    Hi Patrice,

    Sadly we do not have any HDX interfaces in our office at the moment thus we won't be able to reproduce this issue right now.

    We've received other feedback regarding issues with HDX setups lately, so we'll try to get a permanent HDX unit in the office as quick as possible (to also make our plugin run on the DSP). Sadly at this point there is not much how we can help, most likely something is going wrong in the communication coming back from the DSP, but to reproduce this we'll need to wait until we get the HDX unit. 

    Our apologies for the inconvenience; we hope to test this for a fix soon!

    Thank you for your reply. It's because I had an afterthought that you may not have HDX at hand that I posted my message on the forum, so maybe other HDX users may jump in.

    The way Pro Tools works makes it so that it is better to have native plugins before dsp ones to avoid multiple round trips between the computer's cpu and hdx dsp's. But it becomes totally unavoidable when one is using master faders. And for some reason, Reference 4 (v.3 was not as cpu hungry as 4) needs far more cpu than any other plugin I tried.

    Having a DSP version would be fantastic, especially for tracking as the zero latency mode still is a problem to some musicians (and to me as well, sonically I definitely prefer phase linear result), but I have to confess that my little finger tells me this is an even lower priority than surround ability, considering the small number of users...

    Thanks again anyway, looking forward to reading about other's views on this topic. Keep up the good work,

    p@T

    Actually we'll deal with all HDX issues as soon as we acquire the hardware again. That includes a proper DSP for HDX, so hopefully this is one of the things coming in a near future update.

    Sonarworks as AAX-DSP would be a dream come true!!!
