I own the Air Complete Bundle and 2 SoniVox products. Especially the Sampler "Structure" is completely unusable for anything but playing back the sample library, if you're lucky enough to get that going. It's still sold for over 120€ sales price afaik.
One of the FX Plugins has a broken gui, another just outputs noise on 0dB. All the products seem to have similar issues when it comes to file operations, that lead me into thinking they where compiled against an old Windows dll that has been subject to significant change over the years. If that was true it would mean fixing all of them would be a matter of recompiling on a modern system, maybe adjusting less than 5 lines of code. Nothing that would take even the worst coder in the world 2 years or more. That's how long some of these bugs existed.
P.S.: Funny enough, M-Audio has still a brilliant hardware support, the best I've ever encountered in my life. The guy literally sat down with me and discussed the circuit of my broken device, sent me parts of the relevant schematics (with blanks) and helped me to fix the electronics of a $200 keyboard, which's warranty had been over for a decade. That was just a few month ago.
I have all of the AIR instruments and most of the SONiVOX. I have no regrets with the AIR stuff, it all mostly works for me and there are some great sounds in there. The only exceptions I have seen with them is with Strike, when trying to export files, and with entering text in Structure. Sure the interfaces may be dated but the sounds are very usable. I didn't bother with their FX, as I picked up the Select bundle, rather than Complete.
But SONiVOX plugins seems to have a few more rough edges that need some attention.
I imagine that it is all in the hands of inMusic now to decide how to allocate their development resources. It would help the product line tremendously if they would just do a refresh, fix the bugs and Win 10 compatibility, and maybe update some program browsers.
I bought my first PC MIDI interface from MIDIMan, the company that started M-Audio. I am still rocking a 1st gen Axiom keyboard and an M-Audio FW-410 interface that all still works on Win 10. So no complaints there, but I have heard some grumbling about certain legacy hardware drivers not seeing updates as they are end of life.
I really don't want to say what I'm thinking about inMusic, because there is still a chance that they may surprise us all!
