FilterTable from 17.08 beta

[Kraken]

Just discovered this by chance. It could make for a much more flexible modal filter; do for modal filters what a wavetable does for oscillators. Dash Glitch has a video on Kilohearts' TableFilter if anyone is interested in the possibilities.

Here is a few comments that could help MeldaProduction write the documentation.

1. When analysing a sample, "wavetable" gives what you would want in a modal filter while "sample" is more diffuse, like you would use for an EQ. Please confirm.
2. I'm not quite sure yet how to interpret window and waveform sizes. If you can elaborate...
3. CVS files write what seems like the log10 of the frequency and the decibels. Please confirm.

In any case, thank you for this amazing addition to MSoundFactory.

Thank you for your kind words!
When analyzing a sample, "Wavetable" mode treats the .wav file as sequence of waveforms (as would result, for example, from MSoundFactory Wavetable module Export). The spectral shapes of these waveforms are used to populate the filters. "Wavefrom size" controls the size of the individual waveforms in samples.
"Sample" mode treats the .wav file as regular raw audio, from which it extracts a sequence of spectral envelopes. "Window size" controls the size of the spectral analysis window.
The filter envelopes are indeed stored in log10 of frequency and dB.

Let me kindly jump in here.
First of all, thank you very much for the new feature, Melda!
I was just wondering if there might be any plans to add it to MXXX as well, I think it could be really fun to use it outside of MSoundFactory.

Thanks. Congrats on Czechia qualifying. We had it easy this time (Canada)...

Ignore, google is my friend

The newest beta, came out today, has filter table in mxxx.

Anyone got any good sources for filter table files?

Yeah! Thank you very much Melda!

I presume you can use any that come with your wavetable synths but here are a few to start

I get a lot of latency and dropouts so far, but it's a beta so... Looking forward to next release!

I noticed that in Filter Table in MXXX, when the filter curve visualizer is open, the wave list automatically closes. It is impossible to have both open at the same time. This does not happen in MSF version.

And speaking of MSF, currently Filter Table is ony shown in Generator section, but not in FX, so it can only be used per-voice. Would be cool to have it in both sections!

This is due to the fact that it is a linear phase filter, so there is no way to get rid of the latency currently. Setting quality to low has the lowest latency.

Hey, thanks. We will take a look at this

Just some info about FilterTable:
The version inside MSF Generator modular has no latency.
If you load it in MXXX, there will be latency. Therefore, it is not available in the FX modular of MSF (latency in an instrument is not good). But, you can hack it if you really want, by placing MXXX in the FX modular and then the FilterTable inside that.

Interesting! Thank you for pointing that out!
May I ask why the same (apparently) plugin is linear phase in some cases but not in others?
Filter tables tend to be used in a drastic way (hard and fast modulation haha), so I wonder why the MXXX version is linear phase, as that somewhat "defeats" the purpose of fast modulation. Of course it is fantastic having a linear phase filter for static effects, don't get me wrong. Just wondering if a 'minimal phase' button could make sense like it does in MFreeFormEQ
Thank you jmg8!
