As far as I have experienced, the d0 is simply the “most modular”, most precise delay in hardware. It’s small at 12 HP, but the d0’s simple structure means that you must bring a lot of other ingredients into the mix to achieve anything fancier than a clean single-tap delay. But that need to “roll it yourself” encourages exploration. I spend most of my d0 time building things that sound like boutique guitar pedals: dark flangers, crackly echoverbs, saturated dub echo swells, etc.

d0 starting kit: just add Zoom switch, Mutable Blinds, and instruo tanh :heart:

(“Why Blinds and not Veils?” Because feedback polarity makes a big tone difference: are you reinforcing a frequency or hollowing it out?)

I’d actually go for a Happy Nerving MIA as the must have module next to D0. It’s the perfect feedback utility along with some stackables.

I’ve had my d0 a few months and still can’t figure the bloody thing out :joy:

Personally I have a Instruo Tahn (for feedback loop tamming) and a small mixer (CP3) to get a copy of the original signal as well as the delayed one and it works a treat. The Tahn is highly recommended :slight_smile:

After a massive seller’s regret I repurchased a d0 / g0 combo and that’s what they look like now

Front panel and Functionalities are identical, but! There is a very interesting xpander port on both of them, don’t ask me I don’t know anything else. :slight_smile:

Revisions, rereleased modules are identifiable by inclusion of a DIP switch on the rear. The revised modules have changes as noted below:

d0: No functional changes or options. Power, +12V 80mA, -12V 25mA
g0: Tracking output and button are removed. Scaling of grain width is exponential, DIP switch A enables original proportional linear scaling. Power, +12V 80mA, -12V 25mA
p0: Additional models selected by DIP switches, A increases dispersion, B balances volume of components. Power, +12V 125mA, -12V 25mA

The zoom header no longer includes a MIDI connection. A MIDI adaptor is available that plugs directly into thebus board and connects through the 16 way power cable.

think of the d0 as a building block like a vca or a filter. what can you delay? everything!
you can delay cv, use it as phase shifter:


it’s easy to create phaser, flanger and chorus effects. it’s so clean you can use it as a sos looper.
delays in sub millisecond range are very uselful in any feedback patch. whenever you feed a signal back into the chain try to add the d0 inbetween. that doesn’t mean only physical modelling and karplus strong patches but also subtle feedbacks for drones etc. the d0 is probably the most used and most versatile module i have besides a function generator like dusg or maths. i also always think of mungo as a digital serge, you have to patch the function you want but it always is rewarding.

I finally got around to trying this out. The result doesn’t sound quite right to me, but it is definitely in the same ballpark as a fequency shifter. One of the ring modulators I’m working with though is a function generator that happens to have a ringmod function, but it invariably applies a slight distortion to the input, so that may explain why. Cool sounding result none the less!

The patch though is:

Dixie II sine > D0 A in
-multed to > Ring Mod #1 mod input
Dixie II square > D0 Clock

D0 A out > Ring Mod #2 mod input

Piano clip > Ring Mods #1 and #2 inputs

Ring Mod #1 out > Shakmat SumDif A in
Ring Mod #2 out > Shakmat SumDif B in

SumDif A+B out > monitor left
SumDif A-B out > monitor right

That sounds rad but I think you’re missing an ingredient for frequency shifting: the piano needs a 90-degree phase shift copy. My speculation was that the d0 could phase shift your source material by 90 degrees. The Dixie could be replaced by a quadrature VCO to free your d0 up for the task.

Excuse me for my simple question. I am interested in the D0 but am still trying to wrap my head around the zoom expander. I understand that it changes the domain of each of the knobs whether you press + or - but is this absolutely necessary? Can you address these really really small changes in delay offset with precision external cv?

#131

I consider it necessary. You could use external CV for that and always keep the d0 zoomed out, but that’s going to take a lot more hp and frustration than just adding the zoom switch.

#132

Thanks for the advice! my other thought was using Teletype CV outs to set offsets and store those in a script as presets. Doable? I know that’s not entirely as playable as the zoom expander but it had me thinking.

#133

I don’t have experience with Teletype, so I couldn’t say, but I feel like it would be a waste of resources. You could always try it out without the zoom switch and see if it works for you, and just pick one up later if it doesn’t.

The thing about the zoom switch is it really isn’t an expander. It’s a fundamental control, but the reason why it’s an additional module is that it is meant to control multiple Mungo modules at once. Say you have a D0, G0, and V0. That one zoom control gets chained to each of them, so you only have to worry about one switch to adjust the resolution of all three modules.

I’ve been getting a lot of noise from the c0 and I can’t remember if it’s always like that or if I’m screwing something up. I’ve been running it without the zoom switch (jumper set to ground) so maybe that’s involved. I know on the d0 it’s really easy to amplify the CV jack noise by accident but the attenuators on c0 don’t seem to be affecting the noise on the output.
(Summoning @kilchhofer, humbly)

#135

hm, sorry to hear that, but i’m not sure how to help. i would never run a mungo module without the zoom, so that’s the first thing i would check, attach zoom and adjust all controls to “default”. what kind of noise do you hear, what mode is the c0 in? the module in bbd mode has two ways to change the internal clock (eg the quality of the delay) one is the frequency tracking on the clock input and the other is the frequency offset control with it’s cv. the load button however acts in this mode as delay time adjust. so as with almost all mungo modules it is easy to get lost and have weird things on the output. it also has the same extreme slew limiter knob as with the d0, so be sure to have that set in a “normal” range, appr. 11 oclock!

#136

Convolution mode, not BBD. It manifests as a significantly higher noise floor of a frequency proportional to the c0’s frequency. I was mostly curious if you had experienced any noise like this; sounds like the answer is, “no.” After some thought, I am willing to bet the the c0 is amplifying noise from an upstream module. There’s a dirty NLC delay in the mix. I will patch a noise gate and see if that helps.

I’ll experiment today with adding the zoom switch back but I don’t know how that should affect it since my jumper essentially is just holding the switch in the “zoom out” position. In fact I am very confused because adjusting the attenuverters with nothing patched into CV is having a large effect on the pitch and gain, as if those inputs were normalized to DC offsets. I guess the attenuverters are effectively zoomed out, too, but I don’t know where the apparent offset is coming from.

#137

That sounds similar to how the D0 behaves, with the CV attenuvertors applying a slight amount of offset with nothing patched in. I always assumed it was a product of amplifying the noise present there, with the average voltage level increasing as the noise increases, making it seem like there’s an offset being changed. But that’s just a guess.

Have you tried patching a dummy cable into the CV inputs to see if the noise disappears? I’ll say that on my D0, when zoomed out, it’s extremely difficult to zero out the attenuvertors and the slightest nudge away from zero introduces quite a bit of noise that’s relative to the overall length of the delay buffer (more noise as the delay time increases).

#138

Sounds consistent with my observations. I tried a dummy cable and a cable patched to zero volts and there was no change in the CV attenuverter behavior. I was just going to set-and-forget the c0 for a show but I’m thinking maybe the zoom switch is mandatory even in that scenario.

#139

recently i had noise problems on channel a of my d0, the one with the built in amplifier, my input signal was very low and so i added alot of gain with the d0 and that amplified noise from all over the case. the c0 has also an enormous amount of gain with its amplifier so maybe the noise comes from there?

Has anyone here tried their Mungo modules in a video synthesis system? The fact that everything works and can be modulated up into the highest audio-rates, even into ultrasonic territory in the case of some of the oscillators, makes me wonder what that would be like.
