Hi, I'm not doing anything fancy, and this problem just started happening today. Here is my signal chain:
guitar > Kemper > main out with XLR to Alesis iO2 (usb) interface XLR in > iMac > out to KRK Rokit speakers.
Today, I noticed sound was only coming from one speaker. I checked all cables, even tried playing a song from iTunes and it worked fine through both (so it's not the imac or Alesis). But playing through the Kemper sound only goes to the left speaker. I switched the mains outs to the other output to see if it would make the sound come out of the other speaker but it did not do that, it still only comes out of the left speaker. I don't see any options that would make sound go to only one speaker. If there are, I haven't touched any of those. This happens on profiles I've been using where this issue did not occur.
Does anyone have any ideas?
