Hi All,
Think a lot of guitar playes would like it to be available in Zynthian 
I use it already for some time now:
" NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows.
It supports *.nam files and, or *.json or .aidax files by using the NeuralAudio engine.
For Impulse Response File Convolution it use FFTConvolver
Resampling is done by Libzita-resampler
NeuralRack emulate a simple guitar effect chain with a pedal, a EQ a Amplifier and a Stereo Cabinet. The EQ could be moved by drag and drop to act as a pre or post EQ.
Optional, NeuralRack could run one Model, or the complete process in buffered mode to reduce the dsp load. The resulting latency will be reported to the host so that it could be compensated. For information the resulting latency will be shown on the GUI.
NeuralRack supports resampling when needed to match the expected sample rate of the loaded models. Both models and the IR Files may have different expectations regarding the sample rate.
The IR loader module supports two different modes, default is “Stereo”, that means it could load one IR file per channel, each channel have a gain controller. The second mode is “Mix”, that could load as well two IR files, but the output will be mixed together into a two channel mono stream. It have a “Mix” controller and a “Master” gain control. When only one IR file is loaded the “Mix” controller will do nothing and the IR file will be applied to both channels."
Cheers,
Maarten
