(F) Auto Pan and Tremolo

Both these effect programs are very similar. The Pan effect is really nothing more than two combined Trem-

olo effects that work against each other. The Auto Pan is primarily set with the “Direction” and “LFO Freq”

parameters. The Tremolo effect even offers Pitch Modulation (compare this with Pitch LFO – Analogue

Workshop). First and foremost you will use the “AM Depth” function which is responsible for Volume modula-

tion, i.e. Tremolo.

EXAMPLE:

You will find two different E-Piano sounds in the Tutorial Performance bank. Using the first example (TP110), experiment

with various “Direction” settings. Here the developers demonstrated their meticulous attention to detail. The Tremolo

effect is very pronounced in the second E-Piano (TP111). For a change of scenery take a good look at the Pitch Modula-

tion as well. Of course you can also use this effect simply as an additional LFO.

(G) Rotary Speaker

The Rotary Speaker (Leslie effect) is based on the Doppler effect. It is primarily used to liven up organ

sounds through the periodic varying of pitch as well as volume and tonal color that arise when a loudspeaker

is rotated. Common are two rotation speeds: the slow setting (Slow Leslie) gives a kind of cathedral effect,

similar to a floating Chorus effect. In contrast, a vibrating, spinning soundscape is produced by fast rotation

(Fast Leslie). The increase/decrease between these two speeds are a great tool for creating musical tension.

EXAMPLE:

A slow Leslie organ can be found in Tutorial Bank memory location 112. As this example demonstrates, a medium value

for both the “LFO Depth” and “Dry/Wet” parameters fares well. You determine the rotary speed with the “LFO Fq” func-

tion, which initially is set to 0,63Hz. Knob4 (Assign1=VariCntrl). It is used to control the speed in real-time and helps to

play your organ authentically. With this in mind, take a look at the section “Controlling Correctly”. It goes without saying

that the Leslie effect can be used for sounds other than organs. To prove the point, listen to a synth bass sound (TP113).
