Korg | Prototype One


The Prototype one is a two tiered electronic keyboard organ which featured 49 keys on both keyboards. It was Korg's first real entry into the keyboard World. It featured built in effects like chorus and vibrato, as well as a joystick.

Google translated story from Korg Japan: (Will fix it another time)

49 Upper side monophonic of the two-stage keyboard key, polyphonic addition lower side to monophonic. In addition, at the same time hold the two keys in the upper side and the middle sound comes out. As a result, for example, or hold down two of the keyboard next to each other and a quarter note (quarter-tone) is put out, it was able to put out depending on the combination to more subtle intermediate sound.

Upper side is basically used to select the tone from the preset programs. There are 26 tone presets, tone piano in it, clarinet, tone and a tone for the Japanese instrument called the shakuhachi and shamisen, such as violin, I, U, E, the human voice of the vowel that O has been included. In addition, it has portamento.

Lower side, seven certain basic sounds (singing was called sustainable system three, brass-based one, percussion-based three) original sound-making that is processed from the one in the Pick "Traveler" * mechanism that can be.

Now that the view is standing way back to the electronic musical instrument dawn. The monophonic instrument has differential sound with portamento feature. It can make new sounds such as the shakuhachi, shamisen, or a tone like a human voice that was achieved by a technique such as non-linear synthesis. 

Chorus and built-in effects such as vibrato, also a joystick, which is also carried over to the current models equipped. This synthesizer was the lead to the current form was already born in Korg this time.

Thereafter, the contents to develop, combo organ known as Dekakorugu with an emphasis on organ function and (trade name KORG), commercialized mainly differentiate into synthesizer Minikorg 700 with an emphasis on sound synthesis function. Traveler filter was also a freature of the model, string, percussion, etc., Korg own specifications and naming that had been installed in the prototype one Unit was inherited as it is.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
