Hi,
Soundtoys has posted some news about AAX development on their facebook page:
http://www.facebook.com/SoundToys
SoundToys64bit in progress, and making headway. We have kept an eye on aspects of 64bit that cross over to AAX so when we're done with 64bit, we will be able to leap into AAX. AAX(DSP) is not in development. That will be on hold until we are done with 64bit. Once we begin AAX native, we will make the decision of doing or not doing AAX DSP, but right now, it's not in progress. That doesn't mean we won't do it, it just means we have to finish other things before making that decision.
I suggest that those who want to see Soundtoys AAX DSP in the future let them know that it's important. I would like to have Soundtoys DSP plugins available when i'll buy my new HDX rig for sure!
Thanks...
Luc
