Back in 1990, this 1U rackmount module brought Yamaha's cutting-edge AWM2 tech to studios everywhere, packing 2MB of 16-bit samples into a compact 4.2kg chassis that fit right into any setup.
At its core, it runs on Advanced Wave Memory 2, layering up to 4 PCM elements per voice from 74 waveforms—50 acoustic, 16 drums, 8 digital—all sampled at 32/48kHz for crisp playback with 16-voice polyphony that dynamically allocates across 16 multitimbral parts. Shape tones with dual resonant digital filters in cascade (HP/LP and LP, both 12dB/oct slope), a versatile LFO routing to pitch, amplitude, or cutoff, and three multi-stage envelope generators per element: amplitude (4 segments + levels), pitch, and dual filter envelopes with velocity scaling and breakpoints. Tweak via the 16x2 LCD, 18 buttons, and data wheel, then polish with 34 programmable effects like 8 reverbs, delays, stereo panning, gate, and distortion; pan and assign to its stereo outs. Expansion slots take waveform and data cards, while 64 ROM/user voices and 16 ROM/RAM performances keep things organized.
Players love its ambient pads and new-age leads that still cut through mixes today, praising the deep editing for custom sounds beyond dated acoustic presets—though some note the polyphony limits complex layers. A reliable workhorse for MIDI rigs that rewards hands-on tweaking.
