Mpc1000

Akai MPC1000

The MPC1000 is a 64-track sampler/sequencer. It comes with 16 MB sample memory as standard, and can be expanded to 128 MB. It supports a sampling rate of 44.1 kHz, in stereo or mono. Its features include a USB port, an internal CompactFlash card reader, two MIDI inputs and outputs, and effects and multiple analog outputs as standard. Its sequencer's resolution is 96 ppq.

There have been many reported problems with the pad sensors in the 1000. In the original MPC1000 sensors, a thin square of carbon-impregnated rubber is glued at each corner above a copper coil. When a pad is depressed, this carbon-impregnated rubber is compressed against the copper coil, allowing current to pass through. This moving part can wear out, as the carbon-impregnated rubber sloughs away from the glue and eventually breaks loose.

In 2007, Akai offered a fix for this issue, retailing at 180 USD. The pad sensors design returned to the design of the pad sensors in previous models. This upgrade has been seen to be pre-installed on the MPC1000BK-N and some versions of the MPC1000BK, not the MPC1000 (blue outer casing). Before this change, a MPC1000 user designed, built and sold kits of a pad fix under the name "Nym." Nym's kit is no longer available. By comparison, the more recent Akai pad fix uses better sensor technology (Sensitronic FSRs).[16]

MPC500

Akai MPC500 and others

The MPC500 is the smallest MPC ever made and is the first truly portable MPC created. It can be run on 6 AA batteries but also can be run on a 12V DC plug. It combines a 48-track MIDI sequencer and a 32-voice stereo digital sampler. The MPC500 is the first MPC that only has 12 velocity sensitive rubber pads. It comes with 16 MB RAM but can be upgraded up to 128 MB of RAM. It has a CompactFlash slot for storage of samples. One major appeal of the MPC500 is the fact that you can take a project created on the MPC500 and transfer it to any current MPC with a CompactFlash reader. The MPC500 has a USB port for computer connectivity. It has one stereo output, making it the only MPC currently in production that does not have assignable outputs.
