Mungo Modules

[Net]

@jwm

…and like the c1, based on your demos up thread, it does seem wholly dependent on what you throw at it in terms of dialing in base frequency and band width.

It’s most definitely like c1 in this regard. Results have been all over the place as I’ve tried various inputs. The interaction of base frequency, width and band count is more complex than I expected. Beginning to get quite excited about it all nevertheless.

Hey everyone, I recently had the opportunity to get a storage strip module for my mungo family.

I’m uncertain on the exact configuration of the zoom jumper cables.

Could someone give me a hand?

Attached images show what I’ve got now.
I have the cables on the middle pins on the d0 and g0 is that right>

Any help would be really appreciated. I haven’t plugged anything in yet in case they explode

[desolationjones]

Seems good. You can daisy chain the zoom pins instead if it’s easier. Don’t plug anything into the ground or 3.3V rows though.

[flec8]

Works great.
Thanks for the heads up

Can anyone with a g0 and storage strip chime in -

Does loading a new preset with the storage strip always cause the g0 to load a new wav file?
Even with the same sample loaded it seems to access the card and try to load it. Makes using the ‘clock’ feature on the Storage Strip impossible with the g0

[jwm]

ok, starting to make some v0 progress, here is a little thing i managed to capture today

a short droning loop caught in a tyme sefari with its pitch sequenced, this hits the synthesis input in v0

quanta noise from a quantum rainbow 2, this hits analysis on v0

this is the result, with a wonky envelope from kermit modulating the base frequency, the band count is set…i dunno somewhere zoomed out around 1 o clock, and just kinda wiggling the decay control here and there. its getting there…

onward!

What exactly are these things on the back of the c1?

Fab textures. I had a cool thing going earlier with a gate going into the analysis latch, but a few tweaks later it all vanished into the great span of fleeting values that is a rookie-operated Mungo. Having some noise-floor issues as well; all my Mungoes seem to give off a fair bit of noise. I think it’s probably just that some of the ranges that interest me the most happen to be those near the processing thresholds.

But I’m enjoying learning as I go along. I’ve found the following discrete functions in m0:

• 3→1 audio mixer with inverting gain
• 3(4)→1 CV mixer
• ring modulator (with attenuverting envelope assignable to carrier modulation)
• AD/AR envelope (or gated LFO, or at audio rates, adjustable-waveform sawtooth/triangle oscillator) with trigger delay
• sequencer (with gates patched into modulation, channel 1, channel 2, channel 3 and envelope trigger, and the envelope assigned to modulation amount, you can make complex, semi-slewed CV patterns)

Nothing unique to Mungo but a solid utility.

[desolationjones]

I think you will have to ask John. My guess is they are full debug headers for all inputs and outputs to use with a custom test jig. Maybe ISP, too.

[jwm]

not really noticing a noise floor problem per se, but i do notice that if i zoom and twist into um, frequency-less? territory, i hear all kinds of weirdo digital noise in the background on the output, but then when i navigate back to proper sections it goes away when audio is present…

what power supply are you using? i have mine on an intellijel, which i feel like i read john isn’t crazy about the design of…

[Net]

I’m using an intellijel 4U 104 hp skiff with the standard PSU. It’s quite possible if not probable that power distribution is the culprit in this situation. I have of course even wondered how different the experience would be with a Mungo scaleable power supply, but it seems like something I might try properly to diagnose first. And since I’m lazy to a fault I’ve just tried to do careful gain staging instead for the time being.

[corbetta]

has anyone tried the scaleable power supply? I’m on the verge of ordering it, but my system would need two, and it gets expensive quick that way…

[AndersSkibsted]

Interested to hear as well if anyone has experience with it.
If what John writes on the website holds up, it looks quite impressive. But of course, good is often expensive.

I spent a long time with v0 last night. Here is the highlight, when the patch seemed to be coming together.

The analysis input is the ‘custard’ output from an unmodulated NLC brain custard. The synthesis input is a drum patch coming from an external device. This also provided NLC wangernumb with a clock, from which I sent gates to the analysis freeze and to an envelope modulating v0’s decay. I processed the output a bit in Ableton (chorus, EQ, dynamics). The band count was at max, or just below (this seems to give the smoothest but also the quietest signals).

