The CX5M was built to the MSX standard, which included slots for inserting programmed cartridges.
These extended the machines capability, accepting a range of games, office applications and so on.

Yamaha produced a range of cartridges including a programmer for Yamahas DX range of FM keyboards and a real-time sequencer.
Two of these, the Voice Editor and Music Composer, allowed the user to programme a bank of 48 sounds for the CX5s own built in synthesiser and to sequence up to eight channels of music, controlling the built-in module or external instruments via MIDI, in step-time using a musical-stave input screen.
