[. . . ] 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. 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. We sincerely believe that our products and the production methods used to produce them, meet these goals. [. . . ] If you want to keep your recorded data for longer periods, turn the power on briefly at least once a week. It is also possible to store it to an external MIDI storage device such as the Yamaha DOU-10 Disk Orchestra Unit by using the Bulk Dump function described on page 20. · The track indicators will not light automatically when the power is turned on even if the recorder contains data. It is therefore necessary to press the track buttons so that the corresponding green indicators light before starting RECORDER playback. It is also a good idea to press the track buttons to check if the tracks contain data before recording. If the green indicator lights when the corresponding track button is pressed, that track contains data which will be erased and replaced by the newly-recorded data. · If the metronome is being used during playback, the metronome will stop when playback is stopped. · The playback data is not transmitted via the MIDI OUT connector. q Fast Forward Playback RECORDER 1 2 When you want to locate a specific point in a recording you can quickly move forward through the recording while monitoring the sound by pressing the [REC] button while holding the [MIDI/TRANSPOSE] button. MIDI/ TRANSPOSE PLAY REC 14 MIDI Functions q A Brief Introduction to MIDI MIDI Cable MIDI OUT MIDI IN DOU-10 Clavinova 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 (including the Clavinova, of course) 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 (essentially a synthesizer with no keyboard), 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 multiinstrument sounds. This same type of musical information transfer is used for MIDI sequence recording. A sequence recorder can be used to "record" MIDI data received from a Clavinova, for example. When the recorded data is played back, the Clavinova automatically "plays" the recorded performance in precise detail. The CLP-154S/155 offers a number of MIDI functions that allows it to be used in fairly sophisticated MIDI systems. NOTE Data Being Recorded Playback Data MIDI OUT MIDI IN MIDI OUT MIDI IN DOU-10 Clavinova · Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI cables longer than about 15 feet, since cables longer than this can pick up noise which can cause data errors. q MIDI "Messages" Transmitted & Received by the Clavinova The MIDI information (messages) transmitted and received by the Clavinova are 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). Note and velocity data is transmitted by the Clavinova whenever a key is pressed, and the Clavinova's internal AWM tone generator will "play" the corresponding note(s) whenever note and velocity data is received from an external MIDI device. Program Change Numbers The CLP-154S transmits a MIDI program change number between 0 and 5, and the CLP-155 transmits a MIDI program change number between 0 and 7 when one of its voice selectors is pressed. This normally causes the correspondingly numbered voice to be selected on a receiving MIDI device. The Clavinova will respond in the same way, automatically selecting the appropriate voice when a MIDI program change number is received. See "Program Change ON/OFF" on page 17 for information on turning program change number reception and transmission ON or OFF. [. . . ] This equipment generates/uses radio frequencies and, if not installed and used according to the instructions found in the users manual, may cause interference harmful to the operation of other electronic devices. Compliance * This applies only to products distributed by YAMAHA CORPORATION OF AMERICA. with FCC regulations does not guarantee that interference will not occur in all installations. If this product is found to be the source of interference, which can be determined by turning the unit "OFF" and "ON", please try to eliminate the problem by using one of the following measures: Relocate either this product or the device that is being affected by the interference. Utilize power outlets that are on different branch (circuit breaker or fuse) circuits or install AC line filter/s. [. . . ]
