Varispeed
The Varispeed control mode is implemented in Version 3.0 software. This function allows
playback of audio over a range of speeds from 88.5% to 104.33% of nominal play speed. The
precise speed can be set in increments of .1% over the entire range. To use the Varispeed function,
go to Setup Menu 000 and choose Varispeed as the Control Mode.

*100% Bottom:(range 88.5% to 104.3%)
This function works by changing the sampling rate of the unit and this is reflected in the sample
rate of the digital audio output stream from the MMR/MMP, which will vary according to the
speed set in this menu. This is different from the jog/shuttle mode because that mode produces a
constant sample rate output while scrubbing audio off speed. Note that the Varispeed Mode is
mutually exclusive with Time Code Chase or Biphase Chase and thus the unit cannot be
synchronized to an external source while in this mode. To instantly return to the default of 100%
(nominal speed), go to Setup Menu 006, press Trim, then press SHIFT + CLR.
Audio File Time Stamp Support
Version 3.0 adds a time code “stamp” as an attribute of all recorded files. This time code stamp
represents the time code location of the MMR unit when the recording was made. This data is now
recorded as part of the audio file data. This information will be retained when files are Backed Up,
Converted, or Exported to a different format. Many Digital Audio Workstations can use this
information to place audio at its recorded time code location for editing.
New SCSI Driver
The software code which controls the operation of the MMR/MMP SCSI disk interface, known in
engineering parlance as the “SCSI Driver” has been completely re-written for Version 3.0. This
has been done to allow more precise control of certain SCSI disk operations and to improve system
performance when dealing with very densely edited material. Changes to MMR/MMP operation
caused by this new SCSI Driver are outlined below.
No need to restart after low format
In previous software versions, performing a Low Format (Setup Menu 711) would require a
system reboot before the drive could be initialized or another drive used. In Version 3.0, the Low
Format process does not interfere with normal operation after the volume has been formatted.
