Audio Pop with Module12

[jgriff]

Hey guys, have another annoying question that hopefully someone can answer...

I've been using the Module12 Instrument to do my drum triggering. Problem is, is that at the end of every sampled being played there is a subtle "pop" at the end. Its very similar to that of a sound file being cut in the middle of a segment.

I've tried changing the pitch, cut-off area, time-stretching, gates/limiters...you name it. I can't even find it in a eq.

Any suggestions or a point in the right direction would help, and thanks again.

Try raising your buffer setting to 1024 and see if that makes a difference. I would get clicks and pops on my old G4 when I had my buffer set anywhere below 512. Not a problem anymore on my Intel Mac.

Hmm, changing the buffer size worked to solve some of my other problems, but I can still hear the pop come through the mix. It really sounds like the drum samples are ending early (even thought I've tweaked the duration on them). Any more ideas?

I don't think it's a buffer issue. I think whoever did the sample editing on the Model 12 sounds, left a few clicks at the end of samples by not editing to a zero crossing - mostly on kick drum sounds. Although I found by just adjusting the release of the sample I could get it to fade off before the click and therefore get rid of it.

It sounds like you've already tried that and it's still not working for you.

Could you list some of the offending samples?

[jgriff]

To be honest, I hear it in all of them. I thought it might be speakers, but its in my headphones too. Also, no matter where I place the cutoff I can hear it, leading me to think that it could be something to do what my actual settings are...which is 96k sample rate and 24 bit. I'm on a intel-based iMac with 2 gigs of ram. You can't hear it when the drums are in a mix, but man does it suck when there dry!

EDIT: Its my interface. It pops whenever sound stops coming through the firewire! That is kind of lame to me, do you guys usually route output through your interfaces?

What interface are you using?

[jgriff]

One that was recommended to my by a friend. Its a Phonic Helix 18 firewire interface. I haven't had any problems with it and all the user reviews I've read are pretty positive, other than that I don't know though.

Try 44.1k Sample Rate. Unless you are doing pristine acoustic recordings with top quality gear, I suggest you are, best case, simply wasting CPU cycles working at 96k and, worst case, degrading the sound of your VIs. Most VI samples are recorded at 44.1k. DP is probably sample rate converting the drum sounds on the fly; this may explain your problems. Please let us know your results.

[jgriff]

That seems to have worked. It also saved a ton on CPU load, though I'd like to record at 96k. Thanks again guys for the help, I really do appreciate it.

Oh, here is the song I'm working on if you guys want to check it out, its an electronic cover of "Georgy Porgy" by Toto-

[Mr_Clifford]

If you're doing mostly electronic music then 96k isn't going to help you much because most the VI's (and pretty much all hardware synths and samplers) all run from 44.1k (or 48k) samples.

The biggest advantage to recording at 96k is things like live orchestras and ensembles, particularly string sections, which have complicated polyphonic waveforms and lots of high overtones.

Anyway, best of luck with your stuff. Have you heard Andy McKee's version of Africa on YouTube?

[jgriff]

Wow, that video is pretty crazy! The only the thing I could find even wrong is sometimes it goes out of tune, but other than that its simply amazing.

Yeah, I just was now being told/thinking about samples being the typical 44.1/16bit rate. Which makes since, just wanted to try and flex what little DAW muscle I have!
