MMetronome does not work in Tonelib Jam Host (but shows dynamic BPM)

[xo-vision]

Good morning,

I use Tonelib Jam to learn & practice new songs on bass guitar. I can use any VST plugin I like and everything works perfectly, except MMetronome. I have purchased the bundle.
MMetronome does work in Studio One 6, so installation is ok.

The funny thing is that the BPM changes in the MMetronome UI, in sync with the song - so it is working in principal. But I neither hear the metronome nor see the metronome moving.

My guess is that it needs some kind of start signal. How can I do that?
Even better: is it possible to add a start/stop button in the UI?

I don't know this tonelib, but MMetronome simply requires the DAW to implement the interface properly - let it know the position, tempo, signature and whether it is playing. I assume you'd be better of with a different daw.
