Wind controller modules are specialized synth modules that are designed to work with wind controllers. They typically support legato wind-style playing and can respond to the unique controller inputs, which sense breath, biting on the mouthpiece, and pressing keys. Wind controller players may use a specialized wind controller module such as the Yamaha VL70-m module or its predecessors, the VL-1 or VL-7. As well, wind controller players may use general-purpose rack synths such as the Yamaha Motif XS Rack, Roland Fantom X, or the Roland Integra-7 rackmount MIDI sound module; however, these general use synths require extra wind sounds or "patches" to work well with wind controllers.
