Well Designed and Professional Keyboard. A Workstation Without the Sampler.

This is my first piece of hardware so there isn't a point of reference besides MIDI Keyboards and YouTube.

88-Key Hammer Action Keybed with Aftertouch and over 1,000 preset patches (think it was 1057?) 32-Bit Analogue Output DACs with sample rates up to 96Khz. 256 V.A.S.T Polyphony (or "normal" voices) , Kurzweil String Resonance, 6-op FM Engine, 2GB of Flash Play (ROM), and 2GB User Sample Memory. All of this on what appears to be a plastic frame. It comes with a bunch of knobs (including the defacto mod wheel and pitch slider) and other things that I'm too noob to take advantage of. Enough with specs and let's get busy.

The sounds on the keyboard are definitely respectable and it comes with numerous patches. Has good Pianos, E.Piano, Organ sounds, Strings, and respectable drum sets. As far as keyboards are concerned they're definitely good quality, especially strings, but it will not beat the sound of decent sample libraries. Not a pianist and don't use piano/key-based instruments often however Strings (violin family) are a different story. As far as keyboards go these are probably one of the better string ensemble sounds available. Even the mellotron strings are nice sounding. The orchestral brasses and woodwinds are more "standard" affair and don't stick out as much, though some are good. Many interesting samples but I do get the impression Yamaha has better acoustic instruments overall even if the strings aren't as good. That being said you can load your own samples via PC USB Transfer or offline on the USB Storage Port. Having this option allows you to work around any weakness you find on the board.

The keyboard is not GM Compatible though the drums line up pretty close. One tiny annoyance is that the bass patches are transposed down one octave. So exporting the MIDI the bass will be too high, inversely you import a normal bassline track it will be an octave too low, this is only applicable using any of the bass patches. Then there is the USB Feature. As a disclaimer you need to have the USB Drive in FAT32 for the PC4 to read it, most default formatted storage devices are FAT32 but I often format new drives and Windows will not format FAT32 if the drive is too large (more than 32GB?) To get around this I partitioned the USB Drive, one for the Kurzweil and the other partition for normal storage. The only purpose of the USB Drive is for offline transferring, everything has to be downloaded to the PC4's own memory.

To be quite frank I can't tell how much better the Forte is (strings seem higher quality) compared to the PC4. Maybe the Forte has a better key-bed, apparently it's heavier too. The PC4 also has additions unavailable on the Forte, higher polyphony (if you don't need KB3 which is free on Forte) and it all but obsoleted the Forte SE. After playing it I'm more satisfied with just using a MIDI Keyboard, VST Libraries, and writing in MIDI. It would be nice for them to release a 61-Key Version.
