User manual YAMAHA DX7S

[. . . ] YAMAHA DIGITAL PROGRAMMABLE ALGORITHM SYNTHESIZER OWNER'S MANUAL SUPPLEMENTAL MARKING INFORMATION Yamaha Digital Musical Instrument Products will have either a label similar to the graphic shown below or a molded/stamped facsimile of the graphic on its enclosure. The explanation of these graphics appears on this page. The Exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT REMOVE COVER (OR BACK). [. . . ] Both of the these buttons call up multiple LCD displays. The charts below show all of the displays called up by each button, and provide a complete list of parameters and value ranges. In some cases, the first LCD display in a chart may not be the first one you see. You may need to cycle through the displays (by pressing the button repeatedly) until you reach the desired LCD display. - 61 - Button 14 LCD Displays - 62 - - 63 - Memory Types The chart below is a graphic representation of the way all the different DX7s memory areas interact with one another. Since there are many facets to the memory layout of the DX7s, it may look intimidating at first. Once you become more familiar with the instrument, though, you will fjnd the memory layout is much simpler than it first appears. To understand all of the memory types, study the diagram and read the explanation below: Voice & Performance Memory This Memory block includes data for 64 Voice Memories and 32 Performance Memories, plus one System Setup Memory and two User-defined Micro Tunings. - 64 - System Setup Memory System Setup Memory contains most of the basic MIDI settings. System Setup is always retained in Internal Memory, along with the Voice & Performance Memory and the two User-defined Micro Tunings. For more information on System Setup Memory, see Section 6 of this manual. Micro Tuning Memory The DX7s contains eleven Micro Tunings as part of its permanent memory. In addition, two User-defined Micro Tunings are stored as part of Voice & Performance Memory. Using a RAM cartridge, it is also possible to store up to 63 Micro Tuning Memories. Fractional Scaling Memory Fractional Scaling data cannot be stored in the DX's Internal Memory. In order to use Fractional Scaling data with Internal Voice Memories, the data must reside in a RAM (or ROM) cartridge installed in the DX's cartridge port. Initialized Memory For those who wish to create Voice Memories or Performance Memories from scratch, the DX7s provides both Voice and Performance "blank page" data as part of its permanent memory. If you want to start from ground zero (instead of working from an alreadyexisting Voice or Performance Memory), call up the DX's Init Voice or Init Performance data (using button 14 in Edit Mode). Current Play/Edit Memory Whenever you call up a Voice Memory or Performance Memory in Play Mode, you are actually sending it to a special location in the DX7s -- the current Play/Edit Memory. As the name indicates, this is also the location where Voice or Performance data is edited. In computer terminology, this memory location is often called the Edit Buffer. Compare/Recall Memory When you are editing a Voice or Performance and use the Edit/Compare feature, the original Voice data is loaded into the Play/Edit Memory (so you can hear it). The edited Voice data is moved temporarily into another memory location, the Compare/Recall Memory. In computer terms, this memory location might be called the Compare Buffer. [. . . ] When not in use, always turn your Yamaha Digital Musical Instrument equipment "OFF". The power supply cord should be unplugged from the outlet when the equipment is to be left unused for a long period of time. NOTE: In this case, some units may lose some user programmed data. Factory programmed memories will not be affected. [. . . ]
