Microtonal Tuning...

Hello,

I also asked this question on the harpsichord list, but thought I
should ask you too... I am looking to perform a piece in 12ET, that has
the two manual of the harpsichord tuned a quarter-step different (lower I
think). I don't have any tuning equipment and have always tuned by ear,
does anyone have any suggestions on how I should go about this.
Also, I am looking to add some mean-tone pieces to my harpsichord
recital if any one has any suggestions, or works of their own that they
would liked performed that would be great.

Thanks,
