HDR 24/96
Transport Operation
The transport controls and time code display are two of the most important functions on the HDR. This is
the part that looks and works most like a tape recorder. In this section, we’ll describe the basic transport
controls as well as position location, monitoring, and metering
Transport operation can be controlled from the front panel, the GUI, or remote controller. Click on the
GUI button or press the hardware button, whichever is more convenient. Most transport controls also
have keyboard shortcuts.
The transport can also be configured to follow MIDI machine control (MMC) commands from an
external device such as a mixing console or a sequencer, and to synchronize to incoming SMPTE or MIDI
time code (MTC). Refer to Sync and MIDI reference sections for appropriate setup and operational
information.
The Virtual Play Head
The HDR can be called a "non-linear" or "random access" recorder. This is because the HDR stores
audio data on a disk drive and not on a continuous linear piece of media like tape. Any data on the
disk can be accessed instantly by the HDR operating system regardless of its physical location or
arrangement on the disk. This feature is known as random access. This does not mean the data is
randomly placed on disk; what it really means is that you don't care where it is on disk, and further
you can "randomly" select where in your time line you want to be recording and/or playing back.
Because access is instantaneous, there is never any rewind or fast forward time (unless you want
that!).
While recordings on the HDR are not necessarily organized as continuous pieces of data on the disk,
the HDR does organize the data for you in a head-to-tail linear form within the user interface. In the
HDR GUI, time flows from left (earlier) to right (later). Audio representations on tracks start on the
left where for example, the intro leads into the verse, which is followed by the chorus, and so forth
moving to the right. Every moment of audio recorded into your HDR bears a relationship to time,
and will initially show up on a track in the GUI display. The point in time where the HDR is now
playing or recording data is known as the Current Time (and in some cases - the Play Head Position,
Tape Time, or the Now Line). In essence the HDR is providing a "virtual" play head, which it
represents in the GUI as a vertical line across the Track area. As time progress from earlier to later,
the virtual play head moves to the right across the "virtual tape" (representations of audio on tracks)
beneath it.
NOTE: If the Auto Scroll feature is on, the virtual play head remains stationary in the center of the
Track Area and the virtual tape (audio representations) scroll to the left underneath the vertical line.
Basic Transport Controls
The basic transport controls both look and operate
the same on the HDR24/96 front panel, the
Remote 24, and the Remote 48.
