The aim of this DIY project is to use a standard USB midi controller with the POs. I want an inexpensive, battery powered, standalone setup (i.e. no computer) - just for jamming and just for fun.
Here's what I have so far:
I’ve put together the components on a breadboard and wired up the keys 1-4 on the PO and got it running using a USB host controller and an Arduino micro controller.
The controller is very simple and just takes key presses from the Nanokey and converts these to button presses on the PO.
In the video it is running stand alone with a battery powering the controller and a KORG Nanokeys mini controller attached via USB midi.
A few question that it would be great to get some input from:
- I’d ideally like to be able to ‘plug in’ the PO and once 16 wires are on it will be a bit messy - any ideas on a better way to wire up to the keys?
- I’m running out of control lines on the micro-contoller but if I had one or two spare what other things would be useful to control by midi - I was thinking pattern or maybe effects or sound?.
- I see a few people posting about sync’ing their POs to other stuff - would creating a PO sync click from midi clock be a useful addition? or would you want a midi clock from the PO tempo?
- Anything else that would be useful ? (there's no way I know of store patterns without accessing the PO firmware which I’m we can’t do without the help of Teenage Engineering)
If there is any interest I’ll post details and code when it’s all finished for other DIYers.
