The Clavi D9 is based on the well known clavinet D6 by Hohner.
It is probably one of the most “funky” instruments ever invented, despite the fact that it was originally intended for classical music since its sound is close to that of the harpsichord. It turns out that it is very well suited to replace or double a rhythmic guitar and has been used in many Funk and Disco hits.
The clavinet has 5 octaves (60 keys) and works in a simple way. When you play a note, the string is pressed against a bridge just like a hammer on on a guitar, the non muted part of the string vibrates and the pickups amplify the sound.
The D6 has very few controls, 4 eq switches, 2 pickup switches and a global volume.
Acoustic Samples recorded both pickups and they modeled precisely the eqs, as a result you can use the whites switches just like on the real instrument.
They sampled every possible aspect of the instrument, normal notes, staccatos, releases, mutes, every pickup, sympathetic resonances to give you the most authentic Clavinet sound possible.
