*Feature Request* Extra tempo synced speeds for modulation

[d.healey]

@LeeC I haven't looked at the code, but I would guess Engine.getHostBmp();

[ulrik]

@LeeC as David said "Engine.getHostBmp();"

[LeeC]

Thanks @ulrik and @d-healey

More specifically, the question was how do we get a change in BPM within a DAW to trigger an action in HISE using code?

I guess, I was expecting there to be some kind of call back function.

Thanks again

[ulrik]

@LeeC I guess you have to use a timer that continuous checks the host tempo

[LeeC]

@ulrik ok thanks.

Any thoughts on how frequently to call Engine.getHostBmp(); using a timer?

Also, will this method eat up unnecessary CPU?

Thanks again

[ulrik]

@LeeC I don't think the timer will eat up much cpu, but maybe some more qualified can answer that.
I think you should try to set up a test plugin and run it in your host, you could even make button and a slider in your plugin, slider to change the timer freq and a button to restart it.

I'm just speculating now but maybe the code
"Engine.getHostBmp();"
will check the host continuous already? or maybe when the host change tempo it spits out the information the plugin will respond immediately, I don't know?
Maybe some with more knowledge can chime in?

[d.healey]

I think the timer is the only option at the moment. If would be nice to see some host callbacks for bpm and transport states @Christoph-Hart ;)

[ulrik]

@d-healey but what about all modulators "Tempo Sync", they follow if the host change tempo, so there must be some inbuilt function there?

[d.healey]

@ulrik I don't think we can access it through scripting though. Might be able to with scriptnode...

[ulrik]

@d-healey Ok.

[LeeC]

@ulrik @d-healey

Yes I was excited to see @Christoph-Hart push some new features to the tempo.sync node in scriptnode a few days ago.
However, exported fx using this node sound very strange when using them in a DAW as mentioned in this thread https://forum.hise.audio/topic/2120/flanger-in-scriptnode/17).

I’m gonna keep exploring the timer solution for now
