|The E-MU 25 was a precursor to E-MU’s Modular systems, featuring about twenty modules behind a single front panel, including 3 VCO's, 2VCF's, 2VCA's and two envelope generators. Unlike the “bulletproof” all-aluminum standards of the Modular systems, the E-MU 25 used cheap slide pots and plastic switches, and even sported a "vacuum cleaner" power switch! Only two units were produced; they were identical on the outside, but had completely different circuitry inside because the circuitry was evolving so quickly.

||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.
||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
