Tryophyte is a monophonic touch-based synthesizer with an onboard touch-controllable bandpass filter. Each of the touch pads acts as one of three binary inputs to a frequency divider acting on the main oscillator. This allows for a playable scale consisting of an interval for each combination of the three pad inputs. 

​

The bandpass filter acts to shape the pulse wave oscillator and both resonance and frequency can be controlled via touch.
