It seems almost impossible for me to choose between them all. Its an Aladdin's Cave of synth treasure! I am Loving the Cathotron and Altaerion - very creative manipulations of some classic sample sources. The Cathotron strings have refreshed my interest in the mellotron (which now sounds a little hackneyed in its original format). Pulstar is a Colossus of a Pad Machine. You are a real 'texturist', rare that one comes across a 'texturist'. YouKnow6 is the best Juno replacement I have come across, my Juno 60 is now unplugged!

i can be silent no more! The Hollow Sun folder on my sample drive is wearing out because i go to it more and more. The inventiveness of the Laboratory Machines are staggering and a true friend to creativity.

At Hollow Sun, you clearly understand that it is LIMITATIONS, not infinite versatility, that the artist sometimes needs to focus the muse. The Lab Machines are diabolical, clever, and strangely wonderful and unpredictable - they help me to "Re-experience innocence" at the keyboard, and have kick started dozens of fruitful ideas.

The detail and integrity of these instruments have cemented my relationship with Kontakt, and make me grateful to be a synth player in 2012.

We used Hollow Sun's excellent Vintage String Synths, VP330 and Crumar Performer samples on our interactive music iOS app Dimensions. The samples are extremely high quality and feel just like using the real thing.

Just a note to tell you how great the music lab synths are... great and inspiring. Really, really great work. i look forward to making music with these.

By the way, triosc and oscillisine work very nicely with my wind controller.

The Music Laboratory Machines make you feel like you snuck through a time
warp into some top secret 50's military installation and found a stash of
brilliant noise making machines constructed in an attempt to communicate with aliens, or to replicate their technology.

To say that these user interfaces are inspirational is an understatement, and ditto for what they generate of vintage oscillations. I also virtually got my old VP-330 back for next to nothing, as well as getting to "play the RMI" for the first
time, both authentic sounding and very playable. I'm looking forward to

LOVE your CP70! Instant nostalgia and you nailed it. Thank you Steve!

I really like the Radiophonica library, these are sounds that we're used to with Jean Michel Jarre but it's great for people who don't have access to those old goodies

Congratulations for the idea and the realisation of this original library, that I personally think can add an original touch in film soundrack. I'm impatient to come back to composing again when we're finished with touring to use these sounds in a 'real' composing situation on my next CD projects or soundtrack/video games composing.

I'm not normally one for contacting companies if I'm happy with something, being of the Stiff Brit' Brigade that thinks "you pays yer money" etc. Anyway, for some time, I've coveted the real VP330, even more so when a couple of years back, I was fortunate enough to have a play on one.

However, my covetousness has now been totally quelled as I've just purchased the VP330 pack and I have found it necessary to say how utterly pleased I am with it. In terms of usage, it's simple, it's straightforward and above all, it sounds absolutely amazing so expect to hear it on my next album!!!

They're really good.

Really well recorded..... Like them.

Using them on "Driver"..... we're working with James Lavelle on that so it's a goody!!

Rich Aitken - Producer

I'm a huge fan of the Hollow Sun libraries. Steve has a knack of sampling the instrument so that it sounds and feels as if you are playing the original. He also tends toward the eclectic and revels in the unusual, the Novachord for instance is like stepping into a Time Machine - some of the sounds are positively scary!

Fabulous products, very well thought out and instantly playable.

Chris Blackwell - Drummer, Composer

Just thought I'd drop you a line and say a big thank you. I mean a REALLY big thank you. I've spent the last month working all hours and going slightly insane doing a retro album for De Wolfe. I completed it today.

Your products gave me a new palette and a ton of inspiration which was greatly needed because I was struggling for a while. I used the Novachord and Vox alot - these products are amazing.

Again, many thanks.

Keep producing those great products!

Chris Salt - Soundtrack composer

What I like about your libraries is their subtlety - what I mean by this is that I get fed up of these libraries with megaton huge, over the top, bright & shimmery stuff - all very impressive from a superficial point of view but often not that playable.

I like the understated quality of these sounds - they play nice & can easily fit in a mix.

Ian Boddy - Composer, sound designer

Without these (Novachord) samples, AW's score would miss one very important layer, the touch of something that's been there for a long time, waiting for resurfacing. It's incredible what the patches can do, they fatten the sound up without taking space and cluttering the stereo image. I've recommended this library to practically everyone I've worked with.

Petri Alanko - Composer for Alan Wake

i'm JUST starting to write for the next 'postmarks' album, using your novachord, vox continental and crumar performer VERY heavily.

what amazes me about your sampling is how organic it is. It does not feel stiff and actually breathes. The Vox is amazing and the Crumar shimmers in a way that makes me have far less desire to crank up my real Solina.

your libraries are super super inspiring to me!!! ;)

again...thanks for all your continued sampling brilliance.

Christopher Moll - The Postmarks


"The Novachord character always shines through. From the moment you load the first of the 120 presets, it’s obvious that you’re playing a living, breathing instrument full of quirks and it’s these imperfections that bring everything to life. This library exudes warmth, a little grain and wheeziness, plus a dash of authentic hum, low-end rumble and background noise. The subtle tuning differences between notes as well as timbral and envelope variations constantly remind you that it’s 100 percent analogue ... you can almost smell the warm Bakelite and glowing tubes."

"This pack samples a refurbished Novachord from around 1940. Famous for its creepy pads, the original was designed by organ supremo Laurens Hammond. It's basically a 72-note polyphonic subtractive synthesiser, but of course, it's rammed full of valves rather than transistors. Hollow Sun have produced over 130 patches that capture the essence of the orginal. Terrific stuff!"

