Hi,

hope someone can help me, I`m trying to get a synchroniced LFO, so what I
tried was setting the LFO to free 
run and a 8/1 clock sync in the LFO menue.
My pattern is 8 bars long, and what happens is quiet strange:

1. LFO don`t starts at zero as it should when I start the pattern
2. it starts at zero if the pattern is looping first time and stops after 6
bars

I tried to get it right by the clock modulations sources, but it seems they
retrigger always playing notes.

what`s going wrong?

thanx,
Christop

What waveform are you using?  The reason I
ask is my recollection is that the initial starting value (phase = 0) is not
what I at least expected.  For example the pulse-type waves I believe start
at an on value and not zero.

Also is this repeatable every time you start the pattern from a full-stop?
Guessing here but the XX-7 likely keeps track of a bar count from the start
of sequencing (time=0).  Pausing the sequence, which is stopping without
returning the position to start, will not reset this position.  So (again
speculating) playing a one bar pattern four times followed by an 8 bar
pattern (whether paused or not between) will have the 8 bar pattern
"see" the LFO as if it was starting in mid-phase as the change in patterns I
do not believe restarts the LFO phases.

Again I am speculating.

Hi,

What waveform are you using?

I used a sawtooth wave with the cord:
LFO+ -> Amp  +96 (initial vol.-96)

So what should happen with the synchronized LFO (8/1) is that it´s beginning
at zero and going up to the cord 
amount.

Also is this repeatable every time you start the pattern from a full-stop?

Yes, and so far I really have to believe it`s a bug, it works using clocks
till 1/1 but as I go above that time, 
the XX-7 seems to half the time in the beginning LFO, so if I choose a 2/1
sync the LFO starts at a value he 
would be after 1 bar.  

Guessing here but the XX-7 likely keeps track of a bar count from the start
of sequencing (time=0)

Yes, but I start at time 0 as I start the pattern from the beginning.

So (again
speculating) playing a one bar pattern four times followed by an 8 bar
pattern (whether paused or not between) will have the 8 bar pattern
"see" the LFO as if it was starting in mid-phase as the change in patterns I
do not believe restarts the LFO phases.

Ok, that could be, but in my experiment I do not switch patterns, just
playing one from the beginning.
I didn`t choosed a tempo track so far.

thanx,
Christo
