The QS can communicate directly with Mac or PC computers via its [SERIAL PORT]
connector. Using this connection eliminates the need for a MIDI cables and a separate
MIDI interface.
Here’s how it works:
1) Run a single serial cable from your computer’s serial port to the [SERIAL PORT]
connector on your QS.
2) Set the rear panel [ PC / MAC ] switch to either PC or MAC, depending on
what kind of computer you are using.
3) Set your QS to listen to data over this direct serial connection, instead of MIDI.
To do this, press [EDIT SELECT] to begin editing; then press [BANK ] to access
Global Edit Mode; then press
[ PAGE] until the lower line of the LCD reads
I/O. (If you overshoot, just press the [PAGE ] button to get back.) Once there,
use the [VALUE] buttons to change the setting from MIDI to whatever best
matches your computer. There are three options:
•
PC 38.4Kbd. Use this setting if your computer is a PC and its serial port runs
at 38.4 kilobaud.
•
PC 31.25Kbd. Use this setting if your computer is a PC and its serial port
runs at 31.25 kilobaud.
• MAC 1MHz. Use this setting if your computer is a Macintosh.
Please note that if the rear-panel selection switch is set to [MAC], your QS will not
show you the two PC choices. Likewise, if the switch is set to [PC], then the Mac setting
will not show up in the display.
