Alesis QSR 64 manual Using An External Sequencer

Chapter 3: Connections

USING AN EXTERNAL SEQUENCER

The MIDI keyboard or controller (such as the QS7 or QS8) can generate MIDI signals that are recorded by a sequencer. On playback, the sequencer sends this data to the QSR, which then serves as a multitimbral sound module (in Mix Mode). The sequencer can generate data over several channels; in Mix Mode, the QSR can be programmed so that individual Programs play sequenced data on specific channels. Example: If the sequencer transmits a piano part over channel 1, a bass part over channel 2, and a drum part over channel 10, you could set up a QSR Mix so that a piano sound plays only the MIDI data assigned to channel 1, a bass sound plays only the MIDI data assigned to channel 2, and drums play only the MIDI data assigned to channel 10. The QSR can store up to 100 User Mixes.

Connect your master keyboard’s MIDI Out to the sequencer’s MIDI In (if using a computer-based sequencer, connect to the computer’s MIDI interface’s MIDI In). Connect the sequencer’s MIDI Out to your keyboard’s MIDI In. Finally, connect your keyboard’s MIDI Thru to the QSR’s [MIDI IN] (the Thru signal carries a replica of what appears at the keyboard’s MIDI In, which is the same as the sequencer’s MIDI Out). Note that the I/O parameter (Global, page 11) must be set to MIDI.

If you are driving other MIDI gear (such as an expander module or MIDI-responsive signal processor), you’ll usually drive these from the sequencer if it has additional MIDI outputs. However, you can also use the QSR’s [MIDI THRU] connector to drive other modules since the Thru carries a replica of what appears at the QSR’s [MIDI IN], which is the same as the sequencer’s MIDI OUT.

Note: For most sequencer applications, the QSR’s “Mix Group Channel” parameter (on page 13 in Global Edit mode) should be set to OFF. See page 112 for more information.
