It should be - but it still isn't!
Here is, what iZotope wrote to me this summer:
"Unfortunately this feature in Relay is a bit dependent on the DAW you are using and may not work on across all DAWs."
They apologized for the inconvenience but more helpful would have been to inform customers about what iZotope-products are unable to do - BEFORE the purchase! For me the feature was the biggest arguments to spend so much money on a mixing software. Disappointing!
I asked them if they are planing to add the feature soon so that even Windows-users can benefit from it.
Here is, what they answered:
"It is something we are hoping to add for a future patch, but unfortunately part of it has to do with the way Studio One's plug-in wrappers work which is why it differs so much based on the DAW used."
I think it's a very diplomatic wording for "We do not plan to add the feature at all!"
Now its your turn PreSonus!!!! Team up with iZotope and prevent people from switching the DAW!!!
