    Cant sure I can help but can you explain your setup please? WHich soundcard,what's connected etcetc.

    ok my st up is:
    PC intel core 2 duo 2.3 GH, 4G of RAM, soundcard tascam us122. ableton live 9 suite/ with evolution mk 249 (keyboard) and QuNeo (pads)
    Shruti1/ takamine/sm58/LXR to a mackie 1402 vlz3 direct in tascam us 122
    that's it

    Where are the clicks, pops or noises coming from? From the PC (Tascam) or from the LXR? You can try to disconnect the Mackie mixer from the Tascam audio interface. And then try with headphones or monitors directly connected to the Mackie. Can you still hear the clicks then?

    gonna try this ....

    Ho sh** I just found that the click and pops in my lxr recording didn't came from my bad soundcard but from the usb! So i have the same problem here, when I play a sequence with and without usb connected, there is a huge difference. Absolutly no click without the USB. It's funny because the click does not appear suddently/randomly, if I play the roll i hear some pattern of click, like they are related to the sequencer :). Anyone can confirm this too?
    So, two ways i came accros to avoid click. i to raise the buffer size of the sound card and record 1 track by 1 and not all together. I get some click like one every two bars but i cant cut it or manage it with enveloppes in ableton.

    REally funny because i didn't have click when i was using ableton usb and lxr before. The LXR was just plug directly in my monitors.
    Did you try to use MIDI thru the soundcard instead of the usb?
  • WhiteherbmanWhiteherbman
    yes with midi and without usb, absolutely no problem. since i plug usb and ableton ,there are some clicks and pops. when ableton is off and usb is plugged, there are no clicks, but when i turn ableton live on , noises and clicks appears.

    Yeah absolutely same here,ANYONE CAN CONFIRM THIS?? Did the buffer size changes anything for you? I still have lots of pops but less than with a high buffer size.

    Sounds like a MIDI loop issue, maybe.  Do you have both USB and MIDI DIN connected?
  • WhiteherbmanWhiteherbman
    yes both are plugged...
  • mmarshmmarsh
    unplug one and see if this persists, but i think this is your issue, maybe
  • erwanoneerwanone
    WHat are the causes of a loop issues?
  • mmarshmmarsh
    You are sending duplicate MIDI commands to the LXR. It's confused.
  • WhiteherbmanWhiteherbman
    i unplugged midi and problem is still here.

    I heard less click but backnoise if i use only usb on my new soundcard... Nothing if only midi, really clicky with usb and midi... Maybe you can try with others setup (other pc, soundcard of friend etc) to exclude any setup issue.

    ok thx erwanone

  • julianjulian
    could you try this version and tell me if the crack/pop is gone?

    http://www.sonic-potions.com/public/FIRMWARE.BIN
    or
    https://github.com/SonicPotions/LXR/raw/master/firmware image/FIRMWARE.BIN

    I want to be sure before I make an official announcement.

    Also, are there any OSX users here that had problems with MIDI clock sync over USB?
    May be fixed as well (but I can not test it myself)
  • erwanoneerwanone
    I just try and heard no clicks /pop with the new version. I take record before with usb/midi of a 4/4 kick pattern and get some  clicks/pop every 10 kick maybe and no more after the update! i need to explore more later but after 10 minutes absolutly no clicks thanks!!!
  • WhiteherbmanWhiteherbman
    great! hope it will be the same for me!
