hi all, i see this thread is quite ancient now but i'm now where you were at then with trying to get LFO's BPM synced to an external sequencer (namely Nuendo 2.0).
i've read this thread and have tried most of what's been posted to no avail. anyone have any solid answers? this doesn't seem to be a solid type of thing though.

anyhow, my case may be unique b/c i'm looking to get a FREE RUNNING lfo to sync, not a key sync. i know how to set it all up and i know it's set up right b/c i set the RFX Flanger to 'system' and can achieve the desired effect w/ it (the Flanger's free running LFO comes around perfectly to the BPM no matter what BPM i set it to, sounds GREAT!)

but why isn't it so easy w/ a preset LFO?

i've used the BPM/60 = LFO hz for 1/4 note calculation to tweak the LFO to get it real close. then i've heard that no clock divisors are needed and the E4 syncs automatically. didn't work.

then i tried routing the appropriate clock divisior to the LFOtrg, but this stopped my free running LFO entirely once the CORD amount became above 0 (which just enables the cord in this case). has anyone experienced this?

i thought, well, why route clock to LFO triggering when we want the LFO RATE to be synced? i tried routing clock divisor to LFOrte and i got all kinds of wierdness. like at lower amounts (1-10), i couldn't tell what the hell was going on. and at higher amounts, it became clear that doing this only alters the LFO's waveform, or so it seemed...definintely didn't seem to sync the LFO rate to clock like one would think.

the only way I HAVE got this to work, is in the way i don't need at all. i'm a drummer using my E4 for a sound source, so all my samples are short drum sounds. i got the sync to work on the decay of long sustaining sounds. i took a sub bass note and applied that to one of my midi triggers. routing a clock divisor to LFOtrg, i found that the LFO would re-trigger on the sustain of the sub bass in sync w/ the BPM. again, it didn't sync the actual LFO RATE, but at least it re-triggered on beat. GREAT! but completely NOT the way i need this to work. i need a FREE RUNNING LFO RATE sync!

Any help/ideas?

lfo rate of course controls the speed of the lfo. so what you were doing really is making the lfo speed up or slow down. that is why it sounded like you were getting weird modulations or wave forms. you will get weird stuff like this all the time from the lfo. i typically get really fast pulses then the lfo will slowly start to sweep down, then fast pusles again, then continue on its sweep as if it was never interupted.

i am still at odds with this. i can't even figure this out. i will have to play around with the sampler.

right, yeah, that's what i assumed was happening. it sucks though, it's like routing clock to lfotrg doesn't work. can someone verify that routing clock to lfotrg will immediately kill a free running lfo?
anyhow, for me it does. so i tried lforate cuz it seemed logical. but doesn't seem to pull it off either. (sigh)

i hear ya, i'm all over trying to figure this out. i've written EMU, although i doubt it will help. i've read old threads, like this one , and it never seems anyone figured this out fully. i'm starting to deduce the reason is that it's impossible, again on a free run lfo RATE sync to BPM. i've got a key sync lfo to retrigger on the sustain of long sustaining notes synced to a sequencer, which has cool potential for about anyone but me (cuz i only use the E4 for no sustain drums)

anyhow, i also have asked Rich of tweakheadz.com and he has alluded to it being possible. however, he hasn't given me a solid answer and mostly just a recommendation to buy his CD that has this programming on it. i'll withold my thoughts on that idea for now

thanks to anyone for their help!

Deos anyone know how to do this with logic?

nope, sorry. but it doesn't really matter b/c the conclusion to this thread and the other's i've posted is that the syncing doesn't really work anyhow.
you'd have to read my replies carefully b/c it does work in a way, but not in the way i had hoped.

basically, LFO syncing to either internal EMU clock or an incoming MIDI clock from an external sequencer can only happen over the sustain of long sustaining notes by routing a clock divisor to LFOtrg. this triggers the LFO to re-start in sync with whatever clock divisor you've set it to.

it DOES NOT:

-- sync the LFO's rate in a way that is BPM synced. meaning, it won't sync a sine wave LFO so that it starts on say, beat one of a measure and comes around a full cycle ending perfectly on beat one of the second measure. it WILL NOT do this in my experience and extereme searching/experimenting with this. you must use the HZ calculation that is also posted somewhere in my threads that will get your LFO rate close to BPM synced.

-- it also does NOT work over the course of many short sustaining notes. i wanted a sweeping sine LFO modulating filter over my one shot drums, as to achieve a slow filter sweep that came around in perfect BPM every measure or few beats or whatever. routing clock to LFOtrg for some reason seems to cancel the "Free Run" setting of the LFO and basically, for a drum program with many single shot samples, will cause the filter sweeping to stop altogether until you take the clock routing to LFOtrg off. very odd...try for yourself.

I'm still at a loss as to how people get those perfectly BPM matched modulations happening to drums over time. Well, actually, I guess they just use their external sequencer's modulation to draw in perfect modulations. I'm a drummer, so for me that's kind of out.

What kills me is that the RFX Flanger CAN do this. It has an LFO that you can set to sync Internal (or something). If I send midi clock to my E4 while playing with the Flanger set this way, I can get EXACTLY what I'm looking for, that is an LFO sweep modulation that is totally BPM synced in it's rate. Comes around slowly for X beats and finishes it's cycle perfectly on beat. It works great and sounds great. So I naturally wanted to get this effect using the E4's Filters and LFO's...no luck. I don't get it???

Hope this thoroughly confused the fuck out of you
Just kiddin

In Logic:

Go to Synchronization Settings
Click on the MIDI tab
Check 'Transmit MIDI clock, all ports' (or something like that, not in front of Logic right now). I think you can also specify a specific MIDI port to send clock out of.

that's it.
