Subject description: First output of new G2ool
Reply with quote  Mark this post and the followings unread

Hi everyone, here is a prf featuring the first output of a new web based tool I'm working on.

It basically takes a standard midi file, displays track info and notes on a grid, then re-factors the notes to fit into a g2 patch that you can download.

I'm not completely happy with the inter variation switching, but I think it stands as a good proof of concept.

Will post later with more info about the tool itself.

Don't forget to press play.

Here is a screen shot of the app. Still need to tidy up the code and add some features.

I like it! How many bars max, 32 ?

The template chains four seqlev modules for each row, I'm sure we could do eight for 8 bars per variation but we might have to spill into the fx area.

The first template works ok for 4:4 that is quantised to 16th notes. I have another that uses the x6 clock to give fewer bars at a higher timing resolution.

The bottleneck is the number of unique notes per variation. The allocation algorithm resets each note send to the note values used in the current variation while preserving any row that had the gate on in the last step of the previous variation. There is also only one velocity per step so it represents an average of all notes starting in that step.

The app is just standard HTML/css/javascript which will run on chrome/Firefox/safari. It almost runs on IE10 but the download link doesn't seem to work.

I'm not sure at the moment if I'll put it on line or make it available as a zip that you can run locally. I have a homepage account with my ISP but I think I have used all my space.

If you wish so Ian, I could put it up here on the electro-music server.

Thanks Jan

This site would be the most logical place to put it. I have found a 15Mb video on my homepage that was no longer required so looks like I have plenty of space for the Alpha version for the moment.

The app and resources are only about 70Kb so far.

So here is the link for the alpha.

This is purely alpha software at the moment so don't expect too much.
A lot of work to do yet.

You will need to download some midi files to your local computer and the template attached here. I used muss_7.mid which you should be able to find with google.

Known issues.

The code is currently dependent on the structure of the template patch, you can customize it but deleting any of the notesend or seqlev modules may cause problems.

I haven't coded for sysex in the midi file so it may fall over if present.

Before I used an external sequencer to fit a MIDI file into a g2 patch. It's very fast with your tool. It works well! Thanks!

Glad it is helpful.


New link has better version. The patch has been de-glitched properly with s&h modules. The page also lets you alter the time ref so if you have a file where the min note value is 1/4, you can scale it to get twice the length (halving tempo). Other factors allow for increase time resolution, the 1:6 might require switching to the 1/96 clock output.

Edit:
The last fix I did this morning corrected an issue with gates not extending to the last step in a variation seems to have caused some notes to be dropped. Will look at it again this evening.

When working, the code will go into a general purpose app that will accept midi, bin, wav, scala etc. I'm thinking of allowing js in the text pad of a pch2 file so you can write code to set sequence levels etc.

Another example prf2

Turns out some of the compressed notes were simply running into each other. Added some code to make sure the last 16th step before a gate start is zero.

I think the code is good to translate over to the main app now but I'll take a little break.

(updated the last prf to a version with the forced re-trigger)

Really nice! I wonder if any guy of Clavia has found your latest experiments here.

I'm not sure about the Swedes, but I have. You guys are like some insane closet wizards to concoct this amazing stuff. AMAZING STUFF!

Probably a safe bet that Clavia has seen it...

Bless,
