Was playing through headphones the other day and all of a sudden I got a lower volume echoy sound. I changed presets and same thing. After a bit of investigating found that the dry signal was not being output at all, only the fx blocks. If I bypassed these blocks there was no output. I tested again by creating a new preset with only the IN & Out block present and no output. Adding an Amp, Cab and reverb block I would get only the reverb sound and no dry signal. Bypassing the reverb block there was no output at all. I have 5.02 installed and have reset the parameter system but still the same thing. The unit was working fine for a couple of months with 5.02 and then this happened. The I/O and Global settings look normal. I did notice a few minutes before this happened that I all of a sudden got the red warning about CPU overload even though I did not change anything in the preset and preset was working fine before. Any ideas?
