TECH 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.
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
- time stretch from 25 to 400% ratio (calculation time can be really long).
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.
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.
NOTE: The highest hierarchy part overrides the lower parameters (BIAS).
INTERFACE: many submenus, interface is not intuitive but after a while you get the idea :=)
FILTER multimode resonant filter: lowpass, highpass, bandpass + keyfollow option.
ENVELOPE 2 EGs:
- EG1 TVF: 4 segments + 4 times
- EG2 TVA:
4 segments + 4 times.
features some typical envelope presets to go e.g. piano, organ, brass, percussion, strings..
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.
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).
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.
