Hey this may be a stupid question but how do you control a number in a message box? It only has 1 inlet

I'm using message 'set 1' to control object 'block~'. (Controlling the blocksize for a delay)

I want to use a controllable knob to change the numerical value. I thought 'set $f1" would take the float that would come in from the knob.

Appreciate any help

Cheers

$1, $2, $3 etc. instead of $f1, $f2...

If you're using more than one variable, use [pack] before the message

cheers
