I hope this captures the feel of the original.
I used Berlin Orchestra (free) along with Surge XT in support for dynamic cello parts, brass, and some percussion.
My first batch is scheduled to be in the first production release of OB-Xf.
I'm cooking some patches for the upcoming 1.4 release, including:
I'm pleased with a new Grand Piano B that has low-end growl and high-end poise, and you can use it for classical renditions, accompaniment, or incidental lines. It includes stretch tuning and sympathetic resonance.
I also have C and D variants in reserve, in the hopes that creators will simply browse them to choose a piano. These names are unrelated to any other package of piano plugins.
I'm experimenting with section strings, focusing on a section violin first. In a production setup, you'd feed the same sequence to many instances of Surge XT with the patch loaded, the only difference between those instances is a controller that sets the 'unique instance' of the instrument. The rest is randomized and improvised in Surge.
Here's what that sounds like:
Initial results are great, with a good return of investment in sections of 6 to 12. It has the characteristic lushness of a string section, while keeping the tight control of the earlier solo violin variant. You can use the controllers while playing, to control bow speed, bow force, play close to the bridge, call out open strings, express manual or automated vibrato, and bite into the strings when you need. It also plays inharmonic whispers if you play it quietly, to achieve that feeling of music emerging from breathing.
By default, it comes with tuning as perfect fifths so the open strings work intuitively, and you can switch that to ET2-12, or load up just intonation, or whatever suits your music.
For section controls, there's a slider to change the variation of players in the section, and if you roll your sleeves up, you can change the distribution of players on the sound stage.
Best of all, it's all open for you to edit in the synth, so you can tweak the tuning, air and body resonances, string properties, section controls, and more.
