The MIDInight Express II is a real time, emulated wavetable MIDI jukebox and renderer. It runs with any Windows-compatible 16 bit sound card supporting a playback rate of 22050 Hz. No hardware wavetable support is required - even the simple sound circuits found on most laptops will do. The sound engine supports the extended PRG (patch) format used by the Mellosoftron III and WAVmaker III, allowing you to take full advantage of the Mellosoftron's patch editing capabilities for the creation of your own unique MIDI instruments. As always, the MIDInight Express is FREE!
