Thank you for the info. I am certainly no beginner to midi, having used many components combined live for 30 years (e.g. 2 keyboards with 4 zones in total, bass pedal, Roland Integra plus BK-7m) and done a lot of sequencer work with Cakewalk Sonar, however this specific problem of having no reaction to key velocity has never come up. So I‘ll be trying to find something under the links you provided.
