MIDI volume software MIDIFixer lets you edit volume levels and more.

MIDIFixer is a program that lets you modify the volume and dynamic range of a MIDI file, eliminate stuck notes, and modify the speed. MIDI files may play too quiet to hear in some spots and too loud in other spots. MIDIFixer will help you smooth out the volume levels in a MIDI file. The velocity of each note is updated automatically. Track velocities are updated also. MIDIFixer can fix annoying stuck notes. Have you ever encountered a MIDI file that has certain notes that stick on and never turn back off? A single stuck note can completely ruin an otherwise good MIDI file. Using a brute force technique, MIDIFixer can insert extra commands into a MIDI file that instruct each note to be released before it is used again. Are you having trouble playing along with a MIDI file that is too fast? Or do you want to speed it up for more excitement? MIDIFixer can slow down or speed up a MIDI file.
