62 MidiVerb 4 Reference Manual
Let’s say you want your keyboard’s modulation wheel (controller #1) to control how
much reverb is heard. Since Mod Y is wired to the Wet/Dry Mix, you would first
assign Mod Y to be 001. Next, you set the amplitude for how much of the Mix
parameter’s range you wish to be able to control from the mod wheel. For full
control, set the AmpX to 99. At this point you may not hear any effect. This is
probably because the effect’s Mix parameter is set to 100%; the mod wheel is adding
to the parameter’s value, but it has nowhere to go. If you bring the Mix parameter all
the way down to 0%, the mod wheel will have total control (move the mod wheel all
the way up and down to move the Mix parameter from dry only to wet only).
If you are using an effect whose modulated parameters are of the either/or kind (like
the Lezlie’s Speed parameter; it is either slow or fast), the Modulator will have no
effect if the parameter is set to its “second” setting and the Modulator’s amplitude is
set to a positive value. Once again, this parameter is already at its maximum setting
and cannot go any further. Likewise, you will not hear any effect if the parameter is
at its first or minimum setting, and the Modulator’s amplitude is set to a negative
value.
Here’s another example. Let’s say an effect parameter (which is controlled by Modu-
lator X) is set to 75% of its maximum setting. If Modulator X has an amplitude of
100% and the controller designated as Modulator X is at 100%, the effect parameter
will be at its maximum setting. If Modulator X’s amplitude is 50%, the parameter will
be halfway between its programmed setting of 75% and its maximum setting of
100%. If, on the other hand, Modulator X’s amplitude is -99, the parameter will be at
its minimum or 0% setting.
Controlling Delay Time via MIDI Clock
When using the BPM Mono Delay Configuration, it is possible to control the delay
time 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.
First, select a Program on the MidiVerb 4 which uses the BPM Mono Delay
Configuration. Then turn the “Tempo” parameter all the way down until the value in
the display reads 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.
An additional parameter, called Note, is used to determine what note value the
MidiVerb 4 should synchronize to. 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 Note 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.
