Bastl Kastle Handheld Modular Synthesizer

The Bastl Instruments Kastle literally brings modular synthesis to the palm of its user’s hand. The module is battery powered for maximum portability and boasts a characteristically lo-fi digital sound. The synthesizer has three voltage-controllable parameters—Pitch, Timbre, and Waveshape—and utilizes three different synthesis methods: phase distortion, phase modulation, and track & hold modulation. There's also a stepped waveform generator that enables the creation of pseudo-sequences, meaning this synth literally has everything one would need to create a modular progression. 

It should also be noted that the Kastle is an open source DIY project, meaning users can manually adjust the firmware whenever they please via Arduino.
