📌 At most, the .GRO extension build-up is technically associated with the bitmap image specification frequently entitled as a GROB (GRaphic Object Bitmap). In practice, the current .GRO approach is frequently applied by scientific calculators manufactured by the Hewlett-Packard brand, such as the HP-49 and HP-48. Precisely, the noted .GRO schema is utilized for storing and opening charts, graphs, and other statistical and informational graphics created by the features integrated into the calculator basement. .GRO file arrangement can be easily and fluently viewed on a computer workstation or client using an auxiliary virtual emulator of the HP calculator, such as Emu48.

📌 Instead, the .GRO basement can correlate with a ASCII text file object that defines and opens audio in a MIDI sequence. In detail, this custom .GRO variation also internally covers “note tracks”, which identify display content for the audio composition. At last, the .GRO items can be freely imported (and respectively converted to alternate third-party audio schemas) with the interaction of the primary menu’s File -> Import MIDI… branch node.
📌 Most of the .GRO format instances are available for survey, analysis, and opening due to involvement of Emu48 HP calculator emulating shell, as well as XnViewMP graphical editor and Newera Graphics Converter Pro converter. On rare occasions, it is worth getting closer acquainted with the Audacity audio editor, capable of audibly playing back and reproducing ASCII-shaped MIDI tracks.
