Ok so I'm trying to modulate with a sawtooth LFO (or sine for that matter, but let's talk about the sawtooth)


The saw LFO starts at "zero", go up, and then goes maximum negative and goes back up towards "zero".

If I use LFO1~ and tie it to pitch, I get pitch rising above normal, then dropping below normal. Ok.

If I use LFO1+ then I START with a pitch above normal, it rises, then falls to normal and rises again in a saw pattern I would expect.


How can I avoid the pitch STARTING ABOVE NORMAL??? I am trying to do sync effects and obviously this ruins everything!



Please help - I'm open to anything and have tried everything it feels like!!!

Have you tried to sum the LFO with a DC offset?

If the LFO begins above zero by a certain amount then by adding that negative amount you would bring it to zero.

No sorry, I don't think this is right.

I misunderstood your question.

You want a positive modulation, but by using LFO+ is basically shifts the LFO up a certain amount. So then when you add DC value you are only undoing the shift on LFO~.

The only thing that comes to mind now is to try and use the diode to block the - values, but then it would be constant on some area.

I thought about it a bunch, I think what I want is something like:


LFO~ PITCH 10%
LFO~ DIODE -100%
DIODE GATE 1%
GATE LFO1RETRIG 100%

Does that look right? Basically do one saw cycle from zero to zero, and after it crosses zero the -100% LFO through DIODE will rise, once it hits 1% it will retrigger the LFO.

Maybe even I should put DIODE GAIN4X 100% and then GAIN4X into GATE so that it'd detect the retrigger as soon as possible.


What do you think? [i'm at work so no emu handy]

Yes, this would work.

ok seemed to work great after some testing!

except I went

LFO~ DIODE -100%
DIODE SWITCH 100%
SWITCH LFO1RETRIG 100%

GATE wasn't the way to go, doesn't do what I thought. SWITCH immediately goes HIGH when anything over 0 hits, so I also didn't need GAIN4X

Love that emu! Thanks for the thoughts plus
