Controls in WRITE ENABLE can change to WRITE RECORD using any of the
following three methods:
1. Local Touch (Touching the control on the Channel Strip), CGM Touch
(or, for D950 only: CAS Touch). TOUCH RECORD engaged or the AUTO
MODE modifier key must be used.
2. (for D950 only) Local punch-in using the Channel Strip STAT (record
punch) key or the appropriate CAS controls.
3. Global punch-in via GLOBAL RECORD PUNCH IN key or Auto-Punch or
GPI (see
TRIM is the update mode of the system. Controls in TRIM ENABLE are
armed for recording offsets and allows Trims to be Auditioned. Those in
TRIM RECORD will apply the offset to previously written mix data and the
resultant values will be written to a new Mix Pass.
TRIM is handled slightly different for faders than for other automation ob-
jects. In both cases, Trim offsets are applied to the Read Mix Data for the
Active Pass, and a new Mix Pass is generated. The Read Mix data in the
new pass contain the values of the previous Active Pass plus the Trim off-
set. In addition, for faders, the Trim offset values are stored separately as
Trim Replay Data.
For faders not only is the Trim offset applied to Read Mix data to generate
a new Mix Pass, but the offset is stored within the new pass as Trim Re-
play Data. Trim Replay Data are absolute values that are used to offset
fader Read Mix values. Since the Trim Replay Data is separate from the
Read Mix Data, it may be manipulated as an independent entity. This
means that Trim Replay Data can be rewritten, modified, disabled from re-
play, and cleared.
Notes: Since the trimmed fader values are merged with the Read Mix data in the
new Mix Pass, the new pass has integrity even if the Trim Replay Data is
disabled or cleared.
While mixes created on earlier versions of D950 software are compatible
with AutoTouch+, mixes made on V2.5 or earlier versions do not contain
Trim Replay Data. However, Trims made with older versions are incorpo-
rated into Read data at the end of each Trim Pass. An older mix may be
played back using AutoTouch+ and Trim Replay Data may be added.
Mixes created using V3.0 software can be played back on systems using
earlier D950 software versions. The net results of all Trims will be heard
and the mix will playback perfectly. However, in V2.5 and earlier soft-
ware, the Trim Replay Data will be ignored and is not displayed by the
fader.
When a control is being trimmed, a Null indication is provided. In basic
terms, the null indication provides information regarding of the Trim offset
value. However, null indications are handled differently for faders than for
other controls.
Faders: The first time a fader is placed in TRIM, the null point is 0 dB and the
fader will snap to this position. It should be noted that the fader is showing
the null value rather than the Read Mix values and in this case it is 0 dB.
As the pass is played, the changes in the Read Mix values will be heard
