Operating Systems for DSI Products
All of our synths have multiple processors for performing different functions, and each processor has its own flash memory and operating system.

What are the current versions?
The table below shows the current operating systems for all of the DSI products.
Please note that different Evolver models have different OS versions. That's because all of them started with initial versions of 1.0 and were updated from there. Main version 3.0 on the Evolver Desktop is essentially the same as version 1.3 on the Evolver Keyboard.

Do I really need to update my operating system?
Most of the updates are for very minor bug fixes and, unless noted otherwise, do not add features. It is probably not necessary to update the operating system unless you have encountered a problem of some sort.
Two exceptions are Evolver Desktop Main version 3.x and Poly Evolver Rack Main version 2.x. The Evolver Desktop OS adds features and both OS versions improve compatibility with other Evolver models. See the specific OS pages for details.
How do I update my operating system?
The operating systems are available for download in SysEx (short for "MIDI System Exclusive") format. (Some updates may also require an upgrade to the hardware which typically means opening the instrument and replacing socketed parts.) Updates are loaded into the instruments via MIDI using one of several methods, including:
- The instrument's editor/librarian software
- A MIDI sequencer capable of opening and playing SysEx files
- A SysEx utility
There are a couple of utilities we recommend: MIDI-OX for Windows OS and SysEx Librarian for Mac OS.
Note: For MIDI-OX, the recommended Low Level Output Buffer settings are Size = 1,024 Bytes and Num = 128.
