Alesis IO|2 Interface on Mac Problem

Apr 27 2006 | 5:43 pm


It’s showing up in Audio Midi Setup, but the input gains are down – and faded out , so I can’t pull them up.

Does anybody know why this is happening ?

This is also the case with MOTU interfaces, you can’t change their in
and out levels from the Audio MIDI setup (but the cards work fine). So
this may be a normal behavior for Alesis stuff too…

I also have a Motu 828 on my computer, so I had a peak: thanks Patrick, you’re quite right, and the faders are down there too, but I get sound in and out, so obviously the faders greyed out and down is not the reason why I’m getting no audio into max on theother computer.

The other computer, a mac mini, is not mine, but since the guy bought it because I told him my software would be better for him than a hardware phrase sampler, I feel sort of obliged to get this sorted for him :-)

Any other comments received most gratefully,

As it is an Alesis interface…
I recently tried during a couple of hours an Alesis photonX25 with a
Mac (OSX.3.9 and OSX.4). I first had no sound neither, until I changed
the vector sizes in Max/MSP (I don’t remembered what I did, I just
changed the settings a couple of times, for both signal and i/o
vectors). I must admit that I didn’t try this interface with other
software than Max/Msp (even not the Finder).

Good luck

Which of course is a good idea and…

Audio in and out both work with Garage Band. Thanks Patrick, that’s nailed it down a bit.

Audio works on the computer/interface on which the application was developed, but not on another computer (same model) with a different interface.

Any guesses ?
