OK, i finally figured out exactly what was happening. I recorded a jazz piece in a global software (midi) piano instrument not knowing that it saved the chord progression i was using in every bar, so all the transpositions and intervals were saved- i then decided i didnt like my middle part, so i cut it out and thought i could just drag the 2nd half to connect with the beginning like one would merge or copy and paste in audio, however even though my notes were no longer there, the intervals i used in my notes were there and were saved and were effecting the new set of notes when i brought over the other section. Thats why all my notes sounded completely different.
Heres my question- is there a way to record in midi so that i can copy and paste like i do in audio. Is there a way to get rid of or not record with the interval/transposition recording every move? It seems like this limits a person, if they want to copy and paste. How do i record software instruments without having the transposition record going on at the same time? Thank you for your help.
