Korg multi/poly native - reimagined Mono/Poly Synthesizer plugin

[Gam456]

Sync seems a little broken with the waveshapers. If I create 2 identical waveshaper oscillators and chose the sine shaper, with 0 gain and offset and 50% pulse width and turn on sync, there's this fuzzy/crackly noise when most notes are played. Some notes do not have this and it's louder with some than others (but these change per octave). This goes away if I set scale all and osc drift to 0. It's quite a bit less obvious in mono mode but it also goes away completely when you turn off voice variation. It's also important to turn off the filters as these can mask it. I feel like this is likely a bug.

it seem there is aliasing, a bit less with the OS extreme mode

Love this thing, sounds great. Korg have been on a roll lately for me, just a really nice set of synths available.

Do you plan to implement multithreading in future versions?
Many users are experiencing crackling and ASIO buffer overloads.

A degrade in 1.0.2 caused overloads; 1.0.3 fixes the problem. Please update to 1.0.3, and let me know if you still see any issues.

I understand that.

I'll ask again: let me know if you still see any issues after updating to 1.0.3. If so, then we'll work to address them.

As far as I can tell, it's working as expected.

Sync operates on the sine or triangle input to the waveshaper. I assume that you're using the default sine input. With the Sine shaper and gain/offset at 0, you're hearing that sine input waveform. With Sync on, detuning either of the oscillators, even slightly, causes a discontinuity in the waveform; you can see this in the waveform graphics if you move the Tune knob. Both Drift and Voice Variation will cause detuning, which will vary from note to note as you observed. Sine waves have no additional harmonics, so the small amounts of high frequencies caused by these discontinuities are easy to hear.

Also, as Gam456 noted above, we're hearing some aliasing in this case, particularly when the sync leader and follower are almost at unison but the leader is very slightly higher in pitch (which again will vary from note to note if Drift and Voice Variation are active). Setting Oversampling to Extreme helps with the aliasing. The Waveshaper doesn't have the same amount of intrinsic anti-aliasing as the other two oscillator types; the rollover help for the Oversampling parameter notes that the Extreme setting may be helpful for specific Waveshaper setups.

Hope this helps!

I wish there was a simple way to constrain the random pan to a percentage from center.

Modulate Pan with Random 3 or 4 (bipolar), and adjust Intensity to taste.

Oh what the heck, this thing sounds incredible. I wasn't expecting it to, not sure why.

Extreme oversampling helps - thanks - as does removing all pitch drift. Compared with analogue (and even korg's own 2600), it still sounds a little sharp to me but I guess this could be used to some advantage I can also use the wavetable oscillator for really smooth sine sync. In this regard, it would be amazing to add a phase parameter to the wavetable oscillator. I mean, I would like to be able to set the phase for all three types but I understand that this might not fit the rationale behind the classic oscillator at least. However, for wavetables (going all the way back to at least the microwave 2) it's an important part of their sound.

Really great plugin, though. I foresee many years of exploring its possibilities.

I would agree having an option between freerunning and key reset with adjustable starting phase for oscillators would be a very good addition.

+1

Sounds silly, but that's the only reason why I not bought it. Phase reset is essential to some of my sounds, and I simply don't need "just" another synth plugin that doesn't fit my standards.

[suthnear]

There doesn't seem to be a ping pong delay option. What am I missing?

Other nice-to-haves:
- increased range for FM: it's a bit polite. I vaguely remember the monopoly being quite raucous so there is precedent for this
- filter drive. The drive works well but an overdriven mixer going into a filter is the source of many great and classic analogue sounds as it allows the filter to give the overdriven sound a haircut. I would even be happy if there was an option to choose between pre filter or post amp like it is now
- an sh101 style sub-oscillator for classic (not the juno 6 version - the phase relationship between the two is wrong IMO). It makes for a very beefy saw when the balance is just right. Being able to set phase when used with sync would make this largely unnecessary, though
- sine-saw and sine-pulse options for classic (buchla 258; synthi)
- 4 oscillators naturally suggest vector mixing
- ability for oscillators to drop to LFO range and/or increased rate of LFOs. 32Hz is not quite there. I appreciate that the latter might be difficult from the pov of existing presets, though

But it's really great as it is...

Yeah, that’s the work-around that I came up with, but it would be nice if “random” was a knob instead, that let you adjust the amount.

- 4 oscillators naturally suggest vector mixing

Can't you use the Kaoss Pad for that? Or just Assign the mixer to CCs and then a controller?

Well of course 4 layer patches such as Constellations produce crackling. That's unrelated to resolved bug.
What I'm saying, with proper multithreading you would greatly expand number of hobbyist users and there's a lot of them
Not many hobbyists would buy new CPU/computer because of a synth.
Personally, I've got 24 threads so I expect software to use these vast resources in efficient manner.
See what Arturia did with Pigments, that would help with multi-layer patches

Hi danatkorg

Request
For the pan, it would be great to have a mod source per voice like an alternate

workflow
I notcied something weird with the sequencer

The pulse reproduce the same lane as SEQA. Why ?
Also if I change the transition on the bottom to log, it doesn't change on the lane.
The transition show linear.

Have a look
