Reference excerpt

The Roland DJ-70 is a 16-bit linear A/D Conversion & 20-bit linear D/A Conversion sampling workstation and was released in 1992 by Roland Italy.

Roland DJ-70MKII The Roland DJ-70MKII was released in 1996 by Roland Italy. It had 37 keys, 8 Play Pads (Pitchbender Joystick and featured the first ever for DJ's a Special Scratch Dial/Scratch Pad), 24 Voice Note Polyphony, 8 Track music sequencer, with RPS/BPM Function and featured a 3.5"in. floppy disk drive (2DD/2HD), "Load-While-Play" feature, SCSI port only on Roland DJ-70MKII. It also had a large backlit LCD screen. The Roland DJ-70MKII with its more powerful features then the Roland DJ-70, was essentially a Roland S-760 rack mount sampler with a keyboard.

Sample Rate Up to 32 samples can be recorded. The Sampling Frequency Rates can be used are 16-bit 22.05 kHz or 44.1 kHz. Roland DJ-70 & Roland DJ-70MKII both can read on 3.5" floppy disk drive (2DD/2HD) file from Roland S-50 Sampling Keyboard, Roland W-30 Sampling Keyboard, Roland S330/S550/SP-700/S770/S750/S760 rack mount sampler (Using CONVERT LOAD feature). AKAI S1000/1100 sounds via 'SCSI port (Roland DJ-70MKII only)'. Roland DJ-70: • Memory 2MB [Sample Time: 22.5 sec.(44.1 kHz) Stereo. 45 sec.(22.05 kHz) Mono.] • Memory 4MB [Sample Time: 45.3 sec.(44.1 kHz) Stereo. 90 sec.(22.05 kHz) Mono.] Roland DJ-70MKII: • Memory 2MB [Sample Time: 22.5 sec.(44.1 kHz) Stereo. 45 sec.(22.05 kHz) Mono.] • Memory 32MB [Sample Time: 6 min.(44.1 kHz) Stereo. 12 min.(22.05 kHz) Mono.] Both Roland DJ-70 & Roland DJ-70MKII use RAM Memory type, there are two slot available. Type used are (30-pin for MKI) 72-pin SIMMs Memories.

Display Main panel features a 64 x 240 pixels backlit display LCD screen.

Worked examples

Example 1 — a first encounter with Roland DJ-70

Start with the simplest possible case. Write down what Roland DJ-70 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Roland DJ-70 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Roland DJ-70 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Roland DJ-70

In research: Roland DJ-70 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Roland DJ-70 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Roland DJ-70 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital synthesizers, Electronic musical instruments, Hip-hop production, so understanding it makes those chapters shorter.
In everyday life: Look for Roland DJ-70 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
