lookup tables

@ustk said in lookup tables:

@ulrik the question is: what's the size of your arrays?

if not too big (max 128?) you should be able to use slider packs

It's 2 arrays with 15 values in each and 2 other arrays with 5 values in each, so not so big
So I'll test with slider packs then

Above this, you might consider a third party node to which you send the data arrays with a cable, perform that simple operation in C++ (in the cable callback so you leave the process untouched)

So it's not possible to do the operations in script node?

Then you output the result to a third cable that you grab in the network. for the last part, I haven't done such a thing but it should be possible

@ustk said in lookup tables:

@ulrik A small precisions needed:

• Do you need all resulting values at once or a unique value for a specific index?
• And are the array values pre-defined or dynamic?

That would change a bit how you want to handle it...

I need all calculated values at once

Here's your biggest problem. In script node you'll be able to get them one by one depending on the index value of a slider pack, not re-write an entire slider pack as output of the two. (Unless I'm not aware or smart enough to find a workaround)

Is the weighting knob changing at a modulation rate or just from a user UI knob? If it's the second then you might consider doing the computation in the UI script and just set one slider pack data connected to your network. Otherwise -> third party node, maybe...

@ulrik and what about this?
you can use two pack8_writer

[ulrik]

@ustk Yes that's a nice way, however I would like to have everything inside script node, because I will make a hardcoded fx and use it in a FX slot, and it would make a lot of scripting to connect it to slider packs as well as all other knobs in the UI when inserted.
But if that is the best way I will go that path...

I will think some more on this and decide later.
Thank you for feedback, it's much appreciated!

@ulrik The solution I've posted above is entirely inside scriptnode. However a pack_writer is limited to 8 sliders... Can you go with two of them?

Oh, I didn't realize, do you have it as a snippet?

@ustk I will explain what I'm trying to do.
I have 3 bp filters, 5 templates, (all with different freq and q settings for the 3 filters),
There is 3 select knobs that can select any of the 5 templates like, knob1 - template 1, knob2 - template 4 etc..
I have a knob that sweeps through, and interpolate between the 3 selectors chosen templates and interpolate all values between them so meaning:
Sweeper value 0: template bottom, sweeping up to value 0.5 (here's center) so
Bottom freq1 => Center freq1, Bottom freq2 => Center freq2 etc.., same with the 3 bandwidth values

When reaching the center and above, Bottom frequencies => Top freq etc
I have spent yesterday and a couple of hours today to figure out how to do this in script node.
If I could write some scripts (not in script node), then I could get it working, but in script node...uh..

@ulrik @ustk
I solved it using parameters, one parameter per index.
It's working as I expected

consolidated

expanded

@ulrik that one is quite a network!
There might have been a way to place all those in a C++ node with hardcoded arrays

Yes that's possible, but I have no idea how to do that.
Next time I'll learn
