Disklavier

Greetings david962548,

you may be able to do all of this, without a sequencer if you look at
a text dump of a MIDI file and figure out what is where and where it
needs to be. STD MIDI files have percussion on channel 10 so you need
to deal with this. Ideally you should have a sequencer program so you
can play the file, hear it and determine what voices you want to keep
and what you want to do with them. In most cases you will
(understandably) give up and move on to the next file.

MIDI is just a format. You can do anything with it and you will find
just about anything on the internet. Don't expect to turn some random
found stuff that someone else assembled and turn it in to just what
you want, with little effort. Would you expect to find some rambling
prose written by Joe Smith and turn it into Shakespear with a computer
program?
