Tom Sivak asked: >>>> I copied an offset chart for EBVT posted some time ago and have been using it happily with RCT for about a year. It produces a pleasing temperament with just enough color to make it interesting. I am very happy with the results, but... Hoping to improve my product I went to Bill Bremmer's web site and copied the temperament sequence to tune it aurally and found that the RCT offset I've been using is not correct. F-A, G-B, and C-E should all beat equally, and this offset chart consistently produces a C-E which is faster than the other two. Does any one have an offset chart for EBVT.... <<<< Tom, the offsets that you posted are quite a bit different from the ones that I figured out a while ago. Here is my best guess: C 6.24 C# .71 D 2.07 D# 1.95 E -1.07 F 4.32 F# -1.24 G 6.31 G# 2.77 A 0 A# 2.15 B 1.01 Note that this is not exactly what is found in TuneLab because the TuneLab version is shifted so the average offset is zero, whereas I have shifted the above chart in accord with the more common convention where the offset for A is zero. The chart shown is therefore high on average by 2.10 cents. The offsets were calculated by following Bill's aural instructions as applied to a software simulation of a tuning, where average inharmonicity is assumed. -Robert Scott Real-Time Specialties
