Thank you to all all of you for your constructive and instructive informations.
However, although I got something working, I am not satisfied with the result.
The drum section played by JS is not synch with the song that is played and overcrowed with a lot of erractic drum beats.

I have installed on REAPER track_1 a song (mp3) and on track_2 JS demo.
What I want to get is just (as a starter) a simple rhythm (just a minimalist beat) in synch with the song played on the other track.

That’s my goal. Can somebody help me ?
1000 thanks,

[Ralph [RZ]]

First off, Jamstix is always in synch with REAPER so it is important what tempo and time signature REAPER is set to. If you are using a pre-made audio track, you must set REAPER to match that tracks timing.

It sounds like you want to detect the drums in a MP3 file and have Jamstix play along with that; or extract/replace a drum track from an existing tune. Jamstix doesn't do that. Jamstix is more for composition.

If you want to fake it, try this:

First, figure out the tempo of the MP3 manually. I suggest you tap to the beat on the "BPM" label in the transport bar in Reaper as the tune is playing. This will get you close.

Then figure out the time signature of the song and change the Reaper project settings to this.

Next, set up the Jamstix drummer and style to approximate what you're hearing. This is a trial-and-error approach.

Finally, you will probably want to set up the "parts" of the song to match chorus/verse/intro/outro etc. This is probably the most complicated part.

Yes, this may be confusing, but it's basically using Jamstix to do something outside of its main purpose. It won't be perfect, and there are better tools to do this, but it might surprise you with something cool sounding that you didn't expect.

HI, thanks again for your replies ….

However, the more I go, the less I understand how it works.

I understood from Ralph “I am assuming your music file has no drums (otherwise you won't need JS as outlined above). You can now use the project from the steps above and add another track with your music file. After that, adjust the parts in JS to match the content and style of your music file by adjusting parts length/repetition and style/drummer selection”.

Now, BoxOfSnoo says « It sounds like you want to detect the drums in a MP3 file and have Jamstix play along with that; or extract/replace a drum track from an existing tune. Jamstix doesn't do that “.

Those 2 statements are contradictory !

So, once again, my initial request for a simple functional diagram with what can be done with JS.

I am convinced that JS is what I have been waiting for such a long time but I want to verify it on my own,

Thanks again !

I don't see how the statements are contradictory. I said I was 'assuming' your audio track didn't have drums since, as BoxOfSnoo pointed out, that's how most people use Jamstix.

This is how most people use Jamstix: they have a track without drums or are creating a song in their host using audio tracks and/or MIDI instruments and wish to add drums to it. They add Jamstix, select the desired style/drummer etc. and that's how they get the desired drum tracks.

A diagram of what Jamstix does would likely overwhelm you as the possibilities and workflows are many.

It may be best to get back to exactly what you want Jamstix to do. Based on your latest posts it appears to me that you have a single audio track with a complete song, including drums, and you wish to replace those drums with a Jamstix drum track. Is that correct?

Aha... the third possibility is this: you have a track WITHOUT drums, but WITH all other instruments, probably played to a metronome.

Is this true? I could explain how to do this, but I want to know if it will help, first.

To Ralph,

To the question raised by Ralph : “Based on your latest posts it appears to me that you have a single audio track with a complete song, including drums, and you wish to replace those drums with a Jamstix drum track. Is that correct?”

My answer : YES, it’s what I want to do. I want to evalue how JS can play its drum part while "hearing" an existing audio file (complete mp3 song in my case).

Merci

Ralph,

OK, but in my case there is no drum track into my audio file. There is just a couple of guitars.........

Anyway, what do I have to do to evaluate your product ? Is my request realistic (or not) ?

BTW, I do not see any difference between a sound coming from a file and a sound of a music instrument plugged into a PC.

Can you please, enlighten my understanding ?

Thanks

[Ralph [RZ]]

Your request is not realistic because you want Jamstix to magically 'understand' the guitars in your audio file and produce a fitting drum track. There is no product on the market today that can do that. We are working towards that but it is still not possible.

Here is what you can do wiyth Jamstix today:

- load your guitar audio track into your host
- set tempo and time signature of your host to match your audio track
- add Jamstix and select style/drummer that fit your audio track

It can take a little time to learn your way around Jamstix, but it's well worth the effort. Now I can usually get the results I need with a few mouse clicks, but at first I was constantly referring to the manual.

If your audio track doesn't have a constant tempo that you can set your host to, one trick I've found that works is to split the audio file up into 1 measure fragments, figure out the tempo of each clip (if your host can time/pitch stretch loops, it should be able to tell you the tempo of the clip), then manually put tempo changes into the project to match the tempi of the clips. It's a bit time-consuming, but I've had good results using it to create a tempo map for older stuff I did 25 years ago. That way, Jamstix will follow the tempo of your recording.
