Hi All, I'm experiencing cursor position, playback and rendering problems with SF6Beta and SF6. Has anyone else also had these issues? I've spoken to SF tech support - they wouldn't confirm or deny the problems but said that they might be releasing an update in June to address some "rendering issues". The problems are so bad that I've dropped back to SF5f (which is unfortunate, given the speed improvements in SF6). 1) Setting the cursor to anywhere other that time zero and pressing play results in variable delay between the cursor position and the audio that is actually being played. 2) Zooming in and out causes weird waveform display (the waveform often appears with gaps or concatenations of non-contiguous pieces of the audio) and again, the cursor position number (either time or sample) does not match with what is being displayed. Any comments, experiences??? Regards Michael Smithers |

you experience these problems with the final version? Build 132? What rendering problems...? |

Yes, build 132. By rendering, I mean the display of the waveform when you open a file. Basically what is displayed does not represent the waveform accurately. If you drop the cursor in at any location and press play, it doesn't play from where you think it will. This difference between where the cursor is displayed, and the actual play position varies, depending on how far from the start of the file that you originally placed the cursor. If you're interested, I can provide screen shots showing this and the zoom problems. Cheers, Michael |

Here's a link to a screen shot showing the zoom problem. http://www.michaelsmithers.com/sf6zoom.gif After zooming in, each shot (from the top down) is the result of hitting the "zoom out" button. Note that: 1) In the upper shots, the tail of the waveform is missing, 2) The cursor position number remains unchanged but the cursor position in each zoom is different.

Greetings, Have you found a solution to this problem? I am experiencing the EXACT same symptoms with my system. Most other functions that I've tried sofar with SF6 seem to work OK, but the cursor playback/zoom problem is really annoying, making SF6 virtually impossible to use. The cursor position does not track the waveform, making it impossible to view and edit with precision. When I open the same files in SF5, the cursor position and zoom functions work without problem. All the SF support pages indicate that the problem is with the sound card, but I've updated my drivers and the problem still exists. I'm not so sure it's a driver issue since mine are up-to-date and I can't seem to find any other settings/configurations to fix the problem. I'm running an Alienware 1.8MHz Pentium 4 with a SoundBlaster Audigy Platinum soundcard. I am currently experiencing no other problems with my system. Any suggestions? Thanks! (I'm new to the forum and appreciate the help) David |

I have the same problems. The only way the cursor position will be accurate is to play only 16bit .wav files. When I load 24bit, 48khz .wav files the cursor won't move at all and the meters jump out of sync but the sound is fine. I have an Athlon XP1800, 500mb memory, Windows 98se, SoundBlaster Audigy Platinum. |

If any of you were opening files as *.raw, there was a seek issue that will cause serious problems and will be fixed in the forthcoming 6.0b. Until then, saving to .wav and re-opening should circumvent the problem. We'll look into the other issues, but you might try increasing your playback buffering in prefs. |

I'm currently running 6.0a and this problem happens on both all files type, including *.raw and *.wav. I've tried opening at diffent bit depths and that hasn't seeme to make a difference. I'll try your suggestion regarding the playback buffers. The problem does not happen when I open the same files with SF5.0 (build 117). Thanks. |

Hi, Despite the RAW problem, there seem to be other problems with trusting the display and/or the cursor position. Here's an excerpt of correspondence I had with tech support regarding time aligning files!!!! Unfortunately I'm back to using SF5.0f Michael ------ I've been attempting to time align a number of mono WAV files by locating corresponding sample points in each wav file, and then adding or subtracting samples from the files until their waveforms are exactly aligned. What I'm finding is that each time I cut or paste the exact number of samples, the result is not correct (i.e. it can be out by a couple of samples) and so I have to repeat the process. Furthermore, when I load the aligned files back into Sound Forge 5.0f, the files are one or more samples out of alignment. Basically there appears to be a problem in the alignment of one or more of the following - the waveform display - the cursor sample number displayed below the waveform - the sample cut process So, once again, I'm back to using Sound Forge 5.0f....... |

Uh, let's try to simplify this. Would it be possible to come up with a simple scenario where one set of operations on the same file in 6.0 yields different results than 5.0? |
