Will Systems | MAB-303


Although you could do more with it, the MAB-303 is strictly a TB-303 emulator. It succeeds at emulating the sound and character of the 303 better than most. This may be because it is analog and not virtual emulation technology. It is a half-rack desktop or rack-mount module which houses a nice analog VCO synth engine complete with 303-like controls and knobs. Front panel knobs control basic but familiar parameters: waveshape, VCF cutoff, resonance (Q), EnvMod, Accent and volume.

The MAB-303 brings the 303 into the '90's with a few added features. First there is a new waveform to play with - pulse. The MAB-303 has MIDI implementation which applies to some parameters. The knobby-controls are not MIDI'd (argh!) however the following new features are MIDI controllable: LFO, pitch mod, pitch bending, MIDI velocity and auto glide.

Sound wise, it makes a convincing 303. It isn't as squelchy in the self-resonance area however its many new features should more than make up for that. The MAB-303 works very well with a MIDI sequencer (there is no built in sequencer unlike the original) and although the Env Mod, CutOff and other front panel controls can't be controlled by MIDI the MAB-303 makes it easier for new and experienced users to use a 303-type synth in a modern studio environment.
