Poly D : Very good and warm sound

Sound is rich and warm and gives lots of depth in performances, tone quality is beyond my expectations and love it as a musical instrument. All knobs fee nice and handling is excelent.

The build quality in general is good, but I feel the keyboard a little fragile and response of black keys do not exactly match the response of white keys. But I guess in general keys are ok provided you don't play with a heavy piano technique :-)

Output is a kind of low, if connected with usual line-level inputs gives something like -18db to -12db with volume at the full setting. With an active DI I get some good level, but you need double DI's to keep the stereo output (a very good stereo output from the integrated Chorus Unit). I also connected Poly-D to microphone inputs with very good results, output impedance of PolyD is about 1kΩ, so I guess it matches most microphone inputs.

Arpeggiator is very basic, but integrated sequencer has a lot of features and it is very handy, however is not well documented, but luckly there are a lot of tutorials in youtube.
