Send me the tuning instructions and I can convert them to offsets for you. /Jason Kanter <div>On 1/18/07, Thomas Cole <<a href="mailto:tcole@cruzio.com">tcole@cruzio.com</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Dear historical temperament mavens, I've been asked to tune a "tack" piano according to Lou Harrison's instructions (Cinna, 1955). The schema calls for tuning intervals as ratios and I'd like to know if there is a way to convert these fractional numbers to offsets. I have only a short window of time on stage (Sat, 1/20) and it would be very easy to do if I can use RCT. Tom Cole </blockquote></div> -- =cell 425 830 1561=
