Hive - strange behaviour of S&H-LFO in sync-mode

[SamDi]

My use-case: I want S&H-LFO to give me a new random value, in e.g. every bar. So I set LFO to S&H, timebase to 1/1 and restart to sync. But played notes are in my example 16th. Which means all notes in a bar shall share one S&H value. But as it seems, there is no way to reach that, because with the trigger of a new note, the LFO always deliver a new value, even when "Restart" is set to "sync" and shouldn't in my opinion.

Is it a bug or a feature?

For me, it feels like a misbehaviour.

Hi Sam,

the LFOs in Hive are polyphonic, so there's one per voice. "Sync" synchronises their phase position between the 16 voices, not their random amplitudes (when using the random hold waveform, for example). Each voice uses its own random shape in general.
The LFO restart mode that might help you though is "Single".
From the user guide: "Single - All voices share the same LFO"

Just keep in mind, in order to retain the same random LFO shape for all played notes, always have notes in your sequence overlapping. Once you have a gap with no notes pressed, the next note will start a new random LFO shape.

Hi Viktor,

thanks for your answer, but I have to contradict.

"Sync" synchronises their phase position between the 16 voices, not their random amplitudes (when using the random hold waveform, for example).

I am not talking about different values for different voices. I am talking about a series of single notes, which should get a value from a continously running LFO, with a very slow rate.

The manual says:
"Sync ....................LFOs of all voices are synchronized to the host, ..."

So when I choose e.g. a sine wave, set "restart" to "sync" and for "time base" I choose "4/1", then it behaves as it should:

The sine wave is starting with 0° at the beginning of the first bar of four, and independently of triggering new notes the LFO keeps running without beeing restarted with every new note, because it's synced to the host. This meets my expectation.

But as soon, as I switch then from sine wave to ANY random function, every new note delivers a new random value, independently of which time base I choose. So when I want to generate and keep a new random value for e.g every bar, this is not possible, because every new note triggers the LFO to spit out a new random value.

Hi Sam,

a series of single notes will trigger one voice after another, so yes, you are in fact talking about different voices.

Also keep in mind that same phase position does not mean same amplitude at that position if you use random LFO shapes.
A sine wave LFO has a consistent amplitude for a specific phase position, as it's always the same shape.
A random LFO shape is randomized each time it's retriggered, so even if you synchronize phase positions, the amplitude at that phase position will always be a different one.

You play one note, let's say 'Voice 1' plays that note, and the LFO for Voice 1 uses one randomized LFO shape.
Your next note is played on 'Voice 2' and it will use the LFO for Voice 2, so that's a different LFO, and if set to a random shape, the Voice 2 LFO will have a different random shape than Voice 1 LFO.

If you now use the LFOs in Sync, then you're syncing up their phase positions, but random LFOs will still have different amplitudes even at the same phase position, as you're cycling through the available voices, each voice using its own random LFO shape.

Like I described, you should therefore use the "Single" mode, which uses the same LFO shapes for all voices as long as notes are held. Letting go of all notes will get you a new random LFO shape on the next played note.

Thanks again, Vikto. With this explantation it gets much clearer to me. But there is one question left from my side. Is there any opportunity with Hive to get my use-case fulfilled, means to get a slowly changing S&H-Value over time with all notes/voices having access to the same value and without the need to keep always one note active to not reset the LFO?
