"This is one of the most versatile delay units for Eurorack analogue modulars available. What makes it special is a cv-controllable additional tap (of the multitap delay line). You can vary the offset of this, creating amazing polyrhythms or simulating adjusting the tape heads.

Operating modes:
clean
BBD: simulates a bucket drigade device based delay
tape: simulates a tape echo
The delay output always gives the full delay time set with the according control, the tap output gives a delay time which stands in a percentual relationship to the delay time. This value is being set with the Tap-Offset control and/or the offset CV. Send the two outputs to two channels with hard L/R panning and you will get nice ping pong delays.

Feedback can be either positive or negative and goes up almost to a very dense self-oscillation. A jumper on the PCB sets if the fed back signal comes from the delay out or the tap out. Latter setting gives very interesting effects when modulating the tap parameter.

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."
