So I posted this demo when I first got my hands on CSB, for which I was most impressed by that particular libraries lower, chorale-fitting dynamics. Picked up MSB immediately for the auto-divisi and extra brass that neither CSB nor HWB had provided. MSB is certainly a different beast, but the reputation that LASS set forward and that even Genesis still carried is that these libraries need to be tweaked to fit what you're using them for. I replaced the CSB instruments with their MSB counterparts in the second demo below.
CSB only has C trumpets available, whereas MSB offers both C and Bb (1st - C, 2nd - Bb, 3rd - Bb, 4th - C). With the CSB demo, I transposed the second solo trumpet down and bumped the MIDI up by a whole step to emulate a Bb trumpet, which was necessary to get a strong timbral difference between the two. For MSB, I used the first and third trumpets, so both were Bb. This was for the richer tone in the lower range. I preferred the strong legato transitions of CSB, so I increased the volume of transitions in MSB by about 1db each, and lowered the legato speed of each instrument to the lowest setting. I used the Scoring/Film Stage depth control preset on each and made a virtual semi-circle to create a seating arrangement. I also used the mix mics on each at their default, and then brought in some extra close mic to add bite. Sizzle is also set to it's highest setting (this is a very subtle effect). Vibrato is controllable in this library, something CSB does not offer control of. This is set by default to CC2, which actually makes it very easy to copy parts between CSS and MSB. Finally, I set attack control to Velocity (trying to get closer to a CSB workflow since I was copying MIDI data), and raised the velocity response on the Horn a bit to have it respond quicker to the MIDI data. All CC1 data was bumped up from where it was set for CSB, as this library is generally softer than CSB.
Other than the stage presets, all other internal processing was turned off. Similar to the CSB example, the only external processing was a little Spaces II War Memorial and then the Ozone Maximizer to match the volume of the examples.
Edit: I know user demos are in high demand, so - while I work full time - let me know if there are features you'd like to learn more about and I can post accompanying examples when I have a moment.
