The ED116 is simply an extension of the ED115 with the [VIOLET] colour controls ([RED] and [BLUE]) bought out as user controls.

Similarly the [RATE] control allows for adjustment of the 'speed' of the [RANDOM] output.

This updated version now includes an A440Hz sine wave reference signal that can be used for tuning purposes. This section can be turned off when not in use to reduce possible 'noise' issues.
