By creating (and storing) the special scales required by these types of music, you can instantly select the tuning you need — even lohile playing! The ASC-10 Concept The vast majority of Western music forms — and instruments — are based on the twelve tone tuning system often referred to as Equal Temperament. In this tuning system, one octave is divided into twelve tones with adjacent tones being a semi-tope apart in pitch. This 'equal spacing' of tones is the basis for the name Equal Temperament (equal tuning). Although this tuning system is used extensively, there are many forms of music in the world which use different tunings. Some types of music use semi-tones and quarter-tones within the same scale (Arabic music, for example). Still other types of music use micro-tones; intervals smaller than a quarter-tone. By allowing you to raise or lower the pitch of individual notes within the equally tempered scale, the ASC-10 can create whatever tuning system your music requires.

IMPORTANT NOTES Power Supply • Use only a BOSS PSA AC Adoptor (sold separatelty). • When making any connections with other devices, always turn off the power to all equipment first; this will help prevent damage or malfunction. • Do not use this device on the same power circuit with any device that will generate line noise, such as a motor or variable lighting system. • The power supply required by this unit is shown on its nameplate (rear panel). Be sure the line voltage in you installation meets this requirement. • Avoid damaging the power cord; do not step on it, place heavy objects on it, etc. • When disconnectingthe AC adaptor from the wall outlet, grasp the plug itself; never pull on the cord. • If the unit is to remain unused for an extended period of time, unplug the power cord from the wall outlet. Placement • Do not subject the unit to temperature extremes (eg., direct sunlight in an enclosed vehicle). Avoid using or storing the unit in dusty or humid areas. • This device may interfere with radio and television reception. Do not use the device in -the vicinity of such receivers. Maintenance • For everyday cleaning wipe the unit with a soft, dry cloth (or one that has been slightly dampened with water). For stubborn dirt, use a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit with a soft, dry cloth. •Never use benzene, thinners, alcohol or solvents of any kind, to avoid the risk of discoloration and/or deformation. Additional Precautions • Protect the unit from strong impact. • Do not allow objects or liquids of any kind to penetrate the unit. In the event of such an occurrence, discontinue use immediately. Contact qualified service personnel as soon as possible. • Should a malfunction occur, or if you suspect there is a problem, discontinue use immediately. Contact qualified service personnel as soon as possible. • To prevent the risk of electric shock, never attempt to open the unit or the AC adaptor. Memory Backup • This unit contains a battery which maintains the contents of memory while the main power is off. The expected life of this battery is 5 years or more. However, to avoid the unexpected loss of memory data, it is strongly recommended that you change the battery every 5 years. Please be aware that the actual life of the battery will ■depend on the physical environment (especially temperature) in which the unit is used. When it is time to change the battery, consult with qualified service personnel. ROLAND ASC-1D Front Panel : I I CANCEL WRITE MIDI MODE 8 —r| MIDI 1 Panel Description O [USER MEMORY] Buttons Each of these buttons ([1] — [8]) corresponds to a memory position where you'll store your custom-tuned scales. Once a scale (tuning) has been stored, pressing the corresponding button will instantly implement that scale. These buttons are also.used in selecting the Part(s)/MIDI channel. © Number (MIDI) Buttons These buttons ([1 ] — [16]) are used when selecting Parts in the GS mode, or the MIDI channel in the Bender mode. © Note Buttons These twelve buttons correspond to the twelve tones of an equally tempered scale: C — B. To create a custom scale, simply select the note(s) you wish to change by pressing the corresponding button(s). Then raise or lower the pitch of the note(s) you have selected. Buttons [9] — (16] are also used in selecting the Part(s) / MIDI channel. © [CANCEL] Button This button cancels the custom tuning (scale) currently in effect; the tuning instantly returns to equal temperament. If you press and hold a Note button (whose assigned pitch has been detuned) and then press [CANCEL], that note will be returned to standard pitch. © [WRITE] Button This button (in conjunction with the [USER MEMORY] buttons) is used to store the custom scales you create. © [MIDI] Button...
