Very good keyboard for the working musician

Zaferlamizik, 17.08.2015
The positive: 1) relatively light but can still take the pounding of real keyboard playing (especially piano and electric piano); 2) the sounds are of very good quality, especially with the freely available OS update and sound banks; 3) easy to create and save splits and layers in the very midst of a live performance (and controlling the relative volumes of those splits/layers); 4) ability to create and save slightly more complex programs for later use; 5) built solidly enough to withstand normal wear-and-tear during usage and travelling; 6) all that for what is one of the cheapest professional keyboards available.

The negative: 1) the sustain pedal that comes with this keyboard is slightly cheap as compared to a previous model of sustain pedal that Kurzweil used to make and sell separately; 2) some sounds don't seem equally balanced, but maybe it's by design; 3) some of the keys aren't equally balanced, for example I find it easier to reach maximum velocity on black keys than white ones.

Many other keyboards have all these features and more, and are proportionally heavier or more expensive. So, in my opinion, it is one of the best value-for-money lighter professional keyboards for the typical working musician. I have used it in professional recordings, live concerts and festivals, and typical gigs in bars, clubs, weddings, receptions, etc. and have been entirely satisfied. It is easy to set up and use.

I would recommend it for any typical working keyboardist out there who doesn't absolutely need a weighted-key feel, and who doesn't need a keyboard that provides artificial band accompaniment or the ability to play backing tracks, but who still wants good quality sounds and a keyboard that is easy to use.

Excellent keyboard and piano

I bought this because it offered a good set of compromises where needed, but didn't compromise on the quality of sound. You get 76 keys in a very compact unit - some keyboards are longer than necessary, or sacrifice too many keys. The weight at 11 Kg is heavier than a cased guitar, but is much lighter than many stage pianos. The sacrifice to achieve this is that the keys aren't fully weighted. However, they feel professional and have enough resistance. At this stage I have only used a few sounds, but the pianos are excellent, as are the bowed and pizzicato strings. The synth sounds are good - great portamento between notes, but perhaps outside my genre. I have only just started to look at splits and layering, which look promising. Cheaper multi-toned keyboards feel less classy and flimsy by comparison, and many of the other portable pianos are long and heavy. For a reasonable price the SP4-7 gives robust stage piano quality and voices I have been very happy to use for recording. Incidentally the Nord 73 Key bag fits great and has backpack type straps. If you want the full 88 keys with a weighted action, the next SP4-8 offers those.
