Sequential Circuits ProphetŪ600 TEENSY Board for GLIGLI upgrade DISCONTINUED by manufacturer.
GLIGLI instruction #5 alert:
"Plug the E5 wire into socket number 30..."
When installing any upgrade or modification into your vintage Prophet 600 synth follow the Hippocratic Oath: First do no harm. Careless installation of the E5 wire carries a high risk of damaging the CPU's 40-pin socket. This procedure can create a self inflicted failure that will disable your Prophet 600 and require technical service to repair. Wine Country has seen this failure firsthand in GLIGLI updated Prophet 600s many times, and unfortunately the cost of repair always exceeds the cost of the upgrade. If you choose to follow STEP 5 in GLIGLI's instructions we urge CAUTION when installing the E5 wire. Our modified TEENSY ++ PC board eliminates this loose E5 wire and any possible DAMAGE to the 40-pin socket and your Prophet 600 during or after installation of this upgrade.
The TEENSY++ PC Board modification significantly improves the MIDI features and sound of a Prophet 600. Unfortunately this drop-in ready TEENSY++ PC board modified & ready for use with a Prophet 600 is SOLD OUT, and our stock of TEENSY boards is now depleted.
Basic installation & operational instructions were included. Installation required absolutely NOSOLDERING, just plug in & play. Wine Country's proprietary TEENSY adapter eliminated that single jumper wire for pin #30 of the 40-pin CPU socket which prevents accidental damage to your Prophet 600's CPU socket's pin#30 during and after the installation process.
Our TEENSY++ upgrade already included the original Prophet 600 factory sound program data so it was ready to play upon installation. A SysEx file of original factory sound program data was available upon request when purchasing a TEENSY++ upgrade from Wine Country.
A modified TEENSY++ PC board installed in a Prophet 600 is pictured below.

Ali from Raleigh NC emails..
"yes I had ordered another one .I finally got stable tuning out of the instrument..and the sound of the instrument is wonderful .I am working on another p600 and wanted the chip for it also".
Alexey from Switzerland emails..
"Hello, since seeing positive feedbacks on your site about this mod I would like to leave one too. The teensy was extremely simple to install and worked straight away tuning the whole thing to a degree it was never tuned to and the sound does feel “refreshed”.
Really happy with it, thanks! Alexey"
Carl from Blacksburg VA emails..
"I successfully installed the Teensy++ mod from Wine Country Sequential into my Prophet 600 in a little less than a half-hour's time. It was awesome to simply drop it in and restore my patches; no soldering, no fuss, etc. I really appreciated the prompt response and answers to my questions from Linda in inside sales and my overall experience with the Teensy++ mod from Wine Country Sequential was top notch! With the new mod, my Prophet 600 is like a whole new instrument... lots of new sonic territory to explore!
Erik from Norway emails..

Best regards Erik"
