The PSR-410 is a 5 octave keyboard arranger, I find it great because it's one of my first keyboard when I was learning. I bought this about 1 month for $ 50 euros in good condition. And yes at the time I sold to finance the purchase of E-86 ROLAND home.
It has the MIDI IN and OUT connectors, an input for a sustain pedal, a headphone or auxiliary batteries or electrical regulations.
128-10 sounds available harmony can be grafted on, 80 styles-8 drum kits, are enough at the time for fun.

UTILIZATION

Keyboard fairly easy to use, user manual required for certain parameters.
Rytmes sounds and can be accessed in seconds.
Clear instructions for use, no problems on their use.

OVERALL OPINION

I bought it exits at the time, 3 or 4 years then sold way together, since this new one month, I do not regret (nostalgia).
For 50 euros I cross that is reasonable.
This is a good arranger keyboard overall for beginners and those with a little practice.
