eNow the TR-909 is ready for Step Write
or Pattern Play.
If you have changed the Banks, please be
aware of the following points.
Note 1
It is not possible to play the Rhythm
Pattern in Bank | and the one in Bank
| continuingly. This is because turning
the TR-909 into the Track Play mode
is necessary before changing the Banks.
Note 2
Later when programming a Rhythm
Track (one whole music piece) by com-
bining the Rhythm Patterns you have
written, you are not allowed to use the
Rhythm Patterns in different Banks.
Please remember this, and try writing
the Rhythm Patterns you may need for
programming a Track into the same
Bank.
C. Key Point for Writing
In the TR-909, Rhythms are written in
a step sequence process which breaks
each measure (and each beat) down into
a series of steps. Before start writing a
Rhythm, you need to modify the score
accordingly. Let's study the score
shown below. In this modifying pro-
cedure, timing value is ignored as per-
cussive sounds are all very short. Also
the TR-909 allows selection of 3 other
Scales apart from used in this ex-
ample, which is to change how many
steps there wil! be for each beat. There-
fore, even triplet or 32 beats can be
written. (The details will be explained
later in "Advanced Course'')
