Bassdrum sound with Dune 3 -sound playback bug ?

[Marsi 27]

Yesterday I wanted to compare the Sylenth1 with the Dune 3 and the Spire because of the sound character.
I noticed that the Dune 3 does not reproduce the sound evenly when playing a simple bass drum sound with only 2 oscillators and one layer (polyphony = 4) in contrast to the Sylenth and Spire.
Some notes played softer every now and then, it sounds like a partially canceled sound.
The notes are not accidentally double-triggered.
What could be the reason for this ?
With Sylenth and Spire, the same programmed bass drum sound is reproduced with equal power.

Upload the preset.

Sounds like velocity is affecting something, check the mod matrix

Switch to mono, you don't need polyphony for a kick drum, and set Unison Voices to 1, so you are only using one layer.

It is an edited init preset, only 1 layer, no velocity, no mod matrix.
An at the same way edited spire init preset doesn‘ t have this problem.

As Kriminal said upload the preset so we can take a look at it. We've both been using DUNE since version 1 so there's a good chance we can answer the question if we can simply examine the preset.

Does the factory preset "Kick Me ST" exhibit the same issue?

Also try turning Osc Reset On (yes it makes a difference even with density set to 1).

You can also try this to stop pitch tracking to see it that solves the issue for you.

I would like to upload the preset and audio examples here, but unfortunately this is not possible with mp3, wave and fxp files.

"The extension fxp is not allowed." etc....

Zip them up

O.k.
Here are the audio examples and the Dune 3 Bass Drum Preset used.

turning off OSC2 solved the problem (no idea why you are using two doing exactly the same thing), as did setting init phase to zero on both, so its obviously a phase issue

Thank you very much, that's it.
Thanks for the info. This is not necessary with the other VSTi's, which is why I would not have thought of it.

The others prob have osc reset on by default (assuming they have a free run option)

Haven't looked at them for years, so don't recall
