But I have a couple of Sp-404 questions...
I understand that each midi number controls a different pad as shown in the manual. But is it just the sample button or can it be the pattern button? In other words... If the pattern select button is lit will my MIDI commands control the patterns or will it still just control the buttons of individual samples?
On a side note: Is this a good investment? I want to be able to control various progressions through my samples while playing guitar. I have been developing this fuzzy beat driven folk songs and really want to start working on my live act. Is this the way I should go? Is there a better product? I have just been thinking about not wearing shoes on the stage and using my toes to hit the pattern buttons.... But maybe not.
