In 1985 he was cofounder of the Cologne-based Thürmchen Verlag (Publishing House). He has received several major composition awards including the first prize in the Stuttgart Composition Competition (1991), the 13th Irino Prize for Orchestra (Japan, 1992), in 1995 the first prize in the competition »Vienna modern«, the Hindemith Award of the Schleswig-Holstein Festival and from the state of North Rhine-Westphalia the award for most promising in the category music. In 1988, he was awarded the same by the City of Cologne. He received a scholarship in 1995/96 at the Künstlerhof Schreyahn (Artists' Colony), Lower Saxony, and in 1998 he has been granted a fellowship to carry out his work at the Villa Massimo in Rome. He has represented the young generation of Cologne musicians in exchange projects sponsored by the Goethe Institute in New York (1989) and Atlanta (1993).

His interests as an interpreter - he is cellist in the Thürmchen Ensemble, which he also co-founded in 1991 - are focused primarily on young composers from the areas of experimental music and musical theatre. Caspar Johannes Walter's works are performed regularly, not only in Europe but also very successfully in the USA and Japan, for example 1993 World Premieres in Atlanta and Tokyo.
