Music
 
I like to create electronic music, based on short loops. Most of the songs are created using a mobile software studio. Since 2004 I have used Phoenixstudio on Windows Mobile (created by the guy that made PPSSPP). In 2014 I moved to Caustic for Android and in 2018 to Korg Gadget for iOS. I liked Bhajisloops on the Palm too (made by the Muitable Instruments creator).
 

 
Manuals
 
I also love to create simple quickstart manuals for old synths I own. Preferably about functionality I could not find in the user manual NOR on the intertubes. The whole 'manuals' section has grown quite extensively into around 275 different pages on this website and even include a few home brewn web apps you can use for free.

Note: links to other websites in these manuals can break over time, I don't constantly check my links.
Please use the archive.org service to look for the (working) old version of these links.
This website only contains jpg, gif and (incidentally) png. No webp or heic files.

Apple iPad

I massively regret having invested so much money and time in Apple iPad Pro's and in musical software from the iPad App Store.
After losing my earpods, Apple decided to delete my Apple ID in june 2025, without any notice or warning.

This means:

• the iPads will be bricked after updating the iOS, because I have to re-login with my Apple ID after a reboot,
• the software and IAP's I bought will not receive any updates,
• iCloud is inaccessible, causing my library of documents that were not synchronised locally to be vanished,
• I will not be able to buy new software from the App Store.

This ended my relationship with Apple. My children will also not be buying anything Apple.
I also warn my students about this in my teaching classes.
I used to deploy iPads extensively during live performances, unfortunately my trust in Apple products is gone.
