"As long as you've tried, it's all good!" - Cibryll
She knows from experience, having made a few ORG songs in the past... most being edits of Cave Story (or beta) songs... but one or two original compositions... she tried, and that is good enough for her...
(One she made for me, included... not the best of songs, but it is the thought that counts, too...)
I'm actually using Audacity not ORGViewer (I might try that again some time in the future). Creating the songs basically involved me taking various music tracks and sampling them to create something new. Most of the music in Gun is from various games and few of them (e.g the stage themes for Between the Levels and Taboo Zone) are created by sampling. The latter won't be appearing as often due to how time consuming it can be.
Aside from that, the only original composition experience is via WarioWare DIY though only a few of the tracks aged well and the rest of them were pretty bad.
