This keyboard provides a lot more than expected. It's available for much less than the PSR S770 and PSR S970 and you get almost all the same features. Also, this keyboard is much lighter than the other two.

Let's dive deep into how good this keyboard actually is.

The Yamaha PSR S670 originally has 416 Voices (including Megavoices), 34 Drum/SFX kits and 480 XG Voices, along with Yamaha’s expansion module, so get ready to play all types of music - Indian, Chinese, Latin, English - and anything else you like! Besides this, it also has 230 styles including a brand new DJ category.

The voices and styles work nicely for providing accompaniment.

The keyboard has authentic voices and styles from all over the world that sound more real than they did in the Yamaha E series, which means there is definitely an improvement in quality.

From piano to electric music, the PSR S670 gives incredibly realistic voices. Moreover, the DSP system emulates powerful effects for a true, professional sound.

The diversity of the Yamaha PSR S670 is excellent. You can go from a harmonica to a classical guitar to a saxophone and grand piano. It all sounds amazing. You also have the ability to add more sounds through expansion packs.

The Yamaha PSR S670 also has powerful built-in speakers which provide a crisp sound.

Another important part of this keyboard is the polyphony, which is the number of notes that can produce sound at the same time. This includes accompaniments and other tracks that may sound while you play the keyboard. The PSR S670 has a polyphony of 128 notes, which is ideal as with 128 notes, you have a good polyphony without limitations.

The PSR S670 has 73 chorus types and 44 reverb types along with advanced arpeggios functions that help play difficult passages. This allows the user to record different sounds and then mix them during live performance.

Like the PSR S770 and PSR S970, the PSR S670 also comes with greater controls. It has a modulator and a synthesizer to assist DJs in creating and modifying the music played in real-time. These new features make the keyboard more versatile than other models. This keyboard gives you a chance to be a little creative and produce various effects using the live controls that are a wonderful addition to it.

In addition to this, the PSR S670 has multi-pad controls using which DJs can trigger playback of musical phrases, arpeggios and sound effects during a live performance. With this function, it is also possible to introduce your own live audio tracks whenever needed. Some other functions of this keyboard include recording and playback audio tracks, and crossfading between audio and MIDI playback.

Unlike other keyboards, this keyboard has an internal memory in which you can save audio tracks to play later. With this input function, you can create your own music from scratch and then plug in a computer to use it in your mixes.

It also has several metronome functions for transporting scales and an octave button as well. The Yamaha PSR S670 has a stereo line output which means you can easily connect the keyboard to any amplification system without an injection box, unlike the Yamaha E Series.

As far as the touch and pedals are concerned, the keyboard is equipped with several sensitivities but it doesn’t have hammer action. It has an input space for sustain pedal; however, the pedal is not included in the set. You can buy it separately. A sustain pedal doesn’t cost much but is a very important resource for a keyboard player as it helps you maintain a note.

With this keyboard, you get more than what you paid for. It offers almost the same features as PSR S770 and PSR S970 at a lower price point.

It can be said that this keyboard is inspired by Yamaha’s flagship product - the Tyros workstation. It is a good alternative for those who cannot afford the top-of-the-line PSR arrangers.

It has top-quality sounds along with USB ports and options to save music. You can create new sounds using the built-in sounds. Since it is an arranger with many built-in styles, It is also good for songwriting.

With the PSR S670, you get to experience what a good electronic keyboard sounds like. It has all the tools that you need for creating your own music. Although it is not very flexible in editing tracks, you can easily lay down the tracks on the sequencer.

All in all, the Yamaha PSR S670 is incredibly easy to configure and is one of the best keyboards available in the market, especially for entry-level players. It is a fully loaded arranger keyboard and at this price, it is definitely a steal!
