The TM-2 kit replaces the old unreliable keybed in any Sequential Circuits Pro-One with a modern Fatar semi-weighted one. This is the same keyboard used in many modern synths from DSI, Moog, Novation and many others. The TM-2 kit includes everything you need and requires no modification of the Pro-One.
The Pro-One is a great synth, but many users (myself included) are just fed up with the endless clackety-clack, dry bushings, dead or double-triggering keys and the work and costs this entails. Give yourself and your Pro-One the gift of smooth playability!
The TM-2 kit - a look inside
Some Pro-Ones have had their keyboard cable socket replaced. See the pics for "original" and an example of "replaced" (with round milled holes).
If your socket has been replaced, please take a pic and send with your order so we can provide the correct adapter card.
Open up your Pro-One. There is a ribbon cable going from the keyboard to this socket, make a note of which direction it is inserted before gently pulling it out to check what type it is.
