E-mu Audity 2000
This crazy synthesizer can be programmed and tweaked to create some of the most far out sounds that we heard in the 90s. The Audity can layer up to four sounds, create loops and arpeggios, soft pads, harsh lead synth tones, and even electronic drum samples. You can get lost for hours tweaking filters and MIDI parameters. My favorite use of the Audity is programming complex loops to create a musical bed or add texture to the mix. The most notable electronic artist to user this synthesizer is Crystal Method. It is a one space rack mount unit that has a multiple stereo outputs as well as MIDI in, out, and through.
