I was digging around youtube learning about the Ondes Martenot last night, and loved the expressiveness of the “Touche” or “Lozenge” played with the left hand. It controls the volume envelope seperate from the note selection, like the bow of a violin or the breath of a trumpet. The artist quickly goes between soft swells and percussive bird chirps:
I was just wondering, does anyone know what sensor/mechanism Martenot used here? The springiness looks just right. I’m making my own MIDI controller and hoping to work in some monophonic expressiveness (I’d like to make an MPE controller in the future, but taking baby steps for now). I’m thinking I could add a Lozenge and transmit the expression as a MIDI aftertouch message with 7 or 14 bits of resolution.
