Abstract: This study discusses some of the shortcomings of Gaussian humanization and discusses how the articulation models developed by drummers can be emulated using a probabilistic model. An author's algorithm for “revitalizing” midi-parts of percussion instruments was developed. Various dependencies and regularities, which are manifested when playing drums, are programmed. The dependence of the notes parameters not only on the parameters of the previous notes, but also on the subsequent notes of the corresponding parts of the drum set was created. The dependence of the impact force on the position of the note in the measure is created. Thus, emphasizing notes in a strong lobe. Also, the dependence of the note's volume on the coincidence with the notes of other parts of the drum set was created. To increase the dynamism and liveliness of the party, the volume of the hat was increased before the impact on the small drum. A comparison was made of the amplitudes of the corresponding notes of the parts, as far as the party, animated using a certain method, is different from the one played by a professional drummer. When listening to tests, batches processed using a modified method objectively sound lively than using Gaussian and quantized batches.
