I've got a 1GHz/640MB iBook running Tiger. I've done plenty of recording with GarageBand 2 and my Tascam US-122 interface. Now, with my friend's Presonus Firepod, I've been trying to run Cubase, but I get tons of crackles and pops, as if the CPU were being hit hard. The VST CPU meter shows nothing over 20%, however. Plus, this seems to happen when I apply real-time FX, such as compression or EQing, to the channels. Here's the weird thing: it only happens when the FirePod is connected. I can mix multiple channels with real-time FX when the FP is disconnected. Also, i can record along with pre-recorded multi-track stuff with my 2-channel Tascam. No problem. Is it a Cubase issue, a Firepod issue or a CPU issue? Help!
