Be aware that this is a 'semi weighted' keyboard and does not have full size piano keys... piano keys are a little longer, these are synth style keys and more suited to a keyboard player, not a classical pianist (but they do have some weight to them).
I think that anyone who has researched keyboards of this kind will already be aware of this.
I purchased it for two reasons. 1) to improve my piano playing and 2) as a MIDI controller for my DAW.
It is not a full featured MIDI controller but does what I need to do and I have the full range of 88 keys available, which is great.
As a stand alone piano/keyboard it is also great for what I need. I may purchase a full size, fully weighted board in the future, very possibly a Studiologic SL 88 Grand. Studiologic recently upgraded and added some new sounds to the Numa Compact and they are fantastic… and Studiologic were great to deal with via e mail!
Be aware that the speakers are better than many reviewers make out. Most boards of this kind do not have speakers at all and I think that having them is a big plus. If you just want to practice a little, you don’t have to fire up the computer or plug into an amp.
I say again… I love my Numa! And it’s soooo light and portable.
