01200	Dear Mr. Anderson,
01300	.begin fill adjust
01400		Enclosed you will find a few copies of the first page of your
01500	INTERMEZZO  as printed by my music graphics program.  This turned out
01600	to be a somewhat more difficult page to set up than most  I've  dealt
01700	with.    This  is because of the very active inner parts.  (Orchestra
01800	scores are usually easier to set up.) You may note that measure 10 is
01900	the  same  as  measure  6.  In this case I simply copied the data for
02000	measure 6 into the new position.  Thus only the new material  on  the
02100	third  line  had to be typed in.  Actually I could have done the same
02200	kind of thing for some of the other measures too.
02300	
02400		I have enclosed listings of the basic input data for each  of
02500	the  lines.  These lists probably aren't too comprehensible without a
02600	detailed explanation. Also I have enclosed  the  parameter  data  for
02700	line  2  of  the  music  which  the program generated internally.  In
02800	general the list of numbers after each word gives  information  about
02900	the  vertical  and  horizantal position of the item, its size and all
03000	sorts of things like the number of tails on notes,  the  accidentals,
03100	dots,  stem  direction  and length, etc., etc.  For the most part the
03200	operator doesn't have to bother about all these numbers  except  when
03300	making some of the finer adjustments of positions.
03400	
03500		The actual program that processes all this data is written in
03600	a combination of FORTRAN and PDP10 machine language and occupies over
03700	a  100  pages.  The program is "modular" so if it is to be translated
03800	for use on a mini-computer system, such as a PDP10 or NOVA system, it
03900	could  be  broken  down  into  reasonably  sized  separate  units.  I
04000	believe  that I could make all this work on a  mini-system with 32000
04100	words  of memory and a good graphics display system.  About two years
04200	ago my cost estimate was around $150,000 for a complete system  which
04300	would  allow  a certain amount of time-sharing.  At this date I think
04400	the system could be put together for under $100,000.  Of course  this
04500	is  still  a  lot  of  money, but perhaps a group of publishers could
04600	finance it.
04700	
04800		I hope this information will be of use to you.