"Hollow sun's Steve Howell and Dan Wilson have done a stellar job re-creating the sounds of this vintage synth behemoth. The rich analog weirdness of the Novachord is expertly captured, and adds a great new element to every keyboardist/composer's sonic arsenal.

All the uniqueness of each analog circuit is captured..."

Since 1998, Hollow Sun has specialised in authentic recreations of vintage - and often rare - electrical and electronic musical instruments and other curios and obscura bringing these classic and innovative instruments (often wheezing and spluttering!) into the modern age. Hollow Sun is now drawing on several decades of experience to design and create our own unique synthesisers for Kontakt 4.



It has taken me less than expected, but after a little over a week of doing all sorts of things, I can say with confidence that Hollow Sun is back in business after a slight setback created by the EU and the new VAT regulations. The whole Hollow Sun product range has been migrated from Payloadz to FastSpring distribution service, and this brings a few changes in the way HS operates.

Firstly, some might notice prices will adjust according to their geological position. FastSpring requires stating the product price in USD and GBP. I did both - USD prices are slightly higher now (1 GBP = 2 USD), but this will bring the prices more in line with what Europeans pay for HS products + VAT now. Payment is still possible via credit card and PayPal. Use whatever you like better.

Secondly, you might notice I fumbled around slightly with Hollow Sun site. Mainly the menu bar on top. We now have a dedicated F.A.Q. section, and a dedicated Contact section - which now utilizes PHP form to send out support e-mails. This will hopefully reduce the amount of spam that has been coming to HS e-mails (mario/steve (at) hollowsun (dot) com).

Thirdly, a couple of products are now moved to Freepacks section (Stylophone and JayPea, as well as 2013 Spring Bank Special named as 'Big Synth') - these were too cheap to be economically viable when VAT is accounted for, plus FastSpring's per-order fee. There might be some more products that were previously specials for certain occasions showing up in the Freepacks section, so keep your eyes peeled!

And on the subject of e-mails, I would like to kindly request all Hollow Sun users to redirect their e-mail queries pertaining to Hollow Sun to either the new contact form on Contact page, or the newly created support e-mail (support (at) hollowsun (dot) com)! Steve's e-mail is likely to become phased out at some point, so there will be no replies from it when that point is reached. For the moment both Angela and myself are checking out the inbox of Steve's e-mail, but don't say I didn't warn you! :)

I believe that about wraps it up. I would like to shout out to mr. David Brenan who was a lion in helping me out with the migration to FastSpring. He uploaded all the products to their servers - my upload speed over here in Croatia is quite atrocious! Thanks, David - you're a legend!

Happy belated holidays, dear Hollow Sun supporters!

I would like to take a minute and explain some changes that will happen starting January 1st, 2015. First I'd like to apologize to Dan, Dan the Novachord man for shamelessly stealing his statement about the situation from his own Hideaway Studios newsletter. But he's a good chap so I'm sure he won't mind! :) So, here goes:

Due to fundamental changes in EU VAT legislation which come into play on January 1st, 2015, all B2C digital download service providers selling direct into the EU must charge VAT at the customer's local rate. The new "place of supply" directive affects very many world-wide online businesses including most sample library developers who sell and supply direct to the public over the internet. Frustratingly the new directive was very poorly publicised in the UK and left a tremendous number of smaller businesses unaware of the impending situation. To achieve direct compliance would require VAT registering in all 28 EU states posing a huge burden on small businesses due to a mountain of extra paperwork. For this reason Hollow Sun and several other independent sample library developers are in the process of migrating our payment and digital download facilities to fully compliant intermediary services. The migration and subsequent testing is likely to take a number of weeks to undertake and I regret that during this period the current purchase and shopping cart functions will be disabled from 1 Jan for customers from ALL regions.

Or, perhaps it's better to show this all with a picture (to the left - click on it for full size)!

For more info about all of this, please check this site if you're interested.

I apologize for any inconveniences caused by this, but we really need some time to make things work according to the regulations, and this will take some time. Note that the website with product information and demos is still going to remain online, but all "Add to Cart" links will be unavailable. Thank you for understanding and your unwavering support!


Here's to a successful 2015, everyone!

Hello, everybody!

Today, November 5th, is Steve's birthday and his daughter Alice's 18th birthday as well! A very sad and poignant day because he should be there to celebrate it with them... Steve always used to say that his daughter and him were twins separated by 39 years!

I would like to say that they both want you all to know that Hollow Sun will continue and develop as Steve would have wanted. Something is slowly brewing in HS Towers (currently residing in Croatia), and we'll see, perhaps as soon as next month we might have something new in store. Stay tuned!

Yours truly,

Greetings, Hollow Sun users.

Most of you have probably already witnessed the news on one of the music-related forum boards I posted. For those that did not, I am beyond sad to report that Stephen Howell, founder of Hollow Sun, unfortunately passed away on May 31st, 2014, in the early hours of the morning, at 56 years of age.

I was informed about this all by his daughter, Alice, and I've been in contact with her and Steve's wife, Angela, ever since. We have to figure out what will become of Hollow Sun from this point onward. It would not be the same without Steve, of course, but I am adamant about keeping his legacy in some way, if at all possible.

For now, all I can say is that Steve will be greatly missed, and that is an understatement. He went away far too soon.

There is a book of condolences set up by Rob Puricelli (a.k.a. Failed Muso), so please visit that site and pay your respects to the great man and the legacy he has left behind.

I will post any updates regarding Hollow Sun's future right here on this site, and on KvR Hollow Sun subforum.

Yours truly,

Mario Krušelj, a.k.a EvilDragon
