The composer calls the VSL library "a huge leap forward sound-wise, even though I still can't get it to work properly." He also uses the orchestral libraries of Peter Siedlaczek and of Miroslav Vitous ("great all-rounder, but a little too clean sometimes"), as well as Kirk Hunter's string library ("great sound, but very scrappy programming"). While these libraries are good enough for string and orchestral mock-ups in demos and for most film and TV work, Richter prefers to use real instruments on his albums. Similarly, few of the samples that make it onto his albums are canned. All outdoor environmental recordings on The Blue Notebooks are the real thing, recorded by him using DACS in-ear binaural mics.
