SAMPLE APPLICATIONS MIDI KEYBOARD PERFORMANCE SYSTEM In this system the SPX90 is connected immediately following a MIDI keyboard, and its output feeds either an instrument amplifier or sound reinforcement mixing console. The MIDI OUT terminal of the keyboard is connected to the MIDI IN terminal of the SPX90, permitting automatic selection of different effects programs for specific voices selected at the keyboard. The SPX90 is under direct control of the keyboard player (rather than the mixing engineer) so he can produce exactly the effects he wants for each voice or musical selection. In a multi-keyboard system the SPX90 could be patched into the effects loop of the keyboard mixer. The MIDI keyboards could be chained together via the MIDI THRU terminals (MIDI OUT -+ MIDI IN -+ MIDI THRU -+ MIDI IN -4 MIDI THRU with the SPX90 MIDI IN terminated from the MIDI THRU terminal of the last keyboard in the chain. This way, all keyboards in the system could be used for MIDI effect selection.

BASIC SOUND REINFORCEMENT SYSTEM The SPX90 is an excellent addition to the small to medium size sound reinforcement system. Its input can be fed from either a mono effects send or auxiliary send bus on the mixing console, and its stereo outputs can be fed back to the corresponding effects or auxiliary return inputs on the console. Assuming the console used has independent effects or auxiliary send level controls on each input channel, it is possible to add the required amount of SPX90 effect to each input. It is also possible to use two SPX90 units for full-stereo reverb and effects in a larger system.
