The Neuronium page references touch sensitivity too in the page i linked : "The rotary knobs are touch-sensitive and allow the net ranking by a simple touch of the metal coated knobs."
For the euphonix gear (which i just discovered), i only found references in forums, but that's not my point.
iPod-style rotary sensor is not what im looking for, because you need to know what you're doing while you play music, and as every musician, you do not always look what you're doing if you know that you're doing it right : so all you need is a tactile feedback, eg a knob that you can grab and feel under your fingers.
Why are endless rotary encoders cool ? Because the control surface communicates with your computer, by midi or usb, in a way that if you move a pot on your control surface it makes a change on your computer. But what happens on the control surface if you move a parameter on your computer ? Nothing. So we need a feedback, mainly because we often use the same knob to do several things, depending on the context of use. So after establishing a feedback loop and for the computer and the control surface to stay synced, there are 2 solutions :
- motorized pots : ;D expensive but cool
- an endless encoder and a led ring around the pot telling you what is the actual value
(I told you i was planning to build a midi device to keep my question simple, but actually it could do OSC as well, which is not limited to numbers between 0 and 127, but basically between what you want and what you want
That's why i'm really looking towards endless rotary encoders.
I want them to be touch-sensitive because i need to trig some functions just by touching the knobs and not having to turn them.
My friend agreed today to open his Neuronium so we can look inside for clues on how it's made.
I think we could maybe achieve touch-sensitive rotary encoders by trying to replace the aluminium foil (in the playground page) by the metal rod of the pot... That would be a good start. I'll keep you posted on that.
