Are products such as this suitable as an external oscilloscope for a eurorack system?

Hantek 2C42 Handheld Oscilloscope Multimeter 2 in 1 Multifunction Tester 2CH+DMM 40MHz Scope:

I'm really unclear on if I can run a patch cable directly from one of my modules into this device. I'm also not sure if this oscilloscope works with DC signals. It says the multimeter is DC, but nothing about the oscilloscope.

I'm looking for something on par with a Zeroscope in terms of:

  • View two signals at once
  • A grid with the option to see where +/-10V is, and ideally +/-5V too
  • Support for audio and DC signals

Any recommendations? Or am I really better off using a module with an oscilloscope designed for eurorack?

Tangentially: I have no multimeter and I'm thinking that would be useful for testing hardware for issues, recalibrations, and building DIY modules. But I see I can get a dedicated multimeter for a tenth the price.

generally you'd want to get 3.5mm to bnc cables - but this oscilloscope doesn't seem to support them - possibly better searching for scopes that are recommended for eurorack users (try searching on modwiggler!)

I'd probably look around based on those (they'll probably be a little bit more expensive though - unless you can find a slightly older module used...

I just use a cheap multimeter for checking my DIY builds...

personally I'd go for a expert sleepers interface (which I have) and use one of the scopes in vcvrack if I needed it - never have though...

Utility modules are the inexpensive, dull polish that makes the expensive, shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities

I can recommend what I use currently, but as in all things, what I like may or may not be what you like or even find useful. I suggest you check out some reviews and proceed from there.

With that said, If you're going to buy an oscilloscope, save a little more and get a good one.

As for the multimeter, I own super expensive Flukes, but I end up using this rather cheap one a lot.

If you want a few more options, pick up the leads kit.

edit: here is the case I use for the DM6000, all of the leads including the extra kit, fit in the side pocket.

Here is the interface you may be looking for. And the DIY version.

Naaaah...what you need, if you're getting an external scope, is one that can ALSO be used in an X-Y mode. If you're doing a lot of bassheavy stuff, keeping an eye on low end phasing is a MUST, and a dual-tracer in X-Y can give you phasescope results when you connect the two stereo channels to the two inputs on the scope. Why? Well, if you're tracking for vinyl, you'll find that bass signals below somewhere around 120-180 Hz can cause SERIOUS problems for the lathe engineer. So as a rule, bass below that certain point can cause havoc if it's out of phase, so it gets summed down to mono for vinyl. Keeping an eye on phasing while mixing, also, helps you get to better mixes with some practice, especially when doing a lot of panning and other screwy imaging processes.

FYI, eBay has a pile of suitable o-scopes for $200 and down...just make sure that you get one that's dual-trace with X-Y capabilities.

I'm not really sure why you would buy a scope to do what is essential mixing/MASTERING. And better accomplished in a DAW - be it Ableton, Studio One, Pro Tools (insert any modern DAW here), or the free-to-use Reaper.

I personally use FabFilter Pro stuff for work, but every DAW including Reaper has everything you need to master a track with plugins to handle anything from streaming to vinyl.

If you want some good information on mastering, Dan Worrall's channel is a good place to start.

Again, I'd do some research and check reviews before proceeding -end of line.

I should have given more context. That's not what I'm doing.

The scope is mostly used for looking at DC/modulation signals. When I'm trying to finesse a modulation signal with an attenuation and offset, for example. Or when I get new modulation modules, helping me understand exactly what they are doing so I can figure out how to use them best. It's for testing signal flows within my patch when things aren't working as expected.

I guess I approach patching like software programming and the CV scope is my debugger. Although I sometimes mindlessly experiment, I often have a specific idea that I'm trying to pursue and sometimes I need to see what's going on to make it happen. To give a specific example: One thing I like doing lately is feeding an LFO into a waveshaper and then into a clock-triggered quantizer. It's really helpful to see what's going on there while looking for the "sweet spots".

Asking about external scope options comes from the fact that I have a Zeroscope 1U and it is very useful to me for these purposes, but I only use it when I need it which is not most patches, so I want to swap it out for more "day to day" utilities.

I know the correct solution here is to get a bigger/second case and keep using the Zeroscope, but I was wondering if there's an affordable external option that could be useful for other purposes, such as in DIY contexts. I was also just curious how you connect a modular system to a general-purpose scope. It wasn't obvious. Thanks for pointing me to

I like this suggestion:

If I can get a DC signal into my computer then I can do whatever I want with it. It probably makes more sense for me than buying dedicated hardware. I'm not sure I'm equipped to do that at the moment, but I'm going to keep this option in mind.

Well, you do see an awful lot of them in mastering transfer desks back home..."back home" being Nashville.

The main check for it is to see if there's anything that's so out of phase in the low end that the engineer needs to go back and perform some bass summing to correct that...before it either 1) wrecks the cutter head, or 2) cuts a lacquer that's unplayable. Now, for digital, it might seem that an o-scope isn't useful, but I also use mine when doing various stereo manipulation methods (like expanding the stereo field beyond the L-R between the monitors) and to check if there's something that's creating a spatial "lump" that needs correction so that the stereo field can feel properly centered. Mastering really is something of a "black art", though...the sessions where I did some of that while learning were a revelation in RElearning how mastering sessions work and what's essential for them, coz classroom teaching and/or textbooks will only get you so far.

But if I've got my ears, why do I need the scope? Well...your ears are only going to sort out the basic stuff if you're juggling 15-20 channels, so the scope provides a second visual check. If you see a problem, go back to that timestamp and fix it. Simple.

Do yourself a favour and thet a Mordax Data instead of fiddling with some external thing, adapters, settings...
BEst purchase i have ever done, thinking about a second.

That's a good call out. I was vaguely aware of this module's existence, but it wasn't really on my radar. Based on my previous comment, I'm in the target audience of this module. I can see myself getting use out of a quad scope (like looking at I/O from a logic module), and waveform generators and clock dividers are always useful. It's going on my wishlist!

Love my Mordax Data and the developer responds to questions. I want another one for my other case.

Awesome! That's exactly the kind of thing I was hoping existed when I started this thread. I'm keeping an eye on that one! The Mordax Data still sounds like a great option but it's a bit of a commitment at 16HP.

Very, very odd. Typical Volca users won't get much out of this, so it's confusing as to why the NT-1's followup is an o-scope. Not saying it's not useful, mind you...just odd.

Could it possibly be...a LIMITED EDITION from Korg? Only 100,000 units made! Comes in its own road case made from recycled Pringle's cans! Secret product leaks from Yanni!

Frankly, if Korg wanted to put out something useful that fits in with their other patchable gear (which actually doesn't fit in with anything, anyway...the MS-20(mini) uses linear CV scaling and negative gate/triggers akin to Moog's S-Trigger on their modules), they might consider a little box that contains all of the stuff they left off of the 2600M. You know...the stuff that Uli knew to leave IN the synth that was in the 3620 keyboard that...well...2600M users don't get.
