GENERAL INFORMATION

GENERAL INFORMATION GENERAL INFORMATION GENERAL INFORMATION
SY2-KBD MIDI interface controls VCO and GATE
generator of the Yamaha SY-1 / SY-2 synthesizer.
Simplified block schematics of the interface installation
in the instrument shows fig. 1.1.
The interface board is the same for both SY-1 and SY-2
instruments. This manual describes only installation into
SY SY SY SY- - - - 2 2 2 2 . SY-1 is electrically the same but mechanical
construction is a little different from SY-2. So you have
to adapt the montage of MIDI sockets and LED / Reset
button and also placement of the interface board.
Wiring of the interface to instrument's keyboard circuit
and to SM-1 board remain the same for both SY-1 and
SY-2 instruments (see appendix).
The interface firmware can be revised. Actual version of the
firmware is printed on the identification label on the interface's
processor (see fig. 1.2). It is also possible to read the actual
version of firmware from the interface by MIDI System Exclusive
message.
