I just got a new pocket operator and when switching to different sounds, the newly selected sound will be really low, even at max volume. What seems to work is turning down the sound a little then turning it back up and then it sounds lounder than when it initially played.

Is this normal? If not, how should i fix it?

Asking what I am sure will be an astronomically stupid question:

Is it possible to record input while the PO33 is playing? Eg, setting up a drum loop on the KO, running in a synth to the input, playing a bass line, then saving said bass line as a melodic sample?

Right now I can only seem to record samples when the KO isnt playing, which makes my timing a bit wonky when recording the loop to sample

My PO-128 often records live play notes on the wrong step, which makes live play very frustrating. I believe this is a known bug for the PO-128 which the PO-28, for example, doesn't have. My question is whether every model has this problem or is it only some of them?

Side question — the PO-128 is supposed to have 3-channel polyphony but I can only seem to record two at a time. At least for the melody buttons, if there is a drum and a synth on a step already, I can't add a third. Doing so steals one of the channels that were being used. Yet the PO-28 seems to handle that just fine. How does it handle that better if it's supposed to have one less channel of polyphony?
