The Synthesis Technology E350 Morphing Terrarium is a unique wavetable VCO with two independent waveform outputs. Unlike similar designs, the E350 is a fully self-contained, 1v/oct VCO. What sets the E350 apart from previous wavetable oscillators is voltage-controlled morphing.

The module ships with three banks of 64 "basic" waveforms (192 total). Each bank of 64 waves is arranged in memory as an 8x8 array (like a chess board). The "rows" are the X direction and the columns are the Y direction. The two panel controls and the two external control voltages (Morph X and Morph Y) are used to "point" to where in the array we use for the signal that is available at the XY Out. The third control voltage is called Z Morph, which determines the waveshape at the Z Out. The Z control voltage scans the wavetable bank from wave #1 (think as row 1, column 1) to wave #64 (row 8, column 8). For example, if Morph X is set to 2, and Morph Y is set to 5, the signal at the XY Out is the waveform stored at row 2, column 5 (the 13th wavetable). The Z Out is completely independent of the XY Out, so if the Morph Z knob is at 48, then the 48th wavetable (row 6, column 8) is the output.

The wavetables in each of the three banks are very carefully ordered by rows. In general, scanning in the X direction will generate a smooth progression of timbre. Each row, however, is different! There are sine banks, pulse width modulations, filtered noise, and even male/female vocal formants. So you can see that scanning in the Y direction (in a column) will be extremely varied, and the beauty is that you can scan in both directions simultaneously.

But we were not content with just indexing through the table one wave at a time. Instead, the E350 implements a proprietary smoothing/anti-aliasing algorithm that allows the two outputs to be a continuous blending of one wave to another. The algorithm calculates 128 "in-between" waveforms, so that the 192 "basic" waveforms are really expanded to over 24,000 individual timbres! As you adjust the panel controls, or add external modulation (from LFOs, envelopes, etc.), the E350's outputs are "glitch-free" and will provide you with a near-infinite range of tonal possibilities. If you like the glitches of older wavetable VCOs, there is a jumper option on the PCB to restore this behavior.

But we wanted to do even more, so we added a three-position range switch for using the E350 as the world's best LFO. At the lowest setting, the E350 will cycle once every 13 minutes and be repeatable within 20μsec. The Sync signal can be used to reset both outputs to zero (hard sync) like any other VCO. The C bank of waveforms are specifically designed to be used in LFO settings (although they will output audio timbres as well). The LFO waveshapes include everything from 'chirps,' to sequences of individual notes, to noise gates, to sample & hold effects, to exponential/logarithmic sweeps. Like quadrature outputs? The E350 can have variable phase outputs under CV control.

There is nothing like the E350 in any modular format. In many patches a VCF is not needed because the timbres that are generated are already smooth and harmonically "correct." From the precise tracking to the incredible 24,000 possible waveforms, the E350 sets the standard in modular oscillators.

Note that in quadrature mode (jumper option), XY Out and Z Out are offset by a variable phase (0 to 359 degrees) as set by Morph Y control.
