The Function Mode F6 CLP-411 MIDI Functions F8 CLP-511 MIDI Functions q A Brief Introduction to MIDI MIDI, the Musical Instrument Digital Interface, is a world- MIDI Cable standard communication interface that allows MIDI-compatible MIDI OUT MIDI IN musical instruments and equipment to share musical information and DOU-10 control one another. This makes it possible to create "systems" of MIDI instruments and equipment that offer far greater versatility and Clavinova 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 multi-instrument sounds. This same type of musical information transfer is used for MIDI Data Being Recorded sequence recording. A sequence recorder can be used to "record" Playback Data MIDI data received from a Clavinova, for example. When the MIDI OUT MIDI IN MIDI OUT MIDI IN recorded data is played back, the Clavinova automatically "plays" DOU-10 the recorded performance in precise detail. The examples given above really only scratch the surface. MIDI can do much, much more. The CLP-411/511 MIDI functions allow it Clavinova to be used in fairly sophisticated MIDI systems. After selecting "F6Y. " or "F8Y. ", press the [+/YES] button to engage the MIDI function submode, then use the [] buttons to select the desired MIDI function, as listed below. NOTE • The rear-panel HOST SELECT switch must be set to "MIDI" in order to use the MIDI connectors. • 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. F6.1/F8.1: MIDI Transmit Channel Selection F6.2/F8.2: MIDI Receive Channel Selection The MIDI system allows transmission and reception of MIDI data on 16 differ- MIDI OUT DOU-10 MIDI IN MIDI THRU MIDI IN Tone Generator (Set to receive on MIDI channel 2) Clavinova (Set to receive on MIDI channel 1) ent channels. Multiple channels have been implemented to allow selective control of certain instruments or devices connected in series. For example, a single MIDI sequence recorder 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 sequence recorder, while the second instrument or tone generator will respond only to channel-2 information. This allows the sequence recorder to "play" two completely different parts on the receiving instruments or tone generators. 26
