All new product supports the new Little Phatty/Slim Phatty OS 3.1 features!

The VST-AU Little Phatty Editor™ is a real-time MIDI Synth Editor that allows you full control of every parameter of the sound on the Moog Music Little Phatty™ and Slim Phatty™ synthesizers. With it, you can view, manage and edit all your Patches with detail on the computer, visually. All parameters are fully automatable in your favorite VST or AU Host (see product web page for current Host support), giving you the ability to visually program the Little Phatty or Slim Phatty to your music via the Host sequencer. This ability to model your Synth Patches in real-time, inside your main music production environment is part of what makes the VST-AU Little Phatty Editor™ unique when compared to other hardware Synth Editors. If you don't need or use a DAW Host, you can still manage the Patches with the Standalone version. The VST-AU Little Phatty Editor™ is developed and supported by reKon audio (

Complete Synth Editor

The VST-AU Little Phatty Editor™ is a visual editor allowing you to view and edit every parameter of a Little Phatty or Slim Phatty Patch and supports the all the latest Little Phatty OS version 3.11 parameters.

Advanced Patch Librarian

The VST-AU Little Phatty Editor™ includes an advanced 'Patch Manager' view that allows you to rename and arrange Patches to create your Bank. Drag and drop Patches where you want them with a complete overview of the Bank in either Swap, Copy, or Move mode. You can load and save your Patches and Banks as standard .FXB/.FXP files.

Patch Randomizer

The VST-AU Little Phatty Editor™ also includes a 'Patch Randomizer' that allows you to easily create randomly generated Patches.

MIDI Input and Output Monitoring

The 'MIDI Monitor' view allows you to view all MIDI data coming into and out of the VST-AU Little Phatty Editor™ for both the Host and Editor MIDI data paths. Easily switch between Host and Editor views. You can even copy the data from the event logs for pasting and saving into standard text editors or other applications.

MIDI Setup

The VST-AU Little Phatty Editor™ is based on an entirely new framework that allows you to select the MIDI input and output ports and channels directly from within the Editor itself. This allows you to send and receive MIDI data directly to and from your Synth. You are no longer limited by any Host MIDI incapabilities. 'MIDI Setup' also allows you to filter out specific MIDI data for both Host and Editor MIDI data paths or toggle MIDI In and Out operations.

Little Phatty OS Firmware: The VST-AU Little Phatty Editor™ requires LP OS 3.11 firmware or later to run properly.
