Introduction
Program
Once you assign samples to the pads in the PROGRAM mode,
you can play those samples with the pads. A set of 64 pads,
each assigned samples, is called the Program. The program also
has features that allow you to control the sound of samples, such
as envelop and filter. You can make settings separately for each
pad.
RAM
RAM (Random Access Memory) is a space where you can load sounds or data temporarily. The MPC1000
comes with 16 MB (megabyte) of RAM that can record up to 136 seconds (monaural recording). The MB is a unit
that represents the size of the memory. With the optional EXM128, you can increase your memory to 128MB.
The data loaded in the RAM will be deleted when you turn off the MPC1000. If you wish to save your recordings,
you need to save on a memory card, or transfer the data to PC through USB.
Memory Card
The MPC1000 has a 32MB compact flash memory card. Compact Flash is a memory that is called "Flash
Memory" .You can save the data on the flash memory like RAM, but the data will remain after you turn off the
unit. By saving the recordings in the MPC1000's RAM on the Memory card, you can save the data after you turn
off the MPC1000. Please note that the MPC1000 cannot play back the data directly from a memory card. You
have to load the data from a card to RAM to play back. There are several kinds of flash memory cards, but
MPC1000 uses "compact flash" memory cards.
