift modulation of BBDs, including the variable bandwidth and noise floor, without costly and scarce BBD ICs. In Tape Mode, wow & flutter, tape saturation and non-linear distortions emulate classic tape units without the bulk and maintenance. There are two simultaneous audio outputs: a straight delay and a variable tapped delay. The tap position is a percentage of the main delay time. This allows very short delays (<350µs) as well as long delays (750ms). Both tap position offset and main delay time are voltage-controlled over a -5v to +5v range.

Feedback is jumper-selectable from either the tapped position or the main delay. This flexibility can generate standard rhythmic delays (feedback from main delay) or a series of pre-delay reflections (tapped delay) which sound very different from each other.

10HP DSP-based VCO module
Notes: The E950 Circuit Bent VCO is the latest unique VCO module from Synthesis Technology. Using licensed technology from the original Texas Instruments LPC speech synthesizers (such as the Speak and Spell), the E950 contains original voice ROMs and algorithms from two generations of speech DSPs. Additionally, 2 banks of 16 wavetables each from the E350 Morphing Terrarium are included for a low-cost morphing VCO.

The E950 can speak in both "normal" and "circuit bent" modes, all under voltage control. Unlike traditional circuit bent toys and keyboards, the E950 is very repeatable and controllable, adding deep new timbres to your modular synth.
