MOXF here. Pianos and EPs are great, the Flash Board allows more waves to be added. Layers, splits, and editing easy ONCE you get the hang of Yamahas OS.
MOX Organs, thats where it fails and crashes.The rotary FX just doesn't cut it for one. You can assign the organs hard right and use a vent/burn etc but you have to disable the system and master FX because they default to stereo only and some of the LH panned voices will bleed through the FX into the organ output.
Also a lot of the voicings have percussion built into the wave with no way to edit them.
The VR09 is the choice for B3 even with the percussion going thru the C/V
Appreciate the feedback on MOXF. I think I will stay with VR-09 since it was the Hammond clone and twin roatary that I wanted most, along with transistor organ / drawbars. Thanks.
