Alesis ALESIS M20 DIGITAL SCRUB: DIG SCAN: ON/OFF, NN dB, I/O C, SMPTE CHASE WITH THE STOP BUTTON, TAPE TC UPDATING WHEN IN INPUT MODE, VARI-SPEED AND PULL-UP/DOWN

M20 Software Version 2
M20 ADDENDUM 2.1 MA-5
DIGITAL SCRUB: “DIG SCAN: ON/OFF, NN dB”
A Digital Scan page has been added to the Utility pages. This allows the user to have
control over digital audio output when in jog/shuttle mode. The output may be attenuated
in 6 dB increments (0 dB to –42 dB).
Note the following when using Aux Track routing:
• Aux routing play back through the “AUX” selected channels is defeated when Digital
Scan mode is enabled.
• Cue and review scanning will always output audio at –6 dB regardless of the DigScan
status and the attenuation setting.
I/O CARD AS THE DIGITAL SOURCE
• The “D” indicators in the Meter Display are now always lit solid when the Digital
Source is I/O Card and the Clock Source is from a source other than I/O Card (even
when the selected clock source is not present).
• When the Digital Source is set for I/O Card, there are some limitations on the routing.
Basically, the AES/EBU and analog input share the routing, i.e., they are one in the
same. What this means is that when the Dig Source = I/O Card, only I/O Card routing
(1/2 à 3/4, 5/6, 7/8, 1-4 à 5-8, or 1-8 à 1-8) is allowed. The analog input routing will
not be editable and will follow (be the same as) the I/O Card routing. If control of
analog input routing is desired, the digital source cannot be I/O Card. Also, note that if
the user wants to mix the I/O Card and analog inputs, Input Routing mode must be set
to 1-to-1.
SMPTE CHASE WITH THE STOP BUTTON
If currently chasing SMPTE, pressing the Stop button will now stop the tape and disable
SMPTE Chase.
TAPE TC UPDATING WHEN IN INPUT MODE
When the TC Track is input enabled, the SMPTE Rate will not automatically change when
transitioning from an area of tape with no tape TC into tape TC.
VARI-SPEED AND PULL-UP/DOWN
When the M20 is set for a pull-up/down, changing the pitch mode to VARI (by pressing
Pitch Mode or by entering a non-zero vari-speed value) now disables the pull-up/down.
Likewise, when the M20 is in vari-speed, enabling pull-up/down returns the M20 to FIXED
pitch mode operation.
