Congratulations!
You are now the owner of a device unique
within the MIDI world — the Roland ASC-10
Scale Converter!
The ASC-10 allows you to create, store and
instantly recall any one of up to eight custom-
tuned scales which can allow you to play any
type of music imaginable!
If your work requires the special tunings
demanded by Arabic, Malouf (Egyptian) or
Bouzouki (Greek) music, for example, the
ASC-10 is for you. By creating (and storing)
the special scales required by these types of
music, you can instantly select the tuning you
need — even while playing!
The ASC-10 Concept
The vast majority of Western music forms —
and instruments — are based on the twelve
tone tuning system often referred to as Equal
Temperament. In this tuning system, one oc-
tave is divided into twelve tones with adjacent
tones being a semi-tone apart in pitch. This
'equal spacing' of tones is the basis for the
name Equal Temperament (equal tuning).
Although this tuning system is used exten-
sively, there are many forms of music in the
world which use different tunings. Some types
of music use semi-tones and quarter-tones
within the same scale (Arabic music, for exam-
ple). Still other types of music use micro-tones;
intervals smaller than a quarter-tone.
By allowing you to raise or lower the pitch of
individual notes within the equally tempered
scale, the ASC-10 can create whatever tuning
system your music requires.
