Roland EDIROL R-1 Manual Del Usuario página 71

I used a USB cable to connect the R-1 to my computer, but it
was not detected
If the R-1 is in Setup mode, it will not be detected by your computer. Unplug the USB
cable that connects the R-1 to your computer, exit Setup mode, and make the connection
again.
Refer to: "Connecting the R-1 to your computer" (p. 44)
The effect parameters I edited have been initialized
The effect parameter settings you edit are preserved as long as you don't change the
effect type; if you change the effect type, the settings will revert to the initial values. If
you make detailed changes to an effect such as "Editable EQ," we suggest that you write
down the settings on paper.
"Applying an effect" (p. 52)
Refer to:
When selecting a song, the song names are slow to appear
If a file is damaged or invalid, if an MP3 file is in a format that the R-1 does not support,
or if the file is very large, the R-1 may take some time to determine whether it is able to
play the file even if the file has an extension of .MP3 or .WAV.
This may cause the display to be slow when selecting files.
Refer to: "Types of files that the R-1 can handle" (p. 28)
"Normal playback" (p. 38)
Acoustic feedback occurs when monitoring through
headphones
If you're using open-air type headphones to monitor the sound while recording,
moving close to the R-1 may allow sound from the headphones to be picked up by the
microphones, causing acoustic feedback. The R-1's built-in microphones will pick up
even faint sounds, so be careful not to get too close.
Refer to: "Basic connections" (p. 18)
