OSC Message Receiver Alpha Absolute.

[ellis_alcatraz]

Hi All,

I'm using a Muse S headband and receiving OSC messages from mind monitor into a Max MSP device I've created. Right now I'm only receiving messages that follow "/muse/elements/alpha_absolute". In the app settings I have toggled off Delta Theta Beta and Gama. I also have Average selected in the OSC Stream Brainwaves section. The first value I am receiving is between 0.0 and 1.0 which is expected however I cannot determine what the following 5 values are. Does anyone here know? They look like DC offset raw EEG values but the documentation doesn't specify. And if they are DC offset raw values, how do i know what electrodes they correspond to given there are 4 electrodes + 2 aux channels? If these values are raw EEG signals, I'd expect to see 6 values after the first float, not 5. The following is an example of a message I have received

/muse/elements/alpha_absolute 0.340111 780.073242 764.358948 906.190491 842.93042 750.659363

Thanks,
Ellis

Check https://mind-monitor.com/FAQ.php#oscspec for the spec.

Those other four values look like RAW EEG to me. They are not sent on that path, so I think you have a bug in your code. They should be received on "/muse/eeg".

Also note that alpha_absolute is usually in the range of {-1:+1}, but can go outside this.
