Hey, I've been trying to make a soundtrack for my game in Pulp, but all I can make is irritating sounds and grating sine waves. I've heard some really good chiptune music made with Pulp but I have no clue where to even get started.
It's a simple interface, but complexity and difficulty are not the same. You have to try messing around with the values a bit on each instrument.
Also, try using one to do chords, one to do a bass line, and one or two others just for the melody.
Finally, try to figure out what you're going to make ahead of time, because for some unknown reason, though it'll let you make about a minute of music, you can only edit the first 4 measures, meaning it becomes most efficient to put your song in backwards, section by section, copying each section to where it actually needs to be, and put the beginning in last, since the beginning is always able to edited.
You can move the window of the song panel to show any 4 measures anywhere on the timeline by grabbing the "Notes" bar near the top. Though I do agree it helps to work out the music beforehand!
