[TIP] Panic combination: pressing the [RO-
TARY ENCODER] and
[BUTTON-DOWN]
simultane-
ously will turn off all playing notes and reset con-
trollers.

[INFO] MIDI events coming in on the MIDI in
port [MIDI IN SOCKET] can be automatically sent
out again on the MIDI out port [MIDI OUT SOCKET]
without any processing (MIDI THRU feature). See
section
[TIP] If you don’t seem to be getting MOTAS-
6 to play properly then use this MIDI diagnostics
page to check that indeed the correct MIDI events
are being received. If not then a common problem
could be that you have not set up your external
MIDI device correctly, or a cable is not connected,
or MOTAS-6 is set to the wrong MIDI receive chan-
nel.
If there is incoming MIDI clock data then the beats per min-
utes (BPM) of the clock is displayed at the bottom left of
the screen.
16.3 Oscilloscope
The oscilloscope mode allows you to ’see’ the output au-
dio waveform on the display. Time increases from left-to-
right horizontally. Using the [ROTARY ENCODER] the dis-
play time can be zoomed in or out. The horizontal scale is
divided into divisions with feint vertical dashed lines. The
current time scale is shown in the bottom right-hand side
of the display. For example, in the figure the setting is
2.5 ms (i.e. 2
1
2
thousandths of a second) per division.
Press [2] to pause/unpause the display (pause shown by
P on the screen). Press [1] to auto-scale the vertical dis-
play (shown by an R on the screen). Note that the rescal-
ing is limited and so for weak signals rescaling may not
cause the waveform to fully fit the display. Press
[BUTTON-
UP]
and
[BUTTON-DOWN]
to manually set the vertical display
scale (from x1 to x16 zoom).
i
[INFO] The signals are measured on the au-
dio output directly before the main volume con-
trol, so waveforms can still be seen even if the vol-
ume level is at the minimum setting.
[TIP] Use the oscilloscope feature with
’page-lock’ enabled whilst adjusting parameter
controllers for e.g. filter cut-off or resonance to
see the effect on the waveform!
[ADVANCED-INFO] Internally the oscillo-
scope feature works by digital sampling of the au-
dio signal. The timebase is synchronised to the
waveform as far as possible in order to prevent a
’rolling’ display, however, depending on the wave-
form shape good synchronisation may not be pos-
sible.
16.4 Spectrum analyser
In spectrum analyser mode the amplitude (or volume level)
of the audio signal versus frequency (or pitch) is shown.
The horizontal scale is divided into divisions with feint ver-
tical dashed lines. The current frequency scale is shown in
the bottom left-hand side of the display. For example, in
the figure the setting is 100 Hz per division.
