mute

mute --  Mutes/unmutes new instances of a given instrument.

Description

Mutes/unmutes new instances of a given instrument.

Syntax

mute insnum [, iswitch]

mute "insname" [, iswitch]

Initialization

insnum -- instrument number. Equivalent to p1 in a score i statement.

"insname" -- A string (in double-quotes) representing a named instrument.

iswitch (optional, default=0) -- represents a switch to mute/unmute an instrument. A value of 0 will mute new instances of an instrument, other values will unmute them. The default value is 0.

Performance

All new instances of instrument inst will me muted (iswitch = 0) or unmuted (iswitch not equal to 0). There is no difficulty with muting muted instruments or unmuting unmuted instruments. The mechanism is the same as used by the score q statement. For example, it is possible to mute in the score and unmute in some instrument.

Muting/Unmuting is indicated by a message (depending on message level).

Examples

Here is an example of the mute opcode. It uses the files mute.orc and mute.sco.
