MainStage Loopback Sync, Snap To, and Play From
parameters
The Sync, Snap To, and Play From pop-up menus in the bar at the bottom of the window
control various aspects of playback and synchronization of the audio material.
Sync, Snap To, and Play From parameters
• Sync pop-up menu:Enables or disables synchronization with the MainStage tempo
and clock.
• Snap To pop-up menu:Determines how Loopback starts, in play or record mode, when
stopped. It also quantizes the tape loop length “on the fly” by stopping the first take.
• Off: Loopback starts immediately, without waiting.
• Beat: Loopback starts or stops at the start of the next beat.
• Bar: Loopback starts or stops at the start of the next bar.
• Loop: Loopback waits for the amount of time defined by the Length parameter.
• Play From pop-up menu:Determines the playback start position within the audio
material.
• Loop Start: Playback starts from the beginning of the audio material.
• Relative Position: When you stop and restart the Loopback instance, playback
continues as if the plug-in had been playing continuously, without interruption.
This is useful when several Loopback instances are playing together, or when you
are using Loopback instances with Playback or Ultrabeat instances, allowing you
to effectively “mute” and “unmute” instances while keeping them in sync with
each other.
Use the MainStage Loopback group functions
If you have multiple instances of the Loopback plug-in in a concert, you can use groups
to control which instances record and play together and which instances operate
independently. Any Loopback instance can either be assigned to one of 26groups, named
A-Z, or not be a member of any group. The linked operation of multiple instances can be
used for creative purposes, such as alternative versions of a song verse or chorus.
Loopback and Playback instances share the same group functions. If you have instances of
Playback that you have assigned to a group, they respond to any group functions (except
Record) as any Loopback instances assigned to the same group.
Only one group can be active at a time. For example, if two Loopback instances are in
GroupA, and four Loopback instances are in GroupB, activation of a transport function in
any GroupA member stops all GroupB members, and vice versa. Instances that are not
in any group are not affected. Similarly, any Playback instance in Group A also responds,
while Playback instances in Group B (or any other group) stop.
