The instrument
Midi Bass plays sounds that come from audio information stored in EPROMs. Each EPROM contains the sound of one particular instrument, and up to four different EPROMs can be plugged into Midi Base at once. 360 Systems has bass sounds available for Midi Bass, with many new and unusual sounds are being developed, from synths to percussion to special effects.
Although it is used primarily for “bass” instruments, Midi Bass is actually capable of an audio bandwidth of 16 Hz to 16,000 Hz. It uses a circuit design with two VLSI (Very Large Scale Integration) chips to provide many features. (Source: Synth db)
