Waves eMotion LV1 User Guide | Appendix E: Delay
APPENDIX F: DELAY GROUPS
eMotion LV1 can host plugins on every channel and buss. Different channels will likely use different plugins, each of which can impose
different delays. At each point where channels or busses are summed, they must be aligned with each other as a group. Those with
the least delay are aligned with those with the greatest. Summing to a buss does not add delay but adding plugins on the buss may.
When these busses are again summed, delay adjustment may again be needed. This is latency compensation.
The output to the Main L/R will have a certain delay (compared to the input) because of A>D converters, network buffers, and the
latency compensation introduced by plugins latencies throughout the Main L/R mix. But busses routed to different I/Os do not
necessarily need to be aligned with all other busses. Their delay alignment can be controlled as separate groups. These are Delay
groups.
To create multiple delay groups, the mixer must be set to Delay Groups. This is done in the Mixer Settings page (Settings > Mixer
Settings > Delay Compensation). Delay groups are assigned in the External Assignments section of the Channel window or in the
Patch window. Refer to the Setup chapter of this manual.
Set Mixer Delay Behavior
When using the mixer to produce latency critical outputs, for a monitor mix, for example, it is advisable to use Delay Groups mode.
This provides per-mix-buss output compensation, so that high latency busses will not affect low latency ones.
The Output Delay Behavior Box determines how delay compensation will be managed.
1. Entire Mixer: Total delay is the same throughout the mixer. All I/Os are aligned to the buss with the greatest delay. The user cannot
create separate delay groups in this mode.
2. Multiple Delay Groups: Enables I/Os to be assigned to separate delay groups. The I/Os that make up a delay group will be aligned
and delayed together.
