To anyone using Scaler 2.x in CbB; please confirm issue

[OutrageProductions]

I just noticed an issue (but just confirmed that it existed in 2022.11 as well on a different machine) and would like anyone here to confirm if you would in 2023.09.

1. Insert Scaler 2.x as an instrument track (track 1). It doesn't seem to matter if you use VST2 or VST3.

2. Insert a new MIDI track (track 2) and create a series of chord triads (altho the actual MIDI data seems irrelevant)

3. Drag-n-Drop the MIDI clip into the Detect section of the Scaler PI window.

Does your Audio Engine automatically disable?

This does NOT occur if playing the MIDI clip into the Scaler Detect section and recording the MIDI data from the MIDI track output to Scaler Track input.

Can anyone explain if there is a good reason for this anomaly? 

I wonder if this would be possible to fix in the expected SONAR?

This confused me several times (OK... actually phreaked me out!), until I just committed to memory to LMB on the Audio Engine button before playing.

@Noel Borthwick; not asking for a fix at the moment, just an explanation as to why.

Would have to check what scalar is doing. It's very unlikely that the problem is in cbb. The plugin may be blocking audio processing when you drag in midi.

Obviously it is not mission critical, but the first few times it happened, I scrambled to figure out what caused absolutely no sound after the operation. Chased my tail around all of the inputs, outputs, etc. for a while. 
I have a work-around, but just thought that it probably shouldn't be causing this behavior.
