An electronic musical system comprised of an electronic musical apparatus and a musical control apparatus for remotely controlling the electronic musical apparatus, wherein:

• the musical control apparatus comprises:
• at least one operating element each adapted to vary a parameter;
• a receiver unit adapted to receive tone generator type information representing a tone generator type from the electronic musical apparatus;
• and
• a transmission unit adapted, in response to a user's manipulation on said operating element, to transmit to the electronic musical apparatus a parameter control command for controlling a tone generator parameter of a tone generator of the type represented by the tone generator type information received by said receiver unit, and
• the electronic musical apparatus comprises:
• a sequencer having a plurality of tracks;
• tone generators of different tone generator types;
• a designation unit adapted to designate any one of the plurality of tracks;
• a setting unit adapted to set tone generator types each selected from the different tone generator types to respective ones of the tracks;
• a transmission unit adapted, when any one of the tracks is designated by said designation unit, to transmit to the musical control apparatus tone generator type information representing the tone generator type set by said setting unit to the designated track;
• a receiver unit adapted to receive the parameter control command transmitted from the musical control apparatus;
• and
• a control unit adapted to control, in accordance with the parameter control command received by said receiver unit of the electronic musical apparatus, the tone generator parameter of the tone generator of the type set to the designated track.
