The Yamaha Music Synthesizer S90 is a synthesizer and a MIDI controller in one unit, released in 2002 to supersede the S80.[2][3] As such, it is part of the S series[4] together with the S03 and S08. It was superseded by the S90ES in 2005, itself superseded by the S90XS in 2009.
The S90 provides 88 fully weighted keys, the number equivalent to a standard piano, emulating the pianistic mechanism.[5] The keyboard naturally provides initial touch, but also aftertouch response and has a 64-note polyphony[6] with 16 multitimbral parts providing a maximum of 4 performance parts.
There are 384 normal (e.g. instrumental) presets and 48 drum kits. The S90 also includes standard GM presets. User presets are 128 normal and 16 drum kits. Presets may be expanded through up to three plug-in boards allowing a bank of 64 presets for each plug-in slot.[5]
The S90 can be expanded through plug-in boards at three plug-in slots, thus providing additional presets, polyphony, effects and synthesizer functionality. Also, a memory slot is included for SmartMedia (3.3 V) cards up to 128 MB.
The S90 is a large black synthesizer with brown side panels and might give the impression of a digital synthesizer with its green display. 71 push buttons are distributed across the front panel, save for the power switch on the back. Pitch bend and modulation wheels are placed above the keyboard aligned to the left.
