mungo c0

Post by timoka » Wed Apr 06, 2016 1:00 pm

from the mungo website:

c0

Combining a traditional bucket brigade delay with high performance computation allows realtime convolution under CV control.
Entirely digital in its implementation the delay lacks any of the artefacts commonly associated with bucket brigade devices and
includes an asynchronous sample rate convertor output for sharp low pass filtering.
The convolution allows instrument or room resonances from impulse responses to be applied to any signal, or production of arbitrary filter types.

and the picture in the userguide:

Woah. Never thought I'd see a convolution module.

c0ol! somewhat c0nfusing! most likely c0stly and c0mpletely unique sounding! c0ngratulations John on c0nvoluting our expectations yet again.

So, I guess I'll need four of these to get True Stereo impulse processing :moneyburn:

Wow... this looks really cool.
Having 7 other Mungo modules in my rack, it will probably be impossible to resist this one.

Looking forward to the audio / video demo.

Seems odd that you would need to remove the SD card in order to adjust the delay time???

Maybe I am not fully understanding. The manual reads like you would follow these steps to use the module.

1. insert the card to load the waveform by using the "load" button
2. remove the card
3. use the "load" button and zoom to adjust the delay time.

This means you would have to insert and remove the SD card every time you wish to add a new waveform and adjust the delay time. I wonder if the delay time stays set while loading new waveforms from the card. This way if you have a delay time you like, you can audition new sounds from the card without the need to remove the card each time.

This one needs some proper demos! Didn't think convolution would make it into eurorack, hope this could be it. Or at least a start.
My latest release, including vinyl!

if i had to guess this probably means that if you are using a sample from the sd card it will change the frequency of the sample and if you are not using an sd card it will change the frequency(time) of the delay?

How does a button adjust delay time anyway?
The frequency of the file on the SD card is modulated by the frequency modulation input, and I assume that to be true if the card is in or not.
Is the delay time of the BBD set initially by the length of the sample, then pressing the button toggles polarity? It does say "adjust delay time up/down"?

Just to clarify is it an analog BBD module with digital control, or a digital implementation of a BBD? Is it just me (maybe it's Mungo :hmm: ) but the description leaves it a bit open to interpretation. However, this may not be important, i don't even understand what it is supposed to do.

Yes, we know you have 7 mungo modules in your rack! No need to tell us again and again and again. :lol:

The description says "Entirely digital implementation" and I would guess continues to use his FPGA backend.

yes, waiting for good demos. if this module does what i think it does then i really think that this might be my next mungo purchase!

I'm not really bragging, just multiple attempts at establishing my superiority and elitism.

It would be more effective if you were 'presenting' each module in a different post though :)

Interested about the convolution, not sure how reducing sampling rate would work nicely in that context though..

The description is very promising, but cryptic at times. Particularly this: "variable slew rate applied to the linear frequency. Exponentially scalled". What is the meaning of that in the context of convolution?? :deadbanana:

I am guessing that the input sampling frequency is convolved with the samples and so the slew rate would be how quickly the user is able to update that convolution process. Maybe we will get more information from Mungo on this thread.
