Cherished classic Akai MFC42 Analog Filter (Pulled from our AKAI MPC 2000XL system) Rack Filter Unit + Complete radius discography

from echospace [studio]

This unit is from our private studio collection (purchased brand new in 2001) and one of the many filter units used in creating many of the sonic sculptures of the epic radius project. We are currently downsizing for a variety of reasons and prefer to offer our fans and supporters a chance to acquire this beloved and cherished filter from our studio as we would prefer it be in "like-minded" hands who will make good use of it. This unit has been kept in a non-smoking studio environment and has been used on more records and productions of ours than we can mention, it truly has that "smooth as butter" character you would hope for from a true analog filter. We're truly hoping this unit finds a good home and one which will love and care for it as we have, this piece is really something special.

The MFC42 is a true analog filter module designed by Akai for their MPC-series gear. However, you can use it to process any sound source since it has basic 1/4" inputs and outputs and MIDI! It has genuine analog filters for that warmer tone with Lowpass, Highpass, Bandpass, and Notch filter types. It consists of a MONO filter section and STEREO filter section. The MONO section offers 2-, 4-, and 8-pole filter slopes. The STEREO section offers 2- and 4-pole filter slopes. The MONO 8-pole slope utilizes the whole filter circuitry so the STEREO section is not active. Likewise, the MONO section is inactive when the STEREO section is in 4-pole mode. But when both sections are used simultaneously, they can be linked so that the MONO filter's control knobs control both MONO and STEREO sections. The link can also be inverted so the two sections sweep in opposite directions.

Other features include one ADSR envelope for the filter's contour. This envelope can be triggered by MIDI and Trigger button, but not by audio unfortunately. The LFO is essential to bringing this filter to life! It has four waveforms including sawtooth, square, triangle and random. It can be synced to MIDI clock and can modulate to 16th, 8th, 1/4, 1/2, whole, double-whole, and triplet notes in tempo with your MPC (or MIDI) sequences! Or use the "Tap" button to tap in the tempo in real-time. A large numeric display shows the current tempo and there's also an EQ on-board for global sonic fine-tuning. Effects include a very harsh (in a good way) Distortion and stereo analog Phase Shifter. The ins-and-outs consist of three 1/4" inputs (mono/stereo), stereo phono (RCA) inputs, stereo 1/4" outputs, stereo phono (RCA) outputs, and MIDI in, out and through. All pertinent knobs and buttons can send and receive MIDI control.
