Most of these midi files are the result of my producing practice tapes
for members of the Ashburton Singers for works we are rehearsing, or
for other choral occasions in which I have been involved, such as Choral
workshop weekends at Dartington Hall. All the files should have separate
tracks for the different parts (eg SATB), but not much in the way of
non-vocal musical lines, except where the instrumental or solo line
is absolutely essential to the choir parts for self-evident reasons.
Most of what we sing is scored for voices-only in any case.
N.B.
If you have a Windows PC and want to try your hand at manipulating these files so that (for example) your own part is more prominent than the others, then take a look at the MITSYN Score Editor program
