User manual YAMAHA PDP-300

[. . . ] SPECIAL MESSAGE SECTION PRODUCT SAFETY MARKINGS: Yamaha electronic products may have either labels similar to the graphics shown below or molded/stamped facsimiles of these graphics on the enclosure. The explanation of these graphics appears on this page. Please observe all cautions indicated on this page and those indicated in the safety instruction section. ENVIRONMENTAL ISSUES: Yamaha strives to produce products that are both user safe and environmentally friendly. [. . . ] The MEDIUM setting produces a fairly "standard" keyboard response. This setting is automatically selected whenever the power is turned ON. The SOFT setting allows maximum loudness to be produced with relatively light key pressure. To select a touch sensitivity setting hold the [MIDI/ TRANSPOSE] button and press the [REVERB] button a few times until the REVERB indicator corresponding to the desired setting lights: PEDAL = HARD ROOM = MEDIUM HALL = SOFT PITCH CONTROL Pitch control makes it possible to tune the PDP-300 over a ±50-cent range in approximately 1. 2-cent intervals. A hundred "cents" equals one semitone, so the tuning range provided allows fine tuning of overall pitch over a range of approximately a semitone. Pitch control is useful for tuning the PDP-300 to match that of other instruments or recorded music. Tuning Up 1. To tune up (raise pitch), hold the A-1 and B-1 keys simultaneously. Each time a key in this range is pressed the pitch is increased by approximately 1. 2 cents, up to a maximum of 50 cents above standard pitch. Release the A-1 and B-1 keys. Tuning Down 1. To tune down (lower pitch), hold the A-1 and A #-1 keys simultaneously. Each time a key in this range is pressed the pitch is decreased by approximately 1. 2 cents, up to a maximum of 50 cents below standard pitch. Release the A-1 and A#-1 keys. To Restore Standard Pitch* 1. To restore standard pitch (A3 = 440 Hz), hold the A-1, A#-1 and B-1 keys simultaneously. Release the A-1, A#-1 and B-1 keys. * Standard pitch (A3 = 440 Hz) is automatically set whenever the [POWER] switch is turned ON. For Pitch Control (A-1 + B-1/A-1 + A # -1) For Pitch Control (C3 ~ B3) For Transposition (F#5 ~ F#6) 7 MIDI FUNCTIONS A Brief Introduction to MIDI MIDI, the Musical Instrument Digital Interface, is a world-standard communication interface that allows MIDI-compatible musical instruments and equipment to share musical information and control one another. This makes it possible to create "systems" of MIDI instruments and equipment that offer far greater versatility and control than is available with isolated instruments. For example, most MIDI keyboards transmit note and velocity (touch response) information via the MIDI OUT connector whenever a note is played on the keyboard. If the MIDI OUT connector is connected to the MIDI IN connector of a second keyboard (synthesizer, etc. ) or a tone generator, the second keyboard or tone generator will respond precisely to notes played on the original transmitting keyboard. The result is that you can effectively play two instruments at once, providing thick multi-instrument sounds. This same type of musical information transfer is used for MIDI sequence recording. A sequencer can be used to "record" MIDI data received from PDP-300, for example. When the recorded data is played back, the PDP300 automatically "plays" the recorded performance in precise detail. Note: Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI cables longer than about 15 meters, since cables longer than this can pick up noise which can cause data errors. Control Change Numbers Control Change data representing Soft/Sostenuto and Damper pedal operations is transmitted by the PDP-300 whenever one of these pedals is used. [. . . ] Cords should also be disconnected when there is a high probability of lightening and/or electrical storm activity. 10. This product may be equipped with a polarized plug (one blade wider than the other). If you are unable to insert the plug into the outlet, turn the plug over and try again. If the problem persists, contact an electrician to have the obsolete outlet replaced. Do NOT defeat the safety purpose of the plug. 3. Care should be taken that objects do not fall and liquids are not spilled into the enclosure through any openings that may exist. 11. Some electronic products utilize external power supplies or adapters. [. . . ]
