Gleb Rogozinsky developed a command-line utility for the csound/csound repository that converts MIDI files from the SMF0 to SMF1 format, introducing per-channel selection to streamline MIDI workflows. Using C and leveraging skills in data structures, file I/O, and the MIDI file format, Gleb engineered the tool to group MIDI events by channel and output them as separate tracks in the SMF1 file. This approach reduced manual file handling and enabled targeted channel output, enhancing automation potential for downstream processing. The work demonstrated a focused, in-depth solution to a specific workflow challenge, with clear integration into existing system programming practices.
