Short Overview

I recently tried out Melda's Multi-Analyzer after searching for a plugin that could show the frequency content of multiple tracks in one window. I was pleasantly surprised by how well it integrates with Bitwig Studio and how easy it is to use. Even though I usually find Melda's interfaces a bit clunky, this one feels straightforward and functional. With just a few clicks, I could analyze the frequencies of my melodies, leads, pads, and bass in one unified view. It's simple to set up colors and names that sync with Bitwig, and you get a wide range of options for adjusting the visuals, like averaging, smoothness, and range. Features like deharmonize for finding fundamentals, collision detection for overlapping frequencies, and visualizing dynamics, stereo placement, and even groupings make it a very complete analysis tool. The price was also a big plus for me, making it a great value for what it offers. Overall, it's become a very useful part of my workflow for mixing and arrangement decisions.

Introduction to Melda’s Multi-Analyzer

A few days ago, I was on the lookout for a plug-in that could display the frequency content of multiple tracks in a single device window. After some searching, I decided to try Melda’s Multi-Analyzer, primarily because it was on a substantial 55% discount, which brought the price down to just 27 dollars. The value was hard to ignore, and what drew me in most was its ability to show the frequency content of several tracks at the same time.

Initial Impressions and Integration with Bitwig Studio

I’ve known about Melda plug-ins for years but never really used them, partly because I’ve never been a fan of their GUI design. However, the Multi-Analyzer looked decent and felt straightforward to use. In Bitwig Studio, I simply dragged the plug-in onto my Melody bus and started exploring its features.

An immediate convenience is the “follow host name and color” function. If I turn this on and save the setting as the default preset, every new instance automatically follows the track's name and color from Bitwig. This synchronization is a small but very satisfying workflow improvement, especially when handling multiple tracks, as colors and names update in both the DAW and the plug-in.

Analyzing Multiple Tracks in One Window

To analyze various instruments, I simply drag additional instances of Multi-Analyzer onto other tracks. Each new instance automatically connects to the existing ones, and all their frequency curves appear together in one window. Assigning different track colors within Bitwig makes the visual separation clear and intuitive.

Main Features and Controls

Frequency Spectrum and Display

The main display shows the frequency spectrum for each track. I can adjust the averaging window (e.g., from 100 ms to 400 ms) to smooth the curves, making it easier to observe overall frequency content rather than fleeting spikes. Controls for smoothness and resolution allow me to tailor the visualization further, such as showing the dB range from -60 dB to 0 dB, or narrowing it if needed.

Slope and Normalization

The slope adjustment alters how frequency amplitudes are displayed, compensating for natural energy distribution in audio (e.g., pink noise reference at 3 dB per octave). Normalization is another important feature; turning it on maximizes the spectrum’s use of the display area, while turning it off shows the real amplitude relationships between elements like bass and melody.

Decay and Deharmonize Controls

The decay knob sets how quickly the display returns to zero after a signal falls silent, which is useful for viewing transients or sustained peaks.
More unique is the “deharmonize” control. This attempts to strip away the harmonics and leave only the fundamental frequencies, helping to identify the most important frequency components (such as the root note of a bassline). While not perfect, it can offer valuable insights into dominant frequencies.

Sonogram and Collision Detection

Switching to the sonogram tab provides a clear time-frequency visualization, which can highlight evolving elements like pads or sweeps. The collision tab is particularly powerful for mix analysis, it marks overlapping frequency ranges between tracks in red, helping identify areas where elements might clash and require EQ.

The plug-in also allows prioritization of tracks. For example, I can set the bass as the most important source so that it takes visual precedence in the collision analysis, which in turn helps me decide which supporting tracks should be EQ’d to avoid masking.

Loudness, Stereo Field and Oscilloscope

The loudness and waveform tabs let me monitor overall levels, observe dynamic shifts, and check LUFS values (momentary, short term, or integrated). I can solo or mute tracks within the analyzer to focus on specific elements.

The stereo field display shows panning and width for each track, highlighting positions in the stereo image. For example, bass is typically centered while melodies and effects may be spread wide. Monitoring here ensures no essential elements are lost or overlap in undesirable ways.

The oscilloscope is also included, with normalization and phase views, useful but somewhat niche in my workflow.

Advanced Features

Multi-Analyzer includes track grouping and the ability to hide or focus on select tracks, which helps declutter the interface in large sessions. There are overlays showing octave bands and instrument-specific ranges, useful for quickly identifying where drums, vocals, or other instruments typically sit in the spectrum.

Overall Experience and Value

For the current price, Multi-Analyzer offers a substantial toolset for frequency, phase, collision, and loudness analysis across multiple tracks in real time. The interface feels much more accessible than most other Melda plug-ins, and the integration with Bitwig Studio is impressively seamless, especially regarding track names and colors. Features like collision detection and prioritization make mix decisions much clearer and more informed.

