Description

Klavir is a deeply sampled Petrof upright piano built for the MNDALA 2 engine by MNTRA Instruments. It captures the warm, intimate character of a classic European upright using both modern ultrasonic microphones and a vintage figure-eight ribbon mic, giving each note a layered richness that blends darkness and brightness in equal measure.

The source recordings were made at an extraordinary 32-bit 384kHz ultrasonic resolution, then optimized for CPU-efficient playback at 24-bit 96kHz within the MNDALA 2 engine. This approach preserves harmonic detail that most sample libraries simply cannot capture.

Beyond straight piano tones, Klavir truly shines through MNDALA 2's sound-shaping architecture. The engine's 3-axis XYZ controller and six samplers let you morph the upright recordings into ambient pads, noisy drones, distorted synth-like sequences, and complex evolving soundscapes.

Fifteen presets ship with the instrument, spanning gentle acoustic pianos through to monolithic textural layers. The animated performance interface makes deep parameter control intuitive, with over 60 real-time parameters accessible through mouse hover interactions and MIDI-mappable 3-axis controls.

Klavir runs as a VST3 or AU plugin on Windows 10-11 (64-bit) and macOS 10.14+ including Apple Silicon. The MNDALA 2 engine itself is included at no cost, requiring only a registered MNTRA account and an internet connection for the initial download.

Frequently Asked Questions

Does Klavir require the MNDALA 2 engine to run?

Yes, Klavir is an instrument library that runs exclusively inside the MNDALA 2 engine. The engine itself is a standalone VST3/AU plugin that you download and install separately. It is completely included at no cost with any MNTRA instrument.

Does MNDALA 2 need a constant internet connection?

You need an internet connection and a registered MNTRA account to initially download and activate the instrument. After installation, MNDALA 2 and Klavir work fully offline in your DAW.

Can Klavir produce sounds beyond a standard piano?

Absolutely. While the source samples are from a Petrof upright piano, MNDALA 2's sound engine lets you sculpt them into ambient pads, noisy drones, distorted synth-like sequences, and complex evolving soundscapes. The 15 included presets demonstrate this range, going well beyond traditional piano territory.

How much disk space does Klavir need?

The installed instrument is 793 MB, but MNTRA recommends having 2.5 GB of free disk space available for the setup and extraction process. You will also need the MNDALA 2 engine installed beforehand.
