dreamer sorry of course I wrong write because fast
of course ".ins" is from ketron. but is not like you talk cakewalk extension, it is particular audio format
I talk along with ketron. maybe they do only for copy protection, I don't know, but is true that with only software we cannot modify or create .ins file from wav ecc
we need software plus hardware.
the only way is that they expand the msp mode, for add stereo files, more layer ecc (the actualy msm sampler is very bad, with only mono wavs, no layer ecc)
the delplian always so big then reality
