No. SoundHelix currently only supports the standard western heptatonic major and melodic minor scale. Other scales (pentatonic - including Japanese -, hexatonic, octatonic, etc.) are not available. This is not a fundamental restriction of the SoundHelix framework; rather, the implemented SequenceEngines and the PatternHarmonyEngine make use of the standard scales. By design, SoundHelix also does not support fractions of halftones or scales that divide an octave into more or less than 12 frequencies.
