BPM issues with Samplitude Producer 11.5 and Samplitude Music Maker 2014

ShortBusMusic wrote on 11/23/2013, 1:06 PM

I have use Magix products for years and recently bought both Samplitude 11.5 Producer Edition and Samplitude Music Maker 2014 (both purchased because of the great virtual insturments).

I make a lot of loops for people.  When I record MIDI, I use an M-Audio Oxygen 49 and assign the virtual instruments with that controller.  When I finish with a loop, I can edit using the piano roll to make sure notes are all correct, etc.  Then I export the loop as a wav file and here is where the problem comes in.

Let's say I record a midi loop at 90 bpm using the Pop Brass vst.  I created the object using the "Open New MIDI object" tool (8 bars and tempo 90bpm using 16th notes).  I also made sure the VIP project was at 90bpm.  So everything looks and sounds great and all are at 90bpm.  I then export the loop as a wav file.  When I try to use the exported loop in another DAW (Magix 2013 for instance), the loop will import at a different tempo...in this case 108 bpm.  If I export the loop as a MIDI loop, the tempo is just fine and will import into another DAW as 90bpm.  So, it looks like the problem lies in the export of the file as a wav.  This creates huge problems, especially when I tell people a loop in 90bpm, sounds like it is 90bpm, but when put into a song with a bpm of 90, it drags and is useless.

So, what am I doing wrong?  It seems Magix programs do just fine, but Samplitude programs do not.  Any ideas of what I can do to change this?  I certainly don't want to do all of my loops in a tempo of 120bpm.  Thanks for any insight into this.

I am using a Toshiba laptop with Windows 7, 32 bit.

AJust an addendum to my previous post.  I also tried export recorded tracks (bass guitar) as wav files and the bpm info is wrong on them as well.  I imported a bass guitar wav file that I knew was at 80bpm.  I set the VIP tempo at 80bpm, and imported the wav file that was 80bpm.  Then I exported the wav file and imported it into another DAW.  It said the tempo was 120bpm.  I also imported a guitar wav file I knew was 90bpm.  Repeated the same process and set the VIP tempo at 90bpm.  I exported that wav file and the result was a wav file with a bpm of 180.  This means any wav files of live instruments will not have correct tempo data as well.  Meaning the Samplitude Music Maker 2014 is virtually useless if I want to export individual stems to tracks or loops.  Any help would be greatly appreciated.

Hi

This sounds like a classic case of incorrect bitrate for the WAV file.  

IIRC the standard settings are 44.1 kHz, 16-bit stereo.

Check the bitrate setting you are using I suspect you may be outputting 48kHz 16 bit stereo - which may be 'stretched' when imported into another program which cannot adapt the bitrate..

There is no such thing as BPM setting in the standard WAV file header for any program to pick up although this may be added in the INFO chunk of the file header - this is for information about the audio file only AFAIK.

HTH
