[Repro-1] Public Beta

[Urs]

Hi Urs & team,
is there any chance to add Random and Alternate (as implemented in Diva) as mod sources and Output volume as mod destination in mod matrix?

Instead of Output volume I'd recommend Gain in SoniCon. There was a reason we didn't want Output to be modulated...

Yep, I've been thinking about some randomness. I'll ask Dave Smith why randomness / sample & hold hasn't been part of the vintage Prophet sound, not even the Pro-One. Other American Minimoog competitors such as the Odyssey and the Cat have it, even the Minimoog itself in rudimentary form.

Diva is a waltz, Repro-1 is breakdancing at a rave

Is that a slot to select different filters on the tweak page? Are more planned?

Yes. We want to have 3-5 flavours in each section for initial release. The envelopes are already there, but Oscs and Filter need a bit of work.

There won't be major differences in sound though - they're all going to be emulations of the same filter type. We want to match different calibrations and part tolerances to cover a wide variety of subtle, but audible differences - such as the difference between two Pro-Ones sitting next to each other.

In other words: Repro-1 isn't going to be an emulation of just one specific Pro-One, it's an emulation of many. The one in the first slot is modeled after the Pro-One I bought off a very famous synth player. It's been used on quite a few great albums. I have yet to clear if he's okay with mentioning him, and I really, really hope Vince Clarke lets us capture his on day.

Urs, any chance of getting the effect chain order to move around on the UI? I got tripped up today because the chain of stomp boxes is static even though the text names can be dragged and dropped.

Also, it would be cool if we could select and duplicate effects? For instance, I might want a Lyrebird for chorus, and another for delay on the same patch, but might not need the ResEQ. Would be great if I could swap one out for one more of the other.

Maybe in future... I was happy to spend time coding things that make sound rather than extending the formal capabilities of our framework, such as a sideways Zebra-style rack.

Tonight I'm running Repro-1 through my Toppobrillo Triple Wave Folder so I can to do a bit of a comparison with the built in Jaws wave folder. The TWF has three stages rather than 2, 4 or 6 (which is more similar to Intelijel's uFold) but Jaws seems to be based on casecaded Saw>Sine waveshapers (?) with a DC bias control on the input, so I should be able to do some of the same tricks. I could just use two stages on the TWF but I'm not really trying to 100% replicate the sound, one way or the other. I hope to post some audio tomorrow.

It's actually modeled after the principle in the Jürgen Haible design, but not a direct copy. It's not even a circuit simulation. However, it's heavily influenced sound-wise by the wavefolders I have (Intellijel uFold, Make Noise DPO, Verbos Complex Oscillator), I wanted to understand their behaviour and come up with my own (digital) design.

Here is a cool thing to do , the new Synapse Legend lets you access the filter section only, if you have BlueCats Patchwork you can feed midi into both and use the Legends filter and amp ADSR, drive and fx with the Repro !!!! Of course possible to do in a DAW but this setup makes it easy.

I just posted a first example about combining the new FX plugin of The Legend with Repro-1 (see at the end of the page in the thread at the link below):

when I marked some patches favorites, those stars went away after I re-booted Repro-1

I just checked with Mac VST2 and VST3, doesn't happen here. Do the stars stay/come back if you close the GUI before closing the project or removing/replacing Repro?

Repro locked up with a noted droning away on one occasion.

Did you maybe double-click a note on the GUI keyboard?

Great character to this synth, thank you!

When resonance is increased, the general volume decreases. I suppose this is authentic to the original, though I find it discourages me to modulate it. I would be happy to see an option to maintain more consistent volume.

Also +1 to micro tuning.

There are tricks to preserve overall gain when resonance kicks in, but they have side effects.

For now I just want to keep Repro close to the original.

Yes please, keep it close to the original, however when I compare with the original I feel the rep1 resonance a bit to sharp or more thin.
Another thing I noticied when I modulate the filter whit OSC A OSB B and LFO the filter sound more bright and thin and there is little aliasing at back, (even with this differences still sound great). To be more precise about the filter, the feel I have with resonance is : the first half of the pot is very close to the original.
One think as ever frustated me with the pro-one is the lfo linked to the sequencer, in your design whith help of the sync to daw we can have eventualy the lfo working in Hz and the sequencer in sync with tempo values, great! It would be fantastic to run both in sync with the tempo at different values. I love the pro-one sequencer for improvising on the fly Im so happy you didn't forget to implement it, can you ad glide beetwen notes to it?
Best regards,
D

I would love to hear your Pro-One. Would you be up to recording some filter sweeps at high resonance some time later? - We won't have time to consider yours right now, but the "chip presets" on the tweak page are there exactly for the purpose of matching more Pro-Ones.

You can glide between notes on the sequencer page. You need to tie a note to the next, and Glide must be in Auto position while Retrigger should be off for TB-303 style sequences.

Also, yes, we're evaluating LFO sync divisions for a later update.

Great, thank you. I record some of my pro one sweeps when I can, sadly I dont have my sound card with me for few days.

Maybe this is because I was doing too much too fast, though Repro locked up with a noted droning away on one occasion. I had to force quit Cubase. Not sure if a panic button is needed.

Hi Aaron, doing things too fast could actually have been the cause. One of the remaining issues we are still working on are some situations where CPU spikes can occur (as real-time peaks in the Cubase ASIO load meter). E.g. if you turn the clock rate control a lot, this can happen. Sometimes those spikes can last several seconds, 'locking up' the synth during this time. But usually, if you wait a short while, the ASIO meter will go back to normal, so you should not need to force quit Cubase in most situations. This will of course be solved in the final version of Repro-1.

The wavefolder is quite mad. When Zebra gets this wavefolder it will just scream

hmmm... somewhat similar (or maybe not) to an issue I had last night while checking the Sequencer and changing the Clock (but slowly, trying to hit all available time divisions) from 1/4 to 1/16, at some point the Sequencer locked up, hanging a playing note (W7 64bit, Live 9.x 32bit) but the Synth GUI was still functional, so much so that I was able to save that preset.

Removed that instance, loaded it again, loaded that preset and since then, wasn't able to recreate the issue

Thanks to those that posted patches. I agree that red stars on red is the not easiest to read.

I have modified the star's pictures for another contrast .

I'm sorry if this has been asked already, but how long will the intro offer last for? Will it be on until the end of next week? I'm out of town and would like to check it out at my studio first (funnily enough, I am in Berlin at the moment, though ).