Conclusion

Melda’s Multi-Analyzer has turned out to be a surprisingly essential tool in my workflow, and for the sale price, it feels like a must-have. Although I had reservations about Melda’s designs in the past, this particular plug-in is straightforward and powerful. If you work with complex mixes and want clear, actionable feedback about your frequency content, overlaps, and stereo placements, this plug-in is definitely worth considering.

[00:00:00] How great is actually Melda's Multi-Analyzer. So a few days ago
[00:00:04] I searched for some kind of plug-in that shows me the frequency content of multiple tracks in just one device, one plug-in window.
[00:00:13] And I settled down with Melda's Multi-Analyzer here because first and foremost, it's currently 55% off.
[00:00:20] So it's only 27 bucks for me, so it was kind of a no-brainer.
[00:00:24] And it does in fact show you actually the frequency content of multiple tracks in one device.
[00:00:30] And it also works very well together with Bitwig Studio.
[00:00:34] So I want to show you this here in this video because I know this plug-in for years, but I never really looked into it and never used it.
[00:00:43] And I also don't like mostly how Melda plug-ins look like or work like, so the GUI is not very, you know, pleasant to work with.
[00:00:52] But this one is okay in my opinion.
[00:00:55] So here in Bitwig we have multiple tracks and I want to analyze the frequency content.
[00:01:01] So here I just drag the plug-in onto this Melody bus.
[00:01:07] And the first interesting thing is I have here follow host name and color on.
[00:01:13] If you want to have this on all the time, you need to switch it on once and then you go to the device and say save as default preset.
[00:01:22] And now every time you load this device, this one is switched on, very simple.
[00:01:28] So it shows you here already the color purple as the frequency content, right?
[00:01:35] So this means if this is switched on, we can change here the color in Bitwig and the device or the plug-in tries to follow this color change.
[00:01:46] We can also change the name.
[00:01:48] We can say Melodies or Melody.
[00:01:53] You can see it changes here inside of the list.
[00:01:56] So when you change the name or the color inside of Bitwig, it also changes it inside of the device.
[00:02:03] It's very dope.
[00:02:05] Then all we have to do to see multiple frequency curves in one window is to drag in another instance here to the lead sound.
[00:02:15] You can see it's already connected to the other instance.
[00:02:19] So we can see two curves now just by dragging in another instance.
[00:02:24] So maybe change the color to green.
[00:02:27] The Melodies here are now in green and in brown you can see, yeah, that's the pad sound, I think.
[00:02:36] And then we need one more here for the bass.
[00:02:39] So we can see the bass in here.
[00:02:43] So we can close this and we can just open up one simple instance and we can see all the other instances here as a frequency curve inside of this device.
[00:02:53] And you can see the GUI is not that bad.
[00:02:56] It's very straightforward.
[00:02:57] The biggest thing is here the frequency content and the rest of the stuff is kind of in your range.
[00:03:05] So what we can do now with this is we can first and foremost change here the averaging window from 100 milliseconds to maybe 400.
[00:03:14] You can see it's now a bit smoother here.
[00:03:17] It's kind of an RMS value of these curves.
[00:03:21] We can also change here the smoothness if you want to see it more clearly what's going on.
[00:03:31] We also can change the resolution in terms of dB range here.
[00:03:36] It goes from -60 dB to 0 dB which is maybe too much.
[00:03:40] So we can say let's go to a 30 dB and it cuts off all the rest.
[00:03:47] Let's maybe go back to 60 dB here.
[00:03:51] Then we have gain should be pretty clear.
[00:03:54] We have a slope so we can change the weighting of the visuals here.
[00:03:58] It's actually a 3 dB per octave which is kind of a pink noise, a pink noise curve.
[00:04:03] You can also go back to 0 which is I guess white noise.
[00:04:08] And then we can also go to 4.5 which is bass noise.
[00:04:14] And also here you can see the bass is always at 0 dB.
[00:04:18] That's because we have normalization on so we can switch this off.
[00:04:21] You can see the real peak value here of the bass.
[00:04:25] But sometimes it's good to have normalization on so you use basically the whole area here of this GUI.
[00:04:35] So you can use it if you want to.
[00:04:38] So that's the slope.
[00:04:39] We have also your decay. I don't know really what this one does.
[00:04:43] Maybe I look here into the help.
[00:04:47] Let's see. Decay controls the speed that the magnitude returns to the minimum value, silence.
[00:04:53] So it's kind of how the visuals go back to 0 after some time.
[00:04:59] But more interesting is here the deharmonize knob tries to remove harmonics in the content and leave only fundamentals.
[00:05:08] This may help you find the dominant frequencies in the signal.
[00:05:11] So that's pretty interesting.
[00:05:13] So let's bring up the smoothness here a bit more.
[00:05:18] Let's say you have your frequency content.
[00:05:20] You can see this is the bass and the bass has also overtones.
[00:05:24] So maybe let's disable this here.
[00:05:26] So the bass has some overtones.
[00:05:30] So you can remove the overtones now here with this.
[00:05:33] And it tries to find only the prominent, the most important or lowest frequency in the signal.
[00:05:40] And that's pretty much your fundamental, I guess.
[00:05:46] It doesn't look right to me actually.
[00:05:49] There's probably a lot of rumble down there.
[00:05:51] Maybe you switch on here the reverb.
[00:05:54] The drone sound here.
[00:05:58] Try to deharmonize.
[00:06:02] Probably here your fundamental.
[00:06:04] And then you can do something like show you the peaks.
[00:06:09] And increase your averaging window.
[00:06:12] You can see here more or less what kind of frequencies are peaking.
[00:06:17] That's D#3 of course.
[00:06:19] I'm playing in D# minor.
[00:06:22] So yeah, a lot of tools you can use to analyze the signal.
[00:06:28] Then there's here down these kind of tabs.
[00:06:31] These are also interesting because let's switch this off here for a moment.
[00:06:36] So this is the spectrum.
[00:06:38] Then there's the sonogram.
[00:06:40] We can also kind of do something here.
[00:06:45] Not really super resolution.
[00:06:47] It gives you kind of more clear visuals of what's going on.
[00:06:53] Then we have something like collisions.
[00:06:55] And you can see here where some frequencies are overlapping.
[00:06:59] This is in red.
[00:07:00] This is basically an additional lane in here.
[00:07:04] And you can also use here then on the left side these tracks to kind of prioritize certain things.
[00:07:11] So you can say the bass goes to the top because it's my most important track.
[00:07:18] I never want to cut something out of the bass.
[00:07:23] Maybe switch this off here for a moment.
[00:07:28] But kind of the reverb thing, the lush reverb lead thing, which is kind of a drone sound in the background.
[00:07:35] That's something I want to EQ something away because I want to make room for more important instruments.
[00:07:42] So this is where you can change the prioritization here of this.
[00:07:48] And I think it should change here how it looks like down here.
[00:07:55] And then you can decide where you want to make cuts in your instruments.
[00:08:00] Yeah, I kind of find it interesting to have this.
[00:08:03] Then there's something like loudness and wave.
[00:08:06] And you can see here some kind of, yeah, how it's called the wave form.
[00:08:12] We can also disable here the bass and only look for certain wave forms.
[00:08:19] Here there's the bass and then the melody on top and you can see the loudness here over time.
[00:08:23] And this is the momentary loves value that you can see here in blue.
[00:08:28] We can also use short term or integrated.
[00:08:32] So everything is in there and you can compare and you can see where the dynamics go too much or too low or too high.
[00:08:41] You can also stop this.
[00:08:44] What's this here? I have no idea.
[00:08:48] Okay, so this is stereo here, the stereo field.
[00:08:51] Of course, the bass is completely mono in the center.
[00:08:54] Melodies are pretty wide.
[00:08:57] I have here also a panning modulation left and right and the drone on top.
[00:09:02] So you can make decisions based on this.
[00:09:06] You can see, oh, there's a lot of stuff happening on the sides.
[00:09:09] Or maybe the bass is too wide or whatever.
[00:09:12] And you can really pinpoint or focus on certain areas.
[00:09:17] Put the clap on this position at the stereo field or, you know, the percussion is on this position at the stereo field.
[00:09:24] So you can see this all in here and you can see it's all over the place for me.
[00:09:28] And it's actually, it sounds cool to me because I want to have this kind of soup, this reverb soup.
[00:09:35] Yeah, but you can analyze it if you want to.
[00:09:38] Then there's of course here an oscilloscope, also a normalization is also in there.
[00:09:43] You can remove the bass. That's the bass only.
[00:09:47] That's the melodies. That's the drone sound on top.
[00:09:52] Not really helpful, I would say, but maybe you can see here the face, face correlation with certain instruments.
[00:10:00] Yeah, you can do it.
[00:10:02] So it's everything is in this plug-in and there's much more.
[00:10:07] It's not just that, but these are the things I use mostly.
[00:10:12] You can also create your groups on the left side.
[00:10:15] Put these in groups and then just hide certain things.
[00:10:20] There are some overlays here. You can use octaves.
[00:10:23] You can see this the first octave, second octave, or maybe overlay this here with drums.
[00:10:28] You can see here is usually the snare drum, snare punch.
[00:10:32] I don't know if you want to use this or if you need this. It's in here.
[00:10:37] Vocal females, female vocals, saxophone, growl, bite.
[00:10:45] Okay, it's maybe interesting.
[00:10:48] So everything is in there.
[00:10:50] It's, in my opinion, a really great plug-in for this price at the moment for 27 bucks.
[00:10:55] I mean, it's absolutely a no-brainer.
[00:10:58] By the way, this video is not sponsored or anything like this.
