This will undoubtedly seem like a silly question, but I'm a silly guy so that's OK.
What I'm wondering is: if you are creating an ambient track that is mostly going to consist of one or more swirly pads with some melodic business on top, etc... How do you record the different steps?
It almost seems like you would have to decide at the outset that "I want this to be 5 minutes long" or "twelve minutes long." Do you just pick a length and start recording while holding down your pad for 6 minutes (or copy and paste a section, whatevs...) and then go back and record the next layer (melody or bass)?
There is a video linked on here of someone showing how to use the OP-1 to make some ambient music and it sounded wonderful but it was only about 20 seconds or so. How would you translate that up to a full song?
Thanks in advance,
