Modulus
Modulus used to be Paul Maddox (UK) little synth company doing a 25 unit run of the Monowave.
He did the very promising and now open source, Monowave II for the DSP based Chameleon platform. He also made a polyphonic version of the Monowave for this platform called Phoenix. Both of his DSP based projects included a unique filter slope parameter to mix the output after the first pole and the fourth pole. Thus giving a 2 pole (=12 dB/octave) bandpass. very much like the Oberheim filters. But with the character of the Moog ladder filter. But due to the break-down of the Chameleon hardware builder in Spain, he stopped work on this.
Now he quit all activities on synth building and playing. He started to play electric bass in a band.
He also made music under several names like:
Paul Anthony
MadHouse
also runs a huge web project http://www.synth.net
was very much into Wavetable Synths like PPG, Waldorf and therefore made the Monowave
