MHC released Ambient Keys for Windows (VST) back in November, the Mac OS X Audio Unit version is now ready and can be purchased for $99. A demo version is available.

Ambient Keys is a synthesizer, which plays an extensive set of ambient waveforms, processing these using a filter, envelopes, an LFO, an ensemble, delays and an effect section which features 133 different effect modes, including crossfading effects and layered effects.

Main features:

• 1024 presets, which are available in three soundpacks (included when purchasing the plug-in). A soundpack is an expansion which adds new ambient waveforms and a set of presets.
• Hundreds of ambient waveforms.
• Crossfading and layered effects involve distortion, filter banks, a resonator, flanger, sub oscillation, amp modulation, pitch shift etc.
• All knobs can be mapped to MIDI controllers with a simple "learn" function.
• Ensemble with adjustable amount and mix. Stereo delays.
• Full polyphony. Only your CPU sets the limit or you may set a fixed voice limit.
