All you need to do is to connect it to the device output, for example using DeviceSet or directly the device driver element or reuse the BioEra example with 2 channel training. It is also good idea to connect a Filter in between for the range you are interest e.g. alpha to measure alpha coherence. The output in the range of 0..1, so simply set this range in the Oscilloscope which you connect to output of the coherence object. Hope this helps. Jarek

This will save in a file you choose with .edf extension. Then, to replay you can switch DeviceSet source to the \"EDF file\" and use the recorded file as a source. Preferably you want to set the EDF file name which doesn't change (select \"overwrite\" option in the EDFFileWriter, so that you don't have to select the source file again. The On/Off input of the midi doesn't play the sound, it only enables/disables it. You need to send a value to the \"Pitch\" input.
