Hi Eric,
It is possible to record all audio before and after processing as multitrack recording, each track is recorded in a file.
You can record a performance of more than one hour… We do not offer the possibility to record the automation, but, as you record all audio of the performance, you can edit the files in an editor and fix some mistakes.
Logelloop can be synchronized with Ableton Link.
You can use M4L devices in Logelloop but their utilization is very limited. If you make M4L devices with max, you will be able to make your own LFX and SFX plugs for Logelloop.
Best,
Philippe
