Hello fellow MMDers, just got back from a field trip that netted me
an A-roll piano.  My previous experience has always been with 0-roll
orchestrions, and after searching my archives, have discovered that
I do not have an A-roll tracker bar scale of any kind.  Can any MMDers
help with obtaining one?

Thanks in advance,
