Congratulations! ...and thank you for purchasing the Yamaha P-150. The P-150 is a high-performance electronic piano with full-scale, weighted action keyboard, a selection of high quality piano and other useful instrument voices, and versatile performance and other advanced features which make it ideal for professional stage and studio applications, as well as for home entertainment and music study use. The P150's main features include: s Dual and Split voice modes The P-150's Dual and Split modes let you play two voices at once, a "main" voice and a "sub" voice, either by layering the two voices of your choice (Dual mode) or by assigning a different voice to each end of the keyboard (Split mode). In Split mode, the key transposition values can be set independently for both main and sub voices. s One-touch Performance recall The P-150 features a Performance Play mode that lets you store up to 24 Performances, or configurations of all voice, MIDI and other parameter settings, for recall at the touch of a button. This lets you instantly change your sound and entire setup as you play, or between songs in a live set. The P-150 is set at the factory with 24 Preset Performances, but you can overwrite them and store User Performances which you create yourself. The P150 features extensive editing and storing capabilities. s High quality AWM piano and other sounds The P-150 features a selection of twelve high quality instrument voices generated by Yamaha's patented AWM (Advanced Wave Memory) sound generation technology. There are several piano sounds--including a concert grand piano, with full-bodied bass tones and reverberating high notes, that accurately captures the natural characteristics of a real grand piano--plus various electric pianos, vibes, organ combinations, strings and electric and upright bass. With a maximum simultaneous "polyphonic" note output of 32 notes, the P-150 delivers uncompromising performance capabilities. s Master keyboard features The P-150 offers many of the control features standard in a MIDI master keyboard, including velocity sensitivity, pitch bend and modulation wheels, an assignable CS (continuous slider), program change send and receive capabilities, MIDI transpose and merge functions, and bulk dumping and multitimbral capabilities. Plus, the P-150 gives you the option of connecting a foot controller (FC) that can be assigned MIDI and other functions in the same manner as the CS. With its powerful MIDI capabilities, the P-150 can easily feature at the heart of an expanded MIDI system. s Organ combination editing The P-150 comes equipped with two preset organ voices, plus organ combination editing features which let you create your own organ sounds and store them in Performances for instant recall. The organ combination editing features give you precise control over flute footages as well as attack settings. How to Use this Manual This owner's manual is organized and designed to help you get set up and begin enjoying the P-150 as quickly as possible, as well as to easily locate and learn about any feature you need. The GETTING STARTED section briefly but thoroughly explains the proper procedure for setting up the instrument, listening to the onboard Demo songs, and exploring the basic voices. The VOICE PLAY MODE, PERFORMANCE PLAY MODE and EDIT MODE sections include explanations of each feature and step-bystep details about how to access and manipulate the many parameters. An APPENDIX provides Voice and Performance lists and other technical information, including descriptions of error messages and a troubleshooting guide, plus MIDI specifications and other MIDI related information. Finally, an alphabetical INDEX lets you quickly reference the page number of any feature you want to locate. s Digital signal processing The P-150 has a built-in digital signal processor that lets you apply stereo reverb, chorus, symphonic and tremolo effects to the voices, and lets you tailor the quality of the voices to suit your needs with an internal equalizer, as well as a three-band graphic equalizer on the upper panel. s Touch-sensitive keyboard with velocity scaling The P-150's full-range 88-key, weighted action piano keyboard incorporates Yamaha's unique Action Effect II keyboard technology, which gives it the genuine feel and response of a real piano keyboard. You can even adjust the keyboard's sensitivity level, or velocity scaling, to suit your playing style, for both internal tone generator and MIDI message transmission. Special Symbols Throughout this manual two special symbols are used to connote additional information. Indicates an important cautionary note for the feature being described. Indicates a supplementary explanation for the feature being described. 1 s Location Do not use the P-150 in locations where it will be exposed to direct sunlight, extreme temperatures, high humidity or excessive dust or vibration. s Extended Disuse Electrical storms can cause power surges which can damage the P-150's circuitry even if the power switch is turned off. Therefore, it is best to disconnect the P-150's power cord from the AC outlet when you will not be using it for an extended period of time. s Handling Avoid rough handling. Do not drop the P-150 or subject it to shock, as these can damage the instrument's internal circuitry. Also, do not apply excessive force to the controls or terminals. When moving the P-150, first unplug the AC power cord and all other cables to prevent damage to the cords and jacks. When removing plugs from terminals, always grip the plugs directly rather than pulling on the cord. s Service and Modification The P-150 contains no user serviceable parts, so never open the instrument's cabinet or tamper with the internal circuitry or mechanisms in any way. Doing so can result in electrical shock or damage to the P-150. Refer all servicing to qualified Yamaha service personnel. s Cleaning To clean the P-150, use a slightly moist cloth and a neutral cleanser. Do not use abrasive cleansers, waxes, solvents, or chemically treated cloths, as these may damage the cabinet's finish or dull the keys. s Backup Battery The P-150's internal settings are preserved by a lithium backup battery which has a life span of approximately five years. (The battery's life span may differ, depending on the time elapsed between your P-150's date of manufacture and the date you purchased it.) When the battery charge runs low, the "ERROR1 REPLACE BATTERY" error message will appear in the LCD screen. If this message appears, save any settings you may want to keep to an external data storage device (such as the Yamaha MDF2 Data Filer) using the bulk dump procedure, then contact a qualified Yamaha service center to have the battery replaced. Do not attempt to replace the backup battery yourself! s AC Power The power requirements of your P-150 has been set to match the main power supply voltage in your area. Make sure that your local AC mains voltage matches the voltage as specified on the name plate located on the rear panel of your P-150. If you plan to use your P-150 in an area with a different voltage, be sure to use an appropriate converter. If you have any doubts about voltage compatibility, please consult your local Yamaha dealer. s Electromagnetic Interference Avoid using your P-150 near televisions, radios or other devices which generate electromagnetic fields, as electromagnetic interference can cause the P-150 to malfunction, and may generate interference noise in the other devices as well. YAMAHA CANNOT BE HELD RESPONSIBLE FOR DAMAGE CAUSED BY IMPROPER HANDLING OR OPERATION OF THE P-150! The LCD screen displays as illustrated in this manual are for instructional purposes only, and may appear somewhat different from your P-150's. 2
