One Track Orchestra

One Track Orchestra is a free software synthesizer developed by make some music now!. Available format(s): VST for Windows.

This is a simple and free VSTi plugin created to help you sketch/prototype your orchestral arrangements and productions in an easy and fast way.

This instrument puts a complete orchestra on a single track of your DAW (so you don’t need to create additional tracks). You can add strings, brass, woodwinds and even percussion at the same time, using only one MIDI channel.

The sounds of the different instruments are mapped on different sections of the keyboard, and they are velocity dependent. The only controls on the GUI are the reverb and volume faders.

This is a free sketching tool, created for songwriting/demo recording, and oriented towards beginners and songwriters who need a simple and fast tool, so it does not include multiple articulations or round robin samples. It is not supposed to be an alternative to big, professional sampled instruments and libraries.

The instrument is provided as-is, with no warranties. 32-bit and 64-bit versions are available. It should work fine on most DAWs. It has beed developed and tested on a Windows 10 PC and it worked fine with Reaper, Tracktion, Studio One, Podium, MuLab and SAVIHost.

This virtual instrument was designed by Luis Valoyes using samples from the VSCO Community Edition. The plugin is powered by Maize Sampler.
