Clavia DMI
Performs tests 3,12,4,6 and 7.
Only used in production.
Tests the EEPROM.
Tests the five DSP´s, including external memory and
communication between DSP´s.
Tests the two D/A converters. Output a sine wave on the 4 outputs
CH1 Out
220Hz
Toggle between outputs with [ Page+ ] or [ Page- ]
Outputs a 1KHz sine -100dB or noise -70dB on the 4 outputs.
Toggle between sine or noise with [ Page+ ] or [ Page- ]
Shows the USB chip ID. This test can not detect if the USB
communication with a computer is functional. To test USB
communication, simply connect the Stage to a computer running
the Stage manager.
Test MIDI communication.
Connect a cable from MIDI in to MIDI out
Press one key at a time. The test shows which key is pressed and

Performs tests 4,6,10 on panel 2.
Tests first the LED´s followed by a button test.
Step to next section with [ Page+ ].
Tests the LCD panel.
Tests all of the encoders. Requires that each encoder is turned
two turns.
Shows the Pitch stick calibration range. (36-40)
Shows the Pitch stick base value. (52-74)
Tests the pitch stick function. Left = 0 Right = 64
Tests the function of the A/D converter on the panelboard
