What is the E370?
The Synthesis Technology E370 contains 4 independent DSP-based wavetable VCOs.
Using a 'shallow' menu system (maximum of 2 pages 'deep'), each VCO can be set to 1 of 7 different operating
modes. Although the default setting is 4 separate VCOs, the 16 CV inputs can be shared, as well as each output can
be a mixture of all 4. There are 16 user presets that save the state of the entire module, without the need for an
external uSD card.
The E370 ships with 3 banks of 64 each wavetables and allows users to import their own wavetables using our free,
cross-platform tool WaveEdit. The E370 uses a mil-spec Grayhill optical encoder/switch, and like all SynthTech
modules, comes with a lifetime warranty. Size is 54HP width, only 0.85in (21.6mm) deep.

MAIN MENU
E370 Quad Morphing VCO
www.synthtech.com/eurorack/e370
The Main Menu is like a table of contents. The encoder is used to
highlight the function, and the encoder knob is 'clicked' (like a mouse)
to go to that page. The current E370 firmware is available at the link above.
The color scheme is customizable.
There are 16 presets to store the setting of the module. This includes
any user-loaded wavetables. Each preset can have 512 different
user wavetables (8 banks) plus the 192 factory waves.
The green dot in the lower right turns red (default) when the memory
is being written.

Summary of Contents for Synthesis Technology E370 Quad Morphing VCO

Page 1: Main Menu
What is the E370? The Synthesis Technology E370 contains 4 independent DSP-based wavetable VCOs. Using a ‘shallow’ menu system (maximum of 2 pages ‘deep’), each VCO can be set to 1 of 7 different operating modes. Although the default setting is 4 separate VCOs, the 16 CV inputs can be shared, as well as each output can be a mixture of all 4. - Page 2 Controls and Jacks Each VCO has the following panel controls and CV inputs/audio output. Pitch control: COARSE, FINE and 1V/OCT are internally summed together and presented to the VCO as a single CV source. FM: this is a separate CV Frequency Modulation input to each VCO. The panel control is a 0-100% attenuator for the CV applied to the FM jack.
- Page 3 Freq & Chords Page The top-level page is a status screen which shows all 4 VCOs and their settings as they relate to ‘traditional’ VCOs. The displayed parameters are individually set by highlighting the VCO you want to edit, clicking, and going to the second page (middle photo).
- Page 4 Chord Select is the method used to select which Chord in the table is being played. To ‘play’ in Chord mode: a) Go to the Frequency page b) For each voice you want to play, select Chordn as a 1V/O source, where n is which of the 4 ‘columns’...
- Page 5 Presentation Pages These 3 pages are different visual representations of the state of the 4 VCO outputs. • Waves – displays the wavetable used or a data screen for Noise • Lissajous – X/Y plots of the VCO wavetables. The X and Y axis can be selected as VCO1-4 •...
- Page 6 Loading and Saving Patches There are 16 user patches that are stored in the E370’s internal memory (no uSD required). Each patch saves the complete, entire state of the E370: all the pages, referenced Wavetable banks and all the settings. The panel pot positions are not saved. Patches must be saved/recalled via the encoder system.
