SUITABILITY/PERFORMANCE
is not charging too much, even on small config. no problem so this cot
OVERALL OPINION
4 months of use of different versions. the app is stable, sound is honest, clean, B4 is not, but it's still very nice. Note that ZR-3 is a more complex version, with the different registers of the organ, and its largest, and since I tried it I have a little abandoned ZR-1. the url of the original site: http://rumpelrausch.de.vu/
for résumé for free and without arriving at the native instrument, it's still very good, and the only free in its category. but go straight to the ZR-3!
