PianoRollComposer is a MIDI sequencer for composing and playing music.
It uses the standard treble and bass clef staffs. Notes are displayed in the piano roll format, so it shows music with absolute accuracy. Notes are entered directly on the staffs, and you can edit each note to give it the exact characteristics you want.
You can use all 128 MIDI instruments and 61 [extended] MIDI percussion instruments. Windows will play them all. Up to 15 different instruments can show and play at the same time (think orchestra).If you have a MIDI keyboard, you can play and record any instrument with it, and you can add to existing music with it.
And if you're learning to play piano, it can help with playing exercises you can easily write, as well as with playing existing music.
