Great samples @cleary! I was wondering about clicks in the samples until I realised your demo had cunningly added a pattern of clicks on top !
What have come to be known as the 'default' samples are of mixed and sometimes unknown provenance, and for a looong time it's been an aim to start again, with a decent set of CC licensed samples.
Here's a thread about it:
Basically I'm wondering if you'd be up for adding a bit of metadata in YAML or json that superdirt could understand, in a simple in extensible way? Then we could work on making them easily addable to SuperDirt via the quarks system or something like that.
