Hi Brendon,

I’m quite new to IanniX myself but I’ve started looking into the source code to make some modifications and may be able to help you with at least some things.

>>> Regarding Font display:

I’ve run IanniX on two different Windows 7 systems and two different Macs and have not had this problem except maybe in the message editor, and maybe the text is somewhat small, although I’m running at 1920×1200 resolution. I see you are running on Windows XP so that may be the problem. I do have an XP system so I’ll download IanniX to it and see if the same thing happens. Also, IanniX is written with the cross platform frameworks QT so I’ll have a look in the QT support forums for reports of problems with XP. What screen resolution are you using?

>>> ‘?’ does not point to documentation

There should be a « documentation » folder in the folder where IanniX.exe is located. In that should be the file « index.html » which is the documentation. Did you install IanniX version 0.8.21 for Windows from here: https://www.iannix.org/en/download.php ? If you downloaded this and just unzipped the contents into a folder and run the exe the directory structure should be set up correctly with respect to the exe.

However regarding documentation, recently much better documentation has been posted online here: https://www.iannix.org/documentation/EN/

>>> ‘Open Patches folder’ does not do so

Again it sounds like problem with the directory structure from where the exe is located. It should contain a patches folder.

>>> Inspector logic: On the very first running of Iannix, the inspector Score centre lists the example scripts. On subsequent runs, the scripts do not display requiring me to open the example folder as the project folder (File – open project folder)

This may be a problem with the directory structure too. Double check that the folder where the exe is contains all the folders as they are laid out in the unzipped application download. If the exe file’s folder contains an examples folder the examples should be seen in the « Styles and Scripts » list in the « Score Center ».

>>> Examples do not always open/run.

May again be a problem with folder structure.

>>> Midi example sometimes opens with triggers and but most of the time has no triggers.

I’ve never seen this problem. There is something strange about your installation. Try downloading Windows version 0.8.21 again, keeping the directory structure intact. If the problem still occurs it will take some detective work to figure out what’s different about your system/setup that is causing this. It may be relate to the text display problem.

>>> After closing the script editor, I can’t work out how to open it again.

This confused me at first too. The script editor should reopen when you double click on a script to run it, which also opens the editor. I understand script editing is only newly added and not complete yet. I would like to see the behavior changed so you can see a script BEFORE running it so you can verify it does what you want or to change it as required.

>>> Regarding Project management (project folders & saving etc):

I also find this confusing and I think some improvements could me made. I’ve unofficially started to think about improvements (although I’m not part of the IanniX team). What problems are you having?

Hi Guillaume, that’s great about the new version.

I’ve made a number of enhancements to my private version of IanniX which I synced to the svn version and am tracking with GIT on my system.

The enhancements include:

– support for pitch bend as a « /bend » MIDI message type
– the addition of some additional parameter types that can be used in messages including
* trigger_distance: distance from the center of cursor to the center of the trigger
* collision_distance: distance from the center of cursor to the intersection of the cursor with the collision curve
* trigger_angle: angle of line between center of cursor to the center of the trigger
* collision_angle: angle of line between center of cursor and intersection of the cursor with the collision curve
(implementation of the angle parameters is underway now)
– support for embedded Javascript expressions in messages. For example the message midi://IanniX_Out/note 0 {127*(trigger_distance/10)} trigger_value
would return MIDI note numbers scaled based on the trigger_distance, assuming the maximum possible trigger distance was 10.
Anywhere a single parameter can be used, an expression enclosed in { } can be substituted and the expression can used any of the parameters that could have been used directly in the expression. Whatever number the Javascript returns is entered into the message in place of the expression.
– I also made a few enhancements to the parameters, notably to the « collision » ones, as currently if these are used in a message and a collision is not occurring, that field is blank in the message and this can displace any parameters following that parameter so they may be mis-identified. I added return value of -999999 as a place filler in these cases. I also added a « colliding » parameter that is 1 if a collision is occurring and 0 if not.
– In working with the cursor-angle parameter I noticed that it always returns a negative angle, if I’m not mistaken. The correct positive angle I believe would be given as 360+cursor_angle.
– I’d also like to add a trigger_angle parameter that would be the angle of the line from the cursor centre to the trigger at the time of a collision. This combined with the cursor-angle could be used to compute (with the embedded Javascript) the angle to the trigger relative to the direction of the cursor. i.e. The angle as it would be seen from the frame of reference of the cursor. Geomaestro support this and it allowed things like panning the sound as it would be heard by an observer riding on the cursor.
– Similarly I’d like to add a collision_angle parameter for cursors colliding with curves.
– I have some other ideas but I think that’s a summary of what I’ve done do far.

