Subject: Re: How to move regions by samples
Message #225501
This is a reply to #225495.
Furthermore, a look at LUG member John Pitcairn's website www.opuslocus.com revealed the following... thanks, John: ------ That just leaves the option of manually moving the recorded audio. The Arrange window is not sample-accurate, so the only obvious way to do this is by moving the anchor point in the Sample Editor. Proceed as follows… To move an audio region by minus X samples: 1. Open the audio region in the Sample Editor. 2. Ensure the Sample Editor Edit >> Update Arrange Position menu is unchecked. 3. Move the region anchor point (not the region start point) to the right by X samples. 4. Close the Sample Editor. To move an audio region by plus X samples: 1. Open the audio region in the Sample Editor. 2. Ensure the Sample Editor Edit >> Update Arrange Position menu is checked. 3. Move the region anchor point (not the region start point) to the right by X samples. 4. Uncheck the Sample Editor Edit >> Update Arrange Position menu. 5. Move the region anchor point back where it was originally. OK, that's fine for single regions, but it’s a tad mouse-intensive (I suffer from RSI), and it’s a royal pain in the arse if you regularly record multitrack takes. There is another method — if you can record at an arbitrary tempo, use this formula to get the correct tempo for a 1-tick nudge which equals the required shift in samples: tempo = samplerate / (nudge x 16) For my Multiface, which needs a post-record nudge of -128 samples in OS X, at 44.1kHz that's: tempo = 44100 / (128 x 16) tempo = 44100 / 2048 tempo = 21.5332 bpm So at 21.5332 bpm, 1 tick = 128 samples. If I record at that tempo, then I can simply assign a key command to nudge -1 tick in the Arrange after recording. Multiples of that are probably a little more practical, ie record at 86.1328bpm and nudge -4 ticks. I have a list of the “magic” tempo multiples for my hardware in a marker in my Autoload. If your tempo is already set to something else and you have existing stuff in the Arrange, all is not lost. Record, then: 1. Select all (watch out for track-locked and hidden tracks) 2. SMPTE-lock. 3. Change the tempo to a multiple of the “magic” tempo you worked out. 4. Select only the newly recorded audio. 5. SMPTE-unlock. 6. Nudge. 7. SMPTE-lock. 8. Change the tempo back to the original tempo. 9. Select all. 10. SMPTE-unlock. If you have tempo-changes in the song, it's presumably the tempo at the region start that affects the nudge amount, so you'd just change that tempo while SMPTE-locked and leave the rest of the tempo-changes alone. I haven't tested this … Not exactly ideal, but if you can do it it's a lot quicker than opening each region from a multitrack take individually and moving the anchor point with the mouse (owww my wrist!)... -----
