Compact organ module with nine drawbars, six dials and included MIDI cable bundle

RME

RME B4000+ MIDI Sound Module with Cable Bundle

SKU CH-AJMQ-50FXY

Authentic Hammond B3 organ emulation with 91 tonewheels, nine drawbars, Leslie simulation and dual MIDI ports for upper and lower manuals

  • Authentic Hammond B3 tone recreated via 91 tonewheel simulation
  • Hands-on control with nine physical drawbars and six parameter dials
  • Realistic key click and contact delay for genuine organ feel
  • Supports three manuals — upper, lower and pedal — from one unit
  • Two keyboards connect directly to MIDI ports without extra merger

Authentic Organ Sound Module

The Ferrofish B4000+ recreates the Hammond B3 organ using a Sharc DSP to simulate all 91 tonewheels with crosstalk and mechanical wear. It delivers fully polyphonic sound with scanner vibrato, tube amp emulation, reverb, and a Leslie speaker simulation. Nine physical drawbars and six dials provide hands-on control over the organ voice.

MIDI Expansion for Dual Manuals

Two keyboards connect directly to the MIDI ports without a separate merger, enabling independent upper and lower manual performance. The module also supports a third pedal manual for a complete organ setup. This replaces the need for a bulky vintage instrument and a complex MIDI routing chain in a single compact unit.

Organ Players Seeking Hardware Control

This module suits keyboardists who want dedicated drawbar control and authentic B3 emulation without a computer host. Players requiring built-in audio outputs beyond the described simulation or those needing extensive synth engines beyond organ tones should consider alternative sound modules.

Questions about this item

What MIDI connections does the B4000+ provide for hooking up two keyboards?

The module has MIDI ports that accept two keyboards directly for upper and lower manuals without a separate merger.

What is the critical step when connecting the bundled cable to the MIDI ports?

Insert each plug fully until it clicks; a loose fit will break the data link and silence the organ sound.

Which internal component simulates the 91 tonewheels and may need a firmware update later?

The Sharc DSP handles all 91 tonewheels; check the maker’s site for firmware that refines the emulation.
