UTILIZATION

I use this keyboard pieces to learn (internal or download on the Internet via the USB port).
Lclairage keys are disabled by the pressure dun button, as it was possible to focus on the partition or lcran (although quil nShow quune time Each time, the treble right and left F clef).
Ltude the left lane (the synth voice soccupe right) shall be put into the press of study of voice left and vice versa.
Mode dtude dune voice, the synth has the courtesy dattendre you find the right key before playing lautre voice. In addition, the keys are not concerned disable which prevents losing the thread of Młoda with wrong notes.
If ever you are lost, a press of the button allows you to find dclairement notes expected.

OVERALL OPINION

The sound is trsraliste Portable Piano (except for phnomnes rsonance and dtouffoirs), it is sampled in Stereo. The others are of good quality but mono. The sound of the harpsichord not nest top, the flute and sax trs are correct.
The speakers are not great and made the headphone (brand) or a string of hi-fi (the quality is suprieur (especially the bass).
Lamplification is limited but sufficient to ltude.

This keyboard is almost perfect for learning-if mode dapprentissage YES 4 (standby mode on two votes while the rest of the synth soccupe orchestra) had t he implant ny would be nothing wrong (cf. YAMAHA PSR295).
Lillumination keys should, I think, be active only when lon is really lost. By trs effective against it is for those who want samus without learning.

Loading midi file via USB allows dtudier else those songs on offer, it is even possible to select the midi channel and therefore scores of dtudier nimporte what instrument.
