Changing tempo of a midi recorded at the wrong tempo?

Hi everyone,
 
I feel embarrassed to even ask this question on here, but I've never been faced with this before and was hoping you might be able to help me out please?
 
I have a client that sent me a midi drum file of him playing on a Roland V Drums kit that he wants me to run through one of my modules to cop better sounds.
 
The file he sent was recorded in real time without adjusting his tempo to the correct time in the Sonar work file. He has it at 98.50, yet when I tap using the metronome, it comes out to about 116 bpm.
 
If I change it to 116, of course it really speeds up way too fast. I've tried importing just the midi aspect of the file with a starting point on my end of 116, but that still made it too fast. Do you have any ideas for me as to how I can get the right tempo so I can quantize this and fix it to time the right way?
 
I'm stumped on how to fix this because I've never been faced with this before. Any help would be really appreciated. Thanks in advance. :)

brundle, sorry to ask, but can you be a little more specific? If it's too in depth for you to post, that's understandable and I'll try to search for the answers. I was just hoping there might be a quick fix. When I do what you said using Sonar 7, the window (ctrl m) pops up with options of 1, and 1.000.

Another option is below it that says meter and has beats=4 and beat value=4. I tried messing with them and it keeps on reporting back "unable to define values". So if it's not too much trouble to explain, I'm all ears. If it is, that's fine...I'll try to see what else I can dig up. Thanks for the reply. :)

Danny,

Just for grins, go to the start of the project, click on "Insert"-->"Tempo Change"-->"Change the most Recent tempo"...set it to 98.50 and see how the track playback sounds...

Sorry. Just trying to leverage stuff I've posted previously. Here's a good one:

I did this to myself last night, but sort of deliberately.  The piece was locked at 80bpm and I recorded a 'freestyle' Rhodes lead, paying little attention to the click track.  The impact of which is that it plays in 'time' but is no longer quantizable, other than doing it manually.  In my case it's not an issue because the data is not time critical, unlike the drum track.  What you really need is to be able to copy the note and timing information in absolute terms into a track with a different tempo.

Danny,
I've done this many times to piano and drums.  My suggestion may not be the best but it works.
 
Go to the note that is the downbeat (Count one) of each individual measure starting at the beginning of the song.  Press Cntrl-m and set that note to beat one of that measure, for this discussion say it's measure one beat one.  Then go to the note that is the downbeat of the second measure and repeat (cntrl-m beat one measure 2) to the end of the song.  If there is no note for count one you can either set Now Time where count one occurs or use the next available down beat.
 
HTH,
Rich
 
Edit to add:  Once you do this you will be able to quantize and/or change the tempo as you see fit.

Audio snap is very good for this. The latest version works really well and I see a very good step by step on here a few days ago.
Go to the techniques forum and you will see the problems I had with this. The jargon got me. But it works but its not that easy. The guys were light years ahead of me.

LOL you guys rule. Thank you all so much for taking the time to give me some things to try.
 
brundle: no worries, I know how much of a pain it can be to post stuff you've already posted. Thanks for the links and the explantions. I was hoping this would be a little easier to be honest, but it appears there is no easy way to do it.
 
papa: thanks for the offer there. I nearly took you up on that thinking maybe between the 2 of us, we might have been able to figure something out...maybe discover something new. Then it hit me...which is pretty much what dmbaer mentioned.."why do I even care"? LOL!! Which is kinda true...I'm just a perfectionist and felt, since the guy will be totally retracking all his instrumentation, I could fix a few of the snerts inside the drum part and it sure would be helpful if it was at the right time and could be quantized a bit. But he's not paying me for that, so I shouldn't really worry about it. I just don't like to let things go when they are a bit loose and I can help fix them a bit. Thanks again.
 
Psalm: I'll definitely log that info as well as what the others mentioned, thanks for that!
 
fitzj: my first idea was to use AS for this in hopes it might be a quick fix. My dealings with it have only been for audio though, and when I right clicked on the midi expecting to see AS show up in the menu like it does when you do it for audio, I had assumed that it wouldn't work on a midi file due to my lack of knowledge on how to use it. Thanks!
 
dmbaer: you're right in what you said. As I said above, I just try to deliver the best work I can and really wanted to tighten this thing up for the guy. I was thinking the whole time "if this is just something easy that won't take much time, I'd rather attempt to deliver the goods over just routing the midi to my sound modules and shipping it". But it appears that no matter what road I take here, it's going to be a bit time consuming and it's really not part of the deal that I have with this guy. Thanks for your help...and to everyone else, it's much appreciated everyone!
 
I decided it would be best if the guy re-plays the part because there were a few things in the drum track that definitely need to be fixed. When I pointed them out to him, he agreed with me and was thankful that I brought the mistakes to his attention. So we should be good to go with a new file in the right bpm by tomorrow. :)

Coming late to the party - I have a very similar problem - my friend recorded a live band. The drummer was playing an electric kit, which sounded poor in the recording, but, problem solved - he had also captured the midi in Protools. Only problem was that he had the BPM at an arbitrary 120, whereas in fact it is between 155 and 156 (slightly variable) .
 
Now I've imported it into Sonar X1 to sequence some keyboards on top. Using the audio track from the drums, I created a tempo map and lined up the keyboards pretty nicely. But now, if I bring the midi drum file in (because I don't like what my friend did with the drum sounds and want to re-do it), it's all over the place.
 
Could I tell sonar that one track is at 120 and the rest follow the 155-156 tempo map?
 
Even if we do this again, we are never going to persuade the drummer to play to a click at a live show, so we are going to get the same problem.
