Tempo-based control of KDFX
Many parameters within KDFX can be set up to respond to musical tempo. The tempo
information can come from a number of sources: it can be Þxed within an FX Preset, it can come
from the K2500Õs internal sequencer, or it can come from an external MIDI sequencer which has
been conÞgured to send MIDI Timing Clocks to the K2500.
The procedures for using tempo from the internal sequencer and from an external sequencer
are essentially the same, with one crucial difference in one setting: in
Song mode, on the MISC
page, the Clock parameter must be set to ÒIntÓ when using the internal sequencer and to ÒExtÓ
when using an external sequencer.
The Sync parameter controls how KDFX responds to other MIDI timing commands besides
tempoÑthat is, Start, Stop, and Continue. Many KDFX parameters respond to these commands
in special ways. For example, an LFO controlling a delay will set itself to zero (or its initial
value, if thereÕs an offset) when it receives a Start or a Continue command. For this to occur, the
Sync parameter must be set to ÒRecvÓ or ÒBothÓÑnot to ÒOffÓ or ÒXmitÓ. The Sync parameter
does not affect tempo controlÑregardless of how it is set, the clock speed, either internal or
external, will always affect any parameter that is assigned to
Clock .
Note that MIDI Timing Clocks (otherwise known as ÒMIDI SyncÓ) is not the same as MIDI
Time Code (or MTC). MIDI Sync, which is used for syncing sequencers together, changes its
speed in response to tempo changes; MIDI Time Code, which is used for syncing a sequencer to
an audio or video tape or disk system, does not. KDFX (and the K2500 in general) responds to
MIDI Timing Clocks, but not to MIDI Time Code.
