Bob, we had a chapter meeting, about 1985, at the New England Digital
Corporation when it was still located in White River Junction, VT. I believe
the company has now moved to New Hamshire. At that time Robinson come up to do a class on
voicing. He worked on both the strings and
the hammers. At that time New England Digital had a computer system they called
The Synclavier. Using their equipment was fascinating. As Chris did various
voicing techniques they were able to print out the results of his efforts.
This they could do both graphically and in spreadsheet form.
The graph, using an XYZ coordinate system was able to graph the multiple
harmonics produced by any note and show it in elapsed time. They were able to
sample and analyze quite nts of time. It was f
They were able to sample and analyze quite a few partials for differing amounts
of time. It was fascinating to see how voicing could change the relative
volume (or amplitude) of the partials relative to each other. The system
was able very well to display the decay and building up of the various partials
as the note was sustained.\
After this session, I believe Chris bought some form of frequency
analyzing equipment so that he continue to research this techniaue.
Somewhere in my stacks I have some of the original graphs and
spreadsheets that were produced that day. If you would like to see them, I
shall try to locate them and send you some copies.
My guess is that someone else will also jump on this thread and tell us
that there is a program that already does this for home computers too.
Our best to you and Marcia. Emily and I will look for you in Dearborn!
