1. Connect a classic pedal to a sound card. The left channel captures the original sound, and the right channel captures the effect pedal's output. Generate audio using host recording software.
2. Use the official ANN software to model, learn, and replicate this audio, creating an AMX format file.

The M-VAVE community's cloud training function allows you to record a file with a sound card, and the training is completed on the cloud server, providing AMXDATA files for import into the MK-20. Computer training supports NAM and AMXDATA formats.
