One Hour Compo celebrates it's 400th round on Thursday June 9th at 9:00PM EST! Don't miss it!

Compo is a slang word for "composition competition" commonly used by the arrangement community. It is derrived from the demoscene competitions by the same name. Contrary to this, compos are less of a competition and more of an excerise in composition abilites. Each compo has it's own unique format and guidelines and while some are as short as 1 hour, others can last anywhere from a month, to a few months. It's important to remember that the primary purpose of compos are to hone your skills and abilites by working within, sometimes very constricting, guidelines. These techiniques have proven essential to the growth of countless musicians.

Remember: the only way to lose a compo, is to not participate.

"Hate to kind of throw out a similar sounding theme, but I was thinking some Butter Building might be good track to not only mix but attract a little more people since people are probably going to be a bit more familiar with this source."

Source: Front Mission 3 - Front Line Base (PS1)


Don't forget to pay attention to the poll that I started in the Ocremix Topic!!


"Ever wondered what Final Fantasy Tactics set in a distant future, with giant mechs instead of knights, would look like? Wonder no more! Front Mission is yet another T-RPG masterpiece by Squaresoft. ...well, WAS since the serie fell prey to western-washing and vanished over night in 2010. "Front Line Base" from Front Mission 3 is a special song for me, as this is technically the first game tune I ever remixed. Ok, not exactly, since back then I didn't know anything about arranging or the VGM scene, so I just added drums on top of the original sampled tune and called it a day. Yeah, sorry 'bout that. Anyway, this source got a straightforward time-sig, simple yet distinct progressions and some interesting solo leads, making it easy to expand on. Hope y'all have some fun with this one! (^_^ )"
