Disclaimer: I don't have either the A-49 or INTEGRA-7, and am just going by my interpretation of what's in the manuals.
By the way, if all you have is the printed manual then I would recommend that you
go to Roland's website and download the PDF version, because it's much easier to find information in a manual when you can search the PDF version for a specific word or phrase.
The SuperNATURAL button is just a toggle that's either on/lit or off/unlit. It's used in conjunction with the FUNCTION button to select one of four different operating modes:
- FUNCTION off/unlit, SuperNATURAL off/unlit = PLAY mode -- for playing the keyboard with a generic sound module.
- FUNCTION on/lit, SuperNATURAL off/unlit = FUNCTION mode -- for setting the values of the controller's various functions.
- FUNCTION off/unlit, SuperNATURAL on/lit = SuperNATURAL mode -- for playing the keyboard with a SuperNATURAL sound module (e.g., the INTEGRA-7).
- FUNCTION on/lit, SuperNATURAL on/lit = MIDI Visual Control mode -- for playing the keyboard and controlling a video device that supports MVC (MIDI Visual Control).
Unless you have a video device that supports MVC, you should just ignore and avoid the MIDI Visual Control mode, since it would be pointless to use it.
However, you do have a SuperNATURAL sound module, so I assume that the SuperNATURAL mode is the one you'll be most interested in. Since the A-49 can't generate its own sounds, the SuperNATURAL mode simply "preconfigures" the A-49 to control specific functions in a SuperNATURAL sound module, as shown in the chart on page 24:
- PITCH button = Same as in PLAY mode -- i.e., when on, the D-BEAM controls the pitch for notes you play.
- VOL button = Same as in PLAY mode -- i.e., when on, the D-BEAM controls the volume for notes you play.
- ASSIGN button = CC#18 (which varies with the SuperNATURAL voice) -- e.g., Mute, Growl Sens, Slide Roll, etc.
- FUNCTION button = (Not used in SuperNATURAL mode.)
- S1 button = CC#80 (which varies with the SuperNATURAL voice) -- e.g., Dead Stroke, Mute, Rasgueado, Finger Picking, Staccato, Slap, etc.
- S2 button = CC#81 (which varies with the SuperNATURAL voice) -- e.g., Harmonics, Octave Tone, Pizzicato, etc.
- C1 knob = CC#16 (which varies with the SuperNATURAL voice) -- e.g., Noise Level, Mallet Hardness, Resonance Level, etc.
- C2 knob = CC#17 or CC#19 (which vary with the SuperNATURAL voice) -- e.g., Roll Speed/Bend Mode, Strum Speed/Strum Mode, Glissando Mode, etc.
- Pitch Bend/Modulation lever = Same as in PLAY mode -- i.e., controls the pitch and vibrato for notes you play.
- TRANSPOSE button = Same as in PLAY mode -- i.e., controls the amount of transposition for notes you play.
- +/- buttons = Same as in PLAY mode -- i.e., controls the octave number for notes you play.
- HOLD jack = Same as in PLAY mode -- i.e., lets you connect a hold/sustain pedal so you can hold/sustain notes you play.
- EXPRESSION jack = Same as in PLAY mode -- i.e., lets you connect an expression pedal so you can control various parameters and functions.
As you can see, SuperNATURAL mode affects only six of the A-49's controls, and the five which are actually used will have different functions depending on which voice has been selected in the SuperNATURAL sound module-- see pages 100 - 108 in the INTEGRA-7's Parameter Guide.
As long as you don't have the SuperNATURAL button on, the FUNCTION button is used to switch between PLAY mode and FUNCTION mode. FUNCTION mode lets you set the values for various functions.
I think you'll want to check out the FUNCTION mode, too-- which I didn't go into yet-- because it looks like FUNCTION mode is what you use to select which voices you want the A-49 to play on the INTEGRA-7. I think the main trick is knowing that the FUNCTION and SuperNATURAL buttons work together to select between those four operating modes.
