Hi all,
Thanks for reporting this. We have not seen this bug in internal testing. @Shotglass does this happen only in certain songs, or all the time? The mp3 export uses Hookpad’s intrinsic playback to record into a file. Are you having any other playback issues on your machine? Do you get dropped notes when you export by measure instead of exporting the whole song?
One thing we can try is to expose WAV exporting as an additional option. This would be the same as mp3 export without the encoding step at the end, to help isolate the problem
