ZEEEDIT

ZeeEdit-FS1R is a MIDI editor for the Yamaha FS1R synthesizer. It is a computer program which communicates with the device over MIDI: it enables the synthesizer parameters visualization and direct edition on your computer screen... You should not edit anything on the device itself anymore. That's because the computer keeps the device state and memory content to avoid waiting times (cache memory). It must be the center point of any change. If you do some editing on the hardware, the computer will not be aware of it and displayed information may not be relevant anymore.
