The Synthesis Technology E352 combines the latest 200MHz 32-bit ARM DSP with SynthTech's Cloud and Morphing algorithms found in the legendary E340 Cloud Generator and the E350 Morphing Terrarium.
Some important features:
- User-defined wavetables loaded via microSD card
- Color 240 x 320 TFT LCD display
- Grayhill mil-spec optical encoder for data entry
- 16-bit wavetables (versus 8-bit for the E350) for 5x lower noise & THD
- Contains all 192 of the original E350 wavetables
- LFO mode, variable Glitch Energy and other added features
VCO Architecture
The E352 has a single VCO, but 2 seperate audio outputs. The outputs are determined by the VCO Mode setting. They do not necessarily have to be the same pitch (Detung Mode).
The VCO is based upon a unique implementation of wavetable synthesis using 256 fixed-sample-length tables of 16-bit values. Each bank in memory consists of 64 wavetables, in an 8x8 array (like a chessboard). Our proprietary DSP algorithms then allow either smooth or 'glitched' morphing between the wavetables in various ways. The E352 comes with 3 factory banks (192 total waves) and internal FLASH memory to hold 26 user-defined banks. This allows over 1,650 individual wavetables to be accessible. The free, cross-platform WaveEdit program is used to generate and import WAV files to user Banks.
Each VCO has 3 CV inputs (called Parameters or PARMs) which the VCO mode assigns to functions within that algorithm. In addition, there is a hard SYNC input, and the FM can be set to exponential or 3 ranges of TZFM (Thru-Zero FM).
Color LCD/Navigation
Everyone hates 'menu-diving', us included. That's why we focused on making the most 'shallow' menu system possible. Everything is just 1 or 2 clicks away. No endless screens and pages to remember. The encoder is a mil-spec Grayhill optical encoder with a 25yr typical life. And if it ever needs replacing, it's on a easy to access cable assembly.
The color LCD lets you customize the color scheme with 64 different colors to pick from.
There are several included 'visual aids' that can be displayed on the LCD:
- Each of the VCO output waves/noise modes, updated 20FPS
- Lissajous figures
- Real-time FFT spectra of the audio output when in the 2-op FM mode
- Graphical maps of the X and Y PARM CVs
- Interesting 'Eye Candy' effects
User Wavetables and Patch Storage
You can load your own sets of wavetables using the uSD card interface. The uSD card is NOT REQUIRED to run the E352. It is also used for firmware updates. The free application WaveEdit is used to format the wave data and bank data into the proper format used inside the E352.
The E352 has internal non-volatile memory for storing both User wavetables/Banks and for Patches. A 'Patch' stores the menu settings. There are 8 Patches available, and a Patch can be quickly recalled for live performances.
VCO Modes
Although the E352 excels at smooth morphing between wavetables (first introduced in the E350 Morphing Terrarium in 2010), traditional VCO waves such as saws, pure sines, and filtered noise (using a 4-pole resonant lowpass ladder filter) can be selected. Thru-zero, linear FM (in 3 ranges) can be used on not just triangle waves (as in an analog VCO) but with ANY waveshape or any wavetable. Here are all the different modes.
- Morphing - Use 3 CVs to select where in the 8x8 bank of wavetables the output is generated. This is the E350's mode.
- Morph + Phase Shifting - used when mixing with another VCO (or driving laser galvos). Audio-rate modulation generates classic PM tones. Wavetable morphing plus a voltage-controlled phase shifter.
- Morph + Wavefolder - can you wavefold a wavetable? Sure you can...now.
- Cloud Generator - this is an improved E340 mode. Not just saws or sines, but can 'cloud' any wavetable. A 'cloud' is a set of detuned copies (the 'supersaw' effect)
- Morphing Cloud Generator - combination of Cloud + Morph modes.
- 2op FM - 2 operator Yamaha FM. Not limited to just sine waves, you can use wavetables as well.
- Noise - 6 types of noise plus a resonant, Moog-style ladder filter
- Sample Player - a 'lo-fi' sample player that treats the selected Bank as 1 giant WAV sample, with separate Start and Length points under voltage control.
How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
