I've come to conclusion that sound editors/composers made for AGI are either hard to use or incomplete.
Therefore I rather use real composing software (e.g. trackers) and then convert my products to AGI. But unfortunately one has to use many programs to convert if not using it2agi(shoo shoo Impulse Tracker!). And result ain't best when song has gone through 3-4 different apps..assuming that you can call it a song after that..
So, if anyone with programming skills would like to ease creating music & sounds for AGI, don't create new fancy editor and waste eternity to interface and all that, create a convertor which converts (popular) sound-formats like midi, xm and mod STRAIGHT to AGI and you've definetely left your sign to history of AGI.
I have spoken.
