TEMPO DELAY
Tempo Delay features a stereo digital delay (similar to MultiTap) where the tempo is controlled
by an assignable modulation source, like a foot switch.
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section.
03 — Tempo Delay Time Range: various
This parameter selects one of twelve different settings to determine the delay rate: 1/32 note,
1/16 triplet, 1/16 note, 1/16 dotted, 1/8 triplet, 1/8 note, 1/8 dotted, 1/4 triplet, 1/4 note, 1/4
dotted, 1/2 triplet and 1/2 note.
04 — Internal Clock Tempo Range: 050 to 250 bpm
This parameter determines the number of beats per minute (bpm) for the tempo when controlled
by the internal clock. If MIDI Clocks or Footswitch1 Tapping is assigned (parameter 06), this
parameter does nothing.
05 — TempoDelay Fine Tune Range: -99 to +99
This parameter allows you to fine tune the delay time. Lower values have a faster speed.
06 — Tempo Control Range: Internal Clock, MIDI clocks, FtSw1L Tapping
Determines how the tempo will be controlled. In order for Foot Switch 1-L to work as a
controller, it must be assigned as a DP/4+ Controller in System•MIDI mode (parameter 45). The
foot switch is then pressed twice (tapping quarter notes) to set the tempo. Continued tapping on
the foot switch will cause the tempo to change, because the DP/4+ always reads the sum of the
last two presses. This could be a useful technique for songs or arrangements where the tempo is
constantly changing.
07 — Tempo Delay Regen Range: 00 to 99
Determines the amount of signal that will be fed from the output back into the input, increasing
the number of repeats in the delay.
08 — Tempo Delay Pan Range: -99 to +99
Sets the location within the stereo spectrum for the delayed signal.
09 — Tempo Delay Smoothing Range: 50µs to 10.0 s
Controls the average period of incoming MIDI clocks. Longer smoothing times provide more
stable results and less clicking; shorter smooth times have less doppler, and track tempo changes
faster. We recommend a setting of 200 ms for starters.
10 — Tempo Delay Pan Range: -99 to +99
Sets the location within the stereo spectrum for the delayed signal.
