XtractorSynth Feb 2014 CTP

XtractorSynth combines a MIDI SoundFont engine, with a MIDI loop device. It is intended to be a low latency replacement for the Microsoft GS Wavetable Synth that is included in Windows.

This allows Xtractor to be used with controller keyboards and other MIDI devices without a built in hardware synth, such as some drum machines and guitar controllers without the latency that has previously been a big problem for these devices and Xtractor.
