Maths Builder Module

I'd like a module where I could chose the math function from a combo box to apply to 2 inputs.
A wide range of math functions would be superb and a great addition to the output would be the chance to apply an offset.

order of operation could then be defined by the structure of the modules

Ideally I'd wish for a text box to enable the input of the math function to be applied.

Cheers
David

Have you checked: http://cwmodular.org/ and http://www.modularsynth.co.uk/ ?

I remember seeing a bunch of free maths modules knocking around there...

Wow Will, how these modules ever escaped me I'll never know!
Thanks for the links.
I'd been looking for an all-in-module but for why I don't know.
These are just the ticket.
More ammo for the armory!

There's a variety of math modules in Scope, too, some named more transparent than others:
* ringmodulator, a classic multiplier, but it actually divides, so that
a ringmod b = a/b
so a/b is part of [-1,+1], and ringmod never clips.
If you do not have m3, and the invertor, you can ringmodulate with -1 from ValMonitor or ConstVal Bipolar.

* "Division x/y" actually multiplies - it's the opposite of ringmod!

* "adder" adds or sums, but mind you: add2 actually does
a/2+b/2=c
so c is part of [-1,+1] and adding never clips. In the SDK there's 2 versions of this: a normalized and a non-normalized version. For the Scope Modular version, you can add 6dB Gain or ringmod with .5 For subtractions, you guessed it, add one inverted.

If you have FleXoR, much more maths can be achieved with the Osc Shapers, and ValMonitor or Absolute Val are great 'number setting' and monitoring tools - or get some free ones @ http://cwmodular.org/html/math.html like w_ellis suggests. Also j9k has some maths and logic modules...

Scope is alive with the sound of math

Thanks guys these are great
