00700	Dear Mario,
00800	
00900		I suppose by now you wonder whatever happened to me.  My autumn plans were rather
01000	turned about and when I got back to Stanford I became involved in all sorts of unexpected
01100	and time consuming projects.  I have made many improvements in my computer music
01200	printing system.  I've enclosed some examples for your inspection.  The INVENTIO
01300	SEPTIMA by Bonporti is my latest San Andreas Press publication.  I got a nice review
01400	of my Woodwind Trio publication in the Music Library Assosiation bulletin, NOTES.
01500	I have also enclosed this for you.
01600		The single pages of music include the first pages of Cowell's "Romantic"
01700	QUARTET and Ligeti's SAN FRANCISCO POLYPHONY.  I did the Cowell just to show
01800	the capability of my system to handle unusual rhythmic units.  All the spacing
01900	in this example was done automatically by the computer.  The clearest copy is
02000	a direct Xerox output from the computer and the darker copy (too dark) is a
02100	photo litho copy of a felt pen copy made by the computer's plotter.
02200		The Ligeti page shows how I can handle mammoth orchestrations.  The
02300	page was assembled from 14 separate units and then drawn on the plotter as
02400	a single unit with consistent spacing in all parts.  The final prints were
02500	made by a high-quality photo litho process that required making three negatives
02600	which were then pieced together.  This last was necessary because my original
02700	page was too large for the photo copy system.  The final reduction was to
02800	about 25%.  This size was chosen to fit the standard 11x17 paper.  The total
02900	cost at the print shop - for the photography, plate, paper and printing 100
03000	copies was about $20.  My time on the computer was about 6 hours.  I think if
03100	I were to do the rest of the score the pages would average about 4 or 5 hours
03200	each.
03300		Currently I am working on the innards of my program to improve computer
03400	efficiency.  The actual computer time (not human time) involved in this work
03500	is figured in minutes and seconds.  The Cowell page takes about 30 seconds of computer time
03600	to produce a Xerox proof and about 2 minutes to produce a master sheet for
03700	publication.
