The Mayer EMI MD900 is a state-of-the-art, true stereophonic digital synthesizer featuring 16 stereo voices, designed for professional sound design, studio production, and advanced home setups.

Advanced Sound Architecture

With a layout optimised for intuitive usability, the MD900 harnesses the power of the XVA Sound Engine to deliver a sonic range that spans from crisp, high-frequency clarity to deep, resonant bass. Its virtual analogue design integrates modern digital enhancements, including stereo wavetable oscillators, dual stereo filters, stereo LFOs, and high-quality effects. Additional features such as an arpeggiator and an integrated drum computer provide further creative flexibility. The full stereo architecture ensures an immersive experience, making it capable of producing everything from rich pads and searing leads to thunderous low-end frequencies.

Ergonomic Design and Immediate Control

The MD900’s front panel is structured for efficiency, offering direct access to all essential parameters. Quick Navigation Buttons enable fast menu selection via the five-inch capacitive touchscreen, while the teach-in functionality allows for seamless modulation assignment. With 37 potentiometers, 12 linear sliders, 12 endless encoders, and 30 buttons, every function remains at the user’s fingertips, ensuring an optimised workflow and an elevated sound design experience.

Exceptional Build Quality

Precision-engineered and assembled in Austria, the MD900 boasts a robust aluminium chassis, accentuated with walnut wood front and rear panels. Every button, encoder, fader, and display is selected to meet rigorous quality standards, ensuring long-term reliability and a premium tactile experience. The synthesizer weighs 4.4 kg and measures 460mm x 295mm x 65mm, making it a solid yet compact unit for professional use.

Comprehensive Connectivity

The MD900 provides extensive connectivity options for seamless integration into any setup. The rear panel features a 12VDC power input, a power switch, and three USB-A ports. It includes sustain and expression pedal inputs, as well as full DIN MIDI In, Out, and Thru connectivity. Audio routing is flexible, with a stereo line input, two mono/stereo line outputs, and a dedicated headphone output, all operating at 24-bit/48kHz resolution. An optional USB-to-Ethernet adapter allows network integration, expanding its compatibility with modern studio environments.

Clip Launcher and MIDI Sequencing

The integrated Clip Launcher allows users to combine synth parts, drum instruments, and external MIDI controllers with precision. It facilitates instant switching between MIDI sequences and drum patterns, while additional tracks enable MIDI data transmission to external synthesizers. Synchronisation remains accurate, whether sequences are recorded from MIDI inputs, programmed manually, or loaded via MIDI files. Compatibility with external controllers such as the Novation Launchpad and AKAI APC mini II provides hands-on track control without relying on the touchscreen interface.

Arpeggiator and Sequencer

The arpeggiator transforms chords into intricate melodies with a variety of playback modes. Users can adjust articulations from staccatissimo to legato while assigning individual velocity values to refine dynamics. These configurations can be saved within presets, ensuring quick recall during live performances or studio sessions.

Integrated Drum Computer

A sample-based drum computer offers access to 14 configurable instruments. Each sample can be manipulated through start and end time adjustments, envelope shaping, and parameter fine-tuning. Drum patterns can be programmed within the grid-based sequencer or triggered live via MIDI controllers, providing versatility for both electronic music production and live performances.

Synth and Live Effects Processing

A fully integrated effects engine allows users to enhance sounds with reverb, delay, compression, and modulation effects. Each synth part includes an independent effect stack, supporting up to ten configurable effects per chain. The mixer section further extends functionality by processing external audio signals through live effects, effectively transforming the MD900 into a powerful performance-oriented sound processor.

Digital Mixing and Audio Routing

A digital audio mixer enables seamless control over all sound sources, whether from internal synth parts, drum instruments, or external audio inputs. Signals can be routed to dedicated outputs or processed through effect chains. Configurable mono and stereo input/output limiters ensure precise control over the final mix, preventing unwanted peaks and maintaining balance across the sound spectrum.

Comprehensive MIDI Integration

The MD900 aligns with the philosophy of fully integrated synthesizer workflows, supporting a range of MIDI communication protocols. It handles note on/off events, MIDI control messages, and clock synchronisation, ensuring seamless operation alongside DAWs and hardware instruments. Users can designate the MD900 as the MIDI clock master, enabling it to dictate timing across an entire setup.

Presets, Performances, and Variants

The digital nature of the MD900 ensures effortless sound preservation and recall. Users can store individual synth part presets or assemble complete performances, including drum patterns and layered sounds. A library of factory presets, drum kits, and performances provides immediate inspiration, with modifications saved as independent variants to maintain version control. The option to expand the synthesizer’s sonic palette via downloadable sample packs further enhances its flexibility.

A Complete Synthesis Solution

With its advanced sound engine, intuitive interface, high-quality construction, and extensive feature set, the MD900 is a powerhouse for synthesis, sequencing, and sound design. Its fusion of virtual analogue synthesis with modern digital enhancements ensures it meets the demands of both studio professionals and live performers, solidifying its place as a cutting-edge instrument in electronic music production.
