My Presonus Firestudio is no longer compatible with my computer. I have a Macbook Pro with Logic. I would like something with 2-4 channels that offers slightly higher quality than the Presonus without breaking the bank - this wasn't a planned purchase. I was looking at the Audient ID22 - has anyone used one of these? How would I add more preamps to it if I was looking to expand my input/output options for recording? Does anyone else have some affordable bang for the buck recommendations? At the moment, this will mostly be for recording a variety of guitars either mic'd up or through a POD HD500, and also for room mics for recording jamming with friends and as a Bass DI.
