SQ-80 — Musician's Manual
Playing the SQ-80 from an External Sequencer 
Having used its built-in Sequencer, you already know that the SQ-80 can play lots of different sounds 
at once. If you already have a computer-based or stand-alone sequencer that you like, you'll find that 
you can access the SQ-80's Multi-timbral capabilities in much the same way via MIDI. The SQ-80's 
ability to "listen to" nine MIDI Channels at once (when in MULTI Mode) means that it can take the place 
of several synthesizers in your rig. If you haven't already done so, you should read the description o
 
MULTI Mode on p. 25 for a fuller understanding of how the Tracks can act as independent MIDI 
receivers. 
Connections 
The illustration to the right shows a typical set-
up involving the SQ-80 and an external Se-
quencer. Of course the SQ-80 doesn't have to
be first in the chain after the sequencer — you 
can chain MIDI instruments in any order, with
one exception. If any of the units doesn't have
a MIDI Thru jack, you must place that unit las
in the chain. (Or you could get a MIDI Thru
Box, available from a number of manufactur-
ers, which will split up the MIDI signal and 
send it to several devices at once.) 
The SQ-80 as One Synthesizer 
We'll start with the most basic sequencing situation, in which you will use the SQ-80 as if it were an 
ordinary synth, capable of playing only one sound at a time. This is how it will act in POLY mode. In 
POLY Mode the SQ-80 will respond only to information received on the Base MIDI Channel, and will 
play only the sound which is on the current Track. 
−  On the MIDI Page, set the MIDI Mode parameter to MODE=POLY. 
−  > Also on the MIDI Page, set the MIDI Channel (CHAN= ) to whichever of the 16 MIDI 
Channels you want the SQ-80 to receive on. The SQ-80 will respond only to data received on 
this MIDI Channel. If no Sequencer Track is selected, the "Straight Synth" will receive on the 
Base Channel. If you select a Track of a Sequence, that Track will receive on the Base Channel.
