Synchronizing to MIDI Clock

It is possible to control the delay time of the BPM Mono Delay effect from an external
MIDI clock source, such as a MIDI sequencer or drum machine. Any device which
can output MIDI clock can be used to control this Configuration's delay time.
If the "Tempo" parameter is turned all the way down, below 000, the value in the
display will read "EcL", which means "external clock". The delay time will now be
controlled by the MIDI clock signal received at the [MIDI IN] port coming from an
external source. If the MIDI clock's tempo changes, the MidiVerb 4 will chase it. If the
MIDI clock signal is discontinued, the delay time will remain set to the last tempo
which the MIDI clock had been running at.
The Note parameter determines what note value the MidiVerb 4 should synchronize
to. For example, if you set the Note value to 4, then you can synchronize to the
quarter-note beats of the incoming MIDI clock. If instead you set the Note value to 8t,
you can synchronize to eighth-note triplets relative to the incoming MIDI clock
signal. You can also set the Not value to a dotted-note variation, such as *, which lets
you synchronize to the dotted-eighth-note beats relative to the incoming MIDI clock
signal. For more information about using MIDI with the MidiVerb 4, see Chapter 6.
Delay & DLY
These effects are mono, less processor-intensive versions of the Stereo Delay effect,
used in the Multi Chain Configurations Delay->Realroom, Chorus->Dly->Room and
Flange->Dly->Room; the Double Configuration Realroom+Delay; and the Dual Mono
Configurations Delay:Delay, Chorus:Delay and Flange:Delay. They provide only high
frequency cutting ability with no control over the low frequencies.

Setting Delay Time Using Tap Tempo

You can adjust the delay time using a technique called "tap tempo". By tapping the
button which corresponds to the Tap parameter, you can have the MidiVerb 4 follow
your tapping and adjust its delay time to match the tempo you are using. If the
Footswitch parameter (UTILity mode) is set to Control, you can tap your delay time
by repeatedly pressing down on the footswitch.
You can also adjust the delay time using tap tempo from the audio source being
routed to the MidiVerb 4's input(s). This can be done in two ways:
• Hold the button which corresponds to the Tap parameter; or
• Hold down the footswitch (if the Footswitch parameter is set to the Control
function).
While using either of these methods, feed signal to the MidiVerb 4. This could be
done by hitting a drum, plucking notes on a guitar or keyboard, or by singing some
"doot doots" into a microphone (depending on what is connected). Note: When the
Footswitch parameter is set to the Control function, you can control tap tempo as
described above while in either Program mode ([PROG] button lit) or Edit mode
([EDIT/PAGE] button lit), unlike when using the front panel for tap tempo which
requires that you be in Edit mode. For more information on connecting a footswitch
and selecting the Footswitch parameter's function, see Chapter 2.
