These programmes are not tested by Musonix.co.uk for being
any more or less suitable to use with the books, except that
they are respectably open-source & free. Open source sequencers
are freeware with the advantage over other free download programs
that volunteers might add pieces of code and keep them updated.
To digress, there may also be old office computers available
free on Freeycle.org
(uk)

Windows & Cross-platform midi sequencers
MidiSwing
Jazz
Jazz++ not
yet stable; volunteer help welcome
Frinika
Anvil: not open source;
base is free
Other smaller or less well-known programmes are often cheap or
free: chose the "sort by: freeware" option
to download from the tucows sofware download site.
Linux users have the widest sequencer choice including
Anthem
Mac midi sequencers
MidiSwing
Mac users may also have a Garageband sequencer as part of the
cheap iLife package or occasionally sold separately. Apple likes
to offer free training & indocrination through its dealers,
and in the USA this runs as far as free lessons in Garageband
by way of product demonstrations once a week with six topics
demonstrated six-weekly. Worth checking if interested. At the
last check there was no sign of free UK training sessions.
Please feedback
