DHO Harmonic Osc Card Expander for Buchla Music Easel

4U Shop DHO

The DHO from 4U Shop is a digital harmonic oscillator and expander card for the Buchla Music Easel. It features five digital sine wave oscillators, four of which are harmonics above a fundamental oscillator, the frequency of which can be adjusted independently with the onboard slider and CV input. Additionally, each harmonic's volume can be modulated independently with their respective slider and CV input. This format offers a ton of creative potential, allowing you to add an evolving organ-like sound to your Music Easel. Each sine wave is 8bit, at 66.8 kHz, giving at a lovely lo-fi sound. The volume of the DHO has its own manual volume control, along with a Tini jack for the output. If you're looking for a new creative tool for your Buchla Music Easel, the DHO from 4U Shop is an open-ended harmonic toolbox.
