Adding Frequencies

February 7, 2013 | 2:34 pm

So I’m creating a basic (but interesting) drone machine that uses 6 oscillators (separated into 2 banks of three). Each one can be tuned separately, but I want to be able to make a master transpose dial and also a transpose dial for each bank.
I’m using live.sliders for the frequency of each oscillator, and so I used a + with the transpose dial in the right inlet to be able to add the frequencies together. But nothing happens. Am I missing something totally obvious?

Could you please post your patch?
btw, reading to your description, I guess the problem is in the [+] connection, who will output values only when it receives messages in the left inlet.
Having a look at your patch would be mor helpful, though.

I will upload my patch when I have the chance later.
There IS a message going into the left inlet as well–sorry I didn’t mention that. The Left inlet is the adjustable frequency for the oscillator while the right inlet would be the added (or subtracted) transposition.

Thanks for the reply!

The right inlet of [+] is not a trigger, you need to bang the left inlet to do the calculation

Thanks Ploki. So I need to send a bang, maybe with a button, to the left trigger when I want the addition to take place?

Yes.

Trigger might be in place, because you can sort the message order. The rightmost outlet outputs first, so if you put a [t b f] or [t b i] (trigger bang float/integer) object before the addition, and connect the 1st (bang) outlet to the left inlet of [+] and 2nd (integer/float) outlet to the right inlet of [+] it should set the addition and bang immediately after.

like so:

Sounds good. Thanks a lot amigo. This should help.

Yep! It worked. Thank you.
