I have easy drummer, three and superior drummer III as well. I am a recent convert from logic Pro. In logic, you can use the virtual Drummer in conjunction with arrangement markers so that the virtual Drummer will fill in parts commensurate with the part of the song in the arrangement. I’m looking at possibly buying the full version of groove agent but the thing that would throw me over the edge about it is if there was some integration with Cubase 14 similar to that logic pro. In other words, what would make it better for me than easy Drummer is the integration with Cubase hopefully with the arrangement track. Do any of you know of such a feature exist?

I am a GA user. yes, there is integration with Cubase. Though I use it in other DAW usually. Checkout the YT tutorials.

Fills can be mapped to midi notes and you can pop in those midi notes in the track wherever you want. I’m not sure that counts as being in conjuncture with the arrangement, though.

Groove Agent integrates well with Cubase, including workflow-enhancing features, such as template-based editing and tight synchronization with arranged music. While it may not exactly match Logic Pro's virtual drummer, Groove Agent allows for customization and automation of drum parts, making it versatile for Cubase users.

Groove Agent does offer some integration with Cubase, including the ability to use it with the Arranger Track for more dynamic drum arrangements. While it may not be exactly like Logic Pro's virtual Drummer, many users find that the flexibility and features in Groove Agent can enhance their workflow in Cubase.
