Linn MPC-60
A 10.5 kg slab of 1980s sequencing ambition with sixteen pressure-sensitive pads and four independent MIDI outs.
Overview
The first thing you notice is the weight: 10.5 kg, in a case 495 mm wide, 127 mm tall, and 471 mm deep. You don't tuck this under an arm. It's a workstation, and it wants a permanent spot in the studio. Inside is an 80186 processor running at 10 MHz, a 320-character graphics LCD, and a 3.5-inch 2DD disk drive with a formatted capacity of 793K bytes. The sampler runs a fixed 40 kHz sampling rate and captures 13.1 seconds of audio in its standard 750K-byte configuration. The EXM003 sound memory expansion doubles that to 26.2 seconds. Frequency response is quoted at 20 Hz to 18 kHz. The converters are 16-bit on both the A/D and D/A sides, and samples are stored in a nonlinear 12-bit format that the manual claims gives lower noise than linear 12-bit systems. Sixteen voices can sound at once, drawn from a maximum of 32 drum sounds held in memory.
The sequencer is where the MPC-60 earns its keep. Note capacity is 60,000 notes, not events, with timing resolution of 96 divisions per quarter note. You get 99 sequences in memory, each with up to 99 simultaneous tracks, plus song mode covering 20 songs at 256 steps apiece. There are 64 output MIDI channels. The rear panel carries four fully independent and simultaneous MIDI outputs and a single MIDI input. Sync options are unusually broad for the period: SMPTE, MIDI Time Code, MIDI Clock, MIDI Song Position Pointer, FSK24, pulse, and quarter-note clicks. There are two foot switch inputs, both independently assignable, and an RS-232C computer port. The sixteen drum pads respond to both velocity and pressure.
The timing correction is the detail that sets the MPC-60 apart from its contemporaries. Many sequencers truncated or stretched notes. This machine corrects only the note attacks and moves the note endings along with them, so duration is preserved. Continuous events like pitch bends are recorded exactly as played and left uncorrected. A keyboard solo's notes can snap to the grid while the bends stay fluid. Six note values are available for correction, or it can be turned off entirely, and previously recorded notes can be corrected after the fact.
The rear panel has a lot on it. There is one record input with a three-position gain switch (HI, MID, LO) and a balanced input at 45K impedance on all three settings. There are eight assignable mix outputs at 0 dBv into 600 ohms and two stereo outputs at -3 dBv. A dedicated echo send mixer output sits at -1.5 dBv with its own level control, along with two echo return inputs at 10K impedance. The sync input is dual-function and balanced, accepting 0.5V to 1V peak-to-peak, and the sync output is 1V peak-to-peak into 220 ohms. There's a metronome output for clocks. Power consumption is modest for the size: 30 W at AC 100V, 32 W at 120V, 220V, or 240V depending on region. Some units have a rear-panel voltage selector and others are preset at the factory.
For all the specs, the machine was designed to be learned by doing. The manual opens by admitting it was written for people who don't like reading manuals. The recommended workflow is to press the key that seems most likely to hold the function you want, follow the on-screen prompts, and hold the HELP key when confused. The system's own documentation concedes the MPC-60 is "a very complex product," and that complexity extended to the software. Akai acknowledged that with thousands of possible usage paths, bugs could slip through testing. The company periodically released software updates, which were simple to install, but users had to contact dealers or service centers to confirm whether their machine had the latest revision. By the manual's own admission, duplicating a bug's exact trigger sequence was sometimes extremely difficult.
Period documentation puts the MPC-60 in working studios rather than bedrooms. Recording Engineer (March 1988, p.95) noted that Memphis Sound Productions had taken delivery of an Akai-Linn MPC-60 sequencer/drum sampler, loaded with sounds donated by percussionist Terry Elam. The same column called it a sequencer/drum sampler, which is the accurate framing. It was never just a drum machine. By 1991, EQ Magazine (June 1991, p.22) listed a Linn-Akai MPC 60 in the keyboard and sampler rig at Axel Kroell's Baby Studio at European American Recording in New York. It sat alongside an Akai S1000, two S-900s, a Linn 9000, and a stack of Roland and Yamaha synths. It was the sequencing brain in rooms that also owned dedicated rack samplers.
Anyone buying one today should expect to service it. The manual's troubleshooting section is blunt: read the relevant manual passage thoroughly and slowly before concluding something is broken, because the machine's complexity makes false alarms common. If a real fault exists, write down every detail of the problem and call a dealer, service center, or distributor, who would attempt a phone diagnosis before arranging repair. Akai explicitly warned against unauthorized disassembly, since the internal parts carry serious shock risk. The care instructions are period-typical: no DC power sources, keep it ventilated and out of direct sunlight, away from heat and spray insecticides, and never clean the finish with denatured alcohol or paint thinner. The 3.5-inch disk drive is a mechanical wear item on any machine of this age, and the 793K formatted capacity means sample libraries and sequences were spread across a stack of 2DD floppies.
Collectors note that the MPC-60 sits in an odd spot in the Linn lineage. The brand catalog already carries the LinnDrum, LinnDrum Midistudio, and LM-1, the machines that made Linn's name in drum sounds. The MPC-60 is where sequencing, sampling, and pad performance got combined in one box. The four independent MIDI outs make it a serious multi-timbral controller in a way most period drum machines were not, and the 60,000-note capacity was not a rounded-up figure.
