About SynthMaster
___________________________________________________

SynthMaster Player v.2.9 is included. This award-winning synth by KV331 Audio has thousands of presets that are especially useful for modern, techno and arpeggiator sounds. SynthMaster support built into Band-in-a-Box includes:
- MIDI SuperTracks and styles that use SynthMaster sounds.
- Access to SynthMaster sounds using the Hi-Q patch dialog, so that choosing a sound can be done just by picking a patch. On the Tracks menu, choose 'Select Mi-Q MIDI Patch Plugin' and filter by 'SynthMaster'

SynthMaster is installed to these folders by default:
C:\Program Files\KV331 Audio
C:\Program Files\VSTPlugins\KV331 Audio

Note: SynthMaster VST is a 64-bit plugin only. There is no 32-bit version available.
