FS1R Editor


This software is the tone editor for YAMAHA Synthesizer FS1R.

The FS1R actually integrates two tone generation concepts for extraordinarily broad voicing versatility.
Although based on YAMAHA's developed Formant Shaping synthesis technology and FM (Frequency Modulation) Synthesis.

Formant Shaping synthesis gives musicians unprecedented capability to produce and control sounds with characteristics
and flexibility similar to that of the human voice.
It can also produce instrument voices that have the response and rich pitch-dependent timbral variations.
FS technology also lends itself ideally to FM synthesis, similar to the type introduced in the legendary
YAMAHA DX and TX-series synthesizers.

FS1R can create anything from totally new simulations of human vocal sounds to
classic DX electric piano voices, and anything in between.

- Operation of all the parameter was enabled from PC.
the user interface which can perform making sound conveniently.

- This software can save SMF (Standard MIDI File) so that voice data can also be passed to the Mac users and Linux user, etc.

- Since there was software which can make FSEQ data from overseas software "FSeqEdit",
the file(.syx) is read and it enabled it to store in a FS1R.
Thereby, Formant data was made from the WAV file etc.,
and FS1R was made to talk and it became possible to give width to tone creation.
Furthermore, since FSEQ data is convertible for SMF,
it is possible to also distribute FSEQ data to the direction of other OS's.
