The Yamaha FS1r is Yamaha's most advanced hardware FM synthesizer, featuring a combination of 8-operator FM and formant synthesis. It is capable of producing sounds similar to the DX7, vocoder-like Human vocal sounds, and everything in-between. It can load SysEx dumps of Yamaha DX7 patches and reproduce them, but with less DAC noise.
It has a very complex interface and can be very challenging to program, even with a software editor (Yamaha included a custom FS1r-only version of SoundDiver with the unit). It was not very popular during its initial production run and was discontinued after being on the market a short time. It later became much more popular and used units often sell for more than the original new retail price.
We've made the SoundDiver FS1r OEM version that shipped with the unit available below, but since it was intended for use with Windows 98, it may not run properly on a modern Windows system (we couldn't get it to run on Windows 7, but it ran fine on a Linux machine via Wine).
