LFO Sync and Reset?

Hi,

maybe its a really obvious answer; but I wonder how I can use multiple LFO’s to control parameters, and these LFO’s are being reset in their phase when a gate plays.

For example, I have one sequencer module on the SSP, it sends G1 to all LFO’s, and those LFO’s should reset when G1 is triggered.

So far my LFO’s dont reset. Does anyone of you have some tricks how to set up modulation signals that will sync and reset to the Sequencer?

Thank you!

sorry, I don’t quite follow this…
you are saying you want to reset phase, when there is a gate?

tl;dr; LFO sync is an audio sync, not a reset … so uses a zero crossing, not a trig to ‘reset’

more detail, so, I checked the code…
(it was quicker than setting up my SSP for a test, and I wanted to make sure there weren’t any bugs!)

and indeed, this reflects my expectation…

sync uses a zero crossing zero (positive) ‘trigger’, i.e. going < 0 to > 0
so won’t work with a trig/gate, since that assume a 0 to 1 transition (usually I do at around 0.2-0.5)

why? because sync signals on oscillators, primary intention is an audio rate sync across oscillators i.e. to sync two oscillators - so the LFO behaviour is 100% correct.

how can use with a trig/gate?
simple - use an offset on the input (or gate output) of -0.5, this will shift its range to -0.5 to 0.5,
giving you the zero crossing that you need to ‘reset phase’ on the oscillator.

Wowzer!

Thanks for the swift response. That is indeed what I was looking for.

I guess the input of the LFO is the Level?

?
what do you mean input … lfo’s are modulator/oscillators?
level = gain of the LFO

if you mean where to apply the above offset, no…
there is a scale/offset feature for each input/output… you can see it next to the small scopes down on the bottom right… you can adjust these with LS/RS + enc1-4

have you seen my community wiki for the SSP?

I wasn’t sure where to write this, so I’ll just ask here.

Is there a module with an LFO that can sync its rate to the clock?
It’s a luxurious problem to have, but there are so many SSP modules now that I can’t keep track of everything it can do :laughing:.
I was thinking about trying to make a simple LFO VST for CV control, but I don’t want to reinvent the wheel, so if such a module already exists, please let me know.

OMOD

not only is it clocked, but allows 8 sub division on the clock… and yeah, has reset.
also has end of cycle trigs for fun too, 8 waveforms, oh, and you can phase shift from the clock too…

id recommend pairing it up with CLKD, which allows you to also sync with midi.
quite useful for trigging envelopes.

also, consider LOGI, a great way to combine clock trigs in interesting ways :wink:

Ive built this in a modular way, the idea being you can combine things in different combinations, to use and abuse clocks…

Thank you for letting me know.
Wow, that module is packed with wonderful features. It includes everything I’ve been wanting.
With a module like this, I wouldn’t need to build it myself, but on the other hand, I’ve started to think it could be fun to use your module as a model and try recreating it in RNBO, almost like sketching practice.

yeah, its a fun module… initially I was inspired by divkids ochd, hence the related clocks.
but as I played with the concept, I realised there was so many things you can do related with clocks, I think Id just finished with CLKD which has some interesting bits in it too.

I def recommend messing about with these concepts in rnbo, the more you dig into the details, the more you’ll find some interesting quirks/decisions e.g what you do when you notice the clocks change…
(this is what the mysteriously titled “trigsync” does on CLKD, a difficult thing to explain without understanding some oddities about clocks and drift :))

anyway, have fun…
