Hi-
I have an analog synth I built from MFOS modules. I would like to record the sequencer on a computer and then use some program to identify the BPM so I can sync the sequence with a drum track.
I have used Sony Acid's beatmapper, but it doesn't do a very good job. Is there something out there that can do this well?

I saw a tutorial for SONAR that had a method of detecting beats and allowing a user to line them up. I have never used this feature so I can't tell you much more. Perhaps there are other SONAR users around who have used this. I am not sure if the tutorial is available on line for free or is a chapter in a larger, for pay video. I will look for the name of the feature and see if there is a free tutorial.

Does the track have a constant beat?

Steve

Addenda:

This is not the video I recall seeing, but perhaps it might be relevant. Its about the AudioSnap features: http://www.cakewalk.com/Products/SONAR/X1-Producer/feature.aspx/AudioSnap-2.0 .

There is also something dealing with beat detection and manipulation working with clips in an Advanced Workshop video (paid video), but I am not sure it would meet your needs since you want to add a drum track.

Go to this website for an aproximate bpm reading:

Actually, once the sequence is in the computer (which program?) look at the waveform view and measure the time between notes. Then use the time to calculate beats per minute. Don't forget to take into account what your sequence note values are supposed to be. i.e. 1/4, 1/8 note etc. It might be easier to also record the clock driving the sequence into another channel and trying beat detective or whatever other aps you might have. The clock should give a pretty good spike that will make it easier for the apps to determine the beat.

Check you software too and see if it has a tempo track or mapping.

Quantizing is dead simple in Logic. Put the track in flex mode and choose the smallest note value.
Usually you have to manually adjust a few spots but it works pretty well.

Once it's quantized you can set it to any bpm you like.
