Thanks for your message.
Apple’s inter-app audio standard allows to assign one instance of a compatible app (instrument or effect).
Since this is a given limitation by Apple we can’t do anything against it.
As a workflow suggestion:
- Make sure “Unfreeze Deletes Audio Track” is not enabled in Setup/Arranger
- Create a master audio track to make your guitar recordings with BIAS FX
Once you have recorded a final guitar track:
- Tap the freeze button to mixdown the track with your desired BIAS FX setting
- Tap unfreeze, move the recorded (dry) track to a new audio track (as a backup)
Please note that Cubasis also supports Apple’s Audio Unit format that allows to use multiple instances of compatible apps. Once BIAS FX decides to supports AU, there will be no more limitations in using multiple BIAS FX instances.
Hope that helps.
