DDSP-FM is a fork of the official DDSP library. This version includes the following new features:

• a differentiable 4-op FM synthesizer
• a differentiable AM synthesizer
• a new operator, mult
• a new TFRecord, suitable for future develpments, such as preset matching
• a flag for stopping the training if losses are NaN

💡 Timbre matching demo

This notebook will create a random preset for the FM synth, generate 48 pitches and train a NN that will create a patch as similar as possible as the original one, using only the spectrograms of the original preset.
