regarding your non starting sequencer-are you sure your midi io on the lxr is working? can you play instruments using a midi keyboard? or do you have some midi monitor software like 'midi ox' to makesure the LXR is sending something?
at the moment i don't have a connection to my computer since i am trying to avoid it generally i tried other things as well, just to be sure its not the other component. but the x0x does trigger the elektron and the elektron triggers the x0x.
ok, tried midi-ox and it doesnt receive nor is it able to send sync from/to the lxr
wait, another test after restart and now when i hit play in midi-ox, the lxr starts and immediately stops playing. as soon as i unplug the audio outs, it starts synced by midi-ox. just like with the other hardware. seems it definately has to do with those audio-outs (how this ever can be, i dont understand)
could you check for a short between pins 37 to 40 on P2 (the mainboard connector faced to the potentiometer side). they are labeled "midi in, midi out, adc14, adc0"
both adc pins are connected to the switches in the audio jacks, to recognize if a plug is inserted into the jack. both midi pins are right next to them.
it seems that there is a short between adc0 and adc14. but not between any of them against midi in or out... what to do now?
ok, i soldered here an there, just where it looked like there could jump some electrons. still no success.
however, i went back to 0.21 and now under whatever circumstances it sometimes starts playing when i start the a4. i'll go up to 0.23 and see what happens. seems a bit unreliable at the moment. sometimes it starts sometimes not
the short is normal aslong as no plug is inserted into jack 1+2. then both pins are tied to aGND. I assume only out 1+2 are affecting midi? not out 3+4?
could you maybe post a closeup picture of the solder joints for those pins? how did you measure for a short?
additional info: when i power up the lxr and the midi in is plugged, syncing doesnt work. if i power up with no midi in and attach midi cable after startup, it seems to work every second start. dunno
gone up to 0.23 and now it sometimes sync and sometimes not. the audio ports dont affect it anymore, so maybe the oversoldering helped on that.
anyhow, directly after powering up my hardware (i have one main switch for all) it doesnt work directly. i need to change bpm up and down to zero. press play sometimes and then it starts (if lucky) could it be that there is some midi data which goes in on startup and confuses the lxr?
It may be due to the sync bug I found today. When midi clock signals where received after booting and before pressing play the LXR can freeze. I try to upload a fix in the next half hour (son did not want to sleep today, but is now finally in bed), maybe this will solve your problem.

I am experiencing this also - sync rarely works automatically by setting BPM to zero - when it did work it usually needed a few repeat changes of the BPM down to zero and hitting the play + stop buttons a few times.
Thinking it might be the midi port solder as the port appeared to be a bit loose and possibly have a bad connection, I have just removed the LCD which was awkward, but the midi port looks well soldered. I'll put it back together but wanted to check if unreliability with sync has already been fixed in the sampling beta? (I also had the problem with the latest release firmware.)
my solution is not to put the top left little black screw to hard. as soon as i screw it to the max sync is gone. when i have it a bit loose it works... thats how i am having fun with my lxr. and i can tell you, i am having a lot of fun http://www.reverbnation.com/play_now/18842332

I might try either putting some supports beneath the lcd card or better might be cutting a hole in the plexiglass to prevent it from getting pressed down. The case seems to push the LCD down causing this midi error. Too much pressing the lcd starts to mess up the text, so I guess is interfering with the lcd boards pins. I tried putting some thin cardboard beneath the lcd card, in case there were shorts, but that didn't help so I guess it isn't a short between the lcd card circuits and solder on the board beneath ...
With no front panel on, I can only boot while pressing the bottom edge of the lcd panel downwards, sync will only work when i release the pressure on the lcd. However then my lcd text is corrupted when i try some menus.
if i keep the pressure on the lcd, then i can use the lxr fine, but midi in doesn't work.
I might have to detach the lcd again and try resolder all the pins afresh.
Yup, take a look in the manual. In one of the last firmwares the filtering of MIDI has been altered heavily. And MIDI channels are now assignable to voices and/or global.
I've very annoying timing problems syncing with ableton. At the moment i'm only using the lxr via midi/usb to sequence my drumracks in ableton. I've adjusted the internal latency over and over. sometimes it work fine for a little moment, but then it starts to get off the grid. i've tried master/slave changes in both ways. but the lxr isnt able to get a tight "1" to ableton when i want to record a clip. bpm ist set to "0" and txf/rxf is set to all in slave-mode.

try if this version works.
if not, just for clarification
MIDI in general was working.
you only had problems with midi sync?
or was MIDI completely dead?
all other situations work stable
I noticed I also need to press play and set the bpm to '0' on the LXR to sync it with my DAW as mentioned by other users.
More importantly, the play/pause buttons in my sequencer seem to have no effect on the machine.
I'm using FL Studio and the latest firmware (0.24).
And MIDI channels are now assignable to voices and/or global.
bpm ist set to "0" and txf/rxf is set to all in slave-mode.
any suggestions?
