This is what I wrote Sequential support. Does/Did anyone have/had problems with Take 5 humming? If so, what was the cause and how did you solve it?
"I got my Take 5 two days ago, and while I really love the sound and playability so far, I have a problem with a noticeably loud hum.
All my other synths (among them the OB-6 and the Prophet 6 as desktop versions) are connected via balanced cables for audio into a Presonus StudioLive Series III 32R and USB for MIDI, which works flawlessly without any excessive noise or hum.
When I connected the Take 5 for the first time with balanced cables, I noticed a distinct hum. Strangely, when I disconnected the USB cable, the hum got *louder*, so I tried unbalanced cables, which alleviated the problem. The hum was still there, but not as loud.
The problem is that the hum gets louder when I switch on other synths.
I have tried several different balanced and unbalanced cables, and another power outlet, but the hum stays the same (and independent from the main volume).
Via headphone on the Take 5, there is *no* hum!
It is important for me to know if this could be due to a faulty device, in which case I would send it back and replace it.
If not, I would be very grateful for any problem solutions."
