The Chromaplane is an instrument that uses two electromagnetic pickup coils to interact with a cloud of electromagnetic fields laid out in an isomorphic pattern on its flat surface. Designed in 2021 and refined in collaboration with KOMA Elektronik, it operates entirely in the analog domain, providing a responsive and polyphonic playing experience without conventional knobs or keyboards.

The Hacked Double Trumpet is a fully acoustic, modular wind instrument built from two trumpets modified with 3D-printed parts and adaptors. The air distributor directs air to multiple overtone flutes or other wind instruments, allowing for a customizable setup of pipes and sound outputs. 

The ModμMIDI is a modular, polychromatic MIDI keyboard designed for ergonomic performance of microtonal music. Its modular design allows keys to be removed or rearranged, enabling customizable layouts. Unlike hexagonal microtonal keyboards, ModμMIDI retains a familiar keyboard format for musicians and uses a polychromatic color system where colors correspond to pitch.

The Petika is a digital microtonal harmonium that augments the traditional Indian double-reed acoustic harmonium. It allows precise tuning control for each key, eliminating the need for multiple harmoniums set to specific microtonal frequencies. Using digital signal processing techniques such as asymmetric triangle waves, phase modulation, and filters, Petika recreates the tone of acoustic reeds.

The Udderbot is a DIY slide vessel flute made from a modified glass bottle, a flexible bladder, and water. It functions as an acoustic cousin to the slide whistle, ocarina, and musical saw, producing a sound reminiscent of both the flute and theremin. With a simple construction from household materials, the instrument allows for precise pitch control, microtonality, and expressive vibrato.
