Korg MicroSampler Review

To everyone’s surprise, Korg has launched a small sampler keyboard. Let’s see what we can do with it and for what purpose…

The first all-in-one sampler keyboard saw the light of day almost 30 years ago. Born under the Californian sun in 1981, the Emulator provided four or eight voices, a four-octave keyboard and 128 KB of RAM that allowed the user to save four seconds of audio data at 8 bits/28 kHz. “Play a turkey” said the ads… you could even play eight turkeys if you paid $15,000! In those days, big Fairchild systems were the rulers and the Synclavier could not sample audio yet. The Ensoniq Mirage was the first to make this concept affordable in 1984. And the arms race began: memory, resolution, sample rate, polyphony, sound synthesis section, effects, sequencer… E-mu, Ensoniq, Kurzweil, Akaï, and Roland became the major players. And Korg joined in the adventure in 1986 with the DSS-1. With the advent of computers and their giant sample banks, the sampler keyboard market reduced to zero, nothing… until recently, when Korg surprised everybody by launching a feather light sampler keyboard called MicroSampler. For whom, for what and how?

A Strange Package

Korg MicroSampler

With almost 4.4 lb., the MicroSampler is no tank! The front panel is made out of gray cheap-looking plastic. All controls are recessed into the housing; this design protects the controls during transportation indeed but it also makes access harder. It is specially troublesome for the “Tap Tempo” and “Sampling” buttons given that we would like to push them more easily! The unit is equipped with six encoders, that recall the program selectors of a washing machine, and 16 switches. The front panel is divided into four main sections: keyboard (that allows sample selection and assignation), pattern sequencer, sampling, and browsing. The latter consists in a backlit LCD, browsing keys and two encoders: the first one allows you to browse the parameters and the other one to edit them. The keyboard offers 37 velocity sensitive keys in small format. The MicroSampler is definitely made for skillful people when it comes to editing and playing, even if the black keys are a bit larger than on most compact keyboards… Right above the keyboard, you’ll find a 37-LED display inserted in a metal bar, which indicates the sample(s) being currently played or edited. By the way, the unit has no joystick nor wheels! On the other hand, it has two slots for a cell phone, a pack of cards, chewing-gums, or money…

On the front panel you can also find an XLR connector for the gooseneck dynamic mic included. All other connections are on the rear panel: headphones out, stereo audio output and input on 1/4″ jacks, Midi in/out, type-D USP port, power in, and on/off switch. The USB port allows you to connect the keyboard to a computer to transfer samples and Midi data (see gray box). Under the hood, there’s a closed compartment for six AA batteries that allow you to play for about four hours (battery indication with visual alert on the display), which is ideal to sample sounds on the beach or in the rain forest… Handling is rather easy and most controls are easily accessible since the unit is very slim. By pushing the “Edit” button and a key you’ll access the edit page directly above it. The only issue arises with the “Value” encoder, which is not absolutely precise for parameter editing. We would have preferred increment/decrement buttons.

Memory and Sound

Korg MicroSampler

The MicroSampler is stereo and has 16 bit/48 kHz resolution, like all Korg products since the Trinity… Its permanent memory allows you to save eight banks of 36 user samples each (160 sec. per bank and only half that in stereo). You can use only one bank at a time after having loaded it into the internal temp memory. We don’t know if audio data is compressed but 15 MB of internal temp memory correspond to 116 MB flash memory, in linear format. The polyphony provides 14 voices but samples that use time stretching require twice as much voices.

The MicroSampler is provided with a sound bank stored in the internal ROM. It includes 36 samples and 16 patterns, some of which you can listen to here (drums, pitched, looped): Not very generous and poor quality… In “sample” mode, you can access the 36 samples dispatched over the whole keyboard in their original pitch, except the higher C key dedicated to the stereo audio input. In “keyboard” mode, the current sample is applied to all 37 keys; the second C from the left corresponds to the original pitch. You can transpose beyond this pitch range, even with an external master keyboard! If other samples are looped while you switch to this mode, they will continue playing back. On the contrary, you have to release the notes to change the sample.

Now let’s take an even closer look…

Conclusion

The MicroSampler revisits a 30-year old concept with modern technologies. The results? Extremely light weight, mobility, permanent memory, real-time sampling, integrated effects, basic sequencer, and connection to a computer. With its small keyboard, basic editing, integrated mic and standalone capability, it will be best used for mobile or live applications; it cannot compete with software solutions in a studio. The ergonomics could be better considering the target users: better access to the controls, remote sampling start, standard-size keys, more banks… Finally, the MicroSampler is a nice compact tool which is less a toy than it seems, and it is just waiting for you to take it for a ride somewhere.

Advantages:

  • Very compact size
  • Easy to use
  • Real-time capability
  • Real-time time stretching
  • Flash memory
  • Comprehensive effects section
  • Memory exchange with a computer
  • Downloadable PC/Mac editor software
  • Wav/Aiff import via editor

Drawbacks:

  • Recessed controls
  • Limited sound synthesis possibilities
  • Proprietary sample format
  • Not conceived for multisamples
  • Playing limited to 37 keys
  • Only one bank in the RAM
  • Limited number of internal banks
  • Limited number of samples per bank
  • No save function for a USB key or a card
  • Almost no pattern editing possibilities
