3) Page Buttons
Within each mode, the available disk files, commands, and parameters are organized into Pages.
A page is selected by pressing one of these fourteen page buttons. Once you are on the correct
page, you use the Data Entry Controls to scroll through the files, commands or parameters on
the page. A given page will have different functions depending on the current mode. Each mode
has a different set of pages available. Not all fourteen page buttons are active in all three modes.
The ten numbered page buttons also double as a numeric keypad for “direct-dialing” a given disk
file, command, or parameter or for sending MIDI Program Changes.
4) Data Entry Controls
Once you are in the desired mode and have selected the proper page, you use the controls in the
data entry section to: locate and load the desired file (in Load mode); locate and execute the
desired command (in Command mode); or locate and modify the value of the desired parameter
(in Edit mode).
• The Data Entry Slider and the Up and Down Arrow buttons will: move through the files on
the current disk or directory (in flashing LOAD mode); change the value of the current
parameter (in Edit mode); or respond when the ASR-10 asks you for further input during the
execution of a command (in Command mode).
• The Left and Right Arrow buttons are used primarily to move to the next parameter or
command on the current page.
Tip:
To advance by screens (instead of by parameters), while holding down the Right Arrow button,
press the Up Arrow button, or while holding down the Left Arrow button, press the Down
Arrow button.
• The Enter•Yes and Cancel•No buttons are used to either proceed with or cancel the function
currently showing on the display.
Tip:
When editing any parameter, pressing Cancel•No will reset the parameter to the value it was set
to before it was last edited.
Tip:
In Load mode, successive presses of the Cancel•No button will alternate between solid and
flashing Load modes.
Tip:
When editing any parameter that has a center value, there is an easy way to reach that value.
While holding down the Down Arrow button, press the Up Arrow button, then quickly release
both buttons.
Parametric Programming
The method used to modify or edit programs, presets and system parameters is called Page-
driven Parametric Programming, which sounds like a mouthful, but don’t worry. Once you’ve
grasped a few basic concepts you’ll find that operating the ASR-10 is quite simple, given its many
capabilities.
It is likely that you have already encountered some form of parametric programming on other
synthesizers or samplers. What this means is that instead of having a separate knob or slider for
each function, you have one master Data Entry Slider and the Up/Down and Left/Right Arrow
buttons, which adjust the value of whichever parameter you select.
This approach has many advantages, the most obvious is that it greatly reduces the amount of
hardware — knobs, switches, faders, etc. needed to control a wide variety of functions. If the
ASR-10 had a separate control for each function, it would literally have hundreds of knobs.
