Oberheim (Viscount) OB5 Organ

The Oberheim OB5, a dual-manual Hammond B3 simulator. The OB5 has 91 digital generators, each dedicated to producing a single pitch. Mixing the drawbars produces spectral, rather than harmonic, combinations (a feature true to the original B3). Designers strove to mimic the inherent imperfections found on the B3. For instance, when percussion is applied to the attack of the tone, the percussive sound doesn't trigger on every note when many notes are played in quick succession.
