Released in 1986, the Roland MKS-20 was part of Roland’s “MKS” series of rackmount sound modules. Unlike sample-based pianos (which were still primitive and RAM-expensive), the MKS-20 used structured adaptive synthesis. This was an early form of physical modeling combined with ROM waveforms.
A lot of vintage gear problems get blamed on electrolytic capacitors. The MKS-20 suffers from that, too, but the "Crackle" is different. It points to two specific gremlins:

By the mid-1980s, Roland had already changed the piano game. The RD-1000 and MKS-20 (its rackmount sibling) didn't use sampling. Instead, they employed structured adaptive synthesis — a clever blend of algorithms and subtle filtering to create piano, vibes, and electric piano sounds that felt alive. For its time, the MKS-20 was a revelation: warm, responsive, and capable of cutting through a dense pop or jazz mix without sounding brittle.
But nearly 40 years later, owners of the MKS-20 are facing a creeping dread: the MKSensation crack. Released in 1986, the Roland MKS-20 was part
There are few pieces of gear in the used market that command as much quiet respect as the Roland MKS-20.
Released in 1986, this 1U rack module was the heart of the "digital piano" revolution. Before samples, before modeling, there was the MKS-20. You’ve heard it a thousand times. That glassy, percussive, impossibly clean electric piano sound on Every Breath You Take? That’s the MKS-20’s "SA (Structured Adaptive) Piano." The bright, bell-like DX7-meets-acoustic tone on 80s power ballads? Almost certainly an MKS-20. In short: The digital logic is fine
But owning a vintage legend comes with a catch. A specific, frustrating, and uniquely named catch: The MKSensation Crackle.
First, let’s geek out on why we tolerate this machine’s quirks.
Unlike modern sample-based modules, the MKS-20 uses structured synthesis. Roland analyzed how a piano's timbre changes from ppp to fff and created a digital algorithm to mimic that harmonic evolution. The result is not "realistic" by 2024 standards—it sounds nothing like a Steinway in a concert hall. Instead, it sounds like a record. It sits in a mix like butter. It has an inherent 12-bit grit and a "plink" that makes producers smile.
It is the sound of Miami Vice, Prince’s Sign o’ the Times, and every late-night adult contemporary ballad.
