# Mars (Planet Series)

Mars is an amp sim / delay pedal. It includes 3 neural models, 3 Impulse Responses (Cab Sim), and a delay effect with dotted 8th and triplett modes.

Neural Network inference for the amp/pedal models uses [RTNeural](https://github.com/jatinchowdhury18/RTNeural)
The Impluse Response code is a modified version of the IR processing in the [NAM plugin](https://github.com/sdatkinson/NeuralAmpModelerPlugin) (MIT License) 

Note: Due to the processing power required for the neural models and IRs, Mars is a mono effect, which on the Funbox pedal is copied left to right channel for output. 
If a stereo signal is going into the input, Mars will only take the left channel for processing.
