I had to see this one with my own eyes. Its a MIDI powered 2-voice synth with MIDI control programmable parameters, including some kind of analog filter. All about the size of a car key.

The Ploytec Pi L Squared is an extremely simple device, the power that MIDI supplies is enough to power the custom programmed chip to deliver 2 voices together with a healthy selection of programmable parameters. The only way to access if via MIDI control data. As I said the whole caboodle is powered over MIDI. Simple - MIDI in, audio out on a single phono connector.

Our demonstrator did have trouble finding the sounds, but here's a demo of the system from the Ploytec site.

20 years ago perhaps, but what in the name of God would be a practical use for this now. Oh well, should never really knock people for inventing stuff I guess

Would definitely be useful in those situations where you only have a controller keyboard and dont fancy bringing your laptop/synth. They could build it a lot smaller using SMD components. That way it probably COULD fit in a key fob. ANd MIDI powered??? Awesome!

I can see how this would be useful, in terms of hooking up to a phone or ipad style device "on the go", with a headphone socket, perhaps. It#s still embryonic, and maybe theyll make something with 4 or 8 voices..who knows? In any case, this is a great, cheap, low cost, low power device, which is NOT GM based, and sounds very analog-ish, which is only a good think in my book.

If I were the company, I would promote it like this: "Turn a boring, outdated MIDI controller into an analog synth"

It's so small you could probably pop it into the case of a little MIDI keyboard. Split the MIDI out, one to the usual jack and one to this, then drill a hole for the RCA output jack. VOILA!

Or add 2 analog voices to a cheap MIDI analog synth like the Poly-800 or Juno 1.

Mod city.

One of these (or a meblip micro), an arduino and some cheap sensors = a super I expensive core for interactive ski d art. Things like this really open up the possibilities.

That was supposed to be "sound art" not "ski d art".

I think this looks super fun, and will bring a new sound for those people who want an "Atari" type sound in their arsenal. I like things like this that have a sound of their own with lot's of artifacts. We'll probably hear this on the next Crystal Castles album or some such thing.

Way to bring back the 90's! Maybe this isn't something you understand.

Also, from the manual re "analog filter": Note : this parameter isn‘t useful for dynamic control because disturb- ing noises can occur while playing notes and changing this parameter at the same time.

Maybe a good thing ... but I doubt it.
