Syntax

fluidCCi iEngineNumber, iChannelNumber, iControllerNumber, iValue

Description

Plugin opcode in fluidOpcodes. This opcode is part of the plugin repository and has to be installed separately. The plugin repository can be found here: https://github.com/csound/plugins

Sends a MIDI controller data (MIDI controller number and value to use) message to a fluid engine by number on the user specified MIDI channel number.

Initialization

iEngineNumber -- engine number assigned from fluidEngine

iChannelNumber -- MIDI channel number to which the Fluidsynth program is assigned: from 0 to 255. MIDI channels numbered 16 or higher are virtual channels.

iControllerNumber -- MIDI controller number to use for this message

iValue -- value to set for controller (usually 0-127)

Performance

This opcode is useful for setting controller values at init time. For continous changes, use fluidCCk.

Examples

Here is an example of the fluidCCi opcodes. It uses the file fluidCCi.csd.
