make some music now has released One Track Orchestra, a free orchestral VSTi oriented towards beginners and songwriters who need an easy tool to sketch their orchestral productions.
This instrument puts a complete orchestra on a single track of the DAW. Users can add strings, brass, woodwinds and even percussion at the same time, using only one MIDI channel. The plug-in was created using samples from VSCO Community Edition, and assembled with Maize Sampler. 32 and 64-bit versions of the instrument are available.
