21st-century overhaul/rewrite for the classic but rare Kawai SX-240 which makes it possible to control the parameters with any MIDI faderbox. Written by Bob Grieb of tauntek.com.

Features

• CC control of SX-240 parameters (upper and lower voices) [CC parameter sheet, PDF]
• MIDI On/Off for lower voices
• Synth remembers the MIDI channel even after switching it off
• Patch and sequence save/restore via MIDI Sysex [Format sheet, PDF]

More information by the author of the firmware here.

Note: The code is also available for download via Bob’s page, so you could burn it yourself. When you are buying the firmware chip here, the firmware author gets a share – meaning that you are supporting the work of a brilliant engineer with a true love for vintage synth gear.

The update consists of two 27C256 chips programmed with the new firmware; when inserting the chips into your synth, take care to put the MASTER chip into the „Master Prom“ socket, and the SLAVE chip into the socket for the „Slave Prom“.
