Since the beginning of the lockdown I have been working hard on a new object-oriented interface to the online database ODB. I have the code now in an initial

testing and commenting. The basic idea is that there is an object midas::odb, which represents a value or a sub-tree in the ODB. Reading, writing and watching |

|
If you load a file into the sequencer from the web interface, you get a list of all files in that directory.
This basically gives you a list of possible sequencer files. It's even more powerful, since you can
create subdirectories and thus group the sequencer files. Attached an example from our

Hi Marius,
your fix is good. Thanks for digging out this deep-lying issue, which would have haunted us if we would not fix it.

Few comments:
- As KO write, we might need semaphores also on a remote front-end, in case several programs share the same hardware. So it should work and cm_get_path() |

18 Jun 2020, Stefan Ritt, Forum, ODB key length

No. But if you need more than 32 characters, you do something wrong. The
information you want to put into the ODB key name should probably be stored in
