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.

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
E352 Cloud Terrarium
www.synthtech.com/eurorack/e352
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).

Summary of Contents for Synthesis Technology E352 Cloud Terrarium
- Page 1 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.
- Page 2 Controls and Jacks There are 3 CVs that are assigned, based on what mode you are in. Each CV (called X, Y and Z) has a dedicated ‘offset’ or PARAMETER and an external CV in (-5V to +5V range) with a dedicated attenuator. It is important to note, just like on all SynthTech modules, the attenuated CV is *added* to the PARAMETER knob position.
- Page 3 Morphing Clouds Mode The Cloud+Morph mode adds the ability to Z Morph the Bank at the same time the Cloud algorithm detunes the VCO cluster. The 3 parameters are mapped as follows: • X – Spread • Y – Chaos, which is now the filtered noise amount + BW combined •...
- Page 4 Detuning Mode This is a new mode, added at V1.3 of the firmware. The signal at OUT2 is detuned from the signal at OUT1 by either a fixed amount from a table or ‘smoothly’ by a variable CV. Each output can have its own wavetable or standard shape, and can be Z Morphed.
- Page 5 Waves/Lissajous/Visual Display/Eye Candy Waves – not to be confused with a ‘real-time oscilloscope’, this display shows the data in the corresponding wavetable of each output (or tabular data for Noise and Sample Player). The display will not reflect FM or frequency changes. The ‘Expanded’ view shows more vertical detail. In the lower-left corner, there will be a H/M/L shown for High/Mid/Low frequency range.
- Page 6 Frequency Page The top display shows the frequency of OUT1, based on a single-cycle wave or wavetable. Note that wavetables can have multiple zero- crossings and hence a higher frequency than displayed (for example, the first row of ROMA sine harmonics). At lower frequencies (L range) the display shows the period of the output.
- Page 7 Importing Using WaveEdit (USR Banks) The Bank file used in Sample Player does not have a ‘sample rate’ associated with it like a standard sampler The file length is fixed at 16K 16bit words + the WAV header. This will be reported (based on the OS) as either 32KB or 33KB length.
- Page 8 Step 3: Note the 2 preview panes are “edit buffers”. In order to actually save the final sample file, click the Import tab at the very bottom left corner. Then you can Save Bank As… to your computer/uSD card. Note that the file system in the E352 uses the old MSDOS 8.3 file naming format. Longer file names will be displayed in a truncated version.
