We Made You A Mix Tape
DEM-Osc is a free demo version of the Osc Collection. Despite featuring just half the controls, it remains a powerful instrument on its own. We took time to choose the oscillators from the full collection and ended on these 5 diverse oscillators that form the core of this synthesizer.


True analog sounds. I’ve bought the collection and I love all the instruments provided. They could be simple or complex. It’s all about your imagination. The graphic and the design are top. Presets are really useful as start point for sonic exploration. Work of love for sure.
My review of Pro OSC is also testament to the quality of CHIP OSC, the quality, sound and sheer joy these beautiful synths bring to producing music, is seriously a breath of fresh air.
These CKI synths have totally been the barn find of the decade. When it comes to finding high quality soft synths that sonically impart the level of quality expected of high end synths produce. Totally inspiring!!!
I Stumbled across Clay and Kelsey Instruments by chance, and so glad I did, from the first chord struck I was speechless, we’ll kind of of, the words ‘Oh My Gosh… (swear word) Me’ may of left my lips in pure elation as sonic beauty left my speakers and a grin from ear to ear. Finally softsynths with soul and they sound Stella!!!!! I just purchased an upgrade to Komplete 14 several days prior and have to say, NI as great as it is doesn’t have the immediacy or real Phat Analogue vibes as Clay and Kelsy Instruments. Over the years I’ve found soft synths to be veiled and flat, always sitting back as if the sound stage has already been chosen by the developer, sitting in the 2d realm, Kind of like guitar sims. They sound great when cranked but once the initial ear candy dissolves your left wanting.
Playing Pro OSC is like playing a high end analogue synth the quality and the coding is next level, pure genius!!!! The quality and choice of the convolution fx’s is a breath of fresh air! I can’t wait to see what they come out with next! Insta buy
