Making a Meta Device

Renoise Tool Development Beginners Lua API Sandbox
1

Hi,

I’ve got an idea in my head for which I would have to create a Meta Device… essentially I’d like to make a device that takes several inputs, similar to the Meta Mixer, but always returns the highest or lowest of the values (max/min). As far as I can see no Meta Device available so far can do this, correct?

Now I don’t know the limits of the scripting API yet. Is it even possible to script a new device that can go in a device chain?

Copy and paste this to your Renoise’s DSP chain.

Amazing. Why did I not know about this device and is there any way to get it into my DSP list?
Are there more hidden devices I should know about?

It’s not hidden, he just wrote it for you. ;)

Sure ;)

I’ve just talked to mxb and he says it’s highly unstable and might crash Renoise or prevent a song saved with it from loading. I’m going to use it anyway for my simple max(A,B,C) … but should anyone else just have found out about the device through this thread, be aware.

The overall Formula Device is hidden though!

I’ve only had it crash in 2.7, but I haven’t used it that much since.
