Qu‑Bit Surface
Physical modelling can mean anything from the emulation of string or wind instruments to acoustic drums. Qu‑Bit’s Surface collects together several percussive‑style physical modelling algorithms in one 10HP module.
There are seven different digital models to choose from: Pluck, Bell, E Piano 1, E Piano 2, Kick, Snare and Prepared Piano. Each model has three parameters that can be tweaked, Strike, Tone and Decay.
Qu‑Bit Surface: 10HP, +12V 60mA, ‑12V 60mA.Decay is self‑explanatory, the range being dependant on the selected model. Strike tends to have a sonic effect which might relate to velocity, and Tone will depend on the model. For example, in the Pluck model (a plucked string algorithm) the Tone control adjusts the brightness of the sound, as you would expect. In the Bell model, however, it selects between four different sub‑algorithms, Vibraphone, Steel Drum, Bayan Tabla and Dahina Tabla (not really bells, but no matter).
