I created a groove template and an audio-to-midi score in logic today in a song I worked on today (like, all day!) Now, when I load the song, it freezes after getting to the arrange window, and after a couple of seconds a small window saying "quantize" appears. Only way out is to cmd/alt/esc. I have control of transport functions for maybe 1 second. The last backup file was made yesterday, before doing the quantize stuff. Sent this feedback to Logic Pro bug report. Any ideas how to fix this? Tried renaming the file which was quantized but to no avail. Imac i7 quad core Snow Leopard 10.6.8 Logic pro 9.1.6 8gb ram Any advice would be greatly appreciated!
