Hi, Following my testing of the azimuth/elevation MIDI automations, I have a few questions about their range and how they are linked to the visual positions. These are not bugs, but perhaps some points that can be adjusted ? See this video : sonart.free.fr/temp/Zephir-auto.mp4 (I hope that my explainations will be understandable !). When I automate the azimuth position from minimum to maximum, the sound position does a 360° path from center, which is both logical and can make things not so intuitive when drawing or retouching automation curves. Perhaps it would be better to have 180°L > 180°R, with the Center at the middle value ? Anyway, when I control the same parameter with a MIDI CC, this time it is mapped from 180L to 180R. In fact, I needed to limit its range to 126 values because value 127 made it return visually to 180 L (not audible of course). For the elevation, it is different since, as you can see in the video, it starts at 90Down, goes up to 90Up and down to 0°. The values that logically must correspond to 0° to 90Down do nothing. Is this on purpose ? When controlling with MIDI, the full 360° are mapped from 0 to 127, but in the other direction : it begins at the middle, goes to 90Down, then to 90Up, then to 0°. All of this makes difficult to edit or to control : could you find a way to improve the correspondences ? Thanks !

All of this makes difficult to edit or to control : could you find a way to improve the correspondences ? Thanks ! The issue is indeed related to the correspondences between midi to angle values, (specifically elevation). I may need to add a table to manual to make this transparent. In short: Elevation-midi 0 => Elevation-physical -180 Elevation-midi MAX => Elevation-physical 180 Elevation-midi MAX/2 => Elevation-physical 0 Azimuth-midi 0 => Azimuth-physical -180 Azimuth-midi MAX => Azimuth-physical +180 Azimuth-midi MAX/2 => Azimuth-physical 0 What this means is that for the "nose-direction" or neutral position, you want midi-values for both elevation and azimuth to be both centered at MAX/2. Useful settings: [Canonical planes, Source azimuth MIDI, Source elevation MIDI] [Horizontal plane level to nose, Any, MAX/2] [Median plane intersecting nose, MAX/2, Any] As for the indicator flipping from min azimuth left max azimuth right, this is due to the overlap in values at -180 and 180 azimuth. Limiting the max azimuth value to 179.5 on my end will fix this.

Thanks for the limiting azimuth value ;-)
Controling the polar space with an XY joystick or pad is always a bit confusing. The 2D view can show the full 360° azimuth, but only 90° with warping for the elevation. One can prefer that the XY center corresponds to the top center (voice of God) at 90° elevation...
For the rest, you are right, my "problem" comes when combining MIDI control and automation (in Reaper) : the values are adding, making positions shifting. I will have to dig inside...