I have the source code for these things, which is quite localized in the code, tracked as changes in a GIT repository so if you are interested I could send you the code.

– Chris

There are a few other things I’m planning to add in the next few days:

– Some helper functions available in the embedded Javascript. The most important would be scale(in_min,in_max,out_min,out_max) that would be like the scale object in MaxMsp, and would rescale a parameter ranging from in_min to in_max into the range out_min to out_max. There might also be a version that scales logarithmically. These things could be implemented with the embedded Javascript but would be so commonly needed that it makes sense to provide them.
– The ability to have the MIDI /note message control the note duration. I suggest doing this by allowing an additional parameter at the end of the message that, if present, would set the duration for that note. If the parameter is omitted the note would be the length set in the inspector. (I haven’t looked into the difficulty of implementing this yet. The extent of the changes necessary depends on how the note-off timing is implemented.)
– I have a bunch of other ideas but you may have already done some of these things in the new version so I won’t discuss any other ideas right now.

– « /bend »
Ok, MIDI is not our favorite protocol, but good idea! Can you send me the piece of code todo that? (guillaume@iannix.org)

>> I also use OSC into Supercollider but I like MIDI for direct access to acoustic instrument sounds.

* trigger_distance & trigger_angle
Ok, I’ll add this.

>> I have trigger distance implemented so it will be in the code I send you.

* collision_distance & collision_angle
Ok, I’ll add this.

>> I also have collision distance implemented

– support for embedded Javascript expressions in messages
Oh yeaaah. I want you piece of code to do that (this is a feature I wanted to develop, but not enough time!)

>> I have it working and I’ve tested it fairly extensively. The one thing my code doesn’t do at this time is support spaces embedded in the Javascript. The splitting of the messages using space delimiters is in a different place from the rest of the parsing so I was leaving this for later. It would be nice to be able to have spaces in the Javascript, and it would not be too hard to add, hopefully with no bad side effects. You would know of possible side effects better than I do. I also don’t support Javascript in messages EXECUTED from scripts, only from objects. The parsing of script-executed messages was different and would have taken extra work, and I didn’t think it was very useful anyway. However scripts can of course attach messages containing Javascript to objects.

– The ability to have the MIDI /note message control the note duration.
But you have triggerOff parameter in the inspector, maybe it can help isn’t it ?

>> Trigger off does not do all you need. Presumably you set a timer to cause MIDI offs so the message isn’t around any more when the note needs to be turned off. trigger_off certainly will be useful in some cases such as where you want one trigger to turn a note on and another to turn it off, but not for the timed-off case.

Waiting now for some piece of code, then I can package that.
Btw, are you on Mac OS X or Windows?

I’m developing on Windows 7. I also use Macs but I prefer Windows for development. Haven’t installed qt on the Macs. I might at some point.

P.S. If you want someone to help with testing the upcoming release I’d be pleased to do that. These days I have time available to work on IanniX.

I propose to extract all the changed files from my repository, zip them and email them to you. Would that be the best way to send the code?

– Chris

I now added the ability for my Javascript expressions in messages to have embedded spaces which will be good for readability. Now expressions like this are possible:

midi://VMidi2/note 1 { 100*Math.sin(cursor_angle + 360) } { (cursor_yPos>0)?127:0 }

To do this I modified the message entry parser in extoscpatternask.cpp.

I’ve tested all the boundary conditions and it seems to be working fine. Let me know if you want to me send you this file also.
