Hello, a fresh Octatrack user here 
So here’s my noob question on which i couldn’t find an answet from the manual.
Let’s say im in recording mode activating some individual drum sample trigs and tweaking them. I turn off one trig i have tweaked to see how the pattern sounds without that one trig, and when i turn it on again, all the tweaked settings are reseted to default. Is there an option for Octatrack to remember the tweaks even though the trig isn’t “on”?
Thx in advance
Copy trig.
Remove trig.
Paste it back.
Mute trigs would be nice though
Seems a little impractical… I’d like to tweak many trigs and turn them off & on on the fly
Agreed 100%
Well… octatrack doesnt work like that.
You could also try one shot trigs. And fill mode.
Oh, and scenes will also facilitate similar areas of tweakery.
Thanks, i will have a look at the fill mode
Think you can press trig + no and it will turn green trigless trig… press the trig to reactivate it…
I use it as a trig mute
This is great thanks !
Remember trigless trigs still trig lfos and filter envelopes. Read up on trig types in the manual.
There’s always many ways to reach any goal with OT.
You can press FUNC + the trig, which turns it into a one-shot trig (yellow) i.e. it will only sound once as the sequencer loops (I think), pressing the trig again turns it back into a normal (red) trig.
I have been using it as a trig mute, but seems like what @DanJamesAUS said would sometimes be even better (i.e. an immediate mute!)
If you hold a trig and press no twice it will turn into a trigless lock. Trigless locks do not trig fx envelopes and lfos. Turning them back into a sample trig needs a yes followed by pressing the trig once, so I usually just use trigless trigs like mentioned above (hold trig, press no - press trig to ‘reactivate’) for muting purposes. Just have to pay attention to how lfos and effects like filter and lofi are setup.
On midi tracks I set velocity to zero when I want to mute individual trigs. Hold trig and press the encoder to remove the zero velocity lock.
This of course makes the trig use the default velocity that is set for that midi track. So instead of removing the p-lock by pressing the encoder, it might be better to hold the trig and turn the encoder until you’ve set it to the correct velocity. Sounds complicated, but works actually pretty well.
No fill conditions work well when you have time to prepare the mutes. When you execute fill, all trigs that are set to no fill will be muted, so I don’t use no fill for ‘on the fly muting’.
Copy and pasting the whole track (as kind of quick restore) should do the trick, too.
Or just one page. 
FILL or /FILL would seem the closest thing.
I think you can even latch FILL mode, check TRIG CONDITIONS in the manual.
[Up]+[Down]+[Page] to latch fill mode, [Up]+[Page] to unlatch.
