The S90 Shop (S-Mart) is an authorized Yamaha dealer, an independent e-store devoted to products and accessories that relate to the Yamaha S90 and S90ES.

We specialize in products that are either impossible to find elsewhere, such as new Voice Banks and Arpeggios, or close to impossible, such as books, DVDs, storage media, cases, and expansion boards. 

This is the #1 support site for Yamaha's S90 series.  All products in the S-Mart are in stock unless they are specifically, and temporarily marked back-ordered. All items are also guaranteed to work on your S90/ES, can be delivered  worldwide in a range of customizable options, and are fully supported by the knowledgeable and friendly people here at Keyfax. 

Keyfax NewMedia Inc.was founded in 1994, producing the Twiddly.Bits MIDI Sample libraries, which can be used on any sequencer (including your bundled SQ01) and which, incidentally, will sound wonderful utilizing S90/ES voices. 

Songwriter’s Drums, released Summer 2004, is a custom S90 collection of drum beats taken from the Twiddly.Bits libraries that you can call up and use directly on S90 from SmartMedia Card or from USB device on an S90ES.
