An Overview of the MC-909
An Overview of the
MC-909
Regarding the locations where samples are stored
The MC-909 can use two types of memory; sample memory and DIMM whose contents are lost
when you turn off the power, and user area and memory card whose contents are preserved even
when the power is off.
When shipped from the factory, the MC-909 has 16 MB of sample memory and 16 MB of user
area. By adding a DIMM module you can expand the sample memory to a maximum of 272 MB
(if a 256 MB DIMM is used).
The user area can hold up to 16 MB, but by using a memory card you can store a maximum of 128
MB in addition to the user area.
When you record a sample on the MC-909 or play a patch that uses a sample, the sample is
loaded into sample memory (including the DIMM). However when you turn off the power,
the contents of the sample memory and DIMM will be lost. This means that if you want to
keep the sample, you must use the Write operation to save it in the user area or on a
memory card.
When managing data from your computer or from the MC-909’s Utility menu, you can manage
only the data located in the user area or the memory card. You cannot manage data that is located
in sample memory or DIMM.

Be aware that because of this, the MC-909 can play samples larger than 128 MB, but
cannot save
samples larger than 128 MB
