Higher granular dials in Sfxr can open a world of sounds

[musikBear]

Enhancement Summary

Adding a multiplier for the pitch-slide array in Sfxr will make this generator able to create significantly more versatile output

Justification

more sounds from this plugin

Mockup

I have fooled around with Sfxr, mostly because i really never paid it much attention. That is an oversight. SFxr has amazing possibilities.
In this picture i have settings for a sweetspot for all 4 dials -I include the preset

Changing any of the framed dial-values 3. decimal will result in extreme changes of output.
If we had a fourth or perhaps even a fifth decimal-option, a tremendous sound-scape would be available
For demo change START .322 to .323 !
Afair, there is no LMMS plugin that shows that kind of dramatic change in output, when a dial value is changed in 3. decimal.

@musikBear The step size is set by the 0.001 value in these two models. Poke there.

lmms/plugins/sfxr/sfxr.h

Line 132 in 953a0b1

FloatModel( val, 0.0, 1.0, 0.001, parent, displayName )

@zonkmachine Great spot! This should be simple -can you assign me to this?

This was a failure
It seams that the point-of-change is not possible to 'catch'
I worked on several dials, but Change| ChangeSpd gave the most understandable result
In stable 1.2.1 we have a super short sound at setting 0.746.
At 0.747 the whole sweep through all octaves
In my Master, i therefore changed the input to 0.0001 that was expected to catch the output from sweetspot 0.746 to 0.746 + 0.000n
And it did. The output was identical with super short sound at 0.746.
That continues to 0.7468, then it goes into whole sweep through all octaves!
I then added 1 more decimal
At 0.74681 identical with super short sound at 0.746.
At 0.74682 into whole sweep through all octaves
Added 2 more decimals..
At 0.7468203 identical with super short sound at 0.746.
At 0.7468204 into whole sweep through all octaves
Looks like This is not possible.
I back out -Sorry

So you basically found a quirk in sfxr. I kind of suspected it but there's no knowing if it can be usable without probing into the matter. Now we know. Closing for now.
