So everyone knows about augmenting acoustic instruments with “preparations” or with electronic processing and such. But what about augmenting or preparing your controllers and/or electronic instruments?

Teenage Engineering has some cool stuff for the OP-1 with their accessories kit, but you don’t see too much of this in general.

This could be a thread for that kind of stuff!

First, my contribution creating a 3d print for using an arc like a turntable/controller:

After spending a bunch of time digging into turntablism/portablism in a kind of funky way (Kaizo Snare), I’ve had it in my mind to get into some digital turntable control stuff. I’ve eyeballed the Ms Pinky stuff for years, but given how nothing has been updated on the webpage is years, and I never got a response back when emailing them years ago, I’m sadly chalking that up to abandon-ware at this point.

I got to thinking about having something like an SC1000, but just using it as a controller (somewhat inspired by @okyeron’s experiments down that vein on Instagram) and remembered that I have a really high resolution encoder that sits on my desk all the time.

A few iterations later and I have this:

I’m still tweaking the tolerances and dimensions a bit, but the idea is that you can use it ‘as is’ as a larger platter for any arc encoder, with little cutouts for the LEDs. In the video I didn’t setup any LED feedback, but you can see in the pics how the LEDs still shine through if you’re using it as a simple encoder “hat”.

Then there are a couple options if you want to use it with a 7" record. You can put a bolt through the bottom (all the ones I had on hand were too long) and screw on a top piece to keep it secure. So kind of like a 45-looking thing.

Or you can put a nut in the bottom of the hat and screw a (short!) bolt in the top so it looks more like an SC1000. That’d be more of a permanent 7" hat setup where you don’t take the record on or off.

The print slides on easily and still grips it well (surprisingly). I’ve designed it in a way where there’s scrunchies underneath to kind of hold on a bit better, but it seems unnecessary really.

Once I get the design just right, I’ll throw it up on Thingiverse. I’ll probably make a patch that does something interesting with this, particularly since you can get two 7" on an arc 4 (one on arc0 and one an arc3), but it should work perfectly with all existing arc apps (where this kind of interface is used). From the looks of it @okyeron is working on something that this would be perfect for as well.
