DIFFERENCES BETWEEN SPOTLIGHT SOLO STRINGS AND SPOTLIGHT STRINGS 4D added new "long" samples for 1st violins and cellos added new spiccato samples for 1st violins and cellos More enjoyable playability, out of the box. Intuitive expression so you don't have to "ride" vibrato and expression controllers. Human sensing - If you play notes short, then the instrument will respond crisply. If you play long, the instrument will respond in a more connected manner. More "intimate" sound if required. Easier interface. Overall sound is much more "open" and "shimmering". Legato feels much more fluid. New "Priority" parameters available. (For vibrato amount, vibrato speed, vibrato fade-in time, and Marcato level.) With this feature, you can select Velocity Priority, Slider Priority or CC Priority. So, for example, if you choose Velocity Priority, the feature will follow your playing style where velocity is concerned. However, if you should access the slider or CC while holding a note, it will softly take over. This feature makes playability much more flexible. In "Velocity Priority" mode, you can set a maximum for limiting vibrato amount and marcato level. Vibrato controls are much more intuitive - the best in the industry. For the Ripieno groups, there is a deeper, more lush vibrato available. New "Vibrato Now" feature that, when engaged, lets you have the soloists play an instant vibrato with no vibrato fade for added emphasis and reality. Ripieno (now called "ensemble") level and pan is now available. Dynamics are more deep A new "Run Mode" feature that automatically senses if you are playing fast runs or arpeggios, and engages specially-programmed groups. User-settings are automatically saved - no need to save the instrument to preserve your settings. Articulation changes can now be automated via standard UACC settings. Long - 0 Tremolo - 11 Spiccato - 42 Pizzicato - 56 Half Trills - 70 Whole Trills - 71 Tremolos and trills can be crossfaded with the "Normal Bow (Arco)" articulation. HPC adjustable for solos Portamento now works on all articulations, even pizzicato. More IR spaces. Microphone distance is now available.
