KEYBOARD 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

SAMPLING main core based on a 16-bits CPU INTEL 80C196 which manages 24 voices polyphony.; DAC is a Burr-Brown PCM54HP and ADC Asahi Kasei 9201A with 2 fixed standard recording frequencies at 22,05 Hz or 44,1 kHz. Internal stereo sampling engine is based on MB87422 + MB87423A chips (same found on flagship S-770) works at 16 bits resolution. The hierarchy is basically the following structure: A Dj70 mk2 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 (yes complicated!)

SAMPLE IMPORT  it is possible to Midi sample dump or load-import (by disk) other Roland format e.g. S770, S750, W30, S550, S50 using a dedicated tool into utility section.  The SCSI adds a Akai S1000 / S1100 import file system (NOT SxX DISK! only SCSI)

Filter, envelope and LFO

FILTER digital multimode resonant filter (LPF, HPF and BPF) keyfollow option

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

LFO each partial features a single syncable delayed modulator (shapes: sine triangle, sawtooth up, sawtooth down, square, random, bend up, bend down).  Modulation destinations are: 
A- LFO to amplitude 
B- LFO to filter cutoff 
C- LFO to sample pitch

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)

Sequencer, memory & Storage

SEQUENCER  the RPS sequencer (Realtime Phrase Sequencer) features 8 tracks.  The mk2 adds a TEMPO functions which allows to TAP a loop frequency speed linked to the sample, this allow to sync all samples to a unique master tempo.

MEMORY  sampling 2 Mbytes factory expandable to 32 Mb using standard 72 pins SIMMS (1 mega each) for 512 samples + 255 partials + 64 performances. Special MEMORY WALL setting allows to split memory for LOAD-WHILE-PLAYING option. 

floppy disk drive format 3.5 DD/HD 1440 /720 Kb capacity with auto-boot.  
Floppies formatted in ROLAND proprietary file system as DJ-70 is not Ms-DOS compatible. It is possible to install a more modern USB emulator instead, we sometimes make some kit, please do verify our shop or contact US. SCSI allows to connect cdrom, hd and zip storage media.
