yes, another retarded virus question:

okay, so if i've set an LFO to a two-bar cycle (2/1), is there any way to specify when the cycle begins? (i.e with a down-sawtooth lfo, what if i want it to peak at some time other that the first beat of every odd bar?)
i'm trying to get it to peak on the "and" of beat 1 of every odd bar (i.e shifted right by an 1/8 note from where it would "normally" peak), but that's not really working.
starting the seq. at different places seems to work, but that fucks the other lfos up...

i'm guessing i'll just have to draw CC sawtooths, but if anyone knows how to shift an lfos midi-sync'd cycle left/right please let me know.

and sorry as usual for the complete lack of coherent explanation.

I thought there was a way to do this in the menus, but it escapes me what it is called. I'll check when I get home, but I thought under 'Control' there was a parameter called LFO 1 Phase Init (& LFO 2 & 3 phase init), I think, maybe, this might be what you're looking for?

I could be way off here. I'll check it out and get back to you.

yeah, i tried PhaseInit in my quest last night... too lazy to touch the manual, it seemed to be shifting the lfo's start point as wanted, _until_ i started playing keys -- it re-trigs the lfo everytime you play a key. the phase is where in the lfo's cycle it jumps to when you hit a key.

damn, what's wrong with me, i really can't explain as i should...

But isn't that the way it is supposed to be?
You determine starting phase so everytime you
press a key, it starts at that determined phase.

No, retriggering the LFO for every keystroke is using the LFO as an envelope, not an LFO.

Hmm, good question Swan. I didn't try it, so

Maybe try the access mailing list?

yeah, i'm still not so sure about the mailing list... they

a) didn't answer my last question...

b) seem to be more caught up in drooling over the imaginary virus C specs than in answering ANY useful questions... i seriously doubt anyone on the list cares about A owners...

i'll try though.

Not sure if I understand your question right.

But first thing first, to use init phase is the same thing as to make LFOs retrigger. Because with Init phase=0 it means LFOs will start at a random phase everytime you depress a key. Other value than zero means starts at that determined phase everytime you depress a key. (Craig, the Env parameter is nothing but an option to make LFO oscillate only for 1 period. It's different from the conventional LFO key retrigger option.)

Now if you want the peak of the downward saw LFO to be anywhere but not at the beginning of a beat. You have to use the Init Phase and, yes, it will retrigger to start at the same phase everytime you depress a key.

I don't have my Virus b with me right now but say if you want the first beat to start the downward LFO with nothing to bottom peak to top peak and then down... Set the init phase to 64 so thatthe saw will start at pi (nothing) to 2*pi (bottom peak) to 0*pi (top peak) ....

I know this is not the start place you want but you get the idea and you can experiment with it.

I hope I understood the question right.

yeah, the prob. is it _can't_ re-trigger with each note -- or at least i don't want it to... maybe i'll have to do this with CCs, but all i want is the LFO to do what it normally does when set to 2/1 clock (i.e one cycle every 2 bars, regardless of keys pressed) only with each cycle starting somewhere other than the beginning of the first bar...

cause i'm playing lots of short notes (not some long, pad-y thing) that i want to change... the lfo gets to be a third, midi-sync'd hand that's twisting cutoffs, ocs-vol and a couple other things simultaneously.
i'd just sort of like to cut down on the CCs as much as possible, as i'm using an atari to seq...

Oh you didn't say you played a lot of short notes.
Again I haven't got to my Virus but use that trick
I mentioned up there with the LFO set to mono.
I think that should at least sound closer to what you want.

well hang on now. why not just turn off the key trigger?

we talkin 1 or 2 here?

leave the initphase at 0 and no key trigger wont that work?

OR...why not try velocity to lfo phase. will THAT Work? hmmm. fun!

influx, just to make sure we are talking about the samething, key trigger on most synths means the same thing as the Virus' init phase = 127. The Virus' Env Mode button is not what most synths means by key trigger. Most synths don't even have this option. The option makes an LFO oscillate for only 1 period to work as a ramp generator.

OK..I was thinking the wrong thing...in my E4 its either "free run" or "key sync" for the LFO. so the LFO only starts when a key is hit, and in the virus I thought that init phase was WHERE in its cycle the LFO starts when that switch is enabled (but its only on LFO2, isnt it?)

Im not looking at mine and I dont study the names of switches and knobs. just know where they are and what they do

ok. I am TOTALLY confused. I didnt want to start another thread, but I really cant figure this out. unrelated (thread stealer) but:

I set up a single I like for a part in single mode, then when I get a few parts I like, I serve up a multi to store the settings and output routing and all that, and then I throw it in multisingle mode...

NOW...Ive noticed this before but its happening right now on something Im working on and it is ANNOYING because I cant figure out why.

what happens is that the darn patch changes!!!! It gets louder and chorused when I switch to multisingle mode. WHY WHY WHY?

all the settings are exactly the same as far as I can tell. The patch is in unison 2 voice, pan spread at 0, split filter mode. I have agonized over this for about 2 hours now..tryin to figger it out.

fuck all.

oh..also..now THIS is odd...for some reason...Multi 1 wont let me run a patch on midi channel TWO. huh?

Chorus is shared between all the voices, so if you were using two different chorus settings your sound will change. The loudness could just be relative? Your mix settings in Multi mode?

Your part volumes... Have you messed with them? What about your out assignments? If you're using unison and you sum it to mono it could introduce a chorusing effect, whereas in single mode you have it going to outs 1&2?

influx -- i've noticed things like that happening on my a too... i've been writing little mini-songs (i.e just using my virus+w-30's seq. till i get huings all set up... whenever the fuck THAT happens... rgh. whatever) and for some reason it really, really seems like the relative volumes are changing. i've yet to test this rigourously (i.e write down the numbers and see if that's what they are every damn time) but i swear it seems like every once and a while a certain patch will be WAY louder than it should be...

99devils -- is the chorus really shared? i thought the first 4 singles in multi mode got their own choruses. (or chorii or whatever).

ok. it gets even wierder. I had the A set in multisingle, but it was a multi from a different track..pulled up the one in question in my seq, and the patch change set midi Ch1 to this certain patch that makes funny noize, and in THIS multi it didnt do it. WTF?!!?!?!?

its not just louder. its chorused, man. maybe its detuned osc settings or some shit but fuck all I can NOT figure out why the SAME patch would sound different used in a multi. argh

hi,
okay, someone on the mailing list suggested i use poly-pressure messages to turn off LFO sync (i.e send a value of 0) then at the appropriate moment send the wanted value (i.e on the second beat or whatever, send '16' or whatever value corresponds to the desired clock value)

hope this helps...

p.s - i'm using an ST with cubase 2... now, i'm not at home, but i'm pretty sure i've never seen poly-pressure anywhere... i can do CCs okay, but... anyone know what to do?

It may be called polyphonic aftertouch or simply aftertouch
