Sysex message transmission

Using Arduino Audio
#1

Hello guys. I wonder if it is possible to program an Arduino (as a stand alone device) in order to send single a Sysex message using a switch to a MIDI device?

I need to send these two Sysex messages to a Roland JV-1010 in order to switch the Scale tuning ON and OFF.

Scale tune ON= F0 41 10 6A 12 00 00 00 07 01 78 F7

Scale tune OFF= F0 41 10 6A 12 00 00 00 07 00 79 F7

I have programmed the scale tuning values in JV-1010 module and now, I like to be able to turn it on and off without the computer.

Any help is highly appreciated. Ciao!

Yes it is.

Scale tune ON= F0 41 10 6A 12 00 00 00 07 01 78 F7

Scale tune OFF= F0 41 10 6A 12 00 00 00 07 00 79 F7

Just send those bytes out to the MIDI device.

Thank you Mike. Do you think this code is correct?

#include

//Scale tuning switch for Roland Jv-1010

int switchPinON = 8;
int switchPinOFF = 7;
byte onArray[12] = {0xf0, 0x41, 0x10, 0x6a, 0x12, 0x00, 0x00, 0x00, 0x07, 0x01, 0x78, 0xf7}; // ON array
byte offArray[12] = {0xf0, 0x41, 0x10, 0x6a, 0x12, 0x00, 0x00, 0x00, 0x07, 0x00, 0x79, 0xf7}; // OFF array

void setup() 
{
pinMode (switchPinON, INPUT);
pinMode (switchPinOFF, INPUT);

}

void loop()
{

if (digitalRead(switchPinON) == HIGH)
{
sendSysex (10, onArray, true);
}
}
if (digitalRead(switchPinOFF) == HIGH)
{
sendSysex (10, offArray, true);
}
}

I am a completely noob to Arduino; So this is all I could figure out! Arduino is showing error on this code Indeed! Would you guys please help me out with this? Thank you!
