There seems to be a new way of doing PC keyboard as piano that at least two programs are now doing, with 2 1/2 octaves, and the black keys are diagonally positioned like on a real piano (see LMMS wiki under Piano Roll). This also requires use of the number key row since two rows are used for each octave. I couldn't find any info on remapping the "keyboard as piano" keys for OpenMPT. Please post how to edit the config file, or give me a hint where to start looking in the sourcecode, to provide remapping 1-0 and A-Z all to musical note entry.
