On our pianos, we use SuperNATURAL modelling to create the sound. This is a combination of samples and modelling. We sample every key of an acoustic piano separately at 4 different velocities (how hard the key is struck) in stereo, giving us 704 individual samples to work from. Here we can therefore see there is more resolution and more of the differences between keys of the acoustic piano are captured in the first place.
From there our modelling can recreate the complex interactions of component vibrations and pulses of the soundwaves which are created in the air when a piano key is struck. These will be different depending on how many strings are used per key (normally 2 or 3 depending on the pitch), whether the piano is overstrung (a fourth string), how far apart the keys and strings physically are, and how hard the keys are depressed. In real-time, our pianos recreate the harmonic changes which result from these differences, not to mention the construction of the piano, the density of the woods used, the construction of the keys, their hammers and felt on the edge of the hammer, the strings themselves and even the room environment. Individual keys should sound different.
For example, in a concert grand piano, there are hand-made components which cause minute differences in sounds when comparing individual keys. It’s because they are hand-made that the tolerances involved allow these changes. This is fully recreated in our sound. Play softly or with gusto and the character of the sound changes too.
Using the piano designer feature, individual keys can be re-tuned as desired, can be adjusted by volume and have an individual character applied. If any key appears ‘out of tune’ try performing a factory reset on your piano. If you still feel that you would like to attenuate the tuning, this can be achieved using the piano designer feature and saved into the piano for recall the next time the instrument is switched on.
Each of the different modelled pianos in a Roland piano, will sound different and have differing characteristic changes across the keyboard, as different acoustic pianos would too. This level of realism in the sound is unparalleled.
