Hello, I had a song that was recorded at 100 BPM which was imported into Logic at its default 120. In order to add MIDI drums and line everything up at the corrent speed, I performed the SMPTE lock procedure, slowed the time down to 100 BPM and unlocked SMPTE. Everything fine, locked the midi drums to this new speed and job done...until....I try to retune some vocals...using Flex Pitch...and the vocals automatically slow down and become out of time with the song. Thank goodness for 'undo'. How can I use Flex Pitch without this happening? Thankyou Neil.
