When the Input Strip Mode is set to Input the delay setting affects the only the delay on the strip’s signal. When{any Bus name} Return is selected as the Input Strip Mode the delay setting affects the delay on all other outputbus signals to ensure correct time-alignment.Delay Compensation of External InputsWhere an Output Bus or Aux Send Bus is used to feed an external processor via a physical output and the externalprocessor output is fed back into Pyramix via an external live input, then the necessary delay compensation mustbe computed and applied by the operator since Pyramix has no means of determining the delay of the externaldevice. However, the Input Strip Mode (Click on Input to pop-up the menu) should be set to the bus feeding theexternal processor (as above) so that the input channel delay setting affects delay compensation rather than simplydelaying the signal through the input strip.In the illustration, Aux Send Bus Ext Rev feeds an external device via physical outputs 17 & 18. The outputs of theexternal device are connected to physical inputs 7 & 8. The channels’ Mode has been set to Ext. FX Return anddelay compensation of 256 samples applied.In contrast Int FX output bus feeds Internal Return Buses 1 & 2 (IB1 & IB2). Two channels are fed by the IB1 &IB2 outputs with their mode set to Int FX Return.External Insert Plug-insInternal VS3 Engine latency is automatically compensated except for the daughter card I/O latency (for example aSend/Return on AES/EBU takes 6 samples). Thus you have to manually set the delay of the external unit plus the I/O latency. It is not possible to change the delay or change the bypass status during playback or recording.Determining Delay Compensation for External Effects LoopsOne strategy for achieving this is to route a signal directly to an output bus and, via an Aux Send, to a physical output,to the external processor’s input. The processors output is connected to a physical Pyramix input and routedto an input strip. The strip mode must be set to the bus used as the source. Then use impulse sounds, clicks, rimshotsetc. to aid manual adjustment of the delay compensation.Determining Delay Compensation for External Insert Plug-insA similar strategy can be employed here. Route the signal you wish to treat via an External Insert Plug-in to twoinput strips. Add the External Insert in one strip only complete with the external processor in circuit. Delay theuntreated strip until the audio is in sync with the treated audio and note the delay value. Then apply this value inthe Ext. Unit Delay field in the External Insert window.Effects Delay IndicationWhen the mouse cursor is hovered over a plug-in in a strip the required delay value is displayed:Input Type pop-upPlug-in Name and Delay pop-upHere you can see that Angudion II currently requires a 448 sample delay to be applied to the other output buses.This will be applied automatically when Full Delay Compensation is switched on.Mixer : Mixer Delay Compensation 10 - 180
