Cheers guys, that's what I was hoping to hear.
Tough to say how many I'll need ever. I'm not planning (but who knows right?) to record an orchestra, just a rock/alt band. I guess that would be 16-24 if I really tried to fill them but I'd most likely not need more than 8 for a while yet.
To be honest, rather than me answering that question it prompts me to ask another - how many tracks do people use when mixing say a 5 piece band? I would reckon on 1 mic lead singer, another mic for others to sing, 2 x guitar, bass, 4-7 for drums (unless it's Mr Bozzio he he) and another few for extra things, samples etc. I make that about 16, could stretch towards 20. What is the experience of others?
Perhaps a few more for doubling vocals/guitars (which is somthing I have seen people talk about here)? The 32 you use is starting to look like a good number if so.
