SX-WSA1

Back in the late '90s, this synth pioneered acoustic modeling by pairing PCM waveform drivers with DSP resonators, letting you pluck a guitar driver into a membrane body for sounds no sample pack could touch.

Its core is a 61-key velocity- and aftertouch-sensitive keyboard with a fast, spongey action that's surprisingly responsive for expressive playing. You get 64-note polyphony across 32 MIDI channels, blending up to four layered tones from 307 drivers and 63 resonators like strings, flares, or plates, all shaped by pitch, comb/resonant filters, amp envelopes, and a shared LFO. Controls shine through a big 320x240 graphic LCD for intuitive editing, realtime knobs for driver/resonator tweaks like position and muting, digital drawbars, and a 16-track sequencer holding 47,000 notes with SMF floppy playback. Three DSP effect blocks offer 43 algorithms plus 12 reverbs, feeding dual stereo outputs and full MIDI I/O for seamless integration.

Players love its orchestra-in-a-box potential, crafting thick pads, realistic acoustics, or wild hybrids that evolve with your touch—though presets can feel thin until you dial in some resonator crosslinking. A rare gem for sound designers chasing organic depth without polyphony limits.
