Topic: 3 RME Madi/192 channels into Logic Pro plus Apogee Symphony

Hi,

I work for a composer here in Los Angeles. We are currently running 2 RME Raydats and a sync card with an Apogee Symphony. Using the Apple aggregate driver we get about 90 or so channels of I/O. Things work good.

We are considering using 3 RME Madi cards and with the Symphony's 16 channels of I/O we would have 208 channels of I/O.

Q: Has anybody done this with Logic on a current 12 core 3.x GHz Mac Pro? Are there any things we need to look out for? Any assistance or experience one can offer would be very welcome, since this would cost us many thousands of $$$ to do this upgrade.

Hi George, have you seen the MADI FX card? 3x MADI I/O in one PCIe card.

Re: 3 RME Madi/192 channels into Logic Pro plus Apogee Symphony

Hi Jeff, No I haven't.

Here's our issue... We know Logic uses 1 core for realtime I/O monitoring, as well as DSP for any internal busses being used for reverb, etc. We are already having issues with 2 raydat cards (4x8 channels each, or 16 stereo pairs for a total of 32 inputs). Using the Madi cards we would almost quadruple our current input loads.

We can't find a single Logic Pro user who is doing this and can confirm that it will actually work the way we need it to work. The issue isn't your Madi cards, it's Logic and its inability to spread the load out like it does with VI's or even VEPro, which also spreads it's use out over all the available cores in the main Mac Pro.

Do you know any Logic Pro users who do this that we can talk to, see how well it works, how they are using the system, and get a few answers before we invest a small fortune in cards and days of reconfiguring a system that might nowt work in the end?

Thanks for your earlier answer...
