Lovely, ive been waiting for this.

oh wow, real time convolution of live audio, i don’t even know how that’s possible without massive latency … :dizzy_face:

You were right, I hadn’t read Navs’ description close enough and didn’t realize I needed cosines of both the carrier and modulator. I revisited the patch and got it working much better this time, doing the same basic thing but using Batumi’s quad LFO as the modulator and using the d0 on my carrier audio, multing the dry audio to a comparator and using that to clock the D0.

I have the downshift sent to the left and the upshift sent to the right. Half way through I start introducing some feedback. I was using a matrix mixer so I tried sending each ringmod result back into itself, and cross feeding them which produce slightly different results.

As a fun aside, I also found that clocking the D0 with the audio that it’s processing, and getting the slew and delay paramters right, makes a really nice warbly tape emulation with distortion that acts dynamically with the sound.

Sweet! Sounds like you got it.
There’s probably a comparator on the d0 clock input; did you need to use an external one so you could reject noise / harmonics? Higher threshold, or did you need more hysteresis?

#146

You know, I didn’t even try feeding the audio straight into the clock input but I’ll give it a shot some time soon. That’s just always what I’ve done when clocking the D0 with anything other than a pulse signal.

That demo @desolationjones posted probably explains a lot. It is extremely confusing, unfunctional and frustrating even with the visuals (if not more :))
I had an S0 which would probably be a great module for live processing (so I wonder if the g0 /d0 are actually nice) but the loading mechanism of the samples and the things you had to do to get to the live processing mode were extremely cumbersome. It is my opinion that he had to redesign these modules, unfortunately he didn’t and as far as I understand he didn’t even address the ESD issue which was quite suprising, seeing how many people ended up with expensive doorstops. It’s a shame but in my mind mungo is among a very small minority of manufacturers that although have an edge, and are probably knowledgable in their field, they are just too stubborn to realize and fix their mistakes. The zoom module is just a horrible engineering solution to a simple problem of setting two limits within a range.

Sounds like you have had some bad experiences recently. I think your Mungo opinion is shared by many but I can’t help feeling like it’s partially an issue of people not knowing what they are buying. John’s sparse documentation certainly doesn’t help with that! And despite the brilliance of the zoom function (IMHO), the Mungo UX is unarguably cumbersome. Maybe I’ll make a video tutorial for my c1 when it arrives next week.

AFAIK the ESD issues are only while handling bare modules. The truth is that most electronics are sensitive to ESD in this non-grounded state and eurorack users are just incredibly cavalier with their handling. If you create a 10kV potential across a sensitive component, that component is going to pass a lot of current. Watch anyone who builds electronics, PCs, etc. and you will see a lot of techniques meant to keep the human and the components at the same 0V potential. We should all be grounding ourselves safely when taking modules in / out of the rack… but who does?

No, not recently and no ESD issues thankfully (although there were quite a lot of incidents reported imo) but that demo triggered me. Tbh the demo seems more problematic than the actual thing, but it definitely does not make it easy to select a low and a high point, or at least a width and an offset. In the s0 you can only load a sample manually in a specific order, recording into the live buffer involves the zoom function and a removal of the sd card, keeping consistent pitch you need to take care that all of the samples have the same duration (and sampling rate obviously) and then you need to navigate within the sample using the zoom ranges… These are simply too many unnecessary quirks to work thru, especially in a live situation…

Fellow s0 user here. I traded g0 for it, so I have experience of both.
It was an unexpected length of time before I got so much as a sound out of s0. I understand what you mean about the potential awkwardness of it in a live situation, unelss one is comfortable with unpredictable outcomes. I’ve had a lot of fun using it as a granular texture synthesiser; in that regard, it really feels to me like a refinement of g0 (at the considerable cost of CV). G0 is definitely much easier to use for live bufffer processing.

I’m less troubled by the Mungo quirks; I don’t mind releasing the SD card to switch to live inputs, and zoom I find both easy and fun to use. With g0, the buffer can be frozen (for certain elastic and scrubbing sounds) only with a high-going edge coming in; as you know, s0 needs the same to trigger and maintain playback. Such dependencies on external connections for internal functions are a bit unusual in eurorack. But in the end I found them good fun. Rampage’s gate out, with the rise and fall sliders there on the panel, makes for a highly agreeable match for s0.

Nevertheless, I don’t expect to keep or at least use s0 much any longer, as I’ve turned my granular attention to Gotharman instead. C1 should be arriving tomorrow and I’m dead excited.

Hey Net, thanks for the input.
Yes that is what I thought about the g0 and perhaps the d0 as well,
they seem more straight forward, which would improve the zoom experience as well.
I chose the s0 because I always felt that granulation and granular synthesis work better for less abstract material (which is what I mostly get from the modular), unless you use them for droning and freezing of that material. So the idea of having identifiable samples (mostly field recordings then) and the granular processing was ideal for me. It just didn’t work, or perhaps I gave up too soon :).

. C1 seems to be a definite improvement on the c0! I am looking with interest tastychips ecr-1 as well, although no demos so far. Funny thing, I did my thesis many years ago on the use of I.R/convolution for extracting and adding identities (special and not) on abstract sound material, so although part of wants to get on these eurorack modules, I always have my max patches for that and suddenly the cost multiplies in my mind :slight_smile:

Some examples of the ECR-1 in action (not mine):

Are you in the US? Curious if you or ran into any delays or issues with post coming from AUS.

#154

the G0 has also seen a total refresh - no more wandering off into digital hash :slight_smile: Much much improved windowing, very very smooth ive been told

#155

My c1 is in the US after more than a month of sitting in Melbourne. So have patience, it looks like stuff is moving along but slowly!

I’m starting to wonder whether I’ve become a victim of ESD myself. S0 now appears to function normally, but there’s no audio coming out of the upper (sampler) section. LED feedback suggests that it loads the sample from the SD card, and the looper section is fine. But no sound whatsoever from that sampler. We’ve had a lot of dry air and static recently - I’ve had mini shocks even from touching the outside of the euro case. I haven’t been handling the PCBs directly, but the Intellijel shell is metal and so are the Mungo panels. Meh. Will keep testing.

EDIT: Lol never mind. I was zooming out instead of in when trying to load a sample. :no_mouth:

I received my c1 this morning. Although the live convolution does not disappoint, it’ll require some practice. The combination of several distinct features with the usual enormous value ranges makes for a lot of possible sounds.

Meanwhile BBD mode was instantly amazing, for instance entering ranges fine enough to give Autechre-like timbres. Very satisfying stuff.

Have had the D0, C0 and G0 in the past. Love these things but they are so difficult to work with. Have had the macro machines storage strip and the mungo zoom- I get the workflow, but still, always felt more like a science experiment than a tool to make music with.

#159

And here I am looking at the C1, :lying_face:

#160

cool! would love to hear a few live convolution examples!
i love the bbd mode on my c0 too, absolutely great delay!
