Undo & Redo; Nulling - (Faders & Pan Controls) - Roland VXpanded VS-880 Application Manual

Using Waveforms To Edit
The VS-880 Scrub feature makes it very easy to find your edit points because you can see a visual
representation of the sound and hear it at its original pitch while editing at a fine resolution of down to
1/3000th of a second. (See Owner's Manual pages 76-77.)
Undo & Redo
The UNDO command will reverse your previous actions up to 999 times. Press the [UNDO] button and the
LCD will display - UNDO Level = 1. The TIME/VALUE dial will allow you to select how may previous
actions to reverse (undo). For example, if you make 5 recordings on the same track (see figure below) and
then execute the UNDO command with level 3, you will erase (undo) the past three actions (the past three
recordings). Recording # 2 will now be the one that plays back.
After completing an UNDO command, the UNDO LED will be lit. You can play your song to see if you are
happy with the UNDO. If you are not, hold the [SHIFT] button and press the [UNDO] button to REDO the
functions. This will effectively cancel the UNDO function you have just completed.
The UNDO command operates for ALL functions of the VS-880. This includes
recording, editing, etc. (see Owner's Manual pages 112-113 for more information)
Nulling - (Faders & Pan Controls)
Since the physical controls of the VS-880 provide multiple functions (depending on the mixer mode
setting), there must be some way to match the 'physical' control position to the 'electronic' control position
inside the mixer.
For example, let's assume that you set Fader # 1 to a physical front panel position of -8 dB while using
INPUT MIX mode. Since you set this Fader in real time, the internal 'electronic' level is -8 (the same as the
physical control). Then you switch mixer modes to TRACK MIX. Now you set Fader # 1 to a physical
position of +4 dB to mix Track # 1. When you switch back to INPUT MIX mode, the 'physical' fader is set
to +4 (you just set it there), but the internal 'electronic' level is still set to -8 dB (which you set the last time
you were using INPUT MIX mode).
In order to realign the physical and electronic levels, the VS-880 provides a function in the System
Parameters called Fader Match. When Fader Match is set to Null, the VS-880 will ignore any movements of
the physical fader, until the physical fader position and the internal electronic position are equal (Nulled).
In other words when you begin to move the fader from the +4 position, no change will occur in the audio
until you lower the fader to -8. Once the internal and physical levels match, the fader will continue to
operate normally. The Pan controls operate in the same manner.
When Fader Match is set to Jump, the actual value will change to the current position of the fader or pan
knob at the instant they are moved.
