There is certainly more to him than a composer of etudes and exercises, but he almost wrote too much for his own good.Several of his shorter works for piano and orchestra are delighful (Haydn Variations for instance), but on longer works, the high register tinkling wears a bit thin after a while and the inability to develop an interesting theme makes them less appealing that the shorter works.Herz, Kalkbrenner and Moscheles do it rather better whilst being cut from a similar cloth.
