I think the subject says it all!!!!!!!!!

I'm not sure that all the effects would benefit from oversampling (which is what heppened to EQ8, Saturator, Operator, etc.). There are a couple of effects that certainly would benefit, Autofilter perhaps, but effects like the reverb wouldn't get anything much out of oversampling and I'm not too sure that Beatrepeat or the delays would either.

The ones that they upgraded this time round are the ones that really benefit from it. I guess they may do a few others next time. But like I said - it's not applicable to everything, only effects and synths that realy need to calculate high harmonics.

Yep, the filter would definitely be of much more greater use with an HQ mode, sounds pretty thin to me right now.

What I would also like to see is an option to turn the HQ mode on per default for these plugins when I add them into the composition.

heh

right click a plugin set up as you like, and choose "set as default"
now read the manual section about the defaults folder because it does a lot more than that.

Interpolation for the delays would be cool. Real-time software is not supposed to click...

Who's chipping in for a big banner? We'll hang a big banner saying "Real-time software is not supposed to click" in the Ableton cafeteria.
At the very least it could spark an interesting dinner conversation.

yeah, but that's a different thing from a high quality mode.

Interpolation actually reduces high harmonics as it acts like a lowpass filter, averaging out the sound. Thats only if it is always interpolating of course, but still ... it's a different subject really.

but yeah, I like interpolating delays - great for doing swoopy pitch dub-style noises when you waggle the speed.

Yeah. I know its a different subject. But the thread header ends with "...all effects".
High quality mode on a delay would be interpolation. No need for oversampling on a delay.

I thought he was referring to the specific "high quality mode" that they added - which is oversampling. Rather than a more general improvement of effects to add missing functionality.

Of course they would!

Also, everything should have a low quality option for that sound..

Oh?
I'm not sure of the implications of oversampling in classic reverb models, I've only encountered oversampling where I've needed it - such as in distortion/waveshaping and filter models and I usually only implement it using dumb logic ... IE repeat the code block 4 times and then downsample.

that's not too hard in a filter - but reverbs I have left alone.
how does it help in reverbs?
I guess all those allpass filters operate better on the high end transients if they are running at 176khz (4x), or something?
frankly I just do what everyone else does - get hold of a copy of the freeverb algo and piss about with it.

I almost always have some saturation and LP filtering in a dub feedback loop; I find it helps to smooth the sound. Tiny speed adjustments are great too - get em right and you get something nice and shuffly like the Virus's modulating delay - sounds like what you're describing...

not quite, but yes - that's how I have my default delay return channel too.

An interpolating delay is the sort that you might find in a flanger, so that when the delay speed is increased and decreased there is a smooth transition between the speeds. Because in these cases the buffer is being accessed quicker or slower there is a speed increase or decrease, and in a flanger that is set against the dry signal to provide the traditional flanging sound. But flangers only operate on very short delay buffers.
If you apply the same bit of code to a longer delay you can modulate the delay time from 10 ms to 10 seconds in one twist of a dial.
Now, imagine that bufferlength of 10 ms suddenly stretched out to ten seconds - there is a concordant pitch drop ... a big swoop.
It's not an exotic effect really - Reasons default delay does it this way.
Digital delays are by default non-interpolating though, so someone somewhere made the choice to make the Reason delay a little more tweakable.

It's pretty damn easy to find a VST interpolating delay, you might even find one with a selection of interpolation shapes.

Hi Guys,
Operator has oversampling?

How mutch?

Because high armonics (on the audible range) in a "Saw D" has a considerably difference when rendering at 44.1Khz vs 96Khz.


Best,

oversampling came in Live 7 and must be activated in the Operator context menu.
I think it is 2x

if you see the Robert Henke video which is knocking around you will see a Robert talk about the modes and what impact they have.

big video, but worth a watch

prepare for monodeck lust though

Hi Angstrom thanks for your answer.

So when you activate Interpolation on Operator there is a 2x interpolation process involved?

Best,
