Hi, I have a problem with Scaler 2.4.1 and Logic 10.7 on iMac M1 (Monterey) After creating a track and adding Scaler as a Midi Plugin, if it is duplicated it stops playing and the midi information is received only from the duplicated track. 🤔 Maybe it depends on Logic’s new midi routing system, but I haven’t found any documentation about it… For clarity, I have posted a video [https://youtu.be/w62QDYKUf6c](https://youtu.be/w62QDYKUf6c) Does anyone have the same problem? Is there a way to fix it? Thanks ---

Hi @Pinzer thanks for reporting. Logic 10.7 seems to have fixed some issues on M1 but not everything. Have you tried running Logic with Rosetta? ---

Thanks! Yes, it happens with Rosetta too … but I did some tests and it happens with other third-party “Midi FX” plugins too. 😥 With native “Midi FX” everything works fine. I tried to report it to Apple … let’s hope so! ---

I’ve seen the same, any 3rd party midi FX seems to stop the midi getting through to the instrument. I’ll bother Apple about it too! ---

> [@Blorp](#): > > I’ll bother Apple about it too! Thanks, Blorp! We hope others do and Apple fixes up quickly. I use Scaler very often and right now the workflow becomes complicated … But you know, every update solves some problems and creates others !! 😒 ---

Very frustrating and the reason I can’t progress all of our studios to M1’s. Also a reason I think the next MacPro will be Intel based. Reporting to Apple is a good idea. ---

I agree, I am a hobbyist so I just have to “curse” a little and get around the obstacle, but for those who work as a pro, updating too early is never good! We hope Apple will solve it soon! **fingers crossed**
