I am curious: has the mapping for the mutli-tenors changed with the new Sibelius template or the previous one? In Finale 2006, for example, tenor drum #1, R and L, was c and b-natural respectively. Now it seems to be b natural and b-flat respectively. I am using a midiman, Radium keyboard. Have I inadvertently changed a setting? Or this this a new mapping? I look forward to your responses.
I just checked this with the new template and it seems OK on my end. Here's my guess. You may have inadvertently transposed the layout of your Radium keyboard. I remember doing that a time or two on my oxygen 8. Do a ";reset"; on it, and let us know if that puts you back on track.
