I didn't like the on board speakers in the P-125. The 121 sounds so much better. I sold the 125 and sorry I didn't get the 121 (which is cheaper). Good luck
Hi Zuki,
didn’t realise there would be a difference, I thought they’d be the same except for the number of keys. I was tossing up between the two, ( had to buy sight unseen), so I was hoping I would like the sound, (which fortunately I do) . I also use some piano vst’s with mine, just for a bit of variety.
