Fatsondo

Fatsondo has been tailor made for the creation of fat sounds. It has a built-in chorus, flanger, stereo delay, comes with 64 factory patches and a 17 page manual (Adobe Acrobat).

Features
Fatsondo is a powerful synthesizer with many programming options. The main features are a polyphonic unison mode, a unique processor module, which can switch between different functions, a warm and resonant lowpass/highpass filter, 3 oscillators per voice (which can be extended with the unison function) and built-in effects.

Oscillators
Fatsondo has 3 oscillators per voice, which can be further multiplied using a unique polyphonic unison mode. For example, you might create a patch, which is based around 3 oscillators. Then the Unison section can be used to go one step further and multiply these settings, creating even more multiples of these, say 6 or 9 oscillators per voice. Each group can further on be detuned. Thus, the detune slider works as a detuning setting for each group of the three oscillators. However, the synth is quite powerful even without this nice feature. Incredibly thick and fat sounds can be created using just say 2 or 3 oscillators per voice in combination with say the envelope controlled flanger, the chaos oscillator or some of the processor's filter banks.

Resonant Lowpass Filter
There's a traditional resonant lowpass/highpass filter, with an envelope, in Fatsondo. As in most synths, it has settings for cutoff and resonance etc, but in addition it also features an LFO of its own. It can be used to modulate the cutoff frequency.

Multi mode Processor
Fatsondo contains a unique processor, which can switch between different functions such as formant filters, filter banks, a chaos oscillator, ring modulation and pitch shifting etc. The processor can be modulated using its dedicated envelope. For odd effects, the envelope can be inverted. The processor module can also be modulated using Fatsondo's Performance Keys.

Performance Keys
With the Performance Keys, the user can play the characteristics of the processor. For example, if the processor operates in filter bank mode, then the sound of the filter bank can be modulated by playing the keys on the lowest octave of the keyboard. If you're capable of playing with both of your hands, then you can modulate the processor by pressing these keys with your left hand and performing a solo with your right hand. Or you can program the performance keys in your sequencer afterwards of course.

Built-in Effects
On top of all these features, the synthesizer has built-in effects, which can be programmed for each patch. The effects are chorus, flanging and stereo delay. The flanger has its own LFO, but if the processor is switched to flanger mode, flanging can be controlled by the processor's envelope.
