I bought Mast Mix last year (mostly to support you guys being awesome and giving us Linux compatibility
) but when I finally needed to use it I found it's unusable. Almost every parameter change causes xruns and clicks/pops which quickly grow into the hundreds or thousands. Tried on two workstations (Mint 18.2 and Ubuntu 16.04) with both Mixbus and Qtractor and experienced the same results. It's a bummer because it really does sound great and it's so easy to use compared to building a chain of multiple plugins to achieve the same effect.
It would be a super-handy tool if it could work as well as the the DAW Essentials do! Looks like Master Mix has not seen an update in a few years so I'm wondering if you have any plans to update.
