Well I find it unfair most of us struggle to find tracker instruments, and other tracker difficulties, while you use some in-browser tool that automatically gives you your sounds.
wait what even no that what
"unfair"?
it's a convenience of technology, we chose to use more complicated trackers on our own accord so putting up with a lack of decent intruments is something we have to get good at to make better songs.
if you ask me, beepbox is limited in its own ways, and i doubt darksaber's got it any easier than us.
though this brings up an idea, maybe you should add to the application a section where you mention the program(s) you intend to use/are using?