[Ravel]

Wow, that sounds unbelievable!

Alright gang, I’m coming up with an outline for an unofficial d0 video manual and I’d appreciate some input since I’ve never attempted something like this before. The goal is to A: demystify the module since Mungo stuff has such an unshakable reputation for being obtuse, and B: show the extreme range of applications the d0 is capable of.

What I’d like to know is, does the below look like too much? not enough? what would you add or remove? And does it make more sense to make each section its own video, or do an all in one video with time stamps?

Here’s the outline I’ve come up with so far:

1. Intro and Overview
   a. Panel i/o and controls
   b. detailed example of the zoom function
   c. examples of min/max delay settings, min/max modulation amount, min/max gain on channel A
   d. summing A into B
   e. DC cut
   f. clock input behavior
   g. in depth look at slew

2. Audio Echoes
   a. single delay w/out feedback
   b. single delay w/ feedback using onboard summing
   c. double tap delay
   d. doubling delay time by patching channels in series
   e. dual independent delays
   f. ping pong delay
   g. emulating a tape delay

3. Audio Phasing and Karplus Strong
   a. vibrato, chorus, flange, and comb filtering
   b. stereo chorus
   c. unclocked phase shifting
   d. clocked phase shifting
   e. Karplus-Strong
   f. 3 ways to track pitch (clocking to oscillator, modulation input, MIDI)

4. Phase Modulation
   a. clocked vs. unclocked PM
   b. single operator PM and feedback
   c. 2 operator PM
   d. 3 operator PM
   e. Cross modulation PM
   f. slew’s effect on PM patches

5. Delaying Control Voltages
   a. simple gate/trigger delays
   b. swinging a clock
   c. shift registers and phased LFO’s
   d. oddities/limitations of CV feedback
   e. mangling CV

6. Miscellaneous creative patches
   a. many types of distortion
   b. building a frequency shifter
   c. pseudo-pitch shifting
   d. pseudo reverbs with allpass filters
   e. giving your filters more character by playing with phase

Wonderful. I’ve been considering doing some videos myself of some of the least-demoed ones: chiefly m0 and f0, possibly s0; definitely not d0 as for some reason I really do find it one of the hardest Mungoes. Time after time it challenges my imagination and I can’t think of things to do with it. I know I’m going to get around to a proper harmonic karplus sequence eventually, but otherwise I keep seeing it as an ordinary delay. What a waste! Please do make this video manual!

Personally I would prefer a single timestamped video. It seems a bit neater than a series of discrete videos, but that’s more because of my experiences with youtube navigation than because of owt else. Edit: then again, I can see why you might want to break this up. It is truly comprehensive.

[Emile]

Wonderful idea, I’d definitely watch that!

Don’t really have anything to add. Doesn’t seem like too much to me, and I’d watch it no matter if it was one or multiple videos.

[desolationjones]

Looks like a fantastic syllabus for course “101 Intro to d0” through course “304 Advanced Temporal Fuckery”. A few thoughts:

• You could use John’s Zoom web demo app to give a graphical example of Zoom.

• External mixing is critical to d0. Perhaps choose a very visible mixer (e.g. MI Blinds) and keep it in frame, with unique colored cables for inputs/outputs/mixes.

• Demonstration of saving/loading module state using Select Bus i.e. MIDI CC16 on the CV bus?

• I have never fed the tuning signal back into input A for calibration (has anybody?). Curious about this one…

[smbols]

Good thoughts, thank you!

Definitely going to touch on the necessity of an external mixer in the overview portion, as well as having a low pass filter. I’m planning to have the d0 mounted beside a matrix mixer since that will be quickest to show all the varieties of routing. Do you think it would be helpful to include examples with a more basic mixer, too?

And I regret to say, I’ve never gotten around to actually using the MIDI save/load/tracking features on my module. I have a MIDI adapter that I got along with it, but I just never ended up mounting it to a panel and using it. I might be able to get that working for the demo, but if not, would someone be willing to film a quick example of that and I can edit it into the rest of the video?

Also curious to hear if anybody’s actually used the calibration feature. I forgot that was even a thing
