Alesis QSR 64 manual INPUT/OUTPUT Mode, Midi , PC 38.4kbaud and PC31.25kb, Midi and MAC 1MHz

Chapter 8: Global Settings

If the MIDI Program Select parameter is “On” and a new Bank is selected using the BANK SELECT [DOWN] and [UP] buttons, a Bank Change message (followed by the

appropriate Program Change message) will be transmitted out the MIDI [OUTPUT] connector.

If, additionally, a new Bank is selected in Mix Play Mode and any of its Channel’s MIDI Out parameters (Mix Edit Mode, Keyboard/MIDI Function, Page 2) are turned “On”, a Bank Select message (followed by the appropriate Program Change) will be transmitted out the MIDI Out connector for each of those MIDI Channels.

INPUT/OUTPUT MODE Page 11

The I/O (Input/Output) Mode determines how the MIDI [INPUT] and [OUTPUT] connectors on the QSR’s rear panel will function in relation to the [SERIAL PORT]

connector. The possible settings of the I/O parameter depend on the setting of the [SERIAL PORT] switch (located on the back panel next to the [SERIAL PORT]).

With [SERIAL PORT] set	The I/O parameter may be switched between...
to...
PC	MIDI, PC 38.4kbaud and PC31.25kb
MAC	MIDI and MAC 1MHz

If you are using a PC compatible computer, consult the software you are using to determine which PC setting to set the I/O parameter to.

•When this parameter is switched to “MIDI”, the [SERIAL PORT] will not function, and the MIDI [INPUT] and [OUTPUT] will operate normally (receiving and transmitting MIDI information to and from the QSR).

•When this parameter is set to either “MAC 1MHz” (if the [SERIAL PORT] switch is set to MAC) or to “PC 38.4kbaud” or “PC31.25kbaud” (if the [SERIAL PORT] switch is set to PC), the MIDI [INPUT] will not function (any MIDI information received on the MIDI [INPUT] connector will be ignored), and the MIDI [OUTPUT] connector may act as a MIDI “Thru” connector for the connected computer —i.e. MIDI information received from the computer will be transmitted (see below).

For information regarding connecting a computer to the [SERIAL PORT], see page 22.

✪When the I/O parameter is NOT set to “MIDI”, the QSR will not transmit any locally generated MIDI information to the MIDI [OUTPUT] connector, but will only transmit this information to the connected computer via the [SERIAL PORT]. If the computer program has its “MIDI Thru” parameter turned on, this information will be “echoed’ back from the computer to the QSR. The MIDI information coming from the computer will also be transmitted out the QSR’s MIDI [OUTPUT] connector.
