NAM A2 and Slimmable

@fer @gianfranco This is now implemented, so it can be set at compile time for the Dwarf.

I tried changing also the default in the .ttl, but the noise issue, sometimes at the pedalboard loading, still occurs… As a test, I did a patch in your CompositeModel.h just to use the smallest model for all qualities and now the noise does not occur any more :-)… I think it could be related how MOD software handles parameters with pedalboards, presets and snapshots, only one parameter is changed at a time, and perhaps somehow the plugin gets initialized with Full quality.

Thanks @MikeOliphant !! Although I have mixed feelings about setting this for MOD Dwarf. Considering most of NAM models are closer to 12dBu than 2dBu, and not all are calibrated, I think I prefer to keep a Gain Plugin just before with -10dB. This is also related to MOD changing one parameter at a time, when you change a preset of the NAM plugin you get for a very short time an inconsistency of the input level with the neural model..

What I don’t understand is where a quality value over 0.5 is coming from? The saved preset value, the lv2 port default, and the internal default value should all be less than 0.5…

I dont understand neither. I double checked the pedalboard complete folder and plugin presets and nowhere there is a quality greater than 0.5…

@fer FYI - the latest version of my lv2 repo has a significant performance enhancement for NAM A2 full. Not sure if it will enable A2 full for Dwarf, but it might be worth a shot…

To get the improvement, you need to cmake with:

-DENABLE_MULTIFRAME_8X8_CONVOLUTION=ON

and use a pretty recent compiler (ie: gcc15). I think @falkTX has a branch of mod-plugin-builder that enables gcc15 for Anagram - maybe the same can be done for Dwarf?

@MikeOliphant ohh good to know. Thanks!!

I will try as soon as I’m back from my holidays in a couple of weeks, and report back the result. Probably gcc15 for dwarf is not easy for me, but let’s do it!!

My first experiments with the new NAM A2:

This is awesome.

2 NAM’s for a greasy stereo blend, an IR cab, a Dragonly, an EQ and some pedals and while playing I’ll go to about 77%!
