SQ-80 — Musician's Manual
[CREATE/ERASE] CREATE/ERASE PAGE
For Creating new Sequences or Songs, Erasing existing Sequences or Songs, and Erasing all
Sequencer Memory.
Until a Sequence or Song has been created, it is just an empty, undefined slot in the SQ-80's Memory,
and cannot be selected or played. An undefined Sequence will be shown on the Sequence Select Page
as XXX - 05, instead of SEQ - 05, which is how a Sequence appears after it has been defined. The first
step in recording a new Sequence is to Create, or define, a Sequence in one of the empty Sequence
Locations.
When you press the CREATE/ERASE Button, the Page appears as shown below:
Available Memory
First notice the upper-right segment of the Display — [FREE=__]. This tells you the number of Bytes
of Sequencer Memory available. A Byte is eight Bits of digital information. Each note you play uses a
little over three Bytes, so when all the Internal Sequencer Memory (64k Bytes) is available, you can
record about 20,000 notes.
These numbers reflect notes played (Key Events) only, and do not take into account Controllers such as
Pitch Bend, MOD Wheel. Pressure, etc. Controller values are recorded by a digital sequencer as a steady
stream of numbers, and thus use up available memory much faster than Key Events. When you record
using a lot of Controllers, you will expend the available memory rather quickly.
ACTIVE CONTROLS:
1, CREATE NEW SEQUENCE
A new Sequence can be Created in any of the sixty Sequence Memory Locations that doesn't
contain a defined Sequence — where XXX appears instead of SEQ on the Sequence Select
Pages. It is important to note that at the time a Sequence is created, you must define the Time
Signature of that Sequence. The Time Signature cannot be changed after the Sequence has been
created.
