4.2.2. Playback Settings
The two settings for Piano Instrument and Overtone Instrument control the instruments used for playing tones when you press keys on the piano, or labels on the Overtone Sliders. You have a choice between a large list of standard MIDI instruments, and between a sine wave generator that plays pure sine waves:
The first entry in the list, with the label Pure Sine Wave, uses a tone generator that plays pure sine waves with high accuracy.
All other entries use the standard MIDI instruments, and their sound depends on the quality of your sound card or of your connected keyboard. Their volume is controlled by the MIDI Volume slider.
The frequency of the MIDI Instruments may be less accurate than that of the sine wave generator.
This is the device for playing the sounds from the piano keyboard and the overtones (except for the “Pure Sine Wave” overtone sound, which is played through the wave output device).
