Great, I am very happy that this is finally out of the door.

Here is a video playlist with all my audio demos bounced to video, so you can see Groove Agent in action while listening:

It took me about half a year to accomplish, over 1.700 samples and loops were played and recorded all by myself, cut, edited, polished, also transformed into electronic soundscapes and other funny noises and eventually structured in musical patterns and loops.

You will find deeply multi-sampled sounds of:
darabuka, frame drum, ocean drum, concert toms, various snares, djembes, various chimes, gong/tam tam, a kit made from door sounds, a kit made from field recordings recorded in various factories, container drums (aste and charity containers), electronic drums, singing bowls, kitchen percussion, hang percussion, Angkelungs (chromatically sampled - 18 sizes), crotales (beaten and also some bowed sounds), 200 litre oil barrel, corpus percussion (played on a cello corpus and some other stuff), cymbals (ride and various splashs), water pan, rainmaker(s), Nepalese bells and finger cymbals, temple blocks and warped drums sounds and some spring drums too.

This makes my day…

P.S.: More infos and detailed descriptions of each kit can be found in this thread on my patchpool forum:

Pretty cool stuff. Sounds like the Metronomic Cinema expansion would be a great companion to this.

Very nice, Simon. Bought it - like it!

Thank you, Ed!

Very impressing sounds and tones!

Hello, I would like to use the sounds in different pitches for example Pitch 432.

Is there a way to adjust the pitch exactly?

Thanks and Regards, Robin

Wonderful Sounds!

I would like to use the sounds together with analog instruments in different pitches

  • a Shruti Box in pitch 432
  • a stone flute about Pitch 436
  • wooden flutes I have

Are the pitches under control, can I write a number there? Or how exact are the sounds tunable?

Thanks and regards

however I just purchased it today and upon downloading the license, it stops half way telling me that there is a error downloading the license, and I need to either restart my computer or contact support… any ever had this issue…
also install the VST did it give you the option to select the Full version or the Trial Version?
any info would help with this


Please update your eLicenser Center and try to download the license again.

If you have purchased the set, just select full version. When you select Trial Version, a 30 day trial license will be installed on your system.

As I already replied to you on youtube, each sample can be fine tuned within a pad (cent control) and there is an overall tuning control for each kit, so for all chromatic sounds which are referenced to 440 Hz and other samples with a clearly defined pitch, this makes sense.

Hello, I tried some sounds in Groove - Agent. Don’t have a pad but a a pitch control looking like a shift and i shoved it to 431.8

For my use at the moment thats good enough.

But - Now I’ll upgrade to Artist, maybe then its easier to have more Funktions / Help Funktions / Tutoriols, and maybe then I ll geht more knowledge and control about it.

Thanks a lot! Regards

Habe mir die Demos angehört und war begeistert von den Sounds.

Passen sehr gut zu einer geplanten Musik-Performance mit einem befreundeten Maler in einem Künstlerhaus in Lünen.

Habe mir Colliding Worlds heute heruntergeladen und installiert, auf mehreren Systemen, bzw. Festplatten unter Win 7 Prof./64bit. Leider ohne Erfolg. Die Einträge tauchen in GA4 auf, aber es werden keine Kits und keine Patterns geladen. Hoffe, dass das Problem bald zu lösen ist. Versuche es noch mal auf einem anderen Rechner unter Win7/32bit.

Wäre für Hilfe dankbar


OK! Hat sich erledigt mit dem Upgrade von GA4 auf 4.2


I just bought Colliding Worlds, Neuro Mindset and SOngwriter;s pack.
Unfortunately, after installing them I had to upgrade Groove Agent 4 to 4.2, and now the Metronomic Cinema and two other instrument sets are missing from the browser.
Any suggestion please?

Thank you

Great to see you here Simon, great library!

Having similar trouble - cant load any Colliding worlds stuff - I guess I need to upgrade to 4.2?

just purchased colliding worlds, love the sounds. Have not been able to access them in Groove Agent, only in Media Bay. Any help?
I just updated the Groove Agent to 4.2 and I’m happy again
