Hi there
Status quo / problem
Currently integration of Avantis with an L-Acoustics L-ISA System is not directly possible but requires a completely separate control (surface) setup on the side which works but also is somewhat cumbersome and does not deliver an ideal workflow.
It would be desirable to control the essential L-ISA per channel/object parameters directly from the console; these include at least the fundamental spatial object parameters such as pan spread, pan, width, distance, elevation, possibly aux send (and likely some more) along with some interaction options like selection, linking etc.
Implementation Idea / Suggestion
Usability
Control of the per channel parameters could be done in a rather non-invasive manner such that the assign encoders provide access to all L-ISA parameters (very similar to the dynamics control) whereas it could also be handy to have the option to assign L-ISA parameters using the three custom rotaries on the side.
Likely a particular configuration view might also be required.
A more sophisticated per channel view of L-ISA parameters wouldn’t necessarily be required, for this external views of the L-ISA controller software could be relied on, which is more optimised for this purpose anyway.
Interfacing
The L-ISA controller provides several mechanisms for interfacing to external devices, such as OSC message or the more deeper Desklink integration.
I would think if integration is an aim, the desklink mechanisms would be most suitable.
Alternate approaches / Considerations
Aa a general, non-product specific solution having a series of channel-linked parameters that can be controlled directly through the surface and that interact with custom third-party solutions would provide an alternate means to achieve similar functionality at the cost of either introducing configuration complexity (setting labels, value ranges, etc) or being suboptimal (ie overly general) in terms of presentation.
For interfacing, MIDI could be used as an already existing component.
Related info
The L-ISA Controller software comes with some basic documentation also, at least covering the OSC interface whereas I would think that documentation pertaining to desklink integration is only available to manufacturers.
