What is the E352? 
 

The Synthesis Technology E352 is a dual output, wavetable VCO that replaces the older E340 Cloud 
Generator and the E350 Morphing Terrarium, while adding over 30 new features. 
 
Shipping with all 192 waves of the E350, it also allows 26 User Defined banks (a bank is a 8x8 matrix of 
64 individual waves) which are easily loaded using the free WaveEdit application and a uSD card. The 
WaveEdit program supports PC/Mac/Linux and has a full toolbox for importing, drawing and creating 
wavetables. The uSD card needs to be FAT32 formatted, 32GB size or smaller (no speed requirement). 
The card is not required for normal operation, only to load files into the E352. 
 
The large color TFT screen is used to select the modes and parameters, using a “shallow” menu: only 1 
page is below another page. The menu items are selected by rotating the encoder left or right (to go 
‘back’ or ‘forward’) and then ‘clicking’ the encoder knob. SynthTech modules come with a lifetime 
warranty. Support is primarily via the SynthTech Modular Group on Facebook. 
 

Watch the tutorial video 

 
Go to the link at the top of this sheet and watch the overview videos. This will touch on all the different 
modes of the E352 and show you the ‘shallow’ menu system. 
 

MAIN MENU 

 

 

 

 

 

 

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 color scheme is customizable. 

 

There are 8 presets to store the setting of the module. These presets 
are separate from the 26 USR banks, which are loaded using the 

File

 

menu. You can only read from the uSD card, patches cannot be saved 
to it. Patches and USR banks are stored internally in the E352. 

 
 

 

 

 

 

The green dot in the lower right turns red (default) when the memory 

 

 

 

 

 

is being written. Do not power off when this is active. 

 

 

 

 

 

 
Please check the link above for the latest firmware version (currently 
V1.4).
