Gregjazz has released a freeware Hardwood Clave VSTi. Greg thought there were too many unrealistic clave samples out there, so he decided to sample his own.
The GUI presents Clave patterns and has only 2 knobs, one for the Mic position and one for Rhythmic Variation, which adds humanizing delay to the notes.
The Hardwood Clave VSTi is not yet on Greg’s website so you can download it here. You will also need this soundfont.
