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.
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.
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.
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.
