So discoDSP just dropped TED-8, and it is one of those releases that made me stop what I was doing and actually read the whole product page. It is a plugin version of the Oberheim TEO-5, but not the usual "inspired by" job. They put a real TEO-5 on the bench and measured it knob step by knob step, filter movement, envelope curves, LFO speeds, every effect, until the plugin and the hardware sounded the same side by side. That is the kind of obsessive work I respect.
The best part is they kept the imperfections. Each voice sits a few cents apart and a touch louder or softer than its neighbor, so chords breathe instead of sounding like a photocopy. Then it goes past the hardware where it counts: 8 voices instead of 5, and a Poly Unison mode that stacks up to 6 voices on each of 8 notes, so 48 voices at once if you want to get stupid with it. There is also a 16-slot modulation matrix the TEO-5 never had, and the filter is that SEM-style state-variable one that glides from low pass through notch to high pass on a single knob.
The trick that really got me: if you own a real TEO-5, plug it in over USB and TED-8 becomes its editor and librarian. Turn a knob on the synth and the plugin follows, move a control in the plugin and the synth answers, and you can back up all 256 programs to one file. For industrial stuff this is a monster. Two oscillators with sub and noise, X-Mod for metallic bell tones, a 64-step sequencer with chords, rests and ties, and twelve effect types matched against the hardware's own FX. Run a detuned saw stack through the BBD delay and the rotating speaker and you are halfway to a track already.
It runs on Mac, Windows, and Linux, which is rare enough to mention, in VST, VST3, AU, AAX, and standalone. One honest note: it needs a one-time internet activation, then it works offline. Intro price is $99, going up to $199 later, and there is a $49 crossgrade if you own one of their other synths.
