RM1x A. HOW TO ENTER THE TEST PROGRAM While pressing the [PATTERN], [PATT CHAIN] and [UTIL] buttons, turn the power switch on. The following message will appear on the LCD. When the [+1] switch is pressed, the test is automatically executed from the test where the error occurs. The [F4] switch is pressed, the “C-25 EXIT” is started. Manual Mode **RM1x TEST** MAIN Ver #.## SUB Ver #.## When the manual mode test is enterd, the following display will appear: **RM1x TEST**MANUAL MAIN Ver #.## SUB Ver #.
RM1x Test End After displaying the test result and the test will be finished. All the RAM data will be restored. Press the [F4] switch to exit the test, press the [+1] switch to proceed with the next test and then the [ENTER] switch to execute the next test. C-3 LCD ALL ON / OFF TEST 03: LCD Check Confirm that all LCD dots blink. Each line should blink in one (1) second intervals. Confirm that the LCD dots light normally. Confirm that the LCD contrast changes when rotating the contrast adjustment volume.
RM1x When it is normal, a piano tone is generated while being press on the switch. NG is displayed when another switch is pressed and a piano tone does not generate. After this, the test advances to the next switch test when a correct switch is pressed. C-5 PANEL SWITCH TEST 05: Panel Switch Press the panel switches consecutively from the [F1] switch to the [ENTER] switch, according to the order indicated by the LCD. Confirm all switches are working properly. Confirm the 32 channel sounds generate.

RM1x MIDI DATA FORMAT The RM1x tone generator and sequencer blocks handle different MIDIevents. These are listed seqparately in the MIDI Data Format as well as in the MIDI Implementation Chart.
RM1x SOUND CONTROLLER 6 adjusts the envelope decay time specified by the Voice. This is a relative parameter, and specifies an increase or decrease centered at 64. BRIGHTNESS adjusts the cutoff frequency specified by the Voice. This is a relative parameter, and specifies an increase or decrease centered at 64. Decreasing the value will make the sound more mellow. For some voices, the effective range may be less than the range of the setting.
