* MTG Pro One Turbo CPU *
The ultimate upgrade for one of the world's most loved monosynths! |
|
|
Turbo CPU The MTG Pro One Turbo replacement CPU Module is a drop-in replacement microcontroller for the Sequential Circuits Pro One's 8021 CPU (AKA P8021/8021H/P8021H). Features:
|
|
Turbo CPU + MIDI The above plus a MIDI In/Out interface board that adds the following features*:
|
|
Turbo CPU + MIDI + CV (Beta) For the handy DIYers, add a tiny MCP4728 daughterboard to the Rev D MIDI board (and a few wires) and analog control over MIDI will be yours! Simply connect 2 additional wires from the MTG TurboCPU and then tie into the Pro One using 4 CV wires. No trace cutting or case butchering! See the firmware and manual(s) below.
Alternatively, you can order a similar one yourself here: MCP4728 Breakout Board

Ordering Information
|
Please note: I am building these by hand for now. Quantities at any given time are limited. Please order off my eBay page (and see this notice). (As mentioned above, if you would like the CV/DAC option pre-installed email me at the address shown at the bottom of this page). |
Firmware
|
Please read these Release Notes.
|
System
|
Some sample .SYX Sys Ex files for reading and writing the settable parameters (zipped). These files are for MIDIOX (or a similar app) but the included text file lists all the commands and you can cut and paste them into your favourite application/tool.
|
Free Software
|
The software below is a Windows "Editor/Librarian" that I use for development and testing of the TurboCPU+MIDI. It allows you to setup the various parameters more easily as well as manage sequencer files. I have also included a feature for easy firmware upgrading of the flash. The CV/DAC page is a work in progress.
Download TurboCPU.exe v1.41 here (includes v1.40 firmware upgrade file). It's just a basic Sys Ex application so anyone out there is welcome to make a prettier one. This is now a signed installation package (setup.exe). If you would prefer just a standalone ZIP please ask. |
"It came today and it's now in my Pro-One. Everything works perfectly! Thanks again!" - Ed (Canada) "This is GREAT! Thanks. - J.L. (Canada) "Thank you, item as described, my Pro One is singing again." - A.N. (Australia) via eBay "GRANT you are a genius, this is so much fun. Support this guy, its essential for a pro-one and expands its so much beyond." - D.B.S. (USA) "I got the CPU and it's now installed. It's absolutely perfect!!! - R.K. (Finland) "As someone who's been repairing Pro-Ones for ten years, I can testify that this new CPU is definitely a "plug and play" replacement. It also offers increased sequencer options, and has a built-in MIDI interface that is the EASIEST and most functional of all such devices I've seen applied to the Pro-One over the years. Definitely worth the purchase (I've bought several for repairs -- no complaints)." - GMM (USA)
