I\'ve attached a reply to problems like yours by Kevin Phelan from Nemesys - It was on the Yahoo Giga forum.
You should also search on these NS forums for posts by \'Hancor\' as he has a Logic/Giga system working well. He\'s an experienced PC head though and it doesn\'t seem like a total breeze to me who\'s always used hardware modules in the past.
Here you go:
It appears that Logic and Gigastudio are both fighting over the Mixtreme\'s 16
audio channels. This will happen even when
Gigastudio isn\'t actually running.
Gigastudio allows you to enable or disable each individual audio channel on the
Logic allows you to specify the *maximum number* of channels you would like to
enable on the card.
So take the following steps:
1) Run Gigastudio. On the Settings->Hardware/Routing page disable all audio
output channels. Enable channels 15 and 16.
2) While Gigastudio is running, start Logic Audio. In the second Audio Drivers
settings page, under ASIO choose \"Max I/O streams\"
of 14 IN and 14 OUT. Then enable ASIO and relaunch Logic.
Assuming both programs exit correctly and save their settings, it should now be
possible to start either program or both at the
same time without crashes.
* This assumes that the user wants to reserve 14 channels for Logic Audio and 2
channels for Giga. Of course you can change
this. Just remember that Logic takes over a range of channels from 1 up to the
max you specify. Logic ignores channels above
this max. You can assign these extra channels to Giga or to another app.
* Gigastudio 2.01.36 is a necessary update for this setup to work, because
previous versions of Gigastudio wouldn\'t let you change
the sample depth from 24 bits to 16 bits. Plus some problems with Logic
integration have been addressed.
Here\'s a recent post by Hans (Hancor). He seems to have success. There is another post somewhere where he details what he did to get things working. Sorry I haven;t time right now to find it:
My colleague Rob, is currently working on a song with 24 audio, 20 MIDI tracks and about a dozen Logic Audio FX at 16bit, 44.1Khz resolution. The hardware is on a Tyan S1837 UANG motherboard with and Intel PIII 850Mhz CPU. So far the CPU usage in Logic is hovering around 20%, while disk usage is about 5%. When sampling GS160 into Logic Audio we\'ve set the polyphony to 160;
and done it a track at time into Logic. We haven\'t yet found a need to run more. When applying FX one can either run the GS160 FX or the audio FX in Logic. If you layer on 32bit plugins the danger is to swamp the CPU
floating point register with data. IE. 2exp(32)= 4.3 billion samples to recreate the sine wave!!! So if you are in the habit of running 32bit plugins use them judiciously.
On the other hand in a few years time when IBM rolls out their 210GHz transistor technology this will merely be an academic matter.
