After connencting the Raspberry Pi and remote computer to the same local WiFi network, enter the RaspberryPi's IP address (keep the default ports) to enable control over WiFi. This is the normal plugin (v1.2.0), available for Windows (Standalone, VST3) and Mac (Standalone, AU, VST3). There are four main components to the guitar pedal:

Use NeuralPi only where line level inputs are expected. Guitar amplifiers expect a low level electric guitar signal (instrument level). WARNING: The audio output of the HiFiBerry DAC + ADC is at line level. Create your own models or use custom tones from GuitarML. Models trained from recordings of real amps and pedals can be loaded into the plugin for endless possiblities on your guitar. NeuralPi can sound like an amplifier or distortion/overdrive pedal using the power of neural networks.

The pedal runs high quality amp/pedal models on an economical DIY setup, costing around $120 for hardware to build yourself.Ĭheck out the step by step build guide published on Towards Data Science The NeuralPi includes model selection, EQ, and gain/volume controls from a remote instance of the plugin over WiFi.

The NeuralPi software is a VST3 plugin built with JUCE, which can be run as a normal audio plugin or cross-compiled to run on the Raspberry Pi 4 with Elk Audio OS. NeuralPi is a guitar pedal using neural networks to emulate real amps and pedals on a Raspberry Pi 4.
