I have a stone age (last century) K2000 keyboard and recently aquired (on ebay) a K2000R rack unit that has comtemporary and orchestral ROM. One MIDI cable goes to the rack from the keyboard. I am running both audio outputs into a splitter and then to an amp. While I can control the rack nicely with the keyboard, I cannot change octaves from the rack independently from the keyboard. This despite trying different MIDI settings from both units. I find it odd that, for example, prog #122 BALLAD ORGAN is an octave lower on the keyboard than the rack. The soft buttons do work for other functions. Any suggestions would be appreciated. vasto
