Well, self-oscillation on 2 and 5 dies when cutoff is swept beyond 20-30KHz, which is unlike not some but every Pro One out there. So, I guess that none of RePro filter algos is working properly then, right?fmr wrote:
UNtil someone records the output of a Pro-One distorting in high resonance the way filter 1, 3 and 4 do, I am not convinced these are working properly in what concerns analogue modeling ...

I'm not sure what you mean. The self oscillation is loud, but it's not overly distorted despite its massive gain. There's a bit of K2 and K3 at like 50dB below fundamental. A Minimoog or an MS-20 have far stronger distortion in the self oscillation.fmr wrote:UNtil someone records the output of a Pro-One distorting in high resonance the way filter 1, 3 and 4 do, I am not convinced these are working properly in what concerns analogue modeling (and if the Pro-One also distorts like these, then... well, let's say I would never buy a synth that would do that). If they are not, for me they're out, no matter what character they have, or how lovely are the basses they produce.
As urosh says, the "thing" about the Pro-One are the heavy DC offsets which are only compensated by a, well, underspec'd RC-highpass *after* the filter (but before the resonance). Furthermore, the waveshapers are not your typical soft clippers - they're not smooth at all. This creates a challenge for any attempt to save CPU because they all explode or behave erratic. If you could run RePro at a sample rate of 1200kHz (equal to 32x oversampling), 1,2,4 and 5 might sound almost exactly like 3. But 3 already sounds like 3 at 96kHz (2x oversampling).
I'm still working on the paper, we have loads of other things on our plate currently.

I'm not sure if I'll have the time, but if I have, I will try to create some simple filter sweep patches with high resonance in DIVA with the Minimoog, the Júpiter and the MS-20 filters, and then some closer patch in Re-Pro, and bounce all the results. I didn't remember to do this before, but now that you called those to the table, I think it may be an interesting experimentUrs wrote:I'm not sure what you mean.

As a Pro-One owner and user, I have to say that number 1 is the furthest from the Pro-One filter sound, even though it sounds really nice. My votes go to 5 and 2. At first I was all for 5 until at a certain point I thought it behaved in a way I never heard from mine. And that's when 2 gained points.
So, definitely not 1.

And the good answer was in fact...If you could run RePro at a sample rate of 1200kHz (equal to 32x oversampling), 1,2,4 and 5 might sound almost exactly like 3. But 3 already sounds like 3 at 96kHz (2x oversampling).

Did you try comparisons with oscillator 2 audiorate modulating filter cutoff at self oscillation?ednolbed wrote:As a Pro-One owner and user
That's where the differences become most noticeable, and where 2 falls down.

I remember an old thread on Gearslutz where someone took the UAD Massive Passive plugin and the hardware and did a blind A/B. Prior to the results being revealed, the plugin held a slight lead. After the results were revealed, I believe the results began skewing towards the hardware. Wouldn't it be funny if 6 months from now, this thread were still alive and 3 were suddenly in first place?Ivan_C wrote:And the good answer was in fact...If you could run RePro at a sample rate of 1200kHz (equal to 32x oversampling), 1,2,4 and 5 might sound almost exactly like 3.

maybe... then we just need to wait with the release until that's the case. Then we can say "this is what the people wanted"Funkybot's Evil Twin wrote:I remember an old thread on Gearslutz where someone took the UAD Massive Passive plugin and the hardware and did a blind A/B.

OK, this now seems like talking about football (our football) in the cafe. Anyone chose his/her team by now, and are not listening anymore, just defending their option against the "oponents"
