The document describes the Harmony Machine, an intelligent pitch shifter that produces one or two harmony voices from a monophonic input signal. It has 44 preset harmony scales across four musical styles, 12 chromatic presets, and 8 detune modes. Users can switch between presets and keys instantly using the footswitch or MIDI control to change harmonies within a song. The Harmony Machine produces natural-sounding harmonies that stay within the key and scale of the selected preset.

CONCEPT OPERATION
OF
The Harmony Machine will produceone or two harmonyvoices which follow your playing. The
harmonynotesare realistic sounding,and are determined the carefully programmedfactory
by
presets four musical styles:Rock, Blues,Jazz andCountry.
in
Its internai computerrecognizes pitch of the input note, and its SmartHarmony plays the har-
the
mony voices so that they stay within the key and scaleof the Presetyou have selected.Both the
quality of the harmonypartsand its ability to play harmoniesin key make the Harmony Machine
vastly superior "unintelligent"
to pitch shiftingdesigns.
The Harmony Machine has44 different diatonicpresetharmonyscales,12 chromatic(parallel)
harmoniesthat work in any key, and 8 detunemodes.Using the includedFS-304footswitch and the
Harmony Machine'sspecialrandomaccess feature,you can switch betweenpresetscalesand change
keys instantly while performing,to cover shifting harmonieswithin a song.

BASICOPERATION
TU NI NG For bestresultsin creatingharmonynotes,your instrumentshouldbe tuned
to the Harmony Machine. The Harmony Machine will function as a very ac-
curate(A=440) tunerif you pressthe TUNING key unril the LED's display
rrA4rt
"40". When you play a note,the KEY display will show you the
nameof the note.In the PRESETdisplay, you will seetwo lines üat will
move as you play. The lines lie flat on the bottom when thereis no signal,
and will be straightup and parallel when the input is perfectly in tune.
If your note is flat, the lines will go to the left, and if you are sharp,they will
go to the right. If your input signal is overdriving the Harmony Machine,
they will go horizontalon the top of the display.If this happens, turn down
the INPUT LEVEL control or your instrument. When using the tuning func-
tion bóth the Harmony oulputsare muted. This allows you ro check your
tuning onstagewithout being heard.

patches.The DETUNE is gorgeous fatteningup polyphonic
for
stringsand thin FM patches.DETUNE can enhance realismof
the
synthpiano patch by simulatingthe inharmonicityof the upper
partialsof a piano string.
H OR N S Gives you a sectionalsoundüat plays along with your improvisa-
tions. Experimentwith different factory presers get a different
to
feel on the scaleaccidentals.Different factory presetscaleshandle
their "voice leading" in different ways. Octavesare nice for doubled
soloswhen you alreadyhave a bandplaying densechordsbehind
you.
votcE Closevoicings without too many high intervalswork best. Vocal
soundsand wordlessvocals are fabulous,as are Doo-wop style
grooves. Distinct lyrics a¡e bestkept to close,lower harmonies.
Ideal for a duo with a lead singerwith the other singerplus Har-
mony Machine doing trio back-ups.Try purting exrrareverb and/or
echoon the Harmony oulputsonly, to put them into the background
behindyou.
