Midi Maker is my favorite MIDI sequencer! You can get it here

http://www.necrocosm.com/apps/mm.zip

It's a trial which expires after 50 uses,but simply load MidiMaker.reg in2 the registry.
Then you will have all your uses back.This means you can use the trial 4ever!

The only limitations of it is that it can't make anything longer than 250 measures
or have a temp higher than 300.
