User manual YAMAHA PDP-100

[. . . ] We sincerely believe that our products and the production methods used to produce them, meet these goals. In keeping with both the letter and the spirit of the law, we want you to be aware of the following: Battery Notice: This product MAY contain a small nonrechargeable battery which (if applicable) is soldered in place. The average life span of this type of battery is approximately five years. When replacement becomes necessary, contact a qualified service representative to perform the replacement. [. . . ] The voice corresponding to the voice selector pressed first will be reproduced at a slightly louder volume than the second voice. Polyphony in the DUAL mode is as follows: Notes/voice 16 + 16 8 + 16 Polyphony 8 5 TRANSPOSITION The Transposition function makes it possible to shift the pitch of the entire keyboard up or down in semitone intervals up to a maximum of six semitones. "Transposing" the pitch of the PDP-300 keyboard makes it easier to play in difficult key signatures, and you can simply match the pitch of the keyboard to the range of a singer or other instrumentalist. The [MIDI/TRANSPOSE] button and keys F # 5 through F#6 on the keyboard are used for transposition. Press and hold the [MIDI/TRANSPOSE] button. Press a key between F #5 and F#6 according to the desired amount of transposition. * 3. Release the [MIDI/TRANSPOSE] button. * Pressing the C6 key produces normal keyboard pitch. Pressing the key to the left of C6 (B5) transposes the pitch of the keyboard down a semitone, the next key to the left (B b 5) transposes down a whole tone (two semitones), etc. , down to the F#5 key which transposes down 6 semitones. Upward transposition is accomplished in the same way using the keys to the right of C6, up to F #6 which transposes up 6 semitones. Note: The normal keyboard pitch is automatically selected when the power is turned ON. TOUCH SENSITIVITY The PDP-300 can be set to one of three different types of keyboard touch sensitivity -- HARD, MEDIUM or SOFT -- to match different playing styles and preferences. The HARD setting requires the keys to be played quite hard to produce maximum loudness. If the receiving device is a tone generator or another keyboard, it will respond in the same way as the PDP-300's internal tone generator when one of the pedals is used. The PDP-300 also receives and responds to the appropriate control change data. See "Control Change ON/OFF" on page 9 for information on turning control change number reception and transmission ON or OFF. MIDI Transmit & Receive Channel Selection The MIDI system allows transmission and reception of MIDI data on 16 different channels. Multiple channels have been implemented to allow selective control of certain instruments or devices connected in series. For example, a single MIDI sequencer could be used to "play" two different instruments or tone generators. One of the instruments or tone generators could be set to receive only on channel 1, while the other is set to receive on channel 2. In this situation the first instrument or tone generator will respond only to channel-1 information transmitted by the sequencer, while the second instrument or tone generator will respond only to channel-2 information. This allows the sequencer to "play" two completely different parts on the receiving instruments or tone generators. In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment must be matched for proper data transfer. An "OMNI" receive mode is also available, which allows reception on all 16 MIDI channels. In the OMNI mode it is not necessary to match the receive channel of the receiving device to the the transmit channel of the transmitting device (except when receiving mode messages). MIDI "Messages" Transmitted & Received by the PDP-300 The MIDI information (messages) transmitted and received by the PDP-300 is as follows: Note and Velocity Data This information tells the receiving keyboard or tone generator to play a certain note (specified by the MIDI note number) at a certain dynamic level (specified by the MIDI velocity value). [. . . ] If you should move, or if any doubt exists about the supply voltage in your area, please contact your dealer for supply voltage verification and (if applicable) instructions. The required supply voltage is printed on the name plate. For name plate location, please refer to the graphic found in the Special Message Section of this manual. 2. This product should be used only with the components supplied or; a cart, rack, or stand that is recommended by the manufacturer. If a cart, rack, or stand is used, please observe all safety markings and instructions that accompany the accessory product. 9. The power supply cord (plug) should be disconnected from the outlet when electronic products are to be left unused for extended periods of time. [. . . ]
