The serial port on Alesis QS7 is mini-din style, like a Mac serial port or a PS/2 style mouse. There is a switch to choose between Mac or PC mode for the port. From what I read for Windows you will need to install a Alesis serial port MIDI driver but none mention on Mac OS.

Sound Bridge is a utility program, that compiles custom samples from a variety of sources into the QuadraSynth Voice format, and then downloads those Voices to an Alesis - compatible PCMCIA Sound Card via MIDI SysEx to a QS6, QS7, QS8, QuadraSynth Plus Piano or S4 Plus.
