Berlin School

Imagine yourself in a cellar, filled with vintage synthesizers and analog sequencers, flashing lights, knobs and faders everywhere, playing Berlin School electronic music. If you don't have any of that equipment to your disposal, this library is the next best thing. It tries to bring some of that sound and feeling to your home and studio by supplying vintage arpeggio patches.

Awesome Sound Designer

CL-Projects produces great sounding libraries at a reasonable price. I own all of his stuff, but the OSA is my favorite for retro grooves. I highly recommend you check them out. Easy patches to work with and great sound out of the box.

OSA Arpèges vintage et modernes

Rien à redire, le titre explique tout
Il sonne vintage et moderne en même temps facile d'utilisation, simple et efficace.
Il est typé avec un son analogue et des textures de séquençage en couches évolutives, atmosphériques voir hypnotiques.
Pas fait pour les basses, mais tout le reste il sonne !
Bravo CL-Project
et Merci Kontakt Hub ****

A must have VST

I was a little reluctant to buy this VST because the price was so good when I listen to the demo it impressed me so much that I just simply clicked buy it now and for sure to my expectations the plug-in is amazing you have to buy it!

Excellent, varied classic arpeggiator patterns! Better sounding than other arpegiators included with DAWS.

Inspired by Tangerine Dream!!

Old School Arps that sound this great must be CL-Projects! Another hit from an incredible sound designer. I've had products like this that cost 3 times the price. Being a huge fan of Tangerine Dream, it's so awesome to find a Kontakt library that replicates the vintage Arps of these electronic masters.

Analog pulsing fun

This Kontakt library is just fun to play with.
Fat, pulsing, analog sounding sequences en masse.
Think Tangerine Dream, Autobahn and all these big players.
Play some chord progressions, improvise and don't forget to record your stuff. It's immediately usable for further track buiulding.

Old, New School

Like JMJ, Tangerine Dream, helped pioneer the motion-ed aspect of early 70s synthesis. These Arps featured are a great starting point, to put a bit of old and new together in the mix. The interface is clean as well.

Lots of retro pop fun

- A lot of fun to play and highly customisable
- Fantastic arps and one-shot plucks sounds (contains one shot, straight arps and triplets)
- 50 different sound sources to play with
- Lots of patches and multis included
- Nice price

- Bit of a one trick pony - but fantastic for synth pop songs or adding some old-school momentum to tracks

Just WOW!

Another really engaging collection from CLP! If you have a love for arpeggiated synths, this is the collection for you. The thing I'm finding about CLP's instruments is that they are full of really usable patches. No fluff here, this is stuff you can actually use without having to do too much dialing in. Although there is plenty to dial in on, if that's what you like. Great interface and cool sounds.

I have some other CLP instruments -- these guys really get it. Great work!
