Yes, it is frustrating; with the current version 1.0 the styles cannot be adjusted and therefore the box cannot be used in a live situation.
A few days ago I reported the following bugs to the Swiss Hotline:
1. The bug as just described above.
2. The variation (A, B, C or D) is not saved in the registration. After the load of a registration, still that variation is active, that has been selected manually the last time.
3. The volume of (for example) the Lower 1 can be adjusted for each variation (A, B, C or D) and this works. Saved in the registration however is only the volume of variation A (if one saves a new registration). After the load of the registration the volume of variation B, C and D are back to factory settings.
4. If the volume of Drum 1 is changed for variation A, the same volume appears also for variation B, C and D.
5. The settings of the "Menue" are not saved at all in a registration (I know that the midi channels can be saved in the Power On Setup, but only the channels, not the Transpose RX/TX + the Dynamic Curve!). If this is not a bug, it is a design error, a serious one!
Aloha to Hawaii and enjoy the sun. We have got snow in the Swiss lowlands :-)
