The oscillator is a sound source that is capable of creating audio tones that will be used in almost every sound experiment you create with your Bits.The oscillator features a "pitch" knob to adjust its output tone and a "tune" dial for adjusting the tuning with a keyboard. It also features a mode switch that selects between "square" and "saw" waveforms. The "square" waveform has a rich, powerful character, and the "saw" has a more mellow, rounded character. The "waveform" switch changes the output. The invisible sound wave will either look like a square or a saw. The square has a hollow sound, similar to a flute. The saw has a strong, buzzy sound, similar to brass instruments. It also features a "pitch" knob in the center and a "tune" pitch dial. The oscillator's frequency range is 0.3 Hz to 4000 Hz. If the oscillator is turned very low, you can also use it to control light or motion Bits. Try making an LED pulse on and off by connecting it to an oscillator and turning the oscilator way down.- Synth Keytar
