Vocaloid Keyboard

Vocaloid Keyboard is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vocaloid Keyboard rather than just read about it. In short: Vocaloid Keyboard is a physical MIDI keyboard with a built-in Vocaloid synthesizer. The commercial product as a keytar was released in December 2017.

Key takeaways

Vocaloid Keyboard belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vocaloid Keyboard to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vocaloid Keyboard from memory before moving on to harder problems.

Reference excerpt

Vocaloid Keyboard is a physical MIDI keyboard with a built-in Vocaloid synthesizer. The commercial product as a keytar was released in December 2017.

About The Vocaloid Keyboard was designed using the VY1 vocal. It is part of the eVocaloid range, a LSI sound generator called the "NSX-1" source chip which can generate 30 sounds of midi. For VY1, it uses the NSX-1 chip "eVY1". The first prototype was showcased at INTERACTION by Information Processing Society of Japan, March 2012. The commercial prototypes as 37 key keytars with three colours; black, white and pink were officially showcased at several events in Japan, 2015. The keytars were able to be played at three Joysound's Karaoke in Japan in 2015. In 2015, green Megpoid version was also showcased at Think MIDI and purple Yuzuki Yukari version was featured in niconico live broadcasting by VOCALOMAKETS. The first commercial model VKB-100 was released in December 2017. VKB-100 won Good Design Award 2018. It was also selected as GOOD DESIGN BEST 100.

Worked examples

Example 1 — a first encounter with Vocaloid Keyboard

Start with the simplest possible case. Write down what Vocaloid Keyboard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Vocaloid Keyboard 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 Vocaloid Keyboard 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 Vocaloid Keyboard

In research: Vocaloid Keyboard appears in computer 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 Vocaloid Keyboard 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: Vocaloid Keyboard is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Electronic musical instrument stubs, Keytars, so understanding it makes those chapters shorter.
In everyday life: Look for Vocaloid Keyboard 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.
