Is it OK to remove the SD card while using the [USER] mode?

There is no problem removing the SD card during playback. For the effects, the program operates using the parameters stored on the RMX-1000 for the [USER] mode. For the samples, the default sound sources (KICK, SNARE, CLAP and HI HAT) are used.
The [USER] mode set upon shipment from the factory has the same parameters as the [DEFAULT] mode.
When using the remixbox’s SYNC function, the customized parameter data set with remixbox is loaded into the RMX-1000 and these parameters are reflected in the [USER] mode.

The data may be damaged if the SD card is removed while customized parameter data is being stored on it, but the data is not damaged if the SD card is removed during playback.
