I've noticed two problems changing preset:
1) when I switch to/from a preset with the amplifier section OFF there is a very high peak of sound.
Here's an example:
(In case you ask, I use this type of presets for my acoustic guitar -Taylor with TES- that I like direct on the mixer, but I want to use the KPA just to add effects like delay, chorus and reverb.)
2) I found an old thread about noise changing presets, I thought it was solved, but switching presets while playing still has some little click... and sometimes some other click even after the switch.
Not always! Sometime the change is very smooth.
A couple of examples:
On the file above you can hear a little click on the second sound (almost at the end... just before the third sound) and between the third and the fourth.
On this file is almost in every change.
I recorded minutes of these and I'm posting the worst few seconds.... I know that it's not a big issue, but I think that it can be improved
