Not sure if this is normal behaviour or a bug, but it seems that a static sample slot linked to a static machine won’t play when there’s trigless lock set in the pattern
i recorded a video for for demonstration. first without a trigless lock - static machine plays.
then i create a trigless lock (sample trig + 2x no) - static machine won’t play
is this the normal behaviour of lock trigs & manually starting a track?
so… i guess it is a (known?) bug. 
Not very demonstrative video audio wise. I can’t see the play icon on my smarphone.
Depends on your AMP settings.
These aren’t trigs but stickers. 
set trigless lock on step 1,
set static sample, quantized trig: pattern length, set pattern mastern length: 16
press play
while the sequencer is playing, hold track button and press play - the sample won‘t play
do the same as above but instead on step 1, set the trigless lock between step 2 and 16 - the sample plays.
0 attack
inf hold
0 release
the sample plays by putting a trigless lock on step1 and step16 
Probably the culprit.
Can’t test atm.
Are there AMP plocks on your trigless ?
same result with inf release
no plocks, but tried with some plocks as well. same result…
well, this happens only when synced to an external clock. after removing the tick on „clock receive“ in midi settings the same behaviour occurs - sample doesnt play
So you mean it happens only you send clock to OT, even with Clock Receive Off ?
(A bit more complicated to test…)
the sample plays when:
trigless trigs are set on step1 AND Step16 AND external clock is connected to OT AND OT syncs to it.
the sample does not play when:
i unplug midi in (external clock) from ot (or deactivate clock receive) AND/OR when trigless trig is set on step 1
So @marccc I think I can confirm the bug, a PLEN quantized sample (Flex or Static), isn’t triggered if there is a trigless on the first step (corresponding to PLEN timing).
Same occurs if Quantized timing corresponds to the step with a trigless (ex trigless on steps 1 5 9 13 with Quantize = 4/16).
A workaround is to use microtiming (+1/384). I think you mentioned it, can’t find it anymore…
Same with Trigless Locks.
thank you! so i guess it would be good to send it to the elektron team? or will no more bug fixing be done for the OT?
Yes. But I really doubt it would be a priority. I think there are a few workarounds. Microtiming, maybe Plays Free tracks with 1ST trig condition, Neighbor track…
I guess you want to play a long file and modulate it with sequencer’s trigless in a smaller loop ?
I hope there will…
