It’s been a few times i’m stuck with this: i’d like a track to fade in when it comes into the arrangement.
Let’s say track 4 is muted for the first 2 rows of 128 steps each. Then it fades in and reaches its peak volume after 64 steps.
How would you set this to use it with the arranger? I guess like a one shot slide trig or LFO with some trig condition…
It is the typical case where i hate the OT and its calculations from the deepest of my heart. On a DAW a fade in would take 2 sec…
LFO designer, target set to amp vol, ramp from -64 to zero. Set rate to 1 and speed to 16 (I think)
Or resample your track, use AED to highlight whole waveform, go to edit tab, select fade in.
Thanks for your help.
So I need to use the LFO designer, i can’t use the Ramp waveshape?
Any idea about the condition trig to use? I guess even when it is mute the track count doesn’t start when it is unmute by the arranger.
Or maybe i need to use a pattern without a trig and another with a trig and the LFO you mentioned. Or a slide trig.
I won’t use the resampling, i already use the 4 parts. I could use a P-lock but i also would like to get to know how to do with the LFO for a next time. I’m working sometimes for theater/circus stuff and i need this trick.
Hmm, you could use ramp, but you need to check depth setting as I can’t remember if it is bipolar or just positive.
For triggering it I’d use first condition, and a copy of the pattern with the LFO depth locked to the volume just for the pattern where you want the fade.
Ok thanks again, i’ll try this as soon as i’m in front of the OT.
Yeah experiment is the way to go, once you get the volume change working, adjusting rate, speed and depth to dial it in exactly how you want it.
Indeed experimenting is the key but when you have to cut your workflow to dedicate one hour to experiment and solve a volume ramp, it’s frustrating and not very productive 
Just remember write it down, in case you need it in the future
Ramp LFO is bipolar
To get a 0-127 modulation:
LFO Depth - 64
Modulated parameter - 64
I mostly work with master pattern length of 128 steps, LFO speed 16 & multi x1 make a perfect ramp for 128 step pattern
Hope this helps
Would a slide trig be an option in this case?
I actually don’t think so. In this case i have only one trig in the whole pattern and slide trigs modulate between 2 trigs and their values.
OK 
I am actually only 3 months with OT so it was a genuine question.
Thanks for clarification, that adds to my little knowledge (or confusion) to this beast.
You can set vol to zero on first step, then put a trigless or lock trig on the last step of the pattern with the vol to 64, then use slide trigs. But be aware that any other plocks will be slid too.
Note, you could also do the above, but put another sample trig on step 2 then microtime it fully to the left, so that essentially it starts at the same point as the first trig. If you set the first trig condition as first, and you last trig as first, and your microtimed 2nd trig as not 1st, it might do what you want.
