Rackmount sound expansion series were budget version of SRJV cards fitted into expanders e.g JV-1080 / JV-2080.

The MBD-1 is basically the equivalent of the Srjv-10 bass and drums board a special cooperation with Spectrasonic.

The Roland M-BD1 Bass/Drum Sound Expansion module is a 1U rack (aftertouch and velocity sensitive), 28 voice (8-part multitimbral) digital synthesizer (editable via MIDI only), featuring an oscillator (255 samples), resonant low|high-pass filter, dedicated (4-stage) pitch, filter, and amp envelopes, dual LFOs (saw, sine, square, random, S/H, triangle waveforms with attack|decay), portamento, reverb/chorus, 197 presets, 17 rhythm sets, mix input, and MIDI.

A joint effort between Roland and Spectrasonics, this expansion module features a large quantity of electric/acoustic basses and acoustic drums.

The quality of these samples is outstanding, and with a bit of care during programming/sequencing, it is possible to achieve great realism.

The players involved are well-known session players - bassists Marcus Miller, Abraham Laboriel Sr., John Patitucci, Abe Laboriel Jr., and drummer Bob Wilson.

The board features single-note programs, that you can play from a keyboard, and also some prerecorded loops, to sync with your sequencer. A must for rock, jazz, fusion, world, Latin, and other acoustic 

genres.
