ROTARY SPEAKER EFFECTS
If ROTARY SPKRS is selected in the field, you will see this screen:
In ‘the good ol’ days’, the sound of an organ was enhanced using a rotary speaker (it was also a
popular one-off effect on guitar and other sounds as well). A rotary speaker is a speaker
enclosure that has a speaker on a motor that literally spins round and round. This ‘throws’ the
sound around giving a very pleasing effect. However, these rotary speakers have two speed
settings, slow and fast, and using a switch, you can switch between slow and fast. The slow
speed gave a smooth undulating effect whilst the fast setting gave a kind of tremolo-cum-
vibrato effect. The ROTARY SPKRS selection allows you to simulate this. The parameters are:
This sets one of the rotary speaker speeds. Typically, this will
be used to set the speed of the slow rotary speaker effect but
it may be used as the fast rotary speaker effect if you wish as
the CD3000XL simply toggles between SPEED1 and
SPEED2.
This sets the second of the rotary speaker effect speeds.
On a ‘proper’ rotary speaker, because of mechanics and
inertia, it takes a certain amount of time for the speaker to
change from the slow speed to the fast speed and vice versa.
This parameter allows you to set the time in seconds it will take
to go from SPEED1 to SPEED 2 and vice versa.
This sets the depth (or width) of the rotary speaker effect.
High settings will give a wide left-right sweep, lower settings
will give a narrower sweep.
This parameter sets which of the speeds will be the ‘initial’
speed when you select this effect. It also allows you to listen
to the speed parameter you may be adjusting. For example,
when setting speed 1, select and when setting
speed 2, select . This allows you to set up rotary
speaker effects without having a MIDI controller to hand.
You may switch between the two speeds using any of the 128 MIDI controllers. This is set
under the parameters.
This selects which MIDI controller will trigger the change from
SPEED1 to SPEED2 and vice versa. You may select any of
the 128 MIDI controllers.
NOTE: If using MODWHEEL, make sure that this is not used to introduce vibrato to the sound
as well otherwise, as you change the rotary speaker speed, you will also increase/decrease
vibrato which may or may not be desirable.
