This is my second question for the day so please bear with me. I will give a break down of how I went about layering different midi recordings. 1. Tone: Grand piano, I made a recording for about 30 seconds. 2. Once I was done with the 'first recording' I pressed the record button again but this time I chose a different 'system track'. (Tone being drums now) I pressed onto the play button and the piano piece I recorded started to play and along this I started adding some beats. 3. I stopped and listened to the recording, the piano was playing along with the beats. And I found this to be great. The issue that I found out was that, when I transferred the 'midi recording (with the beats)' onto my pen-drive and tried to use it on my FL studio. The keys played for the beats were coming up as piano keys and the piano piece that I 'first (initially)' recorded doesn't even play. So I'm quite confused as to what I should do in order to layer piano keys and beats (basically different tones) and make it sound the same when I transfer it as a file. Please help me out. Thanks :))

Hi ! After I've made my recording on midi, and when I save (or transfer) it to my pen-drive , it gets saved as ".ZMF" Due to this, I cannot import this recorded midi file into the software I use as it requires a ".MID" and several other types which do not include the ".ZMF" Please provide assistance on how to overcome this issue Thank you :)) FIRST.ZMF
