What we think of the new Yamaha U1 TA2 TransAcoustic upright piano?

The new Yamaha U1TA2 builds on the success of the first generation TA model and brings with it a number of enhancements. Improved transducer technology means a better treble reproduction when in digital mode, while the improvements of SH2 make the Silent piano element better than ever before.

Much like the SH2 Silent piano, activate the centre pedal and a rail moves between the hammers and the strings, almost 'switching off' the acoustic piano. Where TA2 is unique is that a digital sample of the Yamaha CFX and Bosendorfer Imperial concert grands is then transmitted via specially configured transducers through the soundboard. This vibrates the soundboard and bridges to reproduce the digital sound, effectively turning the large wooden soundboard into a speaker. You can turn down the volume, layer other sounds (of which there are 20!) on top of the acoustic piano for added ambience or plug in some headphones to practice privately - the choice is yours!

The Yamaha CFX sample has Yamaha's acclaimed Binaural Sampling giving an incredibly 'acoustic' sound through headphones, like the piano is in front of you rather than right in your ears. Virtual Resonance Modelling technology borrowed from Yamaha's Clavinova range of digital pianos brings an unprecedented level of natural resonance making the digital sound virtually indistinguishable from the real thing.

With Bluetooth for audio streaming and compatibility with Yamaha Smart Pianist app along with many others, the new TransAcoustic TA2 system is a versatile tool which combines the best features of a digital piano with the inimitable resonance and feel of an acoustic instrument.
