Random click on Drum 1 bassdrum

Hi all!

Super happy with my LXR, but I seem to have a weird random click on drum sound 1.

It is on the kick, not between steps or random in that way, it sounds more like an accent click of some kind.

I've  tried to attach a audio file, but no go.... instead -> https://dl.dropboxusercontent.com/u/19048733/LXR DB click.wav

    I can confirm that this click sound has haunted me at times. I'll try with your settings and see if it's 100% reproducible here.

    Is there a click hardcoded into the kick drum voices? I always have to dial down the attack in the AEG in order to avoid a click sound. Not sure if this is the same click sound that we are debugging here, but it would be nice to be able to turn off any hardcoded clicks.

    normally no hardwired click.
    in fact voices 1 to 3 use the ecaxt same code.

    I've noticed this as well. If it's happening, it seems to change or go away if the tempo is modified slightly.

    Are the oscillators synced every new beat or are they freeruning? If they are freerunning it's not strange that there is a click sometimes because the attack sometimes happens at the 'top' of the wave. Setting your attack to 1 instead of 0 should solve the problem...

    I'll have a look on the scope.

    I can confirmthe click and I found out it seems to be related to the filter.
    If you turn the filter off, the attack sounds always the same.

    Now I got to find out why the filter is altering the attack phase of the sound...

    Great! Glad to hear it has been identified. It always felt strange, but it was on all the BD voices so I figured it was intended. Also the tempo-change suggestion didn't work for me, so I was beginning to fear it was something wrong with my specific unit.

    i have also this click, but differently, sometimes, i have a click added on pattern i did a day before, and it's added, really strange !
  • julianjulian
    what I don't get about it is why it is tempo dependent.
    If I look at the waveform recordings, the filter seems to invert the transient of the sound sometimes. But It really depends a lot on when a note is triggered.

    I even tried optimizing the synth routine function call order, to be sure it's not the order of calculations. Had no effekt at all. At the moment I'm tending to a numerical problem in the filter code (something that oversampling probably could solve, but I doubt theres enough processing power left...

    so either I have a great idea to improve the current filter modell (maybe I have to do some propper simulations using the desktop PC) or provide an alternative 'clickless' filter modell. This was my first approach on calculating a 0df filter, so I'm sure it still could be improved.

    sadly not one of those quick fixes :-(

    I've noticed a "random click" which may be this thing, or it may be a different thing.

    What I have noticed is a glitchy click that can happen on one voice, which is related to notes being played on other voices.  I don't have all of the rules figured out yet, but I was trying to find out why a certain beat of my kick drum had a glitching attack when all other hits did not... and it didn't happen when I soloed the kick track.  As soon as I un-muted another track (I think it was clap/snare), the kick drum had a glitch again, on the beat where both kick and other-track were playing on the same step.  Seemed very repeatable.

    Last time I checked I was not getting consistent sound out of my kick drums, and this click was very much there. Haven't ever gotten a response as to whether the "fix to zero crossing" addresses this issue or whether we are still waiting on a solution?

    After an update to 0.34 I also noticed a click I don't think I ever heard before. At first I thought it was something in the updated firmware, but when I tested previous firmwares only going back to 0.27 made an audible difference.

    When changing the attack from 0 to 1 the click is gone in most cases, so maybe it's just due to a snappy attack. I tried to upload sound examples, but that wasn't possible, so could anyone try the patch I uploaded on the forum and confirm the click? Maybe it's something in the patch.  http://forum.sonic-potions.com/discussion/28/all-your-presets-are-belong-to-us#Item_17
    I'll do dome more testing tomorrow....
  • julianjulian
    so this is another click than the LP filter problem? does it also occur with the filter turned off?

    I finally had time to do some testing......

    Turning the filter off has no influence on the clicking sound. It occurs only on the first three drumtracks, and it seems to be kind of random. As stated before, setting the attack to 1 solves the problem most of the time, except when two notes are triggered fast after each other.

    I'm not sure why I never noticed this before..... :-<
