Roland DJ-70 (1992)
Sampling Workstation

 

A now totally forgotten sampler produced during the nineties by Roland Italy, launched as the "DJ" version of famous and professional module S-770/S-750.

The DJ-70 now deserves a right description on the net. Many people get fooled by the "easy" DJ approach, but the DJ70 is a quite complex machine with a LOT of advanced synthesis functions, sadly hidden in a not-so-obvious edit interface.

info KEYBOARD SAMPLER 61 dynamic keys.
Main panel features a 64 x 240 pixels backlit display,42 push buttons, a data encoder, 2 knobs, a pitchbender joystick and a special scratchpad that *should* emulate a vinyl scratching.

Rear panel terminal connectors:
- main signal out
- stereo input with gain trimmer (+ 4 dBm ~ 50 dBm)
- Midi interface
- display contrast trimmer
- pedalswitch sustain input

Side panel terminal connetors:
- Cue headphones preview with individual gain.

 

 


editTECH main core based on a 16-bits CPU INTEL 80C196 manages 24 voices polyphony.
The stereo sampling engine is based on MB87422 + MB87423A chips (same found on flagship S770) works at 16 bits resolution. DAC is a Burr-Brown PCM54HP and ADC Asahi Kasei 9201A with 2 fixed recording frequencies: 22,05 / 44,1 kHz.

SAMPLE STRUCTURE: a single DJ70 sample can be modified with various edit functions:
- loop (forward, backward, ping pong mode)
- pitch tuning
- smooth (crossfade)
- volume gain (normalize)
- cut, paste, truncate, trim, split
- resample to: 44,1 / 30 / 24 / 22,05 / 15 kHz frequencies
- time stretch from 25 to 400% ratio (calculation time can be really long).

DJ70 structure

 


edit SAMPLE IMPORT
it is possible to Midi sample dump or load-import other Roland format e.g. S770, S750, W30, S550, S50 using a dedicated tool into utility section, sadly sample import does NOT work very well and may take a while, mainly to process-data such as conversions from 12 to 16 bits.

 

DJ70 structure

 



edit
SAMPLE STRUCTURE the hierarchy is basically the following structure:

samples-> partial-> patch-> performance.

A partial is composed by up to 4 samples (each with own level, tuning, panning) then partial are assigned to keyboard zone (from 1 to 88) in a patch. Finally up to 31 patches can be assigned to a performance with an assigned channel.


Dj70 edit functions
NOTE: The highest hierarchy part overrides the lower parameters (BIAS).




edit
INTERFACE: many submenus, interface is not intuitive but after a while you get the idea :=)

dj70-tech


edit FILTER multimode resonant filter: lowpass, highpass, bandpass + keyfollow option.


TVF filter

 

edit ENVELOPE 2 EGs:
- EG1 TVF: 4 segments + 4 times
- EG2 TVA: 4 segments + 4 times.
EG TVA features some typical envelope presets to go e.g. piano, organ, brass, percussion, strings..

ENVELOPE TVA

 


edit
LFO each partial features a single syncable delayed modulator (shapes: sine triangle, saw up, saw down, square, random, bend up, bend down).

Modulation destinations are:
A- LFO to amplitude
B- LFO to filter cutoff
C- LFO to sample pitch.


LFO

 

edit RESAMPLING 2 samples can be combined in 6 algorithms (list) or structures same found on synthesizer module JD-990. These are pre-fixed audio patches that connect 2 samples into variable setups mixed with 3 audio elements: amplifier (TVA), filter (TVF) and ringmodulation (R).

edit
SEQUENCER the RPS sequencer (Realtime Phrase Sequencer) features 8 tracks.
The RPS is like a litte notepad for idea on the fly, since it does not contains edit functions like sync, quantisizer nor even a metronome.

MEMORY:
- 512 samples
- 255 partials
- 64 performances
- sampling 2 Mbytes factory, expandable to 4 Mb using standard 30 pins SIMMS (1 mega each).
TIP Special MEMORY WALL setting allows to split memory for LOAD-WHILE-PLAYING option.

REVIEW "Algorithms allow unlimited texturse and lofi, strange patterns and glitched sounds. Programming The DJ70 is quite difficult but challenging. You can do more than playing loops and ... RTFM!"
