Claims

[Scope of Claim for Utility Model Registration] A manual performance input device, a tone setting input device, a sequencer memory for storing a sequence of sound generation instruction data and tone setting data, a sound source circuit having a plurality of sound generation channels, and a sequencer playback performance. Prepared for manual performance, each sound source channel of the above sound source circuit,
A channel-specific management memory for storing occupancy information for identifying whether manual performance data or sequencer memory data occupies a channel;
This information is stored as sequencer playback timbre information, and when the timbre setting data is read from the timbre setting input device, it is stored as manual performance timbre information, and when the sound generation instruction data is read from the sequencer memory, the sound generation channel , updates the occupancy information on the channel-specific management memory for the assigned pronunciation channel to the occupancy state of the sequencer memory data, and sounds the assigned pronunciation channel according to the sequencer playback tone information stored at that time. When the pronunciation instruction data is read from the manual performance input device, a pronunciation channel is assigned, and the occupancy information in the channel-by-channel management memory for the assigned pronunciation channel is updated to the occupancy state of the manual performance data, and then stored. 1. A sequencer electronic musical instrument, comprising: a control means for producing sound in an assigned sound channel according to manual performance tone information that has been assigned.
