I suspect that this is due to the recent upgrade to vst sdk 2.4.
I'm aware that this version of Cubase is "old" software, but I would like to support as many hosts as possible. Unfortunatly going back to vst sdk 2.3 it's not a viable option.
I will try to investigate if the sdk is in fact the problem, and find a workaround.
Meanwhile I'm very interested if anyone reading this know of other vst's that have this problem, or know any solutions/workarounds?
and some Windows 7 dll dependencies were removed in KarmaFX Synth v1.15.
This seems to have fixed the Cubase SX 3.x.x problem under Windows XP.
I'm awaiting the final verdict from the bug reporter(s).
While v1.15 is detected as both vst 2.3 synth and effect, it does not appear in the midi out menu, and therefore cannot be used as an instrument on a midi track! (see image below)
I'm not sure what the problem is yet. It's likely due to the vst 2.4 sdk upgrade, but I need to figure out a valid fix. Until then, v1.10 is the latest working version in Cubase SX 3.x.x.
I'm thinking that it might be possible to workaround the issue, i.e., by loading the synth inside a wrapper vsti (e.g. like Chainer, http://www.xlutop.com/html/chainer.html ), but I havn't verified that yet.
Please let me know if you figure out a temporary workaround!
Seems it was due to the vst 2.4 sdk and the deprecated wantevents() call.

I'll be in the shed, making a new build...
Users having midi issues in Cubase SX should download their installer again.
Verified in Cubase SX 3.1.1 by Klaus:
"super, it will work again with "Cubase SX 3.1.1"!
KarmaFX Synth can now again assign a MIDI track.
Thank you for your effort "
