Yes, this is a genuine Java melody editor which, unlike my original
allows you to work with up to seven voices simultaneously. You can
draw your own waveforms and envelopes for each voice, you can browse
through a set of pre-constructed melodies and you can even
save your work for later use.
You might want to visit the instructions page.
