Mpc Sequences, Tracks and Programs Explained

The MPC's architecture follows a clear hierarchy where the Project sits at the top level, containing up to 128 sequences (1:08). Each sequence holds up to 128 tracks (1:20), and each track is assigned to a program. Understanding this three-tier structure is fundamental to working effectively with any MPC.

The MPC offers five distinct program types selectable from the track field (2:30) - Drum programs (for loading individual samples onto pads), Key Group programs (chromatic/melodic instruments that play samples across a scale), Clip programs (for launching synchronized loops), MIDI programs (for triggering external hardware), and CV programs (for modular synthesis via control voltage). Each type serves a different musical purpose.

Programs are independent entities created with the plus symbol (1:50). Drum and Key Group programs share a numerical sequence (programs 1-10 etc.) but are filtered by type when scrolling. MIDI and Clip programs maintain separate numbering lists (3:45), which can initially confuse beginners.

Multiple tracks can use the same program, but this can cause issues if the program is set to monophonic mode - notes on different tracks using the same program will cut each other off (5:35). In polyphonic mode, they layer properly. Each track remembers its last selected program when switching between tracks.
