The previous version was better

Compared to the predecessor MM 2008 Producer Edition (with patch 13.0.3.2), the new version MM 15 Premium (release 15.0.1.6) although a lot stylischere surface but without additional functional benefit and at the expense of CPU load (with the same Arrangement tested). Also MM showed me a few innocuous but annoying, reproducible Macken 15 Premium. The only real gain would be the Beatbox 2, after which the face of hundreds of freeware VST plug-ins in Internet confidently but can do without. One has to note that MM is an object-oriented real-time system, and users with a wide access paths to one and the same sound object allows simultaneously. Similar to a car: The driver can simultaneously accelerate and brake, but should not be surprised, if it means the engine "stalls". After I stopped at MM aimlessly clicking around, and instead advancing as planned and useful no more crashes have occurred.
MM 2008 PE has in me 5 stars for a fantastic price-performance ratio. MM 15 premium I have de-installed again, because I could not get used to the bugs even after a month.
