(A) Hardware-software schematic. MIDI keystroke data (solid black arrows) from duet pianists are merged and sent to FTAP software running the LSL library in a Linux OS. LSL sends MIDI time-stamps over the Local Area Network (LAN, dashed black arrows) to LabRecorder software, where timestamps are recorded as keystroke event triggers. EEG data streams (dotted green arrows) from duet pianists are sent via Bluetooth to SmartingLSL software running the LSL Library in a Windows OS. LSL sends EEG data streams to LabRecorder software. LabRecorder software synchronizes MIDI and EEG data streams by correcting for clock offsets between respective data acquisition computers (Linux/Windows). Synchronized data streams are stored in a single XDF file for storage. (B) Order of Experimental Tasks.
