FOOTSWITCH CONTROL
Now that we have the basics down, let's investigate some live performance options using footswitch
control. This is particularly useful if you're playing along with Patterns and Songs on the pads and can't
use your hands to punch buttons.
There are two jacks for footswitches (Start/Stop and Count/A/B/Fill). Always plug these footswitches in
before turning on power. Either normally open or normally closed types (the two most common
footswitch types) can be used; the SR18 determines which kind is in use during power-up.
Here's how to use the footswitches:
SET TEMPO
The SR18 must be stopped. Before playing a Song or Pattern, tap the Count/A/B/Fill jack footswitch
several times at the desired tempo. The SR18 will average the time between taps and derive a tempo,
the display will update the tempo with each tap. Tapping the TAP TEMPO button accomplishes the
same result as tapping the Count/A/B/Fill footswitch.
START A SONG OR PATTERN
When the SR18 is stopped, pressing the Start/Stop footswitch is equivalent to pressing PLAY. When
the SR18 is running, pressing the Start/Stop footswitch is equivalent to pressing STOP.
INITIATE A FILL WHEN PLAYING PATTERNS
When playing patterns, the Count/A/B/Fill footswitch duplicates the FILL button function.
CANCEL A TRANSITION FROM A TO B, OR B TO A, PATTERNS
When you initiate a Fill, an A Pattern will transition to a B pattern (or vice-versa) when the Fill has
finished playing. However, you can cancel this transition if desired. We've already explained how to do
this with the front panel FILL button. However, you can also use the Count/A/B/Fill footswitch. If you
press the footswitch before the fill has finished playing and hold it down until after the fill has played (i.e,
past the downbeat of the next Pattern), the SR18 will return to the original Main A or B Pattern.
EXTEND A SONG STEP WHEN PLAYING BACK A SONG
During Song playback, pressing and holding the Count/A/B/Fill footswitch until past the end of a Song
Step will cause that step to repeat. This is great if the soloist wants to take a few more bars.
FACTORY RESET
To restore the SR18’s factory presets, hold the SAVE / COPY button and ERASE button simultaneously
while turning on the SR18. (NOTE: This will erase all user data, including User Drum Sets, Patterns,
Songs, etc.)
