Budding Stevie Wonders with GarageBand, listen up: the superb
but free Ticky Clav physical-modeled Hohner Clavinet synth is now on X,
as the Apulsoft continues to bring
the best VSTs to OS X's AU format. The instrument's physical modeling
features allow it to "faithfully reproduce the strings vibration and
the 2 pickups of the Clavinet Model C."
