### Bug Description

I synchronized the two trackers via MIDI, but when I stop the master tracker and exit Perform mode with the other tracker, the slave tracker freezes

### Steps to Reproduce

1. The Main tracker’s MIDI out goes into the slave tracker’s MIDI in.

2. After exiting the slave tracker’s performance mode, the clock continues to run.

3. If I stop the Main tracker, the slave tracker freezes.

### Occurrence / Frequency

Always

### Found in Firmware

- **Version** : TrackerPlus\_1.2.0
- **Build** : TrackerPlus\_1.2.0

Hi @martinszijjarto Thanks for reaching out about this issue.

I just tried, and hooked up two Tracker+’s with 1.2.0 firmware.

I haven’t been able to freeze it so far.

Could you link your project? You can send me a DM if you don’t wish to share it with the public 🙂

Hi @borsuk

Unfortunately, I can’t share the project anymore because I only have one Tracker+ now, and I didn’t save the projects.  
Sorry for the late reply, and I’m glad you didn’t experience any issues on your side.
