FM Voice Editor

The Yamaha FS1R's 8-operator FM and Formant Synthesis engine is complex, but Patch Base makes it much easier to work with. The Voice Editor shows you the layout of the currently selected algorithm and gives quick access to every voiced and unvoiced operator.

Visualize the current FM algorithm
Copy/paste the settings for entire operators
Copy/paste envelopes for quick editing
Dynamic controls show the relationships between different Spectral Form (waveshape) settings, and ratio settings
Easy viewing and editing of the Formant and FM knob destinations, to make your patches more playable

Performance Editor

The FS1R can play up to 4 parts at once via Performances. Patch Base shows you the entire Performance in one place for easy editing of sound selection, mixing levels, effects, control routing, MIDI channels and more. Quickly create a multi-layered Performance for big sounds, or a multi-channel performance to play multiple parts using the FS1R's 4 parts.

Quickly browse and select from the hundreds of presets on the FS1R, and your own internally saved sounds
Easy high-level control of sound customization: tuning, envelope alterations, LFO settings, and more
View and edit all of the FS1R's Reverb, EQ, Variation, and Insert effects in one place. Controls are dynamically updated based on the currently selected effects.
Clear views of the 8 voice control routings (modulation matrix) in an FS1R Performance. Route external MIDI controls and the FS1R's front-panel knobs to dozens of voice parameters on any of the parts. Simple.

Bank Editors
