I've tried using various soundfonts. even some free VST plugins. let me know!
Soundfonts have very low sound quality, and free VSTs in most cases also.
He uses some pretty large VST with various effects like reverb or eq. Either he digitally records the sound of his piano instead of vst.
Peter told me he was using a real grand piano that has a midi output. So the charming sound is a real piano and not a VST instrument.
