A speaker cabinet designed by Don Leslie, who also invented less useful things like 3D movies and missile guidance systems. A Leslie speaker system splits the sound into low and high frequencies, sending the low frequencies to a woofer speaker and the high ones to a tweeter speaker. Each speaker points at a horn to direct the sound, and the horns are connected to a motors that make them rotate. The sound gets thrown around in circles, giving a tremolo effect because of the Doppler effect. The Leslie effect is very difficult to duplicate on a synthesizer as a Leslie is actually a physical system that depends on the cabinet's shape and the room in which it is placed — you would need to be physically present in a room with an actual Leslie speaker to experience the full effect.


A voice when it is being used inside a performance.


A programmed combination of voices. Performances can be splits, which divide the keyboard in two regions, FIXME.

See Also part, voice.


Performance type in which the keyboard is divided in two sections. Each section usually plays one instrument. For example, the keyboard can be split to play an electric bass sound on the lower register and a piano sound on the upper register.

Roughly, an instrument definition. Each voice is composed of up to four elements, where each element is a waveform plus a number of effects. A common effect is to make elements fade in or out depending on key velocity. For example, you could make an instrument that sounds like a soft pad when you press the keys lightly, and sounds like a strong bell when you press the keys harder.
