Hi!

I am using the modmatrix opcode to make a plugin to control other vsts.

For some reason, the table doesnt update properly when I load presets.  
Both using Reaper presets and the cabbage preset system dont update the table. One value it can handle, but somehow more just doesnt work?  
Any ideas?  
I’ve been trying different things all day yesterday with no luck.

Here is the full csd file:

Here is the snippet that likely is causing the problem:

Sorry, i’ve never used that opcode, and can’t follow the code you posted as I’m not really sure what you’re trying to do. Can you produce a simple, extremely minimal csd file that illustates the problem?

haha, my bad, should have been a bit more clear. Symptom of staring at this code for so long.

Here is a simple version of the ModMatrix instrument  
[ModMatrixCabbageSimple.csd](https://forum.cabbageaudio.com/uploads/short-url/ovjTwYIZhWkiQQZG5KqfIDXcQgr.csd) (22.3 KB)

So: when the I update the UI, it writes to the table as expected. When I load a preset, either in cabbage or in Reaper, the UI updates, but the table does not.

Hope that’s a bit clearer \<3 🙂

</div>

Can you prepare a minimal example, this is still far too complex. As you know, Cabbage doesn’t save tables, but the fact that the UI is updating correctly means something is failing to trigger the table to write. The cabbage get value opcodes have an option trigger on i-pass parameter:

```
kValue [, kTrig] **cabbageGetValue** SChannel[, iTriggerOnPerfPass]
SValue [, kTrig] **cabbageGetValue** SChannel[, iTriggerOnPerfPass]

```

Can you try enabling that and seeing if that makes a difference?

> kValue cabbageGetValue SCoeffs[kIndex], 1

Is that what you mean? When I write the code like that I get an error saying;

> error: Unable to find opcode entry for ‘cabbageGetValue’ with matching argument types:
> 
> Found: k cabbageGetValue Sc  
> Line: 373

I also just now tried

> kIndex, kTrig cabbageChanged SCoeffs, 0, 3

but then the table doesnt update when I update the UI.

Yes please, you can grab them from here:

> **[Pipelines](https://dev.azure.com/rorywalsh/cabbage/_build/results?buildId=2800&view=artifacts&pathAsName=false&type=publishedArtifacts)**

There are 3 dots on the right when you hover over the Installers button, you can grab the installers there. Hopefully this will make a difference 👍

I think maybe I understand the problem?

With the code like this, when I load a preset, kIndex goes from 0 to 70. When I use printk2 it never changes. So somehow the index doesn’t update properly and thus it doesn’t write every nslider into giModScale table.  
Could that make sense, based on how the opcode works?

I’ll try and actually get a full .csd file that’s clear later:)

You could be right, this all sounds frighteningly familiar! Would be great if you could produce an extremely simple example so I can debug it more easily. 👍

I have hacked a fix lol  
I added a button that will trigger a loop that cycles through the entire list of nsliders, and writes to the function table. I have to manually press that after loading a preset lol

It’s not ideal to have to manually trigger the button. You never confirmed to be me what version you’re using?

p.s. the reason I ask is becuase this works as expected here with the latest build, although I’m testing on macOS.

Is it possible to create a kTrig that responds to a preset update? So when I change to a new preset a kTrig value becomes 1.

So “kTrig PresetChanged”  
or something.

I havent found anything (might be I have read over it)

Did you look at teh Newpresets.csd example file? It does this:

`SPresetFile, kTrig cabbageGetValue “presetChannel”`

where presetChannel is the preset button channel. It will update each time a new preset is selected.
