'realtime algorithm has been deactivated'

there are times when i slip-edit audio in the arrange window that a message appears on the screen for a short time :

realtime algorithm has been deactivated because pitch or or stretch factor lies outside the limits of the current preset.

i supposed that it would refer to some sort of audiowarp, but the message appears even when i slip-edit a clip that has no audiowarp modifications made to it.

what causes this ?
is there something i should be doing that i’m not ?


Is tha Audio event in the Musical Mode? Is any Time stretch applied?

Hi Martin,
Thanks for your reply.

No, there is no audiowarping on the clip, of any sort – time, or pitch. I don’t recall if it’s in musical mode, I will check tomorrow.

this is starting to get really SUPER annoying… the message appears on the screen whether the track is in musical mode or not. it will appear any time i do anything with an audio clip that i’ve subjected to warping – and that includes just moving the clip from one place to the next [i.e., don’t even have to be editing it]. and it KEEPS REAPPEARING, whether i’ve made new changes or not. the message has also popped up – bizarrely enough – even when i’ve edited MIDI tracks. HOW CAN I MAKE THIS GO AWAY ?? to be frank, i really don’t give a damn whether or not one of the clips conforms to some sort of preset, but i hate it when i’m getting up close and personal with a clip and this message appears ad nauseum, blocking my view ! :imp: :angry: :cry:

any help appreciated.

thanks !!!


Can anybody explain what’s going on here? I’m seeing this message all the time when warping also :frowning:

I may have a solution. Well, it has stopped with me and also the crashes seem to have stopped which were happening when I tried to open the wave form in the main editor as opposed to the lower zone editor. This actually started to crash when I opened the midi editor too. Both midi and wave were working in lower zone, just when I opened the full editor it crashed. Fingers crossed it has stopped.

I went into media pool ctrl + p then changed all audio event algorithms that were not Standard Solo to Standard Solo. Many of mine were set on Elastique - Time.

I hope it helps!

I’m getting this message as well in cubase 11
