E355 Morphing Dual LFO

SKU: MOT_E355 Maker:


The E355 is a 14HP Euro module with 2 LFOs that use our unique morphing algorithm to create over 10,000 different waveforms. 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.

The E355 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 waveshape 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 morphine 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.
