For sale: Mo' Phatt rack module in excellent condition for its age. Includes Phatt ROM, rack ears, and IEC power cord. Everything works as it should. Installed a brand-new encoder to ensure this unit functions flawlessly well into the future. Updated to the latest OS (2.26).

Please examine all photos carefully, as we've done our best to document the condition with the photos. Of note, there are the usual battle scars on the black chassis, some minor scratching on the LCD bezel which is difficult to photograph, a blemish on the top right of the faceplate, and a bit of rack rash on the ears. Overall a very clean unit for it's age, but not mint.

Technical specs

We strive for accuracy, but errors can occur. Please verify details or contact us with questions.

Synthesis Type: Sample-based synthesis with E-MU Z-plane morphing filters, supporting layered voices, modulation routing, and effects optimized for hip-hop, R&B, and electronic production.
Polyphony: 64-voice polyphony; monotimbral operation on a single MIDI channel (one active part at a time).
Sound ROM (Mo’ Phatt): Factory-installed Mo’ Phatt ROM featuring genre-focused instruments and kits:
- Content: Hip-hop, R&B, dance, and urban-oriented sounds including drum kits, basses, synth leads, pads, hits, and FX.
- Drum Kits: Multiple genre-specific kits with non-General MIDI drum mapping for flexible sequencing.
- Layers: Up to 4 layers per preset for complex, evolving sounds.
Filters: Z-plane digital morphing filters derived from the E-MU Morpheus:
- Types: Low-pass, high-pass, band-pass, band-reject, and vocal/formant-style filters.
- Behavior: Resonant, morphable filters with smooth transitions.
- Per-Layer Control: Each layer has its own filter, envelope, and modulation routing.
Effects: Dual stereo 24-bit effects processors with multiple algorithms:
- Includes: Reverbs, delays, chorus, flanger, and distortion effects.
- Routing: Insert-style effects (not send/return); shared across the active preset.
- Limitation: Only two effects processors available at once.
Modulation:
- PatchCord System: Extensive modulation matrix allowing routing of controllers, LFOs, and envelopes to synthesis parameters.
- LFOs: Multiple LFOs per voice with selectable waveforms and MIDI sync.
- Envelope Generators: Dedicated filter, amplifier, and auxiliary envelopes per layer.
- Performance Control: Velocity, key tracking, and MIDI controllers can modulate pitch, filter cutoff, amplitude, pan, and effects.
Memory: Factory ROM presets plus user-editable RAM presets; supports saving custom sounds and edits (no multisetups due to monotimbral design).
Control & Interface: Front-panel data wheel and buttons with LCD display; deep editing via menu navigation or computer-based editors.
Connectivity:
- Audio Outputs: Stereo 1/4-inch outputs.
- MIDI: MIDI In, Out, Thru (single MIDI channel operation).
- Digital Output: S/PDIF stereo digital output.
- Power: External DC power supply.
Physical Design: 1U rack-mountable metal chassis; compact and lightweight, suitable for studio racks or live rigs.
Sound Character: Punchy, modern, and rhythm-focused; widely used for hip-hop, R&B, and electronic genres with a signature late-90s / early-2000s E-MU sound.
Limitations: Monotimbral operation (single MIDI channel); smaller display requires menu navigation for deep edits; no USB-MIDI; non-GM drum mapping may require manual sequencing adjustments.
