Metadata - multiply/divide metadata ( BPM ) by 2 ?

[alec.tron]

Heya,
what's the best/easiest/hotkey map-able way to:
- query a metadata field ( 'BPM' in my case )
- run an operation on the value
- re-inject the value into metadata
?

The only path I see for value manipulation could be regex... but not sure if arithmetic is something regex should/can be used for even, generally or in MB specifically...

Cheers.

its a very old request to add basic arithmetic operators to virtual tag functions. suspect that now it can be very easily done via simplified plugin format "mb_CustomFunc*.dll". Steven if its so please confirm and i will write simple plugin.

No worries boroda74! I just added this in foobar as a masstagger script & added /2 & *2 as a hotkey, and this will do for me. No need for me to solve this in MB.
Thanks for the offer though!
