using Auto allocation. Using the same example, if Studio Y had 2 PAUs hard-assigned to
FXBus1, even though the FX preset is only using one of the PAUs, then that second PAU would
not get reassigned to the reverb, and the reverbÕs transition would be smooth.

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 a studio, it can come from
the K2600Õs internal sequencer, or it can come from an external MIDI sequencer that has been
conÞgured to send MIDI Timing Clocks to the K2600.
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 Int when using the internal sequencer and to Ext when
using an external sequencer.
Note that MIDI Timing Clocks (otherwise known as MIDI Sync) 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 K2600 in general) responds to MIDI Sync,
but not to MIDI Time Code.
Tempo Within an FX Preset
Some algorithms have a Tempo parameter, which allows certain time-based functions, such as
LFOs, envelopes, or delay lengths, to be expressed in beats per minute (BPM). A second
