The Fatty 311 Black Friday deal is 50% off, taking Soundiron's vintage electro organ library for Kontakt to $14.50 until Dec 6, 2026.
Fatty 311 is a Kontakt library built around the Conn Prelude 311 organ. Soundiron sampled its sustains, staccatos and effects in three microphone positions to give your MIDI a real instrument to lean on.
The maker describes the sound as beefy, warm and analog, and says it can cut through any mix. The 1970s wooden-cabinet look is part of the instrument's character too.
It is a home electric organ from C.G. Conn Ltd., an American company incorporated in 1915 and based in Elkhart, Indiana. Conn started out with brass instruments, and by the 1950s the electric organ was its best-seller.
The Prelude has these parts, according to Soundiron:
Conn went bankrupt after the household organ craze faded, and Steinway bought the company in 2000.
The core content is organ sustains, releases, staccatos and SFX at Close, Mid and Far mic positions. The synth voices include Clarinet, Trombone, Violin, Guitar Tremolo, Diapson, Flute, Reed and Major Bass.
Soundiron also added 20 custom sound-designed FX and ambient presets, made from the source organ. In all there are 21 Kontakt.nki instrument presets.
The samples are 24 bit / 48 kHz uncompressed PCM wav files: 8,700 stereo samples that take 6.17 GB once installed.
The multi-layer interface gives you LFO, filter, glide and arpeggiator controls. Vibrato is built in, and a special "Octave" knob rolls lower and higher octaves into the tone.
A modular FX rack sits at the bottom of the interface. It holds 27 DSP effect modules, and you can load them into any of 8 slots in any order.
The modules include:
The convolution reverb carries 99 rooms, halls, chambers and outdoor spaces, plus 40 custom FX impulses for more extreme sound design. A bank of factory FX rack chain presets gets you started.
Fatty 311 runs on Windows 7 or higher and Mac OSX 10.12 or higher. It needs a dual core CPU and 2 GB of system RAM, and a SATA or SSD drive is recommended.
You need the full retail version of Native Instruments Kontakt 6.2.2 or newer. The free Kontakt Player and the Add Library import process do not support this library.
Soundiron says the library covers everything from an old video game sound to a huge synth bass tone to playing straight from the hymnal.
