I'm stuck. I've imported an SMF into a Song. This has rapid tempo increases towards the end.
I have added on an Audio track, a Voice Over .wav announcement timed to the music phrase.
The problem is the imported V/Over sample speeds up when the song tempo changes and sounds clipped and very silly.
How can I stop this and keep the Voice Over sample playing at the original constant length?

If you were to record a voice into the song from scratch you wouldn't get this "re-sampling" so what am I doing wrong?
Help please, I need this for a gig on Wednesday!

The work round would be to manually trigger a sample pad at the required moment, but for maximum impact the voice over end needs to come just a beat before a Brass stab - much easier if it's "built into" the song.
Any solutions?

Any "experts" that can explain/solve my problem?
I need to "lock" the length of the Voice Over .wav sample so that it's timing doesn't change with the tempo changes within the song. Is this possible?
I suppose I could try playing it in on the Line/USB input and re-recording it - but having "imported" it, why should I have to do that?
Thanks in advance.....

I think the best solution is what you suggested and resample it over USB input.

I'm guessing you are importing the audio onto the song which then gets tied to the clock of the song. Hence the speedup of the wav as the tempo increases.

You know all this already, so unless someone knows different it would be quicker to resample it than to post here about it

I also experimented this problem, but I found no solution
In my case, I essentially use the audio parts to record some voices (songs), but if there are any changes of the tempo, it produces many artefacts. For example, on a song called "La machine" (url http://www.jamendo.com/album/44945 ), there is a slowdown before the second verse. When I recorded this verse, I started the sampling on the last bar *before* the verse. The sample finally token as its original tempo the used during the verse, but applied a ridiculous slowdown on the first bar and so, of course, all the vocals were delayed.
As I founded no solution, I add to manually move the audio track to remove this delay (if you listen this song, you'll hear the breathing noise "splitted" by the time streaching process). When there are many tempo changes in one song, I now try to record small fragments on homogeneous tempo, but it takes a very long time, and it isn't always possible. I'd really like to find a solution to this problem, which seems "simple" because we only want the WAV to be played as it was recorded *without* time streaching.

Thank you for your replies.
I guess I'll go down the re-sampling via USB route.
It does seem to be another "snag" with the FG.
I seem to remember that you could "lock" the .wav's on Cubase.
Still, at least there is a workround!
..... And seamless Patch changing is worth any amount of discomfort!!!

I have tried using USB input - playing in the sample "live".
Guess what? The voice over still gets chopped about during the tempo change!!
I thought, perhaps 'cos it's USB, it's digital, and that's why it doesn't like it - so I redid it using the analogue input; Playing the song, dropping in at bar 7 and keying my voice over from Wavelab via the M-Audio FW410 analogue output to the FG8 Analogue Input........ Damn thing still glitches during the tempo change.
Mr ROLAND, HAVE I DISCOVERED A MAJOR PROBLEM?

I now have a real problem to solve before tomorrow night!!
HELP FROM GURUS APPRECIATED - Even if it's from Roland reps saying "Yes, this is a problem"!

Pick Roland answer:

[ ] It's a feature, not a bug.
[ ] It's not a problem, you're the problem!
[ ] It will be fixed "in the future". We can't say when, company policy.


Workaround:

Buy a mac + logic


/ wish it was sarcasm.

Edit: Forgot to say my Fantom G sometimes freezes/crashes when using the tempo changes with projects that have audio tracks (that are recorded with the fantom G).

I might have found a way to do what you want... Give me 10 mins to test this out.

I'm onto something.. can someone please clean my following instructions up for me please.. lol

1.. loaded the samples into memory and saved them to project.
2.. in "single" mode pressed pad mode and changed to sample pad.
3.. Pressed pad settings and set up my samples for each pad. Saved Patch.
4.. went to studio mode and created a new set. Selected "sample" for "type" on track 9 and selected the sample patch saved earlier.
5.. selected track 10 for drums and went and recorded a standard beat for 10 bars. Edited the tempo track to change from 120 to 160 on bar 5.
6.. selected track 9 again (sample) and hit record. Held the pad down to trigger the sample thru the 10 bars then stopped recording.

Played the song back. The drum track increased in speed at bar 5 the sample did not.

That gotta be able to do what you want.

Your method is better than just inserting the sample into the song- but in my case still unusable. In the song I go from Tempo 130 to 210 in just 3 bars and the glitches on the sample are just silly.
WORKROUND:
The "song" is just an intro to a medley and I take over "live" when the chorus singers start ( they can't keep sync with a track!!) So I need the seamless patch switching of the "live" mode for lots of patches during the 10 minute medley duration.
I have set up a Live set to "play out " my song and I have put the Voice Over on a Sample Pad. This does seem to work with no detectable glitches on the V/O.
However, because I was using all 8 tracks on the Song I didn't have a Part free for the Sample Pad, so I utilized "Skipback sampling" to mixdown the Horns and Trumpets onto 1 Part thus releasing a Sample Pad part.
Snag is, I now have to remember to "manually" trigger the V/O at Bar 7 for it to finish a beat before the Brass sting.

Any chance you can post the midi file or better still cut it down to about 15 seconds either side so that I can test it out here and see if it can be done ?

There's a small ajustment that you should try and that might help:
Check Sample Parameter and change the Time Stretch Type

hicko
I'm sorry if I missed something but I still don't get this: You say you now have to "manually trigger" the V/O. I assume you do that from the Pads. If that's the case you have 7 Patch parts and one Sample Pad part on the Live Setting, right? If so, why don't you just record the "trigger" on the song?

I think this wasn't too clear from Flumpster posts:
When you record or insert a sample on the Audio Tracks, the sample follows the Song Tempo and you can't "unlock" it from it afterwards. BUT you can assing the sample to a Drum Kit or Patch, get the Tempo Sync off and then trigger the sample as a Drum/Patch note on the sequencer. You just record a MIDI note that triggers the sample and you will get it playing without beeing locked to the Song's Tempo.

I did say my instructions were ropey.. Posted them very drunk one night.

I can't see why it shouldn't work either V-CeeOh ... all the test I did here that night worked flawlessly. I know I was using studio mode instead of live mode but that shouldn't make any difference that I am aware of.

Timestretching audio sounds horrible unless you stay within a 10-20% window. 130 BPM to 210 BPM will give you ugly artifacts with any realtime timestretch algorithm. For any type of transparency, you're looking at loading a custom REX file into Stylus RMX, which isn't true timestretching either—it's a combination of slicing, selective stretch algorithms dependent on source material, and tons and tons of CPU horsepower.
