Very nice 1:1 comparison with real hardware

Based on the video poster by @lentferj, the square wave in repro-1 lacks the depth of the original. Is u-he aware of this and planing to improve this part? There a few areas where the repro-1 sounds brighter too.

Certainly doesn't lack depth as every Pro-One is a bit different from each other.

well, in the case of the square wave the difference is very noticeable and not to the advantage of the repro-1, I doubt this is a difference that can be attributed to a variation between models.

Actually this comment lacks depth
Murderous duck!

This is the era we live in, conclusions asserted re: vintage hardware and modern synths based on effin' Youtube Videos.

He was probably listening on laptop speakers, too :hyper:

Anyway, moving along.

If you're talking about the direct comparison around 3:50, I believe what you're hearing is attributable to a difference in duty cycle. Repro-1, being a digital synth, is able to hit that 50% duty cycle precisely, whereas the analog original sounds to be slightly off from a 50% pulse until the guy tweaks it around 4:30, at which point the timbre sounds extremely similar to my ear. Repro-1 is lacking nothing in depth; the raw square is certainly a tad brighter than his Pro-1. Good thing the filter is nice...

Go to tweaks tab, switch Oscillator modules from "ideal" to "P1", set PW to, say, 52% (as it's practically impossible to set a perfect square on a hardware with cheap pots), there you go.

In any case though, we are aware that every Pro-One sounds slightly differently. There is however no way we're going to chase up after every demo on the internet and tweak our algorithms.

Yep, I think you're right. Indeed at 4:30 things get much closer. Thanks for posting a constructive comment.

Yes sure, and we perfectly understand that. I was struck by the difference at 3:50 but that is explained by the difference in calibration so it's all fine, thanks!

Okay, I watched the video. Great job on repro-1 by the way.

Square waves don't have even harmonics, yet the "square" wave from the hardware pro-1 had a bunch of them.

The reason(s) for this should be pretty obvious - either the individual driving the pro-1 in the video had the pulse width slightly off center, or after 40-something years the pro-1 has drifted out of calibration, and that "square" wave isn't perfectly square anymore. Or both.

It's not a bug or shortcoming in repro-1. Just turn the pulse width on repro-1 to somewhere between 48 and 49 (or 51 to 52 if you prefer) and you'll get some even harmonics and the deeper tone that goes with them.

Edit - Lots of people beat me to it :)

On both our Pro-Ones it's actually impossible to get a true square wave. The falling edge has a slight slope. This can also be observed with other synths using the same VCO chip. IIRC the ideal preset in Repro doesn't have it but the P1 one does.

I am enjoying the squelchyness of repro-1! :)

Any chance of seeing a few more 'perform' modulators in the future? The current ones are certainly functional but I always fill them up and find I want a few more to achieve the sounds in my head.

I remember how all resistors could be bought in 10%, 5% and 2% versions. So a, say, 100kOhm could be 90 or 110 for the 10% version. Not even talking about capacitors and transistors.
Those were the analog days, not the zero and one days....

I had a Roland System 100, basic module and expander. Whatever you criticise about Repro-1, know that in 'those' days, this synth would have been a real shock. Build on the past, but don't idealise it.

I was not going to buy any more synths as I found I had enough ( Zebra, Bazille and some others). But, well,... I am very impressed, really. Congrats!
