Hey all,

Boele Gerkes' A6 editor for iOS is great, but I would really want one that runs on both OSX and Windows (possibly Linux).

I believe the right platform for implementation is the Chrome Browser, since it provides MIDI access to hardware devices in JavaScript. This would benefit everyone, because Chrome runs on all platforms.

I used to be a web developer years ago (PHP/JavaScript) so I do have some programming skills. I need to re-learn a couple of things though, because I've been out of the loop since around 2010.

I would like this thing to be an Editor AND a Librarian, possibly with a Cloud-Based patch exchange platform. This will propel the A6 into the future!

Since I'm also playing in a band and producing an album, my time is limited. I will very likely need help:

- Full MIDI, Sysex, CC and NRPN implementation of the Instrument
- Graphics, since I'm lacking visual design skills
- Maybe GUI programming -- I can do that myself, but it would likely speed up the project if someone could help with this.

I'm willing -- even itching -- to start developing this over the coming winter. But please be aware that this project may die as most others -- I can't make promises. I can only say that I really really WANT this Editor/Librarian to happen.

What do you say?

Cheers,
Helge

I started exploring WebMIDI & JQuery recently. Seems promising, Chrome can talk to my Andromeda with no problem!

My plan is to first create a Parameter-Only Editor (no GUI, just the names of the parameters in a very long list with input fields (dropdown, text, radio button, etc). It will look very similar to the parameter-only view of plugins in Logic Audio Pro.

Once this is working properly, one can start thinking about a proper GUI.

Cheers,
Helge



EDIT: I am also thinking about putting this future Editor into a Raspberry Pi (with 32GB Flash, Wifi, USB-MIDI, Ethernet & HDMI) and install the Pi inside the Andromeda.

Hi, I just accidentally an andromeda, and I'm looking forward digging into the patch format.

I'd like to parse the modulation routes of a patch, as it is quite tedious to define them on the synth, or just to get an overview of all of those (say what are all the destinations of LFO1, that kind of questions)

In the documentation there are 36 sections of modulation, and there is a source and destination byte for each, but I don't understand what they correspond to.

Anyone dug into the binary format yet?

Are you guys on any slack or irc channel to hangout and discuss between software guys?

Hey all, Gauthier msg'd me recently, and we're now both looking into the details of an editor/librarian.

I've recently converted the actual sysex implementation PDF from Alesis into XML and JSON (with only minimal manual interaction). In theory, this data scheme contains everything needed to control the instrument via NRPN and/or Sysex. I'm reasonably confident that I can come up with a proof-of-concept editor soon. It will be based upon Chrome, WebMIDI and possibly the Webaudio-Controls framework for GUI interaction. It'll be cross-platform (Win, OSX, Linux, maybe even mobile). It'll also be ugly, since I'm not a graphical artist...

But the devil is in the details, so don't hold your breath just yet Smile

Mainly with E-Mu sysex, I have dabbled with Ctrlr and the Jazz-Soft plug-in (though with browser-based buttons, not a sophisticated GUI). I have thought of converting my web pages to use WebMIDI and would be very interested in any insights you might have (now or in the future) on using WebMIDI with sysex. If there isn't a WebMIDI topic in the forum, perhaps you would start one (or contribute to it, if there already is one).

I am aware of a GUI editor for the Casio VZ line using the Jazz-Soft plug-in and I think it's handy to have browser-based tools like this. If it would be helpful to your design of the GUI, I can grab some screen shots--thought it is really basic, not fancy at all.

I'm not a graphical designer at all, so I am planning on creating only a very crude version, comparable to the Sliders-only view of AudioUnits in Logic Pro.

Actually, the data structure that I have derived should lend itself well to auto-organizing everything into around 40 tabs (think: OSC1, OSC2, LFO, ENV1, ...) without much human interaction. This will not look too great, of course.

But if this proof-of-concept does work, I'll get back to the community to ask for help in making it look nice.

As for WebMIDI, what I can say is that it does work and I can talk to the A6 fine, but that's about all that I've done so far. This will change soon, maybe already tonight Smile
