Roland MBD-1
Bass & Drums Sound expansion (1995)

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.

RACKMOUNT 1 unit module with 11 buttons and a 7-segments display.

Rear panel terminal connectors:
- Midi interface
- main signal output
- signal line input (signal not processed)


Front panel terminal connectors:
- headphones

 

 

TECH core 16 bits microcontroller HF6415108F (part of HD6415 - h8 / 510 / 500 family) manages 28 voices polyphony. MVS1 synthesis is based on PCM rompler subtractive synthesis and each patch is composed by 1, 2, 3 or 4 PCM samples layers.

The MVS1 module is more like a preset machine: all sounds are ready to go and it not possible to deep edit parameters from direct panel - most functions s can be changes only using an external Midi SYSEX strings generator.

 

WAVETABLE the 16 MB internal ROM contains 255 PCM samples at 16-bits resolution focused on drum CD-ROM collection from Spectrasonic but also some new recorded performances like bass licks, slide, picked.

MBD1 board features many acoustic drumkits and basses recorded by famous artists like Marcus Miller, John Patitucci, Bob Wilson or Abe Laboriel. hear bass and drums samples

 

 

PERFORMANCE Module is multitimbric and handles 7 parts + 1 drum.

Each part can be set with a single patch with variable multitimbral parameters: - reverb and chorus level amount - volume amount - stereo panning amount - pitch detune - Midi channel assign - keyboard zone assign

 

FILTER section is based on digital TVF - Time-Variant-Filter - and 3 modes:

- lowpass - bandpass - highpass HEAR filter sweep

 

LFO 2 modulators features 7 shapes: triangle, sinewave, sawtooth, trapezoidal, random, sample & hold and a variation called chaos random.

Modulator destinations are: - LFO 1: amplitude - LFO 2: filter hear LFO sample and hold on filter

ENVELOPE each layer features 3 EGs:

- EG1 amplitude: 4 stages ADSR - EG2 filter: 4 stages ADSR - EG3 pitch: 4 stages ADSR

EFFECTS the module manages:
- 3 X choruses
- 8 X reverbs
- 2 X delay.
TECH: This section also cannot be edited or applied to a specific multitimbral part but to master out.

 

MEMORY:
- 17 performances
- 255 patches
- 8 rhythm sets
- 1 global system setup.
TECH: There is no patch RAM slots but machine can bulk dump data to Midi exclusives.

- LEFT - Settings memory system works with a common CR-2032 in a holder.   - CLICK TO ENLARGE -
