Is his point about it having "a very different general character" to Repro accurate?

Well it's not trying to be a Prophet-5 for starters (can get in the ballpark effortlessly though). But in general it can and does mimic vintage analog characters (plural) extremely well. It's like an imaginary analog synth with ridiculous modulation possibilities. Kind of like Andromeda on crack.

I will test against my Andromeda and report back on the quality of the crack.

The filter in Proxima sounds pretty different from Repro-1/5. The Prophet-5 and Prophet 600 use different Curtis chips. The Prophet-5 is relatively clean and can have explosively loud resonance that punches you in the face. The Prophet 600 saturates right away, generating a lot of good-sounding extra highs, and won't suddenly become 5x louder in different parts of the knob range. Higher resonance in Proxima doesn't eat away bass as much as it does in Repro. I know the original synths are both named "Prophet" and they both use chips from Curtis, but they don't really sound similar beyond that. (At least, not any more than any two random vintage analog poly synths will sound similar. They all have pretty similar features, so they will all sort of sound the same, in a sense.)
Also, importantly, Proxima has a switchable 2-pole lowpass mode. You won't get that in Repro.
edit: I forgot to include the last and most important sentence. The multi/poly's Pro filter is based on the Prophet-5 one

The Multi/Poly's Pro Filter might be based on the SSM2040 found in the P5 Rev1 and 2. But I do not hear metallic zipper noise when slowly modulating it at self-oscillation.tumface wrote: Mon Nov 24, 2025 8:56 pm The filter sounds pretty different from Repro-1/5.

Edit: I was wrong about the PWM. But it would be nice to hear the harmonics bubble as the filters slowly sweep

Yes, I'm dumb. I hit submit before adding the last and most important sentence, which was that, if you want to see the difference between two Prophet/Curtis filters, look at the difference between Proxima and Repro. Whereas the multi/poly Pro filter is actually very close to the one in Repro. Bold and high resonance, relatively clean. The other filter models will saturate more. The SEM filter mode in multi/poly saturates a lot and is 2-pole, for example. Same with the MS-20 mode.

Any audio examples of this? I'm not hearing the fatness and saturation that I associate with say, a Prophet-5 (or Repro). It would be great if Multi Poly could cover a bunch of vintage analog ground, but I don't hear it replacing say, Diva + Repro. And again, I'm not saying that I dislike it's sound. I think it has it's own thing going on that sounds good. I just don't hear vintage analog in it's DNA. But I would love to be wrong, hearing some audio examples that show otherwise.EvilDragon wrote: Mon Nov 24, 2025 10:00 am Well it's not trying to be a Prophet-5 for starters (can get in the ballpark effortlessly though).

I was pretty excited to see Multi Poly released, because on paper it sounds like it has everything to take the crown for vintage analog emulation versatility + wavetables and other nifty features. But it doesn't sound that way in it's audio output to me.

There's plenty of it, the voice variation system is ingenious, the DSP is top-notch.

While I like the sound of it, I cab't get the filters to do that sort of harmonic picking or bubbling when I slowly sweep them at self-oscillation. Not even quantizing the envelope helpsEvilDragon wrote: Tue Nov 25, 2025 11:45 amThere's plenty of it, the voice variation system is ingenious, the DSP is top-notch.

That's getting nerdier than I want to get with a synth anyway, even if it did get there.
I mostly just want to twist a handful of knobs and go.

You're right. It's distracting me from making music. But when I heard that metallic filter sweep from Softube's Model 84, I fell in love and wanted to see if other synths had that effect.sellyoursoul wrote: Tue Nov 25, 2025 9:47 pmThat's getting nerdier than I want to get with a synth anyway, even if it did get there.![]()

One of these examples is Omnisphere using the Prophet 5 wavetables. The other is Multipoly using the Prophet 5 osc, amp, and filter. I'd say the tone is spot on and I think it's better than any dedicated P5 emulation. Definitely passes as analog.

So Multi Poly's oscillator sounds like Omnisphere's Prophet 5 wavetable? That's cool, but it doesn't say much else.djanthonyw wrote: Tue Nov 25, 2025 11:14 pm One of these examples is Omnisphere using the Prophet 5 wavetables.

Omnisphere is on par with Acustica's Expanse5, so I'd say Multipoly is as well.sellyoursoul wrote: Wed Nov 26, 2025 10:25 pmSo Multi Poly's oscillator sounds like Omnisphere's Prophet 5 wavetable?
