Internal Memory and File Management

As you use the DTXTREME III, you’ll create many different kinds of data, including Drum Kits, Drum Voices, Songs and Chain programs. This section describes how to maintain the various types of data and use the memory devices/media for storing them.

Data Lost and Retained When Power is Turned Off

The chart below lists the data types you can create on the instrument and the internal memory locations to which they are stored, permanently or temporarily. Keep in mind that certain types of data are lost when you turn off the power and you should always prepare a USB storage device for use BEFORE you start creating or editing data.

Data types	Internal memory types to which
	data is stored
Drum Kit	Flash ROM
Click settings	Flash ROM
Trigger Setups	Flash ROM
Utility settings	Flash ROM
Chain	Flash ROM
User Song	DRAM
	→ Will be lost when turning the power off!
User Voice	DIMM
	→ Will be lost when turning the power off!

CAUTION

•Among the data types above, the User Song and User Voice data should be saved to a USB storage device connected to the USB TO DEVICE connector before turning the power off. Otherwise, the cre- ated data will be lost.

Internal Memory

Below are explanations of the basic terms used in the Memory Structure illustration on the next page.

●Flash ROM

ROM (Read Only Memory) is memory designed specifi- cally for reading out data, and as such data cannot be written to it. Unlike conventional ROM, Flash ROM can be overwritten – allowing you to store your own original data. The contents of Flash ROM are maintained even when the power is turned off.

●DRAM

RAM (Random Access Memory) is memory designed spe- cifically for data writing and data reading operations. There are two different kinds of RAM, depending on the condition for storing the data: SRAM (Static RAM) and DRAM (Dynamic RAM). The created data stored on DRAM is lost when the power is turned off. Because of this, you should always store any data residing in DRAM to the USB storage device before turning off the power.

●DIMM (sold separately)

DIMM modules must be installed in order for using the Sampling function or for loading audio data (User Voice/ WAV file/AIFF file) to the instrument. As with DRAM described above, the created data stored on DIMM is lost when the power is turned off. Because of this, you should always store any data residing in DIMM to the USB storage device before turning off the power.

●User Memory

The internal memory to which all the data you have created can be stored, permanently or temporarily is referred to as “User Memory.”

Among various types of data created on the DTXTREME III, data stored on Flash ROM can be maintained even if you turn the power off. On the other hand, data on DRAM (User Song) and DIMM (User Voice) should be saved to the USB storage device before turning the power off because these types of data will be lost when you turn the power off.
