FM Xpanded - Synth

These are the sounds that made music history!

Yamaha's FM technology was the foundation of the famous DX7 synthesizer. The electric piano sound alone is one of the most recognized instrument sounds from the 1980's. Easy Sounds has taken this classic technology and created the ultimate retro pack for your Yamaha Motif synth.

Here's more from the developer of the pack, Peter Krischker:

The soundlibrary FM Xpanded offers sample-based FM-sounds with highest dynamic and authenticity. It includes DX-oriented sounds as well new and innovative sound creations.

FM Xpanded constist of serveral volumes
The first volume "Electric Piano & Clavinet" includes 64 Voices, 24 Performances and 128 MB Samples.
Many E-Pianos and Clavinets are based on the classic DX7 Voices. It is like playing a real FM-synth.
Impressive stereo-sounds are similar to the Yamaha DX7II with the wide panning.
But based on different combinations of the FM-partials there are also many new keyboard sounds with independent character. You will find several "Hybrid Sounds" combining conventional electric pianos with FM-partials.
The voices and performances of the first volume "Electric Piano & Clavinet" are not only useful for conventional or contemporary music. There are also trendy keyboard sounds using the MOTIF XS effects and filter, which fit to many trendy music styles. For demonstrating this some drumloops in WAV-format and keyboard-sequences in Standard MIDI File format are included. They can be combined to a small pattern with two tracks.
The 24 Performances include impressive Stereo Keyboard Layer Sounds combining two or more voices.

Important Information:

• MOTIF XF: The soundset can be loaded to pre-installed SDRAM or to the optional Flash Memory (Flash Memory Expansion Module FL512M or FL1024M).


• MOTIF XS: For loading the soundset the installation of optional DIMMs (2 x 128 MB or more) is needed.


• MOTIF XS: For loading the soundset the installation of an optional Flash Expansion Memory Module (FL512M or FL1024M) is needed.

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-to-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.

What is FM?
FM is the abbreviation of Frequency Modulation. Here oscillators are modulated by other oscillators – their amplitude and frequency then creates unique sounds. 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.The last device from Yamaha using FM was the plug­in board PLG150­DX which can be installed into host synthesizers like the MOTIF ES, MOTIF-RACK ES, or S90 ES.
