What is a Wind Controller?Played like an acoustic wind
instrument.◦Breath◦Keys
Sends midi data to modules.Modules generate sounds
according to midi instructions.

MIDI Continuous Control #2 Breath
Velocity controls initial volume and timbre.
Breath controls:◦Initial and sustained volume
(dynamics).◦Onset (attack)◦Cutoff (Articulation).

Sound ModulesWind Controller
◦Sends midi messages to theSound Module
◦(Hardware or software) which Interprets data as instructions to
manipulate a Sample or sound algorithm (additive synthesis).
Sound is then output to a
Speaker or Amplifier

Parts of a SampleFour Basic Parts:
◦Attack◦Resonance◦Decay ◦Cutoff
![Page 17: A Breath in an Electronic World: Experiments in Musical Expression using a Midi Wind Controller Matthew Ahrens Mentor: Dr. James Bohn Bridgewater State.](https://reader030.fdocuments.us/reader030/viewer/2022032604/56649e5e5503460f94b583f4/html5/thumbnails/17.jpg)
Triggering Parts of a SampleCC#2 Breath used to trigger
parts on and off.◦Breath on sends initial volume and
timbre for onset.◦Sustained breath value maps to
loops resonance part.◦Breath off signals decay.◦Finalized with cutoff.

Hardware for this ExplorationRoland Fantom-XR
◦Four different samples uniquely controlled simultaneously
◦Large variety of effects and timbre controls that can be mapped to wind controller parameters
◦High quality of sample manipulation and output.

Issues with Wind Synthesis TodayUsed as an emulation device
◦Approximately 90% of commercial patches available are emulations (Patchman Music).
◦The rest are synthetic timbres modeled after steandard electronic voices E.g. Popcorn.
![Page 22: A Breath in an Electronic World: Experiments in Musical Expression using a Midi Wind Controller Matthew Ahrens Mentor: Dr. James Bohn Bridgewater State.](https://reader030.fdocuments.us/reader030/viewer/2022032604/56649e5e5503460f94b583f4/html5/thumbnails/22.jpg)
Issues with Wind Synthesis TodayAcoustic wind instruments:
◦Multiple timbre across registers.◦Expression achieved through
techniquesCommercial wind controller
voices:◦Unmapped expressive controllers
(CC#s)◦One Sample (single timbre) across
eight octave register◦Simple changing from velocity driven
(keyboards) to breath driven.

Solution with ExperimentationGoal: Create and Use a custom
sample that addresses these issues.
Attempt: A voice that used classical and acoustic guitar samples.◦Samples were chosen from the
Fantom-XR’s built in collection.◦Timbres were chosen to blend – or
compliment – a classical guitar.
![Page 24: A Breath in an Electronic World: Experiments in Musical Expression using a Midi Wind Controller Matthew Ahrens Mentor: Dr. James Bohn Bridgewater State.](https://reader030.fdocuments.us/reader030/viewer/2022032604/56649e5e5503460f94b583f4/html5/thumbnails/24.jpg)
Making the PatchSamples were cross faded to
create artificial registers. Acoustic guitar sample is only
voiced in the classical guitar’s harmonics timbre.
Centroid – jargon term for average brightness of a sound – was used as the determinant for matching the samples.
Result: a voice with a timbre and feel unique to both guitar and wind emulation.

Composition and RecordingBlend: For EWI and Guitar
◦Cuente el Arroz Chromatically heavy to show dissonance
and resolution between an acoustic instrument and an electronic one.
Interweaving lines to show both parts as supporting to each other.
◦Ping! Guitar part only uses natural harmonics. Shows timbre differences capable with a
expressively programmed voice.
