Tempo sync

#1

Any insight into tempo tempo sync and how to implement tempo and tempo control with widgets in different modifiers"opcodes" and instruments would be really helpful :+1:

#2

Do you mean tempo sync from a host DAW?

Hi,
this question is pretty old but I was looking for the same, found the answer looking through the cabbage examples and then looking closer in the manual:

Manual page explaining how to get information from the host (like host tempo, BPM)
https://cabbageaudio.com/docs/host_info/

So getting the host tempo would be like:

kBPM chnget "HOST_BPM"

although I saw in the examples it was used like this:

 ktempo    chnget    "bpm"                ;tempo taken from host BPM
  • where “bpm” seems to be a short form of “HOST_BPM”

maybe this will help others in the future.

kind regards,
Stefan

It’s definitely HOST_BPM you need to query. I’m not sure what’s going on in those examples :thinking:

hi,
interesting! I’m really new to cabbage (two days basically).
I just searched the cabbage examples directory, only 2 of the examples call chnget “bpm” without defining that channel elsewhere.
Wouldn’t that suggest that it’s a reserved channel as is explained on the above linked manual page?
I must surely be missing something, both examples DO call chnget with “HOST_BPM” at another code-location.
Hopefully this is not too off-topic…

The two examples that use it are
[…]\Cabbage\Examples\Effects\Time\CrossedDelays.csd (line 127)
[…]\Cabbage\Examples\Effects\Time\TempoDelay.csd (line 61)

Kind regards

Ah great! Welcome to the forum and good luck with Cabbage!

I think we would need to ask @iainmccurdy. But I can tell you with absolute certainty that there is no channel called “bpm”. Perhaps there was way back when I was first writing Cabbage :thinking: That might explain it.

I think it’s actually an error on my part. I seem to have reused a block of code with the error in these two example.
Thanks for pointing this out!

thanks for the warm welcome @rorywalsh and clarification @iainmccurdy!
I will stick with HOST_BPM for sure then :slight_smile:
you will surely read another post of mine soon as I’m digging in deeper with cabbage!
I really love the spirit round here already! :space_invader:
