Simple and compellingly interesting. :yay:

Various harmonics and wave outputs are routed to A) delay>spring reverb (center channel), B) wavefolder/shaper (left channels), and C) straight to mixer (square out, right channel). Subtle FM from a Spectrum oscillator. Clock and modulation all driven by a Batumi. Only one envelope used.

This thing can do SO MUCH.

Great sounds from the harmonic oscillator. I have a Verbos system and plan on adding a harmonic oscillator sometime in the future.

Here's another, this time with a Voltage Multistage driving the melody (quantized with a Disting MkIII); the trills and runs are from switching two of the VMS stages from on to Glide. More patch notes in SC description. All those outputs...so many timbral possibilities for parallel effects processing...

Have you heard this?

https://www.youtube.com/watch?v=x4aH1HGzCUc&t=1125s

Don't know if this is true for this live-setup, but she said in an interview that the recent album is made with an Orthogonal Devices ER-101 and the HO as the only sound source.
Do you think there is additional waveshaping involved? Because a lot of the sounds don't sound very sine-y. From what I understand, you can synthesize all classical waves from different sines. As kind of a thought-exercise, how close to e.g. square wave do you come with the 8 harmonics?
Or should the harmonics on the HO be regarded more as a chord generator?

I'm new to modular world, building a medium sized rig atm.
Everything else is fine to choose for me, but with sound sources/vco's i'm having a super hard time deciding what could be right for me.

Here is a live modular performance you can see she is using a setup mostly made up of a Makenoise BG shared system with the HO and ER-101.

The harmonic oscillator has dedicated outputs for triangle square and saw waves.

A square wave is made up of odd harmonics. Here's an illustration of approximating a square wave with the first 4 odd harmonics.

Not to mention that self patching of harmonics outputs to other harmonics inputs create a HUGE different timbres.

Ah that's cool.
She's just talented with composition and could probably play a whole concert with a casio vl1.

But I'm buying a lot MN modules, they are so playable!
Also I really like the sound of the 0coasts sound generating section.

...

But I'm really interested in the HO. Do you think the HO is a good company for other VCOs like in the 0coast? I will probably replace it someday with 2STOs+Warps or a DPO.

Also I'm really into wavetable sounds and "pad"-capable synths in general.
I can't wait to see the new 4ms wavetable vco.
This and fear of complexity is mainly why I'm holding back on a Shapeshifter.

For something similar to the HO, the telharmonic looks interesting.
But I think I woulnd't enjoy the chord-based harmonization and it sounded a little too FFT-y from what I heard.
A square wave is made up of odd harmonics. Here's an illustration of approximating a square wave with the first 4 odd harmonics
At least this looks pretty close to a square. I think I'll fire up a MaxMSP patch soon to get a feeling of what's possible with this.
Regarding the saw/square outs: this is just a bonus, but has nothing to do with the sine-harmonics, right? So it's like a 3-shape VCO where one waveform can be designed to one's liking, with additional time-based control over the waveform.

I'm trying to get a grasp of what's possible there.
The sound examples in this thread sound pretty versatile, although I have to admit that I also get the "thinny" impression - coming from the 0-coast that is.

Here are some patch videos that are very Harmonic Oscillator driven if it can help you ;-)

Hey guys, I bought a mint HO and I seem to encounter an issue. The module does not scan through the 2nd harmonic. For instance, by setting the Spectrum Tilt at noon and Width fully CCW, you should successively light up each LED associated to each harmonics and hear each harmonic by turning the Scan/Center knob, right? By doing this, every harmonic can be heard besides the second one, no matter what I do... I tried on another HO and it seems to work as intended, i.e. the 2nd harmonic gets scanned through.

I'm kinda confused because it's the second time I'm using the module, and the first one was just a 45 second test of the function, I did not plug weird stuff in or out of it. Any advice? I contacted Mark, waiting for an answer...

This seem defenetly not normal. Mark and Sonya have been very responsive with me when i had problems with some of my modules so you should be sorted soon.

Using the Verbos HO for mallet percussion

Post by RLK » Mon Feb 05, 2018 8:14 am

Using the Verbos HO for mallet percussion:
Using racheting, then coupled with a triggered delay(to "humanize) and switch works pretty well.
Putting a quick decay on the CV input isn't critical, but it adds to the mallet impact transient effect.
Here's a sketch of mono or stereo versions:

After thinking back and forth whether I could justify the HP and money, I found such a bargain offer for a new HO that I simply had to buy it.

I only spent a few hours with it yet, but I'm super happy with the sound and playability. I went through the usual stages:
1 – "Wow, awesome sound!"
2 – "What the heck is the setting to adjust the harmonics with the sliders? Ah, there you go!"
3 – "Wait, these are not sines. Starting from the 3rd or 4th harmonic there's a strong crosstalk/bleed: sounds almost distorted. Oh no, my HO is broken!"
4 – "Reading on MW: No, it's just like that, all good!"

So for now there are only two quirks left:

A – There's only a tiny window for the Spectral Tilt setting (close to center), where I can adjust each harmonic with the sliders. If I turn the Spectral Tilt knob a little to the left I hear the fundamental, a little to the right the highest harmonic – even if all sliders are all way down.

B – Even with this "neutral" Spectral Tilt setting and all sliders all the way down I sometimes hear a tiny bit of one of the harmonics. I then have to gently push the according slider down again to get rid of it. And even then the harmonic might blend slowly in and out again: very quietly, but still audible.

I assume A is another case of "That's just how it is", but what about B? Is it normal or can/should it be (re)calibrated?

P. S.: Did I mention that I just LOVE the sound? :-)

Could anybody comment please? Is it normal that the sound of the "Mixed harmonics" out is changing over time – even when I don't touch any slider and don't CV anything?

Do you mean short-period fluttering variations, or gradual changes over time? If the former, then yes, I've experienced a little bit of this. It's not major, but the timbre's always subtly varying, in a way that sounds a bit more organic and alive (to abuse some cliches) than a rock-steady VCO: a sort of subtle animated growl. If the latter, then no, I've never noticed that. If you notice major, easily audible changes in timbre over time with no wiggling or modulation, then there might be something wrong.

Thanks, yes, I sent a video of the behaviour to the shop where I bought it and they confirmed that something's wrong, so I'll get a replacement. The problem only occured when the HO was running for some time (at least one hour), and it was most obvious with harmonic 5: it kicked in even when the slider was all the way down.

I bought a used HO couple of weeks ago and when I plug the square out to my disting mk4 for tuning, the display goes crazy like if I was feeding it a heavily modulated signal.

And it sounds "huge" like there is some kind of modulated drift.

Any idea?

Also, I use a Mantis case but the module is rather new so I assume there shouldn't be any issue, right?

Thanks

I've got the same problem, but with the 6th Harmonic. What was the key to getting a response from Verbos? Or was there an easy fix?

I'm thinking about buying a Harmonic Oscillator. I won't have very much room for modulators, and am considering the Intellijel quad AD, Doepfer quad AD, or the Verbos envelope. Any suggestions? I feel torn between the simplicity of ADs for transients versus having something more complex for sustained notes.

My 2 cents : it pairs well with another Verbos : the Voltage Multistage !

Sold this one over a year ago, and missed it ever since. Today I finally got a new HO. :bananaguitar:

The most soulful VCO, I've personally ever heard. And this unit tracks exceptionally well; way better than my old one.
