Any way to get the kemper delay to self oscillate?

What do you mean with feedback? Regarding the Kemper delays it's for dialing in the amount of repetitions and has nothing to do with a feedback produced by a guitar and a speaker at high volume.

He means the old tape effect that you can hear on records over the years where the repeat on the delay goes haywire and does self feedback. Not the guitar feeding back, the actual effect.

Even the end of EVH eruption has it except Eddie manually fades the effect out. You can hear the sound degrading every cycle before he fades it. The sound normally would never fade.
As the repeats start to freak out, they get more saturated and the sound gets steadily more lo fi and changes drastically.

Read about "Infinity" and other delay features in the Main Manual chapter "Delay".

It’s very easy to do with the infinity setting. I use that setting assigned to one of the I-IIII effect switches to engage it for the end of Eruption, for example (most people think it’s a whammy dive bomb, but actually it’s the Echoplex oscillating and Eddie adjusting the tape speed to take the pitch down a couple of octaves).

I don't how make infinity sound like this

. Every time I hit "infinity", delay is very very quiet compared to normal delay. Tried to change mix to post position, still I can't find any way adjust the delay volume in infinity. I just don't understand how to do the same thing as in that tutorial video, where infinity delay gets louder and louder.

Can someone explain to me how to do this? Maybe some preset?

Well, you just attached a video that explain how to do it with settings and %

so I don´t really understand your question .....

What OS are you running? Maybe these settings did not exist in older OS

like 5.0 or so .... I have no clue

Cheers !

The delay level is controlled my the Mix parameter. If this isn’t loud enough to start with the infinity delays will also be too quiet. However, to make the mix loud enough for the infinity effect you are trying to achieve you might find the regular delay is too loud. Therefore, I would try assigning the mix control to Morph pedal and ride the level of the infinite delay as required.

¨   Infinity

When you activate "Infinity”, another Action & Freeze function, Feedback will be switched from the regular value (between 0 and 100%) to the Infinity feedback value that spans from 100% to 200% and is separately controllable. This feedback lets the delay repeats build up instead of decaying – this pushes them deeper into tape saturation, where they will repeat indefinitely, as the sound degrades over time. To ensure a pleasing, lush result, you should adjust the sound of the tape saturation with the High Cut and Low Cut parameters. Set Mix Location to "Post” if you wish to control the signal level of the saturated delay by the Mix control.

In contrast to the Freeze function, Infinity Feedback still lets you add more signal to the delay, creating intermodulation with the repeated signal.

I have the same problem. My analog delay will run away but the kempers delay seems to duck when I play

please make sure the Delay's Ducking parameter reads exactly "<0.0>" even small amounts of ducking are noticeable
