The START and STOP/CONTINUE Buttons

To play the selected pattern, simply press the red START
button. The red RUN LED will light to indicate that the
selected pattern is playing. If, for example, pattern
number 15 is selected and played, the LCD panel will
read "PLAY PTN15:BR01" indicating that bar number 1
(BR01) of pattern number 15 (PTN15) is playing.
To stop pattern playback press the blue
STOP/CONTINUE button. The pattern can be restarted
by pressing the STOP/CONTlNUE button. In this case
the pattern continues from the point at which it was last
stopped, rather than starting from the beginning. Press
START to start from the first beat of the pattern.
New patterns can be selected in the pattern mode even
if another pattern is playing. When a pattern is playing,
the newly selected pattern will begin immediately after
the last beat of the first pattern.

Tempo

The linear TEMPO control can be used to adjust the
pattern tempo. The TEMPO range is from 40 to 250 (40
to 250 quarter-note beats per minute).
For more precise tempo adjustment, however, use the
TEMPO function, activated by pressing the TEMPO key.
When the TEMPO key is pressed the LCD panel will
indicate the currently set tempo: e.g. "TEMPO = 120".
Although the TEMPO control can still be used for coarse
tempo adjustment in this mode, finer control is available
by using the -1/NO and +1/YES buttons. A single,
quick press on –1/NO decrements the tempo by one
beat, and +1/YES increments by one beat. Holding
either the - 1 or + 1 buttons down causes continuous
incrementing or decrementing in the corresponding
direction. The TEMPO function also makes it possible to
precisely set the desired tempo before beginning
playback.

Real-Time Pattern Programming

NOTE
An understanding of the QUANTIZE function,
described below; is essential for effective use of the
real-time write function. We recommend that before
actually trying out the real-time write function you
should read through this section and then the
"Quantize" section below. Then come back to this
section and try out the function.
The RX15 permits programming your own rhythm
patterns using two different methods—-REAL TIME
WRITE and STEP WRITE. The most direct of these is
REAL TIME WRITE. This function lets you "play" your
rhythm on the instrument keys, adding new instruments
and rhythm lines until the pattern is complete.
First, select the pattern number you wish to program (if
you're just starting, select a clear pattern-any pattern
above 36). Enter the real time write mode (from the
pattern mode) by pressing the REAL TIME WRITE button.
The LCD panel will indicate that the real time write mode
is active, and prompt you to input the time signature of
your pattern (the flashing block cursor will be located
immediately to the right of the first number of the time
signature): "REALT.W 04 / 4". The default time signature
is 4/4 ("04 / 4" on the LCD panel), and need not be
entered if this is the time signature you need. If you wish
to enter another time signature, however, use the white
buttons labelled 0 to 9 (1/4 to 1/192) in their top left
corner. Each input must be 2 digits. To input a 3/8 time
signature, first input the 3 as "03" and confirm that it
has been entered correctly on the LCD panel. Then
press the REAL TIME WRITE button again to enter the
second part of the time signature (notice that the
flashing block cursor moves to the right of the second
time signature figure when the REAL TIME WRITE button
is pressed a second time). The second part of the time
signature is entered using the fraction markings (1/4,
1/8, 1/6, etc.) over the number buttons. The RX15 will
accept time signatures up to 99/32; 1/48 and 1/192
inputs will be ignored. Enter the 8 by pressing the button
marked 1/8 and confirm on the display. This completes
entry of the time signature.
Now press the REAL TIME WRITE button again and you
will be prompted to input the length of your pattern in
bars: "REALT.W 01 BAR". The number of bars is
entered via the white number keys, and must be input as
two digits: 2 bars is input as "02", 4 bars would be input
as "04". A pattern can have up to 99 bars.
