After having tried to make melody lines for lyrics, I was thinking it would be nice to be able to insert words into the pattern editor, as a reminder marker of what word should start being sung.
I imagined having two tracks next to each other, one with a plain synth sound of the melody I want the singer to sing, and the other have words of the lyric.
That way you could also easily make a karaoke app, which also would be helpful for a singer. Actually if you make the Renoise stuff then I guarantee I make the karaoke app, deal?
