Scrubbing Bug
Uncommanded rapid auto-replay during scrubbing

Reaper v3.104
Intel Board
P4, 2.0 ghz
2 gb RAM
Total tracks recorded: 9

Recorded several tracks from vinyl and was scrubbing right to set a marker for the next track (#10). As I neared the end of the previous recording track (#9)the complete track began playing back at rapid speed (like a 33rpm played back at 78rpm). The only way I could stop it was to close Reaper without Saving. Of course, re-opening Reaper I had to re-record the track all over again.
I tried this several times, always with the same result. The last time I recorded the track, I Saved and Closed the project before continuing so I had a completed track before opening the project. This seemed to correct the issue, until I repeated the same functions. As long as I Save, Close, then Re-open the same project before proceeding to the next track I have no further problems.

This is while the recording was in process? You shouldn't be able to scrub audio while recording, do you mean scrub or just moving the edit cursor ahead to drop a marker? How exactly were you moving the edit cursor?

Glad you asked for the clarification.
During playback was tapping the Right Arrow key to move the line forward to set another marker.

Sorry, still not clear: this is while recording or while playing back? (You say "during playback" but then you say you had to re-record the track...) Thanks.

... either way, I can't reproduce it. Could you give a more specific step-by-step of how to reproduce?

OK, and Apologies for not being clearer.
1. Several separate tracks recorded, a marker for each placed at the beginning of the track. Last recorded track does not have a marker placed yet.
2. While stopped (No Record, No Playback)placed Edit Cursor near the end of the last track, then using the right arrow key slowly moved Edit Cursor to end of previously recorded track, as I wanted the very end of the track to be my starting point for the next recorded track.
3. Just before reaching end of previously recorded track (moving the Edit Cursor to the right)it would start un-commanded high-speed playback of the track.
4. I was only able to stop it by closing and re-opening Reaper. When closing I did not Save due to fears I would be saving a problem.
5. Unless the previously recorded track was saved *prior* to moving the Edit Cursor, the previously recorded track would be lost (See #4, above).

I've repeated this at least 6 times with the same result, but noted that if I use the Right Arrow key *very* slowly, the problem does not occur. by "very slowly, I mean one tap every 1-2 seconds. I used this method to complete the project.

I originally posted this in another forum (because I wasn't sure if it was Operator Error, Machine Issue, or Bug) but was referred to Bug Tracking. It could well be Operator Error, since I'm a fair newb to Reaper, but I won't know without help.

Not sure how much clearer I can be at this point. Should you need any more info please don't hesitate to ask. I really do appreciate the effort put into Reaper and am amazed at the support available! PT never treated me this well!

That's clear, thanks.

The part that confused me was the "lost recording." If you have a recorded item in a project, that recording is on disk somewhere. If the project is closed without being saved, the project won't contain the recording when it's reopened, but that recording is still on disk next to all the other recordings, you don't need to re-record it.

In any case, we'll do our best to reproduce.

Would you mind emailing the project (in the state where scrubbing forward will cause playback to start) to support at cockos dot com?

A day late on that one. Once I finally completed it and burned to CD, I trashed the project, emptied Recycle, and Defragged the disk. Never thought you might want it.

After listening to same project in my vehicle I noted "burps" in one of the tracks. Looks like I'll be re-creating the project anyway, so if the problem re-occurs, I'll forward to you.

If it does *not* re-occur, I'll assume it was operator error of some sort and relieve you of any further time possibly wasted on this.

Labor Day Weekend. Given the day off. :-) Here's what I'm experiencing today while re-creating the project.

Project: Record Vinyl album "McGuinn, Clark, & Hillman" to CD

Setup: - Four Tracks recorded, Markers already set for #1 thru #4. - Setting up marker for track #5 prior to recording said track. - Currently in STOP mode.

Symptom(s): If cursor is set inside of track #4 near end (Approx. timeline 13:53:500), then scrolled Right using Right arrow key, uncommanded high-speed playback of track #4 occurs.

NEW: Clicking the Transport STOP button stops high-speed playback (This is good, as it didn't before). This behavior also occurs when identical steps are repeated in any other tracks.
NEW: Noted that once the uncommanded high-speed playback is stopped with the Transport, the problem does not occur again on previously recorded tracks.
NEW: When moving the cursor with the arrow keys prior to setting the Marker, as long as I scroll *first* with the LEFT key, *then* use the right key, the problem never occurs in the first place.
NEW: As long as I place my cursor *after* the end of the last recorded track, then move it with the LEFT arrow key only, the problem does not occur.

Do you need the project (.rpp) file and supporting .wav files (there are eight files)?

Here is the zipped project.

Upload failed. Trying again.

No go. Got this message:

If it's too big or troublesome to upload, you can email the proj to support at cockos dot com (please note that it's about http://forum.cockos.com/project.php?issueid=1101).

.zip file sent via e-mail.

Thanks for looking into this.

Also uploaded to stashbox:


Tracks shortened considerably to allow for e-mail and upload. Problem still occurs.

If no one else can duplicate this, I can only assume I'm:
a)crazy (we often have repetitive hallucinations),
b)stoned (left-over tracers from the good ol' days), or
c)stupid (need to go back and read the.pdf).

I'll accept the majority vote. ;-)

Could you please post a screenshot of the Preference's "Playback" page and also which OS you're running?
I can't reproduce yet on XP32bit but don't want to hit the "cannot reproduce" button this early. Does this happen at any zoom? (the scrubbing speed is zoom dependant, why I ask)
09-13-2009 08:35 PM

Screenie of Preferences>Playback and Project window at my working zoom level.
