Although these commands are designed to be used within an RTcmix scorefile, they can also be used as part of an 'imbedded' application, working in conjunction with the RTcmix object.

The following commands are currently included in the RTcmix distribution (categorized below, alphabetical listing in the frame on the left):

General

• Minc -- overview of the default Minc scorefile parsing language

• len -- return the length of the argument
• load -- load an instrument into RTcmix for use
• rtinput -- open a soundfile or input device for reading
• rtoutput -- open a soundfile for writing
• set_option -- turn on and off various RTcmix options
• bus_config -- configure and connect the inputs and outputs of RTcmix instruments
• reset -- set the control function/envelope update rate
• control_rate -- set the control function/envelope update rate
• include -- imbed one scorefile within another
• index -- return the index of an item in a list
• exit -- terminate RTcmix
• f_arg -- return a floating-point argument to the CMIX command

• n_arg -- return the number of arguments to the CMIX command
• s_arg -- return a string argument to the CMIX command
• print -- print values
• printf -- print formatted values
• print_off -- stop printing of RTcmix stats to the screen
• print_on -- allow printing of RTcmix stats to the screen
• stringify -- return a pointer to a string argument
• system -- execute Terminal or Shell commands from within RTcmix
• type -- return the Minc data-type of its argument
