Multi-channel signals. Modify Trace shape or create a new shape?

[apdavison]

A request for feedback:

I need to represent multi-channel electrophysiology data. This could be done either by modifying the existing Trace shape or by creating a new shape for multi-channel data, leaving Trace specific for single-channel data.

Any thoughts on the best approach?

Thanks for your question, @apdavison ! My feeling is that it would be most appropriate to use the Trace shape to describe shared property shapes between all traces and hence to create more specialised shapes for multi-channel electrophysiology data as well as single-unit electrophysiology recordings. Maybe you could come up with a proposal for the multi-channel trace shape? We could take care of the refactoring of the existing Trace shape to remove the property shapes which are specific to the single-unit recording use case. What do you think, @MFSY ?
