Product Description The Akai Professional MPC2500 Music Production Center combines a 64-Track MIDI Sequencer with a 32-voice 16bit Stereo Digital Sampler. The MPC is a rock solid sequencing and drum programming machine with 16 velocity and pressure sensitive rubber pads. The unit allows you to sample more efficiently. This composition center is contained in one extremely powerful desktop unit. Designed for professional audio production, the MPC2500’s intuitive and ergonomic interface makes it the ultimate user friendly composition studio Two internal effects processors can be used simultaneously. This includes a wide range of effects algorithms, such as reverb, bit grunger, chorus, phasers, flying pan, 4-band EQ, compressor, and a phase shifter. Real-time control is provided by two note variation sliders and two Q-Link knobs. Q-link knobs can be separately assigned to allow flexible, real-time performance control of a wide variety of selectable parameters. These parameters include level, pan, filter cut-off and resonance, tuning, LFO(low frequency oscillator) speed depth, all effect parameters and more. Each assignable Q-Link knob can generate MIDI controller data so that all performance information can be recorded and played back from within a sequence. The Q-Link sequencer allows cyclic modulation programming. Following the highly acclaimed MPC60 and MPC3000, 2 MIDI inputs and 4 MIDI outputs come standard enabling 64 external MIDI channel operation. In addition, the MPC2500 can individually control its onboard sampler up to 64 Parts, allowing users to assign a different program on each track. A large LCD screen allows a clear view of sequence data displaying features such as a piano roll, or a drum machine 'grid'. Continuous MIDI data can be shown as well as edited graphically. The MPC2500 comes with 16MB of onboard memory which can be expanded up to 128 MB of RAM via the optional EXM128 memory card. The MPC2500 has the capability of an optional internal 80GB Hard Disk and CD-RW drives. Positioning Akai Professional, in its pursuit to remain the leader of digital sampling technology has released the MPC 2500. This unit designed for professional audio production, offers drum programming, sequencing, and sampling capabilities. Artists now have the luxury of producing music with a compact music composition center.
