Doing my annual winter recording stuff. IBook G4 (V 10.3.9, 1.07 Ghz, 768 MB SDRAM) with an iMic w. Garageband V. 1.1.0 (26). Having my typical "freeze up" during recording, keep fiddling with settings to try to keep it running with my minimal processor speed. I'm somewhat familiar with Garageband preference settings. A few questions: 1) I turn off all programs. Will turning off Airport also help? 2) I have a Lacie 160 Gb hard drive. I tried running Garageband on that but it didn't seem to help. Should it? 3) Last night it "froze" again during recording. I fiddled with it, got it to play again, could get input signal in via iMic but no output with headphones into iMic. Yep, all audio input & output selections were OK. I could get sound output via the headphone jack in my iBook (after changing output setting), but not thru the iMic. Turned Garageband off/on, no help. Tried the Lacie, no help. Turned the computer off and today got output thru the iMic again. Ideas? 4) I often find my "Saved Instruments" have turned off effects when recalled, especially AU stuff like Matrix Reverb, Delay. Forces me to put long lables on instruments just to remember what the heck I had in 'em. Ideas? 4) I fiddle with voices to select fewest, even turn off amp sim and other stuff in tracks while recording, still freezes on me. Sometimes freezes on track two or three, sometimes later. No rhyme or reason I can see. Other ideas? 5) Was thinking of getting a better interface, but after looking into it concluded I'll compound my problems as newer ones require even greater processor speed. Correct? I'm probably stretching the iBook G4 beyond it's limits. Any help with any question appreciated.
