Turbo Play includes a large set of the free Versilian Community Sample Library, including: The instruments are downloadable once. When you press F7 to load the Orchestra VST, you will be able to load in channels 1-16 the instrument you want. Most instruments come in combination presets (for example the Flute has a sustain and a staccato mode, the Timpani has a single/roll preset etc).

The Orchestra VST supports effects per preset or per channel, so you can load an instrument and apply, say, a compressor or an eq to it.
