QUESTION:
Do we have to have Crystal XI to use it?  Will Crystal 10 work?

ANSWER:
The RDC interface has been a relatively stable API for the past few revisions of Crystal, so our class may well "work" with older revisions. However, it's important to understand that we used Crystal XI to generate the classes (so it has all the latest features, which may be new or different from older revisions) and we specifically support Crystal XI.

Just like any ActiveX components, developers can always choose to import the classes from the specific revision of Crystal and use them instead of ours. The main difference is that you would have the DAW supported classes, docs and examples as a model to work from (we would still be specifically supporting ours).

As with all environments, the further away from the main revision you get, the more likely there will be issues due to incompatibilities (i.e. Crystal 10 has a better chance of working well for you than revisions that are even older).
