There are several library\'s out there designed for giga sampler [X sample , Quantum guitars , etc. ] that let you control variations of the patch from the bottom keys on your keyboard controller . My question is how can I access those lower expression keys if some of them are asigned below the range of my 76 note keyboard ? My controlled keyboard will only go up a 5th or go down a 5th . Im sure if i went down a 5th I could access those notes , but now the notes are out of key reference to other instruments that I might be using in my song . thanks for your time , Ken
