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 proper description on the net. 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 37 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.
Stereo sampling engine is based on MB87422 + MB87423A chips (same found on flagship S-770) works at 16 bits resolution.

sample DAC is a Burr-Brown PCM54HP and ADC Asahi Kasei 9201A with 2 fixed standard recording frequencies:
- 22,05 Hz
- 44,1 kHz

demo HEAR resample 44 -> 15 kHz




editSAMPLE EDIT
a single DJ70 sample can be modified with various edit functions:

sample - 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




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.

DJ70 structure



NOTE: sample import does NOT work very well, buggy and sluggish. It may take a while, mainly to process-data such as conversions from 12 to 16 bits.




 

edit SAMPLE STRUCTURE the hierarchy is basically the following structure:
samples-> partial-> patch-> performance.

Dj70 edit functions - LEFT -A Dj70 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.

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

FILTER multimode resonant filter + keyfollow option

TVF filter

Filter Modes:
- lowpass
- highpass
- bandpass
demo HEAR Lowpass


edit ENVELOPE 2 EGs:

ENVELOPE TVA - 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 ...


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

LFO

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

demo HEAR LFO shapes





edit
RESAMPLING 2 samples can be combined in 6 algorithms 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.
