This is a sampled reproduction of a Yamaha CF-3 grand piano from the early 90s. It was chromatically sampled, to maintain the tempered tuning.
Created by Mats Helgesson, 2003, originally in Gigasampler format, converted to flac for SFZ format by kinwie and published with the permission of the author on May 16, 2020 via e-mail.

The Giga file is 985 mb. Maestro Concert Grand contains 452 stereo samples. It was recorded with a pair of Neumann KM84 microphones in X/y stereo. x/y provides excellent mono compatibility.
The samples are sorted in 5 velocity layers, of which velocity 0-29 are piano, 30-59 are mezzo piano, 60-89 are mezzo forte, 90-108 are forte and 109-127 fortissimo.
Maestro Concert Grand is the second sample set with pedal up and down sounds separate from the key samples. It gives you, the artist, the choice of adding additional pedal noise in your recordings for added realism. They are located in a second patch, below the piano key range, at midi key number 12, 13, 14, 15, 16 and 17.
note: This is changed with Concert Grand v2, which has separate versions of the piano, and additional release samples in four velocities, adding 352 samples.
This SFZ Instrument is reconstructed with the heavily use of SFZ specification level 2.0 + ARIA Extensions. With this is mind, this instrument will only played properly in Plogue sforzando and similar sfz samplers that used ARIA Engine. Trying to play this instrument in other than ARIA-based sfz samplers may cause issues and problems if it doesn't support the opcodes superset used in this sfz instrument. If ARIA-based sfz sampler is not your choice, we advised you to choose a sfz sampler that has similar level of opcodes support for this instrument can be played and sounded as it should.
Pedals and Lid noises has been moved to Pedal CCs in this SFZ version.
Sustain pedal noise, at Sustain pedal CC64
Mid pedal noise, at Sostenuto pedal CC66
Lid noise, at Soft pedal CC67
Release : Release time for the sustain layers
Rel.Noise : Key-release noise volume
Ped.Noise : Pedals noise volume (all 3 pedals)
Veltrack : Dynamic range / velocity to volume response
This piano has the note-selfmasking sfz native feature and polyphony optimized. This means, when playing a lot of notes (e.g. repetitive, trills or sustain pedal down), the voices count will be handled effectively and lower, which also means less jumping in CPU usage and results in more natural piano sound behavior.
When not used, lowering the Rel.Noise and Ped.Noise to 0% also disabling those layers which means free up their polyphony usage and lowering voice count, so lesser CPU and RAM usage.
Setting Veltrack value to achieve a pleasant dynamic range that suit you also depend on your playing style and your keyboard/MIDI controller touch response. Try increase and decrease this "Veltrack" parameter as you play and feel the suitable one for you. To change the default value permanently, find this line in the sfz file : set_hdcc$VELTRACK=1 and change the value to the one that you wanted, range from 0 to 1.
MIDI CC numbers are assigned at the top of the sfz file with the #define macro. They can be quick and easily changed to your personal favor or to match your MIDI controller device setup. After loading the instrument in sforzando, click the "Open In Text Editor" blue button at the INFO page, the sfz file will open by your default text editor. You will see a list of parameter's defined numbers. Change the number to your preference and then save it (e.g. Ctrl+S in WinOS), the CC numbers are updated to new ones. This is a handy feature in sfz and is a bit similar to MIDI Learn function.
The velocity ranges can be adjusted directly also using "Open In Text Editor" button to match your taste or keyboard response. 5 velocity for sustain layers : #define $LOVELx / #define $HIVELx and 4 velocity for release noise layers : #define $REL_LOVELx / #define $REL_HIVELx
Try add a Mid-Side plugin after sforzando, and lowering the mid level to make this Maestro Piano more wider. Also increase some low frequency and decrease high-mid frequency, by adding an EQ plugin after sforzando can add warmth to the sound.
If you are an advanced user and well understand this SFZ format, you can also modify anything in this sfz instrument to your personal taste, make new presets and settings that suit to your private need. SFZ is an easy-to-learn format and very editable. However, if you use this sfz as your basis to create a new one and want to distribute it, we just ask to explicitly put a note that it's derived from this sfz instrument in this github repository.
Aug 23, 2020 : Cosmetic update.
Aug 18, 2020 : Renumbering polyphony group.
May 30, 2020 : Use release settings from original settings instead of curve definition which cause problem when sustain pedal involved. This issue was reported by Jeff Learman.
