Critic Reviews

Casio SK-1 (IM Nov 86)

muzines.co.uk

The Casio SK-1 is a charmingly compact and affordable sampler that offers a playful introduction to sampling and synthesis. While its low price makes it accessible, the trade-offs are evident in its 1.4-second sample time and modest 9.35kHz sampling rate, which limit its audio quality and musical versatility. This mini keyboard excels as a fun tool for capturing quirky sounds and adding unique textures to your music, but it falls short as a serious sampling instrument. With its basic additive synthesis and limited polyphony, the SK-1 is more of a novelty piece for hobbyists and novices than a professional-grade sampler.

Wonderful

I got the SK-1 from Christmas and have since fallen in love with it. In my opinion every downside makes it a little better(besides quality of course). The Short and lo-fi samples can make some truly beautiful sounds especially with pedals, and for quite cheap. And you can make some surprisingly complex drums by just running it through a delay. Also from what I've heard easy to mod. Really my only gripe with it is the quality, which is completely reasonable considering it's from the 80's and was originally meant to be a toy for kids. But all in all I think it's perfect.

"Cult classic" for the sake of being a "Cult classic"

The Casio SK-1 really is what it is. Very basic lofi sampler that almost has an internet Cult following but none at the same time. It's fun to play with for an hour or so and makes some nice lofi bell/mallet sounds but that's about it.

The "sequencer" features are actually quite neat but nothing to really write home about.

lowest of lo-fi

I've been looking for one of these for a few years now, ever since I heard the music in Homestar Runner was made with one, but the prices on Ebay and Reverb are just way too high because of circuit benders and hipster indie bands. 75 dollars for one of these is fucking crazy, but if you can find one at an antique/thrift/junk shop, get it! The built in sounds are pretty typical of kids Casios from this era, but the sampler is so crunchy, it's great. It only has about a second and a half of sample time, but if you pull the classic SP-1200 trick of speeding a record up to 45, you can just barely fit a drum break in there, which sounds great under house drums, a la Fresh & Low's Wind On Water (https://youtu.be/e1X59TH8IxI)

This sampler gave me a 35 year career...

In 1985 I was 15 years old and I produced the A-Side of my very first vinyl release Choice M.C. "Let's Make Some Noise" on Idlers/Warlock Records with the Casio SK-1 and Casio RZ-1. It's not the greatest sounding sampler, but it has its own character and I used it again on the sequel record "Let's Make Some Noise Part 2" released by 12-Bit Records. This sampler some consider a toy has blown up in the circuit bending movement, and strangely enough a few boom bap producers reached out to me to ask if I really used this on my earlier records and my answer to them is often "I still use it"...

A great tiny keyboard

I really enjoy messing around on this thing. It’s a great size for traveling and has some really great sound’s especially if you use the sampler. The only downside is it’s key size, the keys are extremely small which can be fairly challenging for people with big fingers.

$2 at Goodwill? Worth it!

This was a steal at a local thrift store. I originally intended to circuit bend it, however as I played around with it I found it has great capabilities in it's original form. The sampling function is probably my go-to use for this instrument, but the built-in effects, "sound design" option, and present voices are worth exploring as well.

Perfect for portable playing whenever I want.

I can create any sound I want. Playing around with it for a while really inspires me to make more music, and more sounds, even with other instruments!

I have two of these lo-fi sampling keyboards, and rarely use them as of late, but the low fidelity gritty quality is quite nice. I plan on using them more in the distant future.
