Guitar amp and pedal capture plugin using neural networks.
Capture your own amps/pedals/plugins with Proteus. Can capture a drive/tone knob, or snapshot of the sound at a specific setting. Use the Capture Utility to quickly train models in the cloud with Colab. Effective for Amps/PreAmps, Distortion/Overdrive/Boost pedals (non-time based, no Reverb/Delay/Flange/Phaser).You can also capture a “rig”, or combination of pedals/amp.

This is similar in concept to a Kemper, Quad Cortex, or ToneX, in a free and open source plugin, with the ability to capture and share the sound of guitar gear normally costing hundreds or thousands of dollars.

Visit the GuitarML ToneLibrary Website to download Proteus compatible models.

Download the Proteus Capture Utility, which includes the input audio file and Colab script to train models.

As of Version 1.2, Proteus also features a 3-Band EQ (Bass, Mid, Treble) and a built in default IR (for convenience, recommended to use a dedicated IR plugin).

Proteus uses a LSTM neural network to emulate guitar amplifiers/preamps and distortion/overdrive/boost pedals. You can capture the sound of an amplifier either by recording with a microphone, or direct out from a load box. When running “Direct Out” models, you will need to use an Impulse Response plugin to accurately model the amp speaker/cabinet.

You can create your own models using the Automated-GuitarAmpModelling repository directly (LSTM with hidden size 40), or by using the Capture Utility files (available for download at GuitarML.com) with Google Colab (recommended).

To share your best models, email the json files to smartguitarml@gmail.com and they may be included in the ToneLibrary.

Loading models:

Download available models from the Proteus ToneLibrary. Use the Load Model button to select a folder containing Proteus json models. Note that models for NeuralPi and SmartPedal use a different model architecture and will not be compatible.

Capturing an Amp/Pedal/Plugin
Download the Proteus_Capture_Utility.zip to obtain the ProteusCapture.wav and ProteusCapture.ipynb Colab script.
Play the Proteus Capture.wav from your DAW / Audio Device and input to your amp/pedal/plugin, and record the output. Recommended to use a Reamp for impedence matching, and a Load Box for direct amp captures.
Upload the “ProteusCapture.ipynb” from the Capture Utility to the Google Colab website. Upload your out.wav file and follow the instructions in the Colab script to create a Proteus compatible model. Snapshot model training will take 10 minutes or less, and Knob model training will take around 30 minutes. For Knob captures, you will need 5 separate out wav files, as detailed in the tutorial videos.

Note: Recommended to follow along with the video tutorials listed above.
