Good when hitting pads, sounds like slight bitcrush playing

Sounds weird I know. I've taken 909 kicks and shortened them in the ENV:AMP section and it sounds good when hitting the pads. But when playing a track, there's a slight zipper or bitcrush noise during the decay of the AHDS envelope. With hold of 0% and 60 decay, the kick has the noise the entire kick. hold of 10% or more and you can hear clear kick then the noise as the decay starts. 60 is a long decay so its not cutting the sound of too quickly. Any ideas?

Found it. Its samples I made myself from a TR-8. I don't know why it makes a noise only while playing but if I substitute the samples for another set (Goldbaby!) it works fine.

Are you running any dynamic plugins, such as compression, limiter, maximiser etc? The noise could be there in the original sample but not particularly audible, however, depending on the settings, the compression will amplify the noise as it is effectively raising the level of quieter portions of the sample (while reducing levels of any peaks). Hence the existing noise becomes disproportionally louder.

Does it happen when you reopen the project? I have experienced this, but it went away when i reopened the project - super weird and i still can't pin point what triggers it.

Sorry about the timezone delay. No fx on anything. I can create a new project, add that kick, shorten the amp env, lower the LP2 filter and it does it. Sounds fine when hitting the pads, makes a noise when playing the kick in a track. The noise is one thing, but it only happening in play is strange.

Yes, happens when I reopen it. Do you agree its the decay phase of the AMP env?

I think the problem could be more easily solved if you share the sample and program...

Does this download link work? Just a project with my sample. Hit Pad 1 to hear the kick, then press play and hear the noise on it. Its there in headphones.

The problem can be reproduced on my MPC One. It seems to depend on the number of samples or channels in a pad.

1. Place the stereo(original) 808 sample on layer 1 of the pad = With noise

2. Place the mono(stereo>mono) 808 sample on layer 1 of the pad = Without noise

3. Place the mono 808 sample on layer 1 and silenced sample on layer 2 = With noise

Well spotted! easily avoided but weird bug.

Amp Envelope, DECAY = 56
Filter Envelope, LOW2, CUTOFF = 46

They aren’t playing nice with each other.

Why, stereo phasing in your sample. Elijah just pointed that out.
Convert that sample to mono.

My point is it doesn't happen when hitting the pads, only when playing back tracks. Its a bug otherwise it would do it hitting the pads as well. The filter is not related although the low cutoff makes the sound more obvious (and I like how it sounds).

Could playback be at a higher velocity than you are achieving when hitting the pads manually?

Try his sample file. The sound from the sequence/external-midi is different from hitting the pads even if the velocity is the same.
