It’s noisy but only if you use a long reverb, with a hiss on it’s tail… so either gate it on a mixer(I use a k-mix) or use a send on a mixer for external reverb instead (3p has only one stereo out)… There are different reverb types to chose from so you have a choice between noisy nice vs crap clean. I like the reverb, it’s lush, but it’s no way as complex as an TC M3000, eventide, empress, blue sky.
IMO: For drum sounds, really long reverb is not useful, for percussion like sounds i.e. pans, xylophone etc… they add a lot of character, and this becomes a weakness.
If your playing in a traditional band live and using the 3p as alternative/extra drums, you don’t hear the hiss above the other live instruments.
If you don’t need reverb, it’s not a problem - or you could just get a 2p, as the delay/reverb and external pads are the main difference… (if you can find one 2nd hand)
At the end of the day it makes percussion sounds, particularly the attack/velocity of the synth, like nothing else i know. A distinctive unique character, that I can recognize. (it also has really good pads)
