sample trak retrig clicks ?

[LO-]

can anybody retrigger a kick with out it clicking, i might have to try better drums , but i think mine is due for a reformat how do i do that to ?

[ritchrd]

hmm im gonna test it out..

yeah so with a 808 i got a click when i re trigered
but if i put the low pass on it the click goes away. but then you have to waste a whole effect just on removing the clicks

i also noticed that if i have the sample on trigger mode and i silence it before its done playing there is a click.

so maybe it has more to do with cutting off the sample prematurely?

at least you know its not specific 2 your machine

yo, i think it's some kind of interference, of overlapping. maybe
someone can try with batteries. it isnt the sample rate because when you move the kick to the SP606 and retriggers with no click, the same drum.

I notice in the 606 to avoid those clicks complelty , you have to zoom in and trim some of the start of the drum.

i remember using some drums on the sequencer with retrigger and they didnt click, my sampletrack just started clicking not to long ago. i thought it was poor sample sources, but my fruity loops clicks and pops most of the time now too. :?

ill run some more tests and post here.

808 clicks are common in sampling without 'ramping' because of the clean sinewave cutting itself off with a new sinewave.

Hope this picture I drew explains it well for you.

Dope drawing +1
this makes a lot of sense

To another degree, if you have a DC offset on a sample that's not a clean, smooth sine, you'll also get clicks because of how AC works.

Basically, in AC, you start in that center line when you trigger a new sample. If you have DC offset, you 'jump' back down to 0 to start the sample again and the entire thing is shifted either up or down from the center line so that either positive or negative peaks are not symetrical. For every peak, there should be a near equal negative valley on the wave, theoretically, with most sounds. So to jump back to 0 then jump back up or down to the offset creates a click. So if you ever see "DC OFFSET FIX" or "REMOVE DC OFFSET" option in your programs, you should use it. There's different algorithms to remove it. The best ones check adjacent peaks and valleys and do this for each peak/valley pair. Some just take the average of where peaks/valleys fall and shift the entire wave down to compensate. Both are better than nothing, but the former method is preferred and allows you normalize your wave to be louder since DC offset also kicks up your VU meters without any evidence of the sound being louder.

cool man had no idea about that , you explained it well, i still have some questions but and not knowledgable in these subjects well .

is the AC/DC a power situation or audio schema like dither or sample rate, or a mechanical situation like power conditioning or bad house wiring.

will the 'DC offset fix' take the clicks out of the recording or prevent the click distortion when rendering ?

I thought the memory was flaking out or something, or not shure why is does that, what is the point of retrigger when it clicks all over the place.

yo, hseiken , what kind of phenominon is that when a whole recording manages to be completly on one side of the pole ? the middle line, I saw that before it looks cool and has a curious sound to it, ill try and dig up a wave form to help show what im talking about. . cool

Sample only in hifi mode on the 224 to get rid of the clicks.

cool, ill try it in the hifi, i wonder if theres a way to limit the retrigger polyphony so it doesnt overlap.

Also, if ever editing on DAW or 505 with wav form view always good to try and slice at "zero point" crossings. Directly related to the drawing above-
http://en.wikipedia.org/wiki/Zero_crossing

You want the wave to keep going in same direction- if left cut is heading down towards zero then you would prefer to have the right cut continue from zero moving down.

Using your ears is fastest and easiest but good info in this thread!

amazingly enough, the 606 doesn't click with a bad zero crossing, it's amazing! i'll have to examine a wave and see,

you have to usuallly just watch out for that (voltage shift?)

from sampling between machines, sometimes at the end of the sample.


my 404 og handled zero crossing really well too, i think pretty much only youtube videos sampled loud would detect bad zero crossing marks.

I remember when ACM wave sounded rich and crunchy now, everything sounds weird.
