Cool!
"The DSP is named. Texas Instruments TMS 320 S2069 U. This means nothing to me, but perhaps to the EEs here?" - GordonC
Beyond TMS320, I'm drawing a total blank on that part number. I'm thinking yet another typo?
From TFA:
"The Teremini has two antennas, one the heterodyne described above, which controls pitch, and a second smaller one to control volume whose output runs directly into the DSP."
Misspelled the freaking name! I think they may be saying the pitch side is heterodyned and the volume side isn't (which is actually what I'm planning to do).
"In the new Theremini we run the volume control signal directly into the DSP, which allows us to quantize the pitch with a knob"
Uh, what? I think they mean "pitch control signal" here. Or something.
"The Theremini has a small ring antenna (left) to control column and a telescoping vertical antenna (right) for controlling the pitch of a single note or any parameter in the internal or an attached music synthesizer."
Volume is way misspelled, and I could be wrong but I don't believe the pitch antenna telescopes? Who the heck wrote this? Par for the course when it comes to anything Theremini I suppose.
"Moog Music's Theremini is assembled in the US by a single person who is responsible for its (hopefully) high quality rating."
Hmm. This I kind of believe.
Brains! You can see that the speaker has what looks like a dual ported enclosure, which is good.
There is a separate circuit board right under the pitch antenna, I wish I could get a better view of that.
Ah, here's an enhanced view:
Looks like some kind of pepper beef filling. Who knew?
