Adjusting Modulator settings

[Electronisounds]

Once I’ve assigned a modulator to a parameter, if I leave the modulator settings page, how do I get back to it to adjust the modulator’s settings, please?

All I can find in the manual is adding or removing a modulator, I cand find info on EDITING a modulator’s settings once created?

[ward]

Modulator settings are in the same place as the default sound engine amplitude envelopes. You can scroll through them using encoder Y.

[Electronisounds]

Awesome - Found it!

I’m not finding a way to change the SHAPE of an LFO, though? How would I do that, please?

Oh, and more more question - Can we SYNC an LFO to exact divisions of the clock?

[ward]

The extra settings (trig, shape and range for the LFO) are controlled with the top row of black buttons in the numpad.

Numpad, black keys function

I agree with you the numpad keys could be better documented. Here are the most common uses: text input for project names: the black keys are mapped like a phone keyboard with [abc] [def] [ghi]. You can see a visual next to the text input windows that shows the mapping to characters sequencer: left column are the enable/disable buttons for the four pulses. audio effects and assignable modulators: top row of three black buttons are extra parameters in some audio effects/modulators. What paramete…

Sync to BPM / time divisions is not yet possible. As a temporary solution you can manually calculate the Hz with this formula: 1 / (60 / BPM) = quarter notes in Hz.

So for example at 140 BPM:

1/4 notes: 1 / (60 / 140 BPM) = 2.333 Hz
1/8 notes: 2.333 * 2 = 4.666 Hz
1/16 notes: 2.333 * 4 = 9.333 Hz

What might also be nice to know is that you can retrigger the LFO for each note. That might also partially get you the effect you are tring to create?

[Electronisounds]

Great! This would all be really useful info to be in the manual!

Odd behaviour is happening now, though - I’ve got a sine wave LFO assigned to modulate the filter cutoff of my sound, but it’s also PANNING the sound from left to right as the LFO modulates the filter cutoff. Is there a way to stop the stereo panning efftect from happening? It’s a LFO on a BASS sound, and should not pan in the stereo field. I only want to effect the filter cutoff.

Still stuck on this… Just want to put an LFO on a filter without having it pan the sound in the stereo field…

@Electronisounds

I’ve got a sine wave LFO assigned to modulate the filter cutoff of my sound, but it’s also PANNING the sound from left to right as the LFO modulates the filter cutoff.

So what I think is happening here is:

• After the sound engine the first effect in the chain is stereo. Without this effect you would only hear a mono synth on the left speaker so I wouldn’t remove it.
• Then comes the filter. Because the stereo effect outputs 2 channels the filter filters 2 channels.

The LFO is assigned to the filter freq. Because modulators are polyphonic/multichannel it can happen that the LFO’s of channel 1 and channel 2 are not at the same position or out of phase. Maybe on channel 1 the LFO goes downwards while on channel 2 it goes upwards: now it sounds like it is panning!

There are two solutions:

1. Change the order of the effects to: sound engine → filter → stereo. Then the filter only filters a single channel and thus the ‘panning effect’ goes away.
2. Set the LFO’s trig parameter to note. Both LFO channels will reset to phase 0 when a note starts so they are synced and the ‘panning effect’ goes away. (this only works if the sound engine’s polyphony is set to 1)

To put the filter on a different place you have to remove it and then add it again at a different position. When adding an audio effect after choosing the type you can set where it is inserted using encoder X and then pressing [yes] to confirm.

[Electronisounds]

Unfortunately, this solution did not work for me…

I removed the LFO from the default filter on the SUBTRACTIVE engine.
I added a new filter to the FX section of the track and put it BEFORE the STEREO effect.
I assigned a sine wave LFO to the new filter.

It is still panning from left to right - same as before.

I double checked, and there is no LFO assigned to the default filter on the subtractive engine and for sure the new filter effect is routed BEFORE the stereo effect on the channel effects.

For clarity, In this photo we can see that the stereo effect is routed after the filter in the FX chain.

[ward]

Thanks for the photo. It seems like you are triggering two voices using unison?

Then can you try this on the subtractive filter:

@ward

Set the LFO’s trig parameter to note.

And can you also post a photo of the LFO?

[Electronisounds]

Yes, it’s a unison sound - I’m trying to use the factory preset, “bass-wide-reese”.

The issue of using a trig set to NOTE mode for the LFO is that the LFO no longer works.

I’m just trying to have a slow moving free LFO on the filter cutoff.

NOTE mode resets the LFO everytime a note is triggered, which defeats the purpose of what I’m trying to do.

Here’s a photo of the LFO set to NOTE mode - but now you don’t hear the LFO moving the filter cutoff like I’m trying to acheive.

@Electronisounds

The issue of using a trig set to NOTE mode for the LFO is that the LFO no longer works.

So assignable modulators are only moving/active when sound is actually playing. Maybe they start moving again when you press a key on the keyboard? I don’t have a PolyPulse in front of me right now so I can’t check.

If however the LFO is also not playing when sound is playing then that is definitely a bug.

Ah right I understand. Then for now I’m afraid there is no solution.

I will put both syncable LFO’s and the option to choose between multi/poly modulation (current situation) and single/mono modulation (which would solve the panning issue) on my to-do list.

[Electronisounds]

Ok, so for now - no solution.
I look forward to this being added in a firmware update.
Thanks!

Hi I following this
I still have some Q about the screen display ( I dont remember this being in the manual, but maybe wrong
A: Quad Ringmod- B: noise where do I Go from here to change those A & B

What are the informations in the squres 2 rows of 8 ? Are the for the slot LFO only ?

So subtractive has three options controlled by the top row of black buttons on the numpad:

• top left button: sound source A which currently has only one mode (quad RM), therefore pressing this button does not do anything.
• top middle button: filter type (12dB svf with variable shape / 12dB lowpass)
• top right button: sound source B (noise / sample list)

@radpix

What are the informations in the squres 2 rows of 8 ? Are the for the slot LFO only ?

So these 8 rectangles show the modulators movement. Because the modulator system is polyphonic/multichannel there are 8 plots because each track has a max polyphony of 8. As the synth in the image below has polyphony set to 4 and 4 voices are playing you see only 4 plots filled with the LFO:

Modulation can be bipolar so there is a horizontal line in the middle at 0.

[ward]

I’ve added an option to sync the LFO to the main clock in 0.1.29: jan 2025 update. You can now set retrigger to sync which also fixes the panning problem!
