For tube-amp distortion for rhythm guitar, turn

up the Drive control. This will give a warm dis-

tortion similar to classic tube amplifier / bass

speaker cabinet combinations.

Keyboard sounds

The RPM-1 sounds great on a variety of key-

board sounds, especially when used on a mixer

FX send so that you can blend the RPM-1 sound

with the direct sound. A touch of distortion will

enhance the realism of electric piano sounds,

and the cabinet emulation simulates the built in

speakers of popular electric pianos. Sampled

piano sounds through the RPM-1 with Drive at

11 o'clock, Horn Speed at 8 o'clock and Balance

at about 1 o'clock can create a convincing

"reed" electric piano. With Drive at 8 o'clock,

and Balance closer to 12:00, you can get a com-

pressed, bell-like piano sound. The cabinet

emulation will round out and warm up any

sound you put through it, so try the RPM-1 with

the Brake engaged even when you don't want a

rotating speaker effect. The cabinet emulation

has a definite personality to its frequency

response, so "realistic" sampled sounds and

sounds with lots of high frequency content can

be altered, sometimes dramatically. You can

experiment with it; try doubling the RPM-1

sound with the straight sound, both for solo

instruments and for pad sounds. Turn off any

distortion, delay, chorusing or modulation in the

instrument to feed the RPM-1 a clean sound.

Organ

For best results, make sure that your organ

sound input is as pure as possible. Whether you

are using a combo organ, synthesizer, sound

module or tone-wheel organ, turn off any dis-

tortion, delay, chorusing or modulation in the

instrument. The best sound is achieved by let-

ting the RPM-1 add the rotating speaker emula-

tion to a clean organ sound. You can add

reverb or delay with an external effects device

placed after the RPM-1 in the audio chain, or

through an effects send on your mixer.

Organists will often change the timbre of their

sound by pushing in and pulling out the draw-

bars on their instrument while they are playing.

This emphasizes certain frequencies of their

sound over others. If you are not using an

organ with drawbars, you can twist the RPM-1

Balance control to get a variation in tone while

you are playing.

What is a rotary speaker?

A rotating speaker cabinet consists of a high frequency compression

driver and a low frequency speaker, whose sound is directed through

mechanical deflectors spun by motors. The motors can be switched

between stop, slow and fast rotation speed.

The horn and the rotor create a directional beam of sound, and as

they spin, this sound beam is swept around 360°. The sound is always

moving in relation to the listener, creating pitch (Doppler) shifts, vol-

ume variation, and constantly changing, complex reflections from the

inside of the cabinet and the surrounding objects.
