What is „FM“?

FM is the abbreviation of Frequency Modulation.

Here oscillators are modulated by other oscillators – their amplitude and frequency then characterizes the sound.

The FM synthesis was developed in 1967 by the american scientist Prof. Dr. John Chowning at the Stanford University and was made public in 1973. One year later the Yamaha Corporation bought the patents on this revolutionary synthesis system.
In 1983 the Yamaha DX7 was introduced and put the synthesizer world upside down, leaving synthesizer legends like Moog or Oberheim behind.
Countless music productions featured the all new sound of the DX7 – having its strengths in unique E­Pianos, Synth Basses, Harps, Organs, and metallic sounds. The dynamic range of these sounds became the standard for all future digital sounds.
After the groundbreaking success of the DX7 the FM synthesis has found its way into a large range of Yamaha synthesizers like TX7, TX816, DX21, TX81Z, DX27, DX100, FB01, DX7II, TX802, V50, SY77, SY99, FS1R, DX200, PLG-150-DX, reface.



Sample-Partial-Programming (SPP) for expressive and dynamic FM-sounds

The multisamples were recorded in serveral dynamic levels for re-building the high dynamic of FM-synthesizer.
The original FM-sounds were not simply sampled 1:1.

EASY SOUNDS developed FM-partials, which were mapped as User Waveforms and combined to new FM-voices using up to 8 voice elements of MOTIF XS. The technique of  Sample-Partial-Programming (SPP) offers a very high flexibility allowing creative sounddesign. You don’t need to be an expert for making individual edits.

For the sample-production beside the legendary DX7 other FM-synths like SY99, FS1R, DX200 or FM8 were used.

Many of the delivered voices are towards to the classic DX7 Voices. They are giving the feeling playing a real FM-synth.

Impressive stereo-sounds are similar like the DX7II with the wide panning.

But based on different combinings of the FM-partials there are also many new sounds with independent character.

The following voice-types are included in FM Xpanded:

  • DX Electric Piano
  • DX Jazz Guitar
  • DX Clavinet
  • DX Organ
  • DX Straton
  • DX Harp
  • DX Flute
  • DX Brass
  • DX Horns
  • DX Strings
  • DX Bells
  • DX Harmonica
  • DX Synth Lead

The registrations are combining the FM voices with styles and preset voices. Beside classic keyboard-split-styles there are also registration banks with the CHORD FINGERING setting „FULL KEYBOARD“, which are very useful for companiments of vocals or solo instruments. You can also play jazzy chord progressions.
