Another one spotted on KVR

MOTU seem to be getting more third party developers on board, which is what is needed to challenge Kontakt's market share.

Now that DP 8 has gone cross-platform you'll see a lot of 
Third Party developers jumping in....there's going to be a 
HUGE market there...

listened to the demos - it sounds wonderful - then I looked at the price!!!! Bit too rich for me at the moment

Just to say I invested in Mach 5 some time ago (after some altercation or another with Native Instruments - can't remember which particular one!) and think its a great product. Motu as a company are helpful but UVi really are a great company to deal with I find - so I have over the past couple of years built a great library  - the most recent one I purchased was the Vintage legends - 6 vintage synths which all sound fabulous
