Nectarine

This engine, developed by Shiru, has three tone channels with a further channel of interrupting drums. Eight levels of skew (sound loop duty cycle) values are available on a per-note basis. Individual note detuning is also available which can be used to generate a variety of effects.

There are two slightly different versions of this engine availabel in Beepola. The standard Tritone engine provides different volume levels for each channel (channel 1 is the quietest channel 3 is approximately twice the volume of channel 1, and channel 2 is between them). There is also a "Tritone (equal volumes)" variant which provides the same level of volumes on all three channels.

At the start of a new pattern, unless otherwise specified, the skew value for each channel will effectively be 1 (no skew - providing a clean tone). If the skew value is changed for a particular channel, that skew value will remain in effect for the remainder of the pattern until it is changed. This saves time when editing patterns as, for a group of notes that are to use the same skew, you need only enter it once against the first note rather than against every note in the run of notes.
