Hello. I have been a long time user of Sony products back to the Sonic Foundry days. I have been happy with the products, however I need some help with Acid Pro.
If I am to make any song keep a strict tempo, i would load it into acid then beatmap the whole clip/song. In the wizard, i would UNcheck "change project tempo with beatmapped track". Then i would proceed like how it is decribed in the help section - Beatmap Wizard>Fine-Tuning Beatmapped Clips. I would move the markers and drop anchors every 4 beats. I would try it maybe into a minute of the song then i would close the wizard and listen to the changes i made. it keeps a strict tempo alright but the problem is that on every anchor that i drop, a quick fade happens. Each start and end points of the segments with anchors get faded for a few milliseconds but enough to hear the effect. If I zoom into the waveform, a v-shaped fade is applied on every anchor location. Is there a setting that I am missing or is this a bug? i could not get rid of the quick fade and is driving me nuts. especially that it is very audible. Any help is appreciated. Thanks.

Maybe this:

Try Tools->Preferences->Audio and make sure "Quick Fade edit edges of audio events" is disabled (unchecked).

Thanks for replying. I unchecked that option but the quick fades are still there. i tried it on a new segment of a new song and they're still there. it only shows on segments where i dragged the orange markers around, even just a bit - but on the ones that i don't touch, no fades happen even if there are the dark brown markers placed on top of the orange ones.... i hope it was not designed to do that. could you, or anybody think of other things i can try? Thanks again.

BUMP... Hi. Has anybody noticed this behaviour? are there no workarounds to get rid of this momentary fade in/out? Help please... Thanks.

This is of no interest but I have seen those beatmarker fade lines on a variable tempo clip, but I never heard them have any effect. (I didn't manage to use variable tempo through the wizard - I did it manually in the clip properties by inserting beatmarkers.)

However I've just tried to figure out how or why, and I can't find them again.

So sorry - slightly directionless post, but just mentioned it in case it sparks an idea.

I am still having this issue. Maybe SonyPCH could try it and see if he gets the same thing on his system? The fades are not obvious - you will have to kinda zoom in to see it. it is acceptable on some material but on some with steady sustaining sounds, like violins or some synth sounds - it is heard - even if the fade is only for a few milliseconds. Please let me know if this is "normal" so i could stop trying to find things that might cure it. Thanks.

Try reducing the "Quick fade time" in the Audio tab of ACID's Preferences.

The "Quick fade edit edges of audio event" check box is only applicable on event edit, however the fade time value is also used around Beatmap (and project) tempo changes in order to reduce the possible audio artifacts that may result from changing the time stretch settings abruptly.

For sustained audio the quick fades themselves can be noticeable.

I'll also mention that the absolute placement of the Beatmap markers is not as important as their relative placement and another way of reducing the effect of the quick fades is to attempt to place the Beatmap markers in relatively quiet sections of the audio.
