I read Simon James post and kept thinking how easily I might have written that same thing. I purchased MMV long ago and find that it is ALMOST a phenomenal synth - but the bugs that prevent it from being phenomenal unfortunately prevent it from being usable.
In the past I've reported a number of bugs to these forums (see Technical forum posts from "brad" Oct 19, 2004 thru Oct 21, 2004). When v2.0 was released as a free upgrade it fixed a number of these and I applaud the free major version upgrade. However, this version introduced a number of other bugs some of which for me are severity 1 show-stoppers .
An unofficial v2.1 version was offered by special request to resolve some of these bugs but again this version fixed some things and broke others that previously worked (see my last post on the Technical Form thread "MMV 2.0 -- GREAT! :-) but very slow mouse response").
I then reported a number of bugs via email directly to Xavier (who was by the way polite, professional and responsive). One bug is in the dual-delay and one in the sample and hold. Providing repro steps for these took me hours to reduce and isolate. Xavier was able then to easily determine that they were bugs in the denormalization routines and could be fixed but he had other priorities. That was Oct/Nov of 2004.
I currently have 3 midi projects that will not play through to completion due to the demormalization bugs in the patches I am using (so far, I only have 3 projects which use the MMV - that is, from my perspective, a 100% failure rate). My machine far exceeds the minimum hardware requirements (XP Pro, P4 2.7Ghz, 1GB RAM) and is rock solid for all other applications I use. Besides, the bugs reproduce for Arturia technicians.
So I check the web site every month or so to see if there is a fix yet. At some point I will probably quit doing that also and will lament how close MMV came to being a phenomenal product.
