The Yamaha Motif-Rack ES represents a significant evolution of the original Motif Rack, addressing critical timing issues while introducing substantial enhancements that make it an exceptionally versatile and professional synthesizer module. This 16-part multitimbral synth module employs Yamaha's established AWM2 sample-based subtractive synthesis technology, delivering up to 128 notes of polyphony with the potential for much more when expanded with PLG boards.

Key Improvements Over Original Motif Rack

The most crucial improvement in the ES model is the complete resolution of the MIDI timing problems that plagued the original Motif Rack. Extensive testing revealed that the ES now maintains timing accuracy within 4-6ms compared to virtual instruments, making it suitable for professional sequencer-based production work. The module performs consistently whether connected via traditional MIDI or USB, and maintains timing accuracy regardless of track position in sequencer applications.

Sound Architecture & Synthesis

The Motif Rack ES utilizes Yamaha's AWM2 synthesis engine with a substantial 175MB wave memory containing 1,859 waveforms. Each Voice consists of up to four Elements (functioning as oscillators) that can be split or layered, with each Voice capable of utilizing up to two insert effects. The module's sound palette draws from a carefully curated collection of samples that span multiple musical genres, from progressive rock and electronic music to more experimental sonic territories.

Voices can be played individually or organized into Performances (layering up to four Voices on a single MIDI channel) or Multis (utilizing separate MIDI channels for full 16-part multitimbral operation). The ES now allows detailed Multi-part editing at the Element level, similar to Roland's JV/XP/XV series, though drum parts remain limited to Common-level editing within Multis.

Enhanced Effects Processing

The effects capabilities represent a major advancement, with the number of insert effects increased from 107 to 116 types. Most significantly, Multi mode now supports up to eight simultaneous insert effect pairs, doubling the original Rack's capacity of four. This is complemented by 20 reverb types and 49 chorus effects (increased from 44) that serve as global effects accessible to all 16 parts.

A new Master Effects section provides eight effect types including a multi-band compressor, delay, lo-fi processing, distortion, dynamic filter, ring modulator, and audio slicing effects. These can be applied across the stereo output in Voice mode or configured individually for each Multi. Additionally, a comprehensive five-band Master EQ (with switchable shelving/peaking options) provides final output shaping, working alongside the existing two-band per-Element EQ and three-band per-Part EQ in Multis.

Expanded Memory & Organization

The preset library has been substantially expanded with six Preset banks plus one GM bank, totaling 896 preset voices, compared to the original's more limited selection. User memory now includes three banks providing 384 user voices, while drum kit storage remains at 65 presets and 32 user kits.

The organization of Performances and Multis has been completely restructured for improved usability. Rather than the original's somewhat confusing bank arrangement, the ES provides clearly separated Performance and Multi banks, each containing 128 presets that can be overwritten, making the system much more intuitive for long-term use.

Advanced Arpeggiator

The arpeggiator has been dramatically enhanced from 256 to 1,787 patterns, organized into 18 categories. These include traditional arpeggios, complete musical phrases, lead lines, bass patterns, guitar strums, drum sequences, and controller-only patterns for creating gated effects. Up to five arpeggio patterns can be assigned to each Voice, Performance, or Multi, with seamless switching between patterns either manually or via MIDI control change messages.

USB Connectivity & Expansion

The USB implementation provides eight virtual MIDI ports, enabling sophisticated routing possibilities especially when PLG expansion boards are installed. With a PLG100XG board and one additional PLG board installed, the system can operate on up to 33 MIDI channels simultaneously, with the PLG100XG providing its own independent 16-channel multitimbral capability.

Available PLG expansion boards include the PLG150AP (Yamaha CF3S concert grand piano with 64-voice polyphony), PLG150AN (analog physical modeling), PLG150PF (pianos), PLG150DX (FM synthesis), PLG150VL (acoustic modeling), PLG150DR (drums with dedicated effects), PLG150PC (percussion with dedicated effects), and PLG100XG (XG/GM synthesis). Each board operates as an independent synthesizer with its own effects processing and polyphony.

Studio Integration

The Motif Rack ES includes comprehensive Studio Connections support through Yamaha's Studio Manager software, enabling Total Recall functionality with compatible DAWs including Steinberg Cubase SX3, Nuendo 3, and Yamaha's SQ01 sequencer. This system allows the hardware to appear and function like a software plug-in within the DAW environment, with complete parameter automation and instant recall of all settings along with song data.

The included software bundle provides the Multi-part Editor for on-screen editing of multitimbral performances, though the Voice Editor requires separate download. The system is compatible with Windows XP and Mac OS X 10.3 or later, with USB MIDI drivers supporting Windows XP/2000 and PowerPC-based Macintosh systems.
