Working On Logic / Battery, Frequent system errors Options

[zaaresh]

Hello there! I ´m glad I found a webpage dedicated to Music on Macintosh. Since Nov last year my prod partner and myself own a G4 ( 1999) , we use it with a cracked Logic until we will be able to invest more in software. Recently I bought NI´s Battery, which I believe has a very fine choice of drum sounds ( because real) . My Mac is a quite slow one, I think it´s around 450 Mhz (..) , and I had problems with getting started Battery . I downloaded an upgrade from the NI page and the Stand Alone program worked fine, but it´s impossible to launch LOGIC and use Battery as a VST PLUG and MIDI application - the most frequent error is error 1 or erroe 2 ( RAM Memory?) .
So I have a few ( probably beginner) questions:

1. As Logic is a cracked 4.8 version, is it probable that it won´t accept Battery?
2. If I run about 8 tracks and put about 3 WAVE compressors and 3 WAVE Reverbs in total, the system is overloaded: is this because of the cracked version or is it the computer speed?
3. What can I do to optimize my Mac? Is it worth to buy Mhz extensions, or would a quicker hard disk do the same job? (The idea is to get a quick external firewire disk)

Can anyone help? I would be glad if yes! Thanks , milosz
