Note sure about the VX90, but i have owned two bass stations, and i both loved and hated them. Stunning bass noises, but forget about giving the damn things any sysex or more than 2 controller messages a year. On the positive side there is a freeware software front end out there for the bass station that you can use to store patches, they only hold 8 or 9 user presets and both mine seemed to take great delight in losing them just at the wrong time...
