The new modules from Ieaskul F. Mobenthey should be ready to order soon.
In addition there is a barre controller, which is a simple passive affair, no circuit board,
just four bars with piezo and output jack (the inputs of Mobenthey modules are tailored to take piezo)
Tocante has made a version of the rolz-5 circuits. It is an expansion board for the plumbutter. Plumbutter has that nice voltage control for each of its rhythm generators (rolz) but they lack the pure crunchy ultrasound paradox capability of the simple rolz. This expansion board is to make up for that; the rolz are tuned by capacitors, in the range of 1 microfarad, through 1.5, 2.2, 3.3, 4.7, 6.8, up to 10 microfarads (allegro to larghissimo). The odd beats and strange interjections are caused by wiring them to each other. They are all "brown nodes" as on the plumbutter, androgynous, both input and output. Here, they are processed by plumbutter's ultrasound filter, and a gongue and snare drum.
