Granular synthesizer from Dan Trueman, adapted in 2007 by ivica bukvic
re-compiled and prepared for organelle by patrick pagano.
testing to see if declare works for .so files
disis_munger.zip (1.6 MB)
you feed it a live audio stream
Aux turns the granulator on/off
the knobs currently do not print but
1 = tempo of grains
2/3 grain amount
4 blend
first couple of buttons set scaling functions
Ivica’s white paper is in the folder for a history lesson
gosh i hope it works!
i’m sorry to say that i think the answer is no. i pressed aux and turned all the knobs a lot and the audio stream didn’t change. only knob 4 is changing the volume.
same here ;-(
i knew it but in the spirit of open source development i tried
if you are interested, this will install the research libraries for munger~
1.) Place patch on USB [please do not rename it]
2.) Click AUX and then Reboot when it completes
then you can run
I am going to be changing it up and it’s a BETA
if folks who try can give feedback i would be grateful
cheers~
okay, i got that working okay. it’s a cool effect. it seems quite an extreme effect (after just a little play around) so i don’t know if there’s a way to make the settings go from subtle to extreme. perhaps a larger grain option? or something.
Hi Andy
This was/is about getting the libraries to actually work
I’ll appreciate your feedback when the patch is fleshed out [this as you can see does not even have a functioning menu yet] There are about 10 different parameters i “locked down” for the sake of testing but now that they actually work 
try this one too
oh yes! it’s very nice! i especially like the gentler but complex marimba type sounds you can get by pushing the low notes on the keyboard.
one thing though, page 4 should come with a warning. it’s very easy to get some awful shrill piercing feedback with certain settings. that delay is deadly!
… and i’m really excited about “PLUNK” if you get time to do that!
yes for sure!
these are both really just tests i made to test that the libs are installing properly.
Ideally the declare -path would handle that but it does not work with .so files
It DOES work with specific libs like FFtease & LyonPotpourri but these want to be IN your /usr/lib
i have one more “research.so” that i am preparing before i start the adaptation of these two important sets of externals by Davide Rochesso, Zack Settel * Ivica Bukvic, Luke Dubois and Dan Trueman.
Plunk is going to feature a generative sequencer by Kyle Werle, our resident MIDI/AI interface Wizzo and will be available in March. There will also be full featured versions specifically made for the pisound because we get a little more processing overhead with the raspi. For example i reduced the fluidflow~ “bubbles” down to 16 or 32 BPS [Bubbles per second ha!] but the suggested amount is 256 and the organelle locks up with that many streams o fluid
if you read up on dynamic library loading, and specifically rpath - you will learn how to build things that do not require so’s to be in /usr/lib (or anywhere else hardcoded)
don’t believe me? look at my brds external, you will see it quite happily picks up my so libraries from the patch directory , this is because I set the rpath correctly when i built it.
That’s nice. I’ll put rpath on my todo list!
cheers~

here’s an updated installer
fluidflow~ ANDthe munger~ are betas and the whole sets are being designed presently
