Libraries and Sounds:

To create my music, I mostly use soundlibraries from developers such as:
Audiobro, Cinesamples, East West/Quantum Leap, Spitfire Audio, 8Dio, , Heavyocity, Orchestral Tools, Soundiron and some more.

I also use sounds from the Kontakt Factory Library and other VST’s from Native Instruments.

System Specs:
All Libraries and Sounds are stored on a 500GB SSD, everything else is on a 2TB SSHD.
My system runs Windows 10 Pro; 8GB RAM and an Intel Core i5-2500k.
I use Cubase Pro 9 as DAW and a Fatar Studiologic SL 990 Pro as my keyboard. Personally, I prefer working with headphones (Sennheiser HD650) when I record/write, and listen back to it later through speakers (some old but great sounding Dynaudio Junior).

Microphone: Audio Technica AT2020 for clarinet, cello or acoustic guitar.
