Expand your imagination

The Kronos music workstation was unveiled in 2011 to widespread critical acclaim, winning one award after another. Impressed players, composers and sound designers alike kept asking, "How can they possibly improve on this?!" In the year since its inception, we've done just that. With newly released system updates and an inspiring and growing array of Kronos Sound Libraries, we've brought Kronos to an even higher level of performance.

The Kronos continues its evolution with the new Kronos X Music Workstation. With a boost to the internal memory and SSD size, the Kronos X is the ultimate workstation. Fittingly, its new name adds an "X" to indicate its expanded and truly limitless potential.

Kronos X Highlights

Peerless synthesizer containing nine sound engines, such as realistic piano, richly expressive electric piano, tonewheel organ, digital synthesis, and powerful analog/physical modeling.

Approximately 2GB of available PCM RAM allows more sample data to be loaded at once.

Doubled SSD capacity of 62 GB allows support for gigantic sound library expansions, such as the Kronos Sound Libraries and the KARO Sound Libraries.

User Sample Bank feature allows users to create extremely large sample libraries that take advantage of the generous PCM RAM and SSD capacity.

Numerous artist signature sounds created by top musicians are included, letting you make the sounds of classic songs your very own.

16-part Combis allow all engines to function together in perfect harmony;
Dynamic Voice Allocation keeps the polyphony high.

Store Information

Keyboard Corner was established in the late 1970's. The store had fairly modest beginnings, with a small corner shop, selling mainly organs and pianos. Over the decades our product range expanded greatly.

In the mid 90's we opened KC's Rock Shop, (Keyboard Corner's Rock Shop) to give us the ability to specialize in items other than keyboard based instruments. The two shops are now merged into one building with over 250 square metres of showroom.

December 2012 saw the opening of our specialised drum store, at 15 Erica Ave, just a 1 minute walk from the main store. With a great range of electric and acoustic kits, heads, percussion, cymbals, sticks and accessories we are well worth a visit.

We carry a huge range of everything musical and have specialised departments for pianos, keyboards, digital pianos, sheet music, electric guitars, amplifiers, acoustic guitars, bass guitars, classical guitars, PA gear, home recording, microphones, drums and more.

We have become one of the largest musical instrument suppliers in Melbournes suburbs, and have established a reputation of offering the best advice and service, while still offering great value pricing.
