"Here's a close-up of Natacha Diels fingers as she plays the birl prototype, set to the bass register. Fingerings are done with snap-acting momentary buttons with custom wooden caps."
YouTube via philtipping Note there is a Windows version. This reminds me of the Oberheim Cyclone and Techno Toys ARP-8

The following is the description for the first video from December 2007. It's meant to give you an idea of what this program is. Be sure to check out the site for updates. "A program for improvising, jamming or just having fun. Full info & downloads at www.philizound.co.uk under Freebies.
The Sequetron is a program for converting an ordinary MIDI keyboard or input device into a live sequencer-like instrument for real-time multi-track recording, playback & looping. The *same keys* you use to play also control the system while you are playing it, so you never need to touch your PC keyboard or mouse :)
Sequences can be recorded, played back, looped and controlled independently, and synchronized to an external MIDI clock if required. There is no restriction on the number of 'steps', nor does the sequence have to be monophonic; any notes & chords can be used. The output can be any MIDI device such as a synthesizer, drum machine, light display etc.
Sequence attributes such as pitch, velocity, channel, mute etc., can be changed while they are playing, either individually or in any combination; automatically taking place at the end of their respective cycles to maintain a rhythmic feel.
This ability to record, play & alter different length sequences starting at different times on-the-fly gives the Sequetron its unusual syncopated feel, encouraging you to experiment with overlaying and controlling patterns; even the most basic 1, 2 or 3-note sequences can create something totally unexpected."
"A lovely sounding organ / strings / polysynth . String sound is comparable to the Roland RS 202 and you can build up more complex sounds because of the 3 sections. PItch of the organ/string section can be detuned against the pitch of the polysynth. It contains an excellent ensemble effect in addition to vibrato and tremelo effect. Its a little heavy so best suited for studio use! The analog section strings/polysynth sound , to me , is very beautiful ; grainy ., a very physical real sound ."
"An early Roland mono synth capable of creating fat ,warm bass sounds. Lovely filter and you have the ability to mix in differing waveforms over 5 octaves for a really full sound."
