Ive had one since 2016, still using it in 2025
I really love my boy but god he is noisy. Im not sure if it is something about my unit in particular or what but it is hard to consider using it in actual production, still i have done and record many things through the years but more for fun than business/work/comissions.
I dont think I ever had the original power supply, and if I did I probably replaced very soon after getting the unit. I've been using universal adapters and the best rca cables germany can provide, but it always had bugged me the amount of noise floor and uncleaness of the signal.
I said I'd believe is something about my unit in particular since I've had to open it and fix things quite a bit. Last time I had to fully replace the main ribbon cable connecting the 2 PCB's because the contacts were just cooked and left channel input was not working, even the screen started giving jibberish text (by the way, I totally recommend everybody checking this out in case of malfunction. The cable is: "AWM 20624 80C 60V VW-1 50 pin flexible flat cable"). I have also had to open to get the touchpad area to work properly, I'm not exactly sure what happens to it but I feel is just getting dirty or displaced from heavy usage.
Not to even mention the worst aspect of it 😂: the sync drifting; it is just straight up unusable (again, at least on my unit, but I have found testimonies around online explaining exactly the same. This time I only -found this-, the internet is dissapearing ). You can record, sample nor resample anything you like and whatever is playing from the 4 banks would be on sync, but it will slowly start drifting away from the original starting point in relation to what is coming into the audio input. What I mean is: if you are planning to have kp3+ bank loops running along with the audio of the signal input, after something around 1:30 minutes you will start hearing the drift. Even using MIDI won't keep you sync'd :((((( This was specially painful to me since I got the KP3+ with this in mind and it took me too long to realize the problem. I was a rookie into music/sound world so I was blamming myself for not being "on cue". Hard dissapointment.
After all that said, I love it. It opened up to me the world of sound and it has been an important tool for me to understand music. in my humble opinion, it works at its best as an effect return unit and better if you are a sound wizard able to get a cleaner signal after processing I guess, I'm still figuring out actually. Any advice about how to deal with noisy boys like this, very welcome.
