"The synthesis technology e580 resampling mini-delay emulates the classic sounds of digital, bbd and tape-based delays with 4 parameters under voltage control. the 14hp wide euro module accepts either +-12v euro standard power or +-15v motm/frac power. using a 40mhz dsp and 24-bit codec, the e580 recreates the pitch-shift modulating of bbds with the variable bandwidth and noise floor without costly bbd ics. in tape mode, wow& flutter, tape saturation and non-linear distortion model classic tape units without the bulk and maintenance. there are 2 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 (<350us) 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."

Synthesis Technology e355 Morphing Dual LFO

"The e355 is a 14hp euro module with 2 lfos that use our unique morphing algorithm to create over 10,000 different wave forms. the 2 outputs can vary from 1 cycle in 12 minutes to 1000hz in 2 ranges and the use of a 24mhz 32-bit arm processor allows the frequency to be stable over temperature and during years of use.

It has features to make it useful in both live and studio use. the 2 lfos are "locked" to each other in one of 3 ways, selectable by a panel switch:
lfo2 and lfo1 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 and wave shape but variable phase from 0 -360 degrees
lfo1 can be thought as the ‘master’ lfo as it always has independent rate, fm and morphing. the lfos track 1v/oct and all parameters are under voltage control. there are 2 leds that vary brightness based on output amplitude in 128 levels.

The e355 using 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, tri, 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, ..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: these are the 64 waves in bank c of the e350 (designed by robert rich) to go way beyond the ordinary. sequences of notes, arpeggiation effects, pings, swoops and lattice phase modulation are just some of the delights contained. in the audio range these can be harsh, noisy and crunchy.

There are 2 external inputs to either sync the lfos or to hold ('freeze') the outputs.

Specs:
Cv inputs: -5v to +5v, dc to 8khz.
Frequency range (bank a and c): low (12min/cycle – 2hz) high (8sec/cycle to 124hz)
Frequency range (bank b at 8x settings): low (1.5min/cycle -16hz) high (1hz – 1020hz)
Power supply range: +-9v to +-15v (euro and motm connectors provided)
Power supply current (typical): -12v @12ma +12v @ 32ma
Size: 14hp x 17mm depth behind panel"
