@agroschim wow very clean structure!

I want to incorporate slur's float_crusher in there and then add the waveshapping.

@slur The brain button is used to switch the unit to Filter mode. Waveshapping, Pitch Shifter, Delay, Step filter (sweep?). Also used for setting a loading presets.

Edit: here's the manual - http://www.otomachines.com/BISCUIT-usermanual.pdf

the floatcrusher also tries to do the oto waveshaping but... different

Thank you. A clean structure is very useful. As is commenting you patches, what i will probably do sooner or later. Helps when someone (or maybe i myself) is trying to 'reverse engineer' the patch.

so i now tried atarikai's
as agroschim already corrected the vcf is a bandpass not a lowpass
also i think the samplerate reduction is done before the waveshaping...
but i'm not so sure if this does even make a difference

It does not make any difference.

damn you are right....
also i suggest adding a oversampling of 2 or 4 to get more out of the lowpass
but yet again not sure if this is a good choice or could even be contra productive

p.s. pd aaaaaaarrrrrrghh

Here's a more descent version. I did add some waveshaping effects. The rectifyers work okay, i guess. The rectify down is somewhat of a cheap trick, but sounds fine. Bat fuzz doesn't work as expected, i would be glad if someone could take a look at it. Swap was easy ( ).

I took slur's advice and made the frequency button logarithmic. I also added an on/off button to the clock (aka change samplerate effetc), as it may be undesired sometimes

For testing and understanding the "Krümel M." i will upload a simple kick with a oscilloscope too.

hitting rec/down seems to kill the sound for good, for me.

overall I think the sounds achieved in the previous version are nicer. Couldn't really get any musical distortion out of this one

The filter knob now is logarithmic, try a higher cutoff. I made this mistake myself.

Edit: I made a stupid mistake in the bat fuzz subpatch.

i made some changes to krümel i thought where necessary or something else

• replaced the os dependent spigot~
• simplified some stuff
• complified some other stuff
• made the gui smaller and much more ugly
• added the bit reduction from my floatcrusher
• made the filter section (hopefully!) samplerate independent

• added experimental oversample capabilities for you to test if its a useful mod or not (feedback please!)

i didn't test much and especially not every change so keep your eyes open for bugs

@agroshim
what's the purpose of rect down? as far as i understand it it should be sqrt(pow(sig~,2)) which is exactly the same as rect up
the way it works now is something like clip 0 1 but with a light twist
the lower part of the waveform which is cut away is not at -1 after the sig*2-1 its at 0

That is exactly what it should do... omg i was so tired when i did this.

I will test your improved Krümel soon.

-bug-fixes!!
-simplification of bat fuzz
-filter changes
-other stuff
-rect down with clip
-(new) rect c to simulate the behaviour of the old rect down

the msi version is the most recent
in ms i tried to make the biquad based filters more samplerate independent....
well..... its better than before.........

i stands for "iemlib filters"
the vcf are the only ones i could find which are samplerate independent so i used them
does anybody know a better solution?
which one sounds better?

i know there are some things which could be done better.... like switching the inactive filters off
well... you do it!

no feedback?
well next version
with level compensation for batfuzz and mute
not perfect but bearable

http://www.pdpatchrepo.info/hurleur/kruemel_msi.pd

Oh, i am so sorry. I totally forgot this as i was strugeling with other things. Looks descent sofar, will have to give it a try with some samples and report.

New Version of mine:

* added slurs bat fuzz
* added slurs oversampling
* changed the maximum samplerate to 44000Hz (don't forget to oversample before using rates over 22000Hz!)
*clock scale is now logarithmic
* simplified the rect down
* kept my interface
* kept the [spigot~]

Have fun.

You should really get rid of the [spigot~]. It doesn't work on Windows, and there's nothing it can do that [*~] can't.
