FluidSynth Object

This is a convenience class to abstract out the configuration of the Calf Fluidsynth plugin.

The class is a subclass of Lv2.Plugin and can be used in the same places.


class FluidSynth extends Lv2.Plugin {

Define the location of the soundfont file, change this path if the location is different on your system:


  SF_LOCATION = "/usr/share/sounds/sf2/FluidR3_GM.sf2"

The class constructor takes the patch number as an argument:


  constructor(patch) {

Create an Lv2.State object and set two key/value pairs:

the soundfont location
the preset patch number as a string


    local fluidState = Lv2.State({
        ["urn:calf:soundfont"] = SF_LOCATION,
        ["urn:calf:preset_key_set"] = patch.tostring()
    })

Call the base Lv2.Plugin constructor with the URL for Calf Fluidsynth and the initial state.


    base.constructor("http://calf.sourceforge.net/plugins/Fluidsynth", fluidState)
  }
}

Complete Script

class FluidSynth extends Lv2.Plugin {

  SF_LOCATION = "/usr/share/sounds/sf2/FluidR3_GM.sf2"

  constructor(patch) {

    local fluidState = Lv2.State({
        ["urn:calf:soundfont"] = SF_LOCATION,
        ["urn:calf:preset_key_set"] = patch.tostring()
    })

    base.constructor("http://calf.sourceforge.net/plugins/Fluidsynth", fluidState)
  }
}
