Final answer:
In the General MIDI standard, the acoustic grand piano is usually found on channel 1, and drums are on channel 10. Channel 10 is used specifically for percussion instruments in GM-compatible devices.
Step-by-step explanation:
The General MIDI (GM) standard assigns specific programs (sounds) to particular channel numbers to ensure consistency across different synthesizers and sound modules. In the context of the GM standard, the acoustic grand piano is typically set to channel 1. This is where you would expect to find piano sounds in any GM-compatible device. As for drums, they are conventionally located on channel 10. Channel 10 is reserved for percussion instruments, and it is where drum kits can be triggered from. Each key on a keyboard or MIDI controller can correspond to a different percussion sound when played on channel 10.
