technakhol: theres a homebrew program done by someone that do those 808/909. But its quite a simple one, cant really tweaked much. On psp, theres a psp rhythm homebrew(latest version

title which can do a better job and much more things in it. That one is quite fun also, can arrange entire songswith it and lotsa things to tweak plus lotsa sound files available online to play with.
hey sonic bro, i think i know why it didnt work.. i send you a pm, check it out, it should solve the problem.
