Osiris Piano by Karoryfer

Osiris Piano is a quiet sample library of a Yamaha C2 piano, recorded played quietly with the soft pedal engaged and at half-stick. The goal was to avoid the problems with noise and inconsistent playability which affect many soft pianos. Key features:

• Three stereo mic positions.
• Separate sustain pedal up and down samples.
• Two velocity layers.
• Noise-reduced and natural versions of all samples.
• Half-pedaling implemented.
• Detune and layering controls.
• Natural and warm (transposed) patches.
• Over 1200 total samples adding up to 460 MB with FLAC compression.
