Expressive Synthesis for the 21st Century

Our Product Research Team

After 10 years of painstaking research, Expressive E has emerged with a voltaic blend of historic craftsmanship and cutting-edge technology to revolutionize your approach to keyboard synthesis. Osmose is a 49-key synthesizer whose highly versatile sound engine is fueled by the powerful EaganMatrix, a digital modular engine developed by Haken Audio. Over 500 diverse presets, dazzling onboard FX, and deep editing features barely scratch the surface. What makes the Osmose such a hallmark of synthesizer engineering, however, is its uncompromising approach to total polyphonic aftertouch, enabling three-dimensional control of each key across multiple axes. You can even apply these via comprehensive MIDI controls for MPE use with your DAW or device of choice, and Sweetwater’s synthesists couldn’t be more excited to take these compositional possibilities to their outer limits

Three dimensions of play

Unlike other forms MPE-capable keybeds, Osmose retains the standard action and feel of a conventional MIDI controller or keyboard. MPE — or, MIDI Polyphonic Expression — is a MIDI protocol that gives notes independent channels, making it possible to apply pitch bend, modulation, or other expressive control messages to each individual note. Each key has an extended range of motion from its usual resting point, allowing for continued expression through an assigned value. The same applies to each key’s Y-axis, allowing for additional per-note modulation whose range and target parameters can be modified with each patch and sound. Aftertouch sensitivity profiles and response curves can be customized for later use, with each of the advanced EganMatrix onboard sounds tailored for use with the unique expressive controls of the Osmose. Plus, the keyboard can be used as an MPE MIDI controller, armed with Multichannel MIDI that will take any sound to a new dimension of play, onboard or otherwise.

Sonic architecture from Haken Audio

Known for their early innovations in multichannel expression with their Continuum Fingerboard, Haken Audio were the perfect partners to bring three-dimensional aftertouch to a new generation of synthesizers. Expressive E’s partnership integrates Haken Audio’s innovative EaganMatrix into the unique workflow of Osmose’s flexible keybed, loaded with more than 500 presets out of the box with plenty of room to expand. The EaganMatrix digital modular engine perfectly manages the polyphonic aftertouch with each preset crafted to make full use of its unique expression curves and modulation parameters, covering over numerous categories of FM synthesis, physical modeling, and more.

Unbridled control

Osmose’s sleek, minimalistic aesthetics are a welcome contrast to its immense sonic prowess. Its controls comprise a handful of ergonomically designed and arranged backlit buttons and textured, clickable knobs. These orbit a vivid, full-color LCD screen, while pitch and modulation sliders are comfortably placed nearby. Its streamlined layout affords deep, uncompromising navigation and editing of each patch, including effects, keybed sensitivity, velocity curves, expressivity, and envelope/EQ values, all with plenty of room to save your presets for later. Osmose also has two ports for continuous pedal use, assignable to sustain or whatever synth parameter you choose, adding another dimension of expression through all 24 voices.

Deep integration

Armed with DIN MIDI in, out, and thru ports, Osmose is an extremely capable controller. Take its uncompromising, multidimensional control to your preferred DAW. Multichannel MIDI lets you explore your favorite sounds like never before. Two 1/4-inch TS pseudo-balanced line outputs handle full stereo playback, while a 1/4-inch TRS headphone jack is front-mounted for convenient solo play with its own volume adjustment. Thoughtful design includes a lockable connecter for the external power supply, too! While Osmose is an incredibly capable synth with a near-limitless depth of onboard control, the accompanying EaganMatrix editing software from Haken Audio allows you to dive even further into the uncharted depths of its unique synthesis architecture, creating and fine-tuning sounds to perfectly match your output.

  • ร้านเปิดเวลาไหนบ้าง?
  • ร้านเปิดทุกวัน เวลาทำการ 10.00 – 18.30 น.
  • ร้าน CT Music Shop ตั้งอยู่ที่ไหน?
  • ตั้งอยู่ในซอยเชื่อมระหว่างซอยสุขุมวิท 38 และ 40 สำหรับท่านที่มาเป็นครั้งแรกแนะนำให้มาจากทางซอยสุขุมวิท 38 เนื่องจากเดินทางได้สะดวกกว่า (ซอยสุขุมวิท 40 เป็นซอย one way ถ้าเลยอาจจะกลับรถลำบาก) โดยซอยสุขุมวิท 38 ตั้งอยู่ใต้สถานีรถไฟฟ้าทองหล่อพอดี สามารถลงจากรถไฟฟ้าทองหล่อ ออกทางออกที่ 4 ลงมาก็จะเจอกับซอยสุขุมวิท 38 ทันที ร้านตั้งอยู่ในซอยเข้ามาประมาณ 600 เมตร ก็จะเจอซอยเลี้ยวซ้ายซึ่งเป็นซอยเชื่อมกับซอยสุขุมวิท 40 (เป็นเลี้ยวซ้ายเดียวที่มีในซอย 38) เมื่อเลี้ยวซ้ายมาแล้วร้านจะอยู่ซ้ายมือทันทีเป็นตึกอาคารชุดสีน้ำตาลสองแถวหันหน้าเข้าหากัน (ร้านอยู่ฝั่งขวาครับ)
