Ayrton Mistral S Fixture problem: 16 Bit PAN and TILT values not going lower than 32767

Hi,

I use: ONYX 4.10.1271.0 with Fixture Lib from 13.Aug.2024 (I cannot update becaue of M-Play USB Windows encryption problem).

I want to use the “Ayrton Mistral S” Fixture in Extended mode. And there a bug showed up:

The 16 Bit PAN and TILT values are not going lower than 32768. The coarse Byte stucks at value 128.

The Live-output of Onyx is showing that the complete range from 0 - to 65536 ist generated.

Also other fixtures like the “Robe Robin 600E” Fixture is functioning as expect over the complete range of the 16 bit values.

I can see the problem in an ArtNET debugger. If I control the Mistral by the Robin Fixture in ONYX, everything is OK. So:

There must be a misconfiguration in the Mistral fixture which I cannot find. I compared the settings of the Robe and Mistral and both seem to be identically in terms of the PAN and TILT settings.

Does anyboty have seen this problem before or is there any solution for solving this bug?

PS: Also with the most recent fixture library (3.Juny.2026) this problem is still reproducible

Eu também uso o ONYX versão 4.10.1271, pois tenho uma M-Touch. Minha biblioteca atual é de “22.Dec.2025”.
Criei um show novo aqui e adicionei o “Mistral S Extended” de 39 canais e monitorei a saída Art-Net do PAN e TILT em outro computador. E os valores de PAN e TILT estão normais aqui para mim.

Hi, if I want to use a newer fixture library, must i delete the fixture and add it again after loading the new fixture library? To see if the problem remains?

Hola, si quiero usar una biblioteca de fixtures más reciente, ¿debo eliminar el fixture y volver a agregarlo después de cargar la nueva biblioteca? ¿Para ver si el problema persiste?

Hi,

The fact you are using version 4.10.1071, does not mean you can’t update your library..

Make sure you are using the the Fixture Library 4.10 link (2nd library link)

The issue as described, does not seems to be library related, but rather an incoming Artnet loop, causing PT values not being abled to move under 50%…

Anyway, just tested the Mistral S profile, and had no issues…

Regards,
Ofer
