Hello Izzy community,

I am wishing to explore incorporating ambisonic technology with Isadora. Now that Isadora supports VST plugins I'm hoping this can be achieved.

My current experience using ambisonic mics is very limited. However, I now have access to a Sennheiser AMBEO VR mic and I'd like to explore what's possible.

I'm looking for some advice regarding which VST plugin's are recommended for the A - B format transcoding process. 

I'd also appreciate any general advice or links to reading material that focuses on using ambisonics within a live performance environment (ideally using Isadora if possible!)

I'm currently using a Focusrite Scarlett 18i8 as my audio interface which is providing a suitable means of capturing the microphone signals and sending on to Isadora.

Within Isadora's Scene editor I am using 2 x dearVR Ambi Micro VST plugins. From my limited knowledge of ambisonics the first of these plugins is the decoder and the second is the encoder. In the image below you can see each of the plugins with their associated DAW interface open and the parameters that I've selected.

From what I understand, 

• The first plugin (the decoder) has it's ambisonics format input set to "A-Format (AMBEO)" and it's output format set to "B-Format (AmbiX)".
• The second plugin (the encoder) has it's ambisonics format input set to "B-Format (AmbiX)" and it's output format set to "Binaural (dearVR)" this has been chosen from the drop down menu labeled "Headphones".

When using stereo headphones does this signal flow look correct?

I've also incorporated the dearVR PRO 2 to provide positional information for the audio source - I've attached an image of this too. I am hoping for some feedback as to whether this signal chain looks correct.

Thanks for any help or feedback, it's much appreciated!

Best Simon

I know @Michel did something very similar, but he's travelling right now and probably not checking the forum.

Hi all,

I would like to use TouchOSC (new version) to run a show from a couple of iPads. 
In my ideal world the interface that I'm building would show the Q number, the name of the current scene, and the Q number and name of the next scene.

Just wondering if anyone has already built something like this, to save me reinventing the wheel :-)

Thanks

Mark (no...)

 Unfortunately not. I believe Isadora binds to the first available device, which on PCs can change depending on config/build.

Do you want to start a support ticket, and I can dig into see if I can workout a workaround?

@DusX @Woland 

I've been looking back at feature requests to do with Isadora and its IP address setup and they go back decades, and nothing's been updated or changed.

I'm getting very frustrated when working on a machine with several network adaptors, to make sure that Isadora joins the right network with the right IP address.

Is there no way to bind Isadora to one adapter? Even better, isn't there a way to give Isadora its own static IP address? Everything else on my Isadora network that has a MAC address has a static IP:  cameras, switchers, projectors, etc. None of which connect if, on startup, Isadora decides to bind itself to the WiFi adaptor not one of the ethernet adapters. So I have to make sure to disable, eg, Wifi when I start up Isadora else it gets the wrong IP address.

Can I achieve this by hacking the preferences somehow? 

So just bumping up this recent thread and adding it to the many past requests to do with ip addresses :-)

I think this add-on might be what you need: TROIKATRONIX : ISADORA - DX – Rotate Canvas

It uses Matte to create a new canvas at the required 'rotated' dimensions, and then drops the image into this new canvas. 

@bonemap

Could you DM me the User Actor and/or patch so I can take a look?

Hi,

I have built, using Isadora, a touch screen interface for a Samsung touch screen overlay that has a USB connection. The overlay is in front of a 75” Samsung display. I have the display set in a vertical orientation. The final resolution is 1080 x 1920. Isadora runs on a Mac mini that sits behind the wall mounted display.

Everything is working well with a user actor module that can be duplicated to reposition active ‘hot-spots’ anywhere in the interface.

There is a single issue that would be great to find a solution. The touch screen is basically a mouse input connected to the computer via USB. It works accurately except for a users first touch of the overlay. This send the mouse sprite to the screen coordinate 0,0. The position of the sprite recovers but it causes some confusion for first time users.

Isadora is a great tool for this interactive touchscreen display and I have some approaches from other museums for touch screen development services that will include on-selling software licenses. But I will have to find a correction for this one issue.

Best wishes

I have made some test and a patch to test it. The best solution, with the least loss of definition, is:

Video input > FFGLPanSpinZoom  >  projector

scaling-test.izz

So it means, the best way ist to change the zoom factor in the FFGLPanSpinZoom actor.

Best regards
