Korg DSS-1 (1986)

Korg's first sampler weighs 18.5 kilos. It has 12-bit digital sampling, a great analog filter, and a floppy drive that will outlive none of it.

Overview

At 18.5 kilograms, the DSS-1 is not a keyboard you tuck under one arm. It is a 61-key digital/analog hybrid - Korg's first sampling keyboard, released in 1986, and the machine that started the company's long relationship with sampling. It has 12-bit sampling, additive synthesis, and hand-drawn waveform creation, and it runs all of it through an analog filter and VCA. Digital tone generation, analog shaping.

The architecture is unusual. There are two oscillators per voice, up to 8-voice polyphony, sixteen digital oscillators in total, plus a noise source. The filter is analog and switches between 12dB and 24dB modes. The DW series and the Poly-800 don't have that, so the DSS-1 has a wider tonal spread than its stablemates. Two multi-stage envelopes and two triangle-wave LFOs (Korg's "MG") handle modulation, one for pitch and one for filter. The joystick handles pitch bend, vibrato, and filter modulation. Velocity, aftertouch, and key transpose are all programmable.

Sampling runs at 12 bits with a maximum sample rate of 48 kHz, which at the time was ahead of the pack. Output bit resolution can be dropped to 8, 7, or 6 bits if you want grit. Memory runs from 256KB up to 2MB, and the built-in floppy drive stores up to 128 sounds per diskette across four banks (A, B, C, D). The DSS-1 measures 1171 mm wide, 436 mm deep, and 123 mm high. It's a big, flat slab of a keyboard.

By most accounts it is a huge digital/analog sampler with some basic synthesis functions bolted on, and one of the more distinctive instruments Korg built in the mid-'80s. The Sound On Sound retrospective described it as "comparable to a dinosaur, its great bulk and power controlled by a small, rather ponderous brain." That's fair, and it's also why people still seek it out.

Key Features

12-Bit Sampling at 48 kHz

The DSS-1 samples at 12 bits with a maximum sample rate of 48 kHz. Electronics & Music Maker (October 1986) reported that the 12-bit analysis put the DSS-1 on a par with every sampler released that year, while its 48 kHz maximum sample rate put the others in the shade. That's a real spec advantage for 1986. The output resolution is also user-adjustable down to 8, 7, or 6 bits, which is either a fidelity compromise or a tool for grit, depending on what you're after. Modern owners tend to treat the lower settings as the latter.

Analog Filter, Switchable 12dB/24dB

The filter is the heart of the DSS-1's reputation. It's analog, resonant, and switchable between 12dB and 24dB modes, which the DW series and Poly-800 didn't offer. Sound On Sound later called it one of the best low-pass filters Korg ever put in a synthesizer, and said a resonant sweep from the DSS-1 can still put all but the mightiest analog synths to shame. That's a strong claim about a 1986 digital sampler. The VCA is analog too, so the whole signal path after the digital oscillators is shaped in the analog domain.

Two Oscillators Per Voice, Noise, and DWGS Presets

Each voice carries two 12-bit sampled waveforms plus a noise source, with sixteen digital oscillators across the eight-voice polyphony. The DSS-1 also ships with Korg's DWGS synthesizer presets, the digital waveform generation system inherited from the DW-8000 lineage, so you're not starting from an empty sample library. Additive synthesis and hand-drawn waveform creation are both supported, so the DSS-1 is as much a sound-design workstation as a straight sampler.

Onboard Delay/Echo and Auto Bend

Effects are generated internally: delay/echo plus the "Auto Bend" effect that Korg built into the instrument. The delay is part of the DSS-1's voice, and the Auto Bend gives it a characteristic pitch gesture that shows up across a lot of DSS-1 material. Sample editing covers truncate, loop, crossfade, and keymapping, which is the housekeeping you'd expect from a sampler of the era.

Floppy Storage and MIDI

The built-in 3.5-inch floppy drive stores up to 128 sounds per diskette across four banks. MIDI in/out/thru is present, and the implementation is described as advanced for its time. The floppy is also the machine's weak point, more on that below.

Historical Context

The DSS-1 was Korg's initial entry into the sampling market, and it was the company's first sampling keyboard. Along with its rackmount sibling, the DSM-1, it remained Korg's only sampler until 1998, when sampling options arrived on the Triton and Trinity workstations and the Electribe series. That's a twelve-year gap.

The DSS-1 has much in common with Korg's previous flagship DW-8000. One contemporary description called it a DW-8000 "on steroids." Sound On Sound (April 1987) put it ahead of the Emax, Prophet 2000/2002, Ensoniq Mirage, Roland S50, and Akai S900 on signal processing capabilities and performance options.

Collectibility & Value

The DSS-1 sits in the budget/beginner tier of the synthesizer market. It's not a collector's trophy, and prices reflect that. The main problem is practical: the original floppy drive is prone to failure, and a dead drive on a machine that stores its library on disks is a real problem. Replacements from eBay are the standard fix. There's also a free workaround. Systems can be sent over MIDI with a software utility, which takes a couple of minutes to transfer a full system and costs nothing. Owners tend to be honest about its limitations: it isn't hi-fi by modern standards, but it sounds good and has character. The 12-bit sampling and that analog filter are the reasons to own one, and the floppy drive is the reason to budget for maintenance.
