Hi, Just thought I'd say hello as a new PS-04 owner.
I know it's been obsolete for a few years but I'm really impressed with my second hand fleabay purchase. Knowing almost nothing about multitrack recording the manual seems pretty mind-boggling but so far I've managed to record two tracks, each with guitar and effects. Doesn't sound much but it's taken me three days and I haven't even thought about mixing yet!
Anyway, I've been helped hugely by reading all the the great tips here and I've been amazed by the quality of the music you guys come up with.
