I am very very happy with the Xylosynth. It has also proven live in different ensembles (duo, combo and big band). For me it runs on a Macbook Air with Main Stage and GarageBand.- Wilfried Bokelmann
See Robert playing his folding 4 Octave Bubinga Xylosynth with his fabulous Ecoustic band here. You can spot the Xylosynth at 1.20 minutes.
