My goal is is to apply a flanger to a guitar part, so it goes "up" in the first bar and then "down" in the second bar. I am using a Mod Delay for flanging, so I have an LFO. Any tips?
Thanks, Andrés

How do I sync a flanger's rise and fall with the tempo of the music?

Same as Delay.
Divide 60,000 by the tempo of the song will give u the quater beat. Divide or multiple from there to get your correct change.

Unless your flanger has midi sync it will eventually drift out of sync. Especially if you are trying to do a long slow oscillation. You might have to to stop and do some puch ins when it drifts or just copy and past a few bars where the flanger was right on.
You might have more luck with an Auto Wah type effect because it can be triggered by the velocity of the note so it will always start when you strike the chord. A flanger will keep going based on it's settings and you will have to follow the flanger instead of it following you.
On "How Soon Is Now" Johhny Mar could only record the vibrato part for about 8 seconds before the different amps vibratos drifted apart. Then they would keep punching in until the whole song was finished.

well, this is Digidesign's Mod Delay. So I have the possibility to automate the LFO so it turns to zero and back to the proper rate. Maybe that will be like triggering it again and again.
My point is, is there a way to know when will the flanger righ the highest frequency point and then start goind down in pitch?

The LFO is what determines how long it takes to do the high to low sweep. Can you dial in an exact frequency on the LFO? If so then it's just a math problem. HZ is cycles per second so a 1hz LFO is a one second sweep. If you want it to cover a couple bars then you would need it be slower than 1hz.
At 120BPM a 4 beat LFO would be .5hz.
The trick will be getting it to start the cycle on beat and that is where midi sync or velocity triggering will be neccessary. You might be able to do it manually by turning it on right at the exact beginning of the bar.

Thanks for the help, Texas.
I'm gonna try 3 things, all with automation:
1) automate the bypass of the effect, turning it on when the bar starts. That will maybe reset the LFO.
2) Automate the LFO speed.
3) Automate the delay time. After all, the LFO modulates the delay time, right? So maybe it's better to take the shortcut and automate this instead.
What do you think?

It could work. Turning it on and off may give you some glitches but you never know until you try it.
I'm not sure what you mean about automating the delay time because if you can control the delay time on the fly then you are pretty much bypassing the LFO.
I get a little confused between phasing and flanging but as I understand it phasing is an LFO controlled notch filter and flanging is an LFO controlled delay.
You might be able to get the effect you want with a Wah pedal. Then you can control the peaks perfectly. A Wah is pretty much a manual phaser. It may not be obvious enough though. You might get a cool effect by double tracking the guitar and using a Wah pedal but start one track with the pedal up and the other track with the pedal down.
You could also record the guitar dry and then reamp the overdubs using the wah pedal. That way you get a lot more phase and comb filtering because both tracks will use the same source signal. If you did that 2-4 times you might get a pretty deep flange effect and have a cool stereo spread.

I don't know what I am talking about but here it goes!
Think back how original flanging was done: slowing down one of two synced tape machines.
If you duplicate the track and select each bar of the duplicate track and slow it down slightly you might be able to create a natural flange.
If you found a time that peaked in the middle of the bar you could do that to ever other bar and then find the time that gives you the low point of the flange and do that to the remaining bars.
I have no idea if this will even come close to working but I am going to try it myself just to see what happens.
