Send OSC list to Reaper to write automations

[tomson_fauster]

Hi to all!

I would like to ask you a question about OSC.

Is there a method, utilizing Reaper Actions or alternative approaches, to transmit a list of OSC data, each comprising a timeline and three additional variables, from another application?
This list will be used to write/overwrite automation within the Reaper session.


I think including the timeline within the OSC message is crucial since each timestamp in the OSC data needs to align with the current Reaper timeline.

Thank you all for the help!

What do you mean by a "timeline in OSC" ? AFAIK, OSC is dedicatedly a realtime protocol for single events.

I try to explain the issue better.
I would like to send a list (or a single event at a time; it doesn't matter) from Unity software (in this case) to Reaper.

I would like to save coordinates in Unity with time stamps (e.g., 0 sec, variable 1, var2, var3; first sec, var1, var2, var3, etc., where the values change over time).
I would like these variables to override my automation of 3 variables in a Reaper plugin along its timeline, taking as reference the timestamp of the list I made on Unity and then putting at second0 the values that are in var1, var2, var3, then at second1 change those values with the 1st-second values of the variables and so on).

It is indifferent whether to send a complete list or a single event at a time (timestamp, var1,var2,var3).

What I would like to do, however, is to do some interactions in Unity for 30 seconds and send some coordinates (rescaled and adequately mapped) into Reaper to have it write the automation explained earlier in the 30-second timeline.


I hope I have explained the issue better.
Thank you very much for your help.

Time stamps being sent in a realtime protocol like OSC does not seem to make sense.

Do you have any advice on how to achieve what I have written?
Thanks in advance!

If I understand correctly it's not possible to send such via OSC by means of any usual OSC usage guidelines.

OTOH, any device is free to send just anything via OSC, as there is no mandatory definition of the content of OSC messages.

ReaLearn or OSCIIBot are two Reaper-related propgrams I know that might be able to receive and decode such messages and maybe allow to do something sensible with the content.

Thank you very much!

I have tried the different actions (see the attachment), and indeed, none allow me to "write" the points as I want (based on an external controller, like a MIDI controller, or just sent points from another software via OSC).

Effectively, most of these actions only allow one to write the current value. I don't know if you know of any other actions as well.

I will now investigate further in the forum if anyone has experience with my issue.
I thought what I had in mind to do was possible with the actions, leaving out the timeline thing.


Anyway, thank you again for the help!

This is exactly what OSC is designed for.

Essentially, you'd want to write a sequencer inside Unity itself to handle the sequencing of the control messages being sent to Reaper.
