"Drift" parameter on waves engine

[rgarner]

If you:

- Turn Parameter Display to "All"
- Use the USR/WAVES engine on the third oscillator
- Hold SHIFT while turning the MULTI SHAPE knob

... you see a 0-100% "DRIFT" parameter change.

I can't discern any change in sound.

Anyone else had any success making this one do anything?

Good catch, I wonder if that is new...Since the 1.12 update? I don't remember seeing that before but I guess I could have missed it. I don't hear any change at all when tweaking it. Man, feels like we are out in the wild west here fending for ourselves.

Have you noticed all the blank slots in the manual under the Program Edit Mode, Function Mode and Global Modes? Looks like there is lots of room to add functionality in the future.

Its supposed to make a drift in the pitch between Wave A and Wave B in the user oscillator, but its very subtile, I can hear a little difference when the shape is bright.

You can read more about it here, under User Oscillator:

Yes, I tried it again tonight. It's there, but it's *so* slight. Useful though. I do like the Shift/knob combos – reversing the LFO sawtooth with it has been very useful – but in the case of the second multi-engine operator it feels like it should have been front and centre.

I'm not too worried so long as every target gets a MIDI CC. Not much is there so far. I've written an extra sine LFO in Logic Scripter and mapped all the params that can be routed to two targets if anyone needs an extra LFO. I'll bump that count to 3 extra LFOs with a few waveforms when I get the time. Finding it most useful for modulating the existing LFO's rate, as that's the thing I miss most from the Minilogue...

EDIT: thanks for the masterclass link, Synthee. There are still a few things I've not found in there. I skipped right past Triphase and a love a good Solina patch

Looked into the code for what it does:

Code: Select all

inline void updatePitch(float w0) {
    w0 += state.imperfection;
    const float drift = params.shiftshape;
    state.w00 = w0;
    // Alt osc with slight drift (0.25Hz@48KHz)
    state.w01 = w0 + drift * 5.20833333333333e-006f;
    // Sub one octave and a phase drift (0.15Hz@48KHz)
    state.w0sub = 0.5f * w0 + drift * 3.125e-006f;
  }

It just slightly drifts/offsets the second oscillator pitch. To give it that analogue feel.

Thanks for posting the link to the master class. A good and in depth article that explains many usefull things.

But when I tried to go in and do as they explained I noticed that the last update seem to remove the one user oscillator that used to be there. On my Prologue there are no oscillators in the user oscillators anymore. And consequently not possible to edit anyting in it asshown in the guide.
So I'm not able to follow the tutorial and experiment with the waves that are supposed to be there.

Could it be because I have tested the library software? I haven't used it to write anything to my Prologue as far as I know. I just wanted to see what it looked like and to verify I'm able to use it.
It does show that all user oscillators are empty.

Hi akb. I had a similar problem post-1.20. First, have you performed all the steps in the update PDF? There are three – the firmware update itself, a panel update and a voice update. That last one is critical – I forgot it and one of the symptoms was that WAVES ceased to work and then disappeared entirely.

Second, once all three parts of the update are applied, and if your WAVES oscillator is still absent, you need to restore it by *either* performing a factory reset (back up your patches with Librarian first) or dragging the

Code: Select all

waves.prlgunit

into the User Oscillators section through librarian. I dragged mine from my clone of the SDK, but then had to perform a factory reset for an unrelated reason.

Hope this helps.

Thanks for the help.
I did the opdate according to the PDF, but in my case I only had to do 2 of the operations. The firmware update obviously, and the voice update. But I did the check to see what updates I needed as the PDF explains, and it only showed that the voices needed an update, so I did.
But I just got the synth, and it might already have the panel updated. I get the same versions as others here report to have when checking.
I know the oscillator was there before this update, but upgrading did remove ot for me.

I did find out that the librarian software come with a file for the waves oscillator, and was able to install it. So I'm ok now.

Looks like they changed this "Drift" parameter in the latest update. It now says "Shift-Shape 0%-100%" It does something but I can't tell what. Love the guessing games Korg likes to play.
