*Feature Request* Extra tempo synced speeds for modulation

[ulrik]

@clumsybear @SteveRiggs
However maybe you need to get the hostBpm from the NoteOn CB or set a timerCallback, if you have tempo changes in the host

[SteveRiggs]

@ulrik Thanks, man. I thought there would be a way with arrays and halving the values.

It would be a lot less time consuming if they were already in options though to just select. I have 1 project that I'm toying with which has 12 different LFOs, so that would be a lot of unnecessary code to link all of those.

[Christoph Hart]

Yeah the problem is that it there is a index to tempo sync value and I can't add new ones without breaking old projects. But triplets and duets are already included.

The core.tempo_sync node in scriptnode has a multiplier value, which should get you to almost every imaginable sync value (eg. 3/8 can be done with selecting 1/8, then set the multiplier to 3).

[SteveRiggs]

@Christoph-Hart Ah no problem. That makes sense.

I'll have a look at the scriptnode way. What is the LFO node called? I haven't spotted one so far.

[ustk]

@SteveRiggs You have to use the oscillator followed by a sig2mod node

[SteveRiggs]

@ustk Thanks man. I'll give that a try :)

[ustk]

@SteveRiggs If you're using a scriptnode synthesiser, you can also use the core.hise_mod, which is connected to the Pitch, Extra1 and Extra2 modulation tabs of the synth module

Hey @ulrik,

Really nice snippet that you've put together here.

It might actually be a good work around for the temposync issues that I'm currently facing using scriptnode ( https://forum.hise.audio/topic/2120/flanger-in-scriptnode/17)

One quick question.
How did you go about getting the actual hostBPM from the host in your example, instead of simulating the Host using a slider?

Appreciate your insight

[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
