Just made an experiment connecting a 5€ joystick to control two different modules. Pins +5V and GND of the joystick go to Master I/O +5V and GND. VRx here is plugged to Wasp Filter CV1, and VRy is connected to VCO CV. I later tried connecting it to VCO MOD in FREQ mode and is much easier to control and sounds better. I might end up making a simple module with a couple of joysticks.
Here's a demo of the experiment:
I had one problem, though. The joystick can also be pushed as a button, and provides a SW pin. I tried connecting it to S&H TRIG but doesn't work. Nor with the ENV GT1. Connecting it to VCO CV I do hear a change in pitch, but very subtle. I checked the voltage and seems to be fine: 0V when open (not pressed), and nearly +5V when closed (pressed). Any ideas on why can't I use it as a trig or gate?

That reminds me that I also have two of those sticks waiting to be DIYed into something  You can also use the joystick as an Attenuator for any kind of signal. Just patch anything else into it instead of the +5V. Or use X for 5V constant voltage and Y as an Attenuator. You could also add a 5V switch like on the 2ATT module. Not sure what’s the problem with your gate button though. It should normally work as you suspect. Edit: you can also try to remove the spring in the joystick to not make it return to the middle position automatically. |

Hmm, the switch thing is weird; because when you send 5V to the VCO CV it should jump 5 octaves! Same with the envelope trigger. is there a resistor somewhere in the trigger line? You could take a wire connected to 5V and check the behaviour. Indeed I was thinking already about a joystick module and have these guys already lying around but no time yet to make a module. Great to see you have been faster ;-) NightMachines: Great hint with the spring, because I was not happy with the return-to-zero mechanism... thanks! |

I think I'd mentioned something like this a while back...combining something like a Wavestation A/D joystick (little nub of a thing, no springs) with a joystick processor akin to Ladik's J-011 ( ladik.ladik.eu/?page_id=86 ) that can allow for more complex control functions out of the X and Y voltages. I like this "circle pad"-like stick better, though; it fits under the finger nicely, very much like the Nintendo circle pad on the 3DS, which it resembles. |

You could take a wire connected to 5V and check the behaviour. Not sure about the resistor, I'll have to check, but the multimeter displays nearly 5V from pin to pin, so I guess that's not the problem. It might be the cable I'm using or just a loose connection in the extender. I'm away from the synth now, but I'll check as soon as I have it around. Edit: you can also try to remove the spring in the joystick to not make it return to the middle position automatically. Great hint indeed! I'll definitely try that. Thanks!

Removing the spring works well. However, it can make them too loose, especially if you add a substantial stick handle to the joystick. I'm planning to dismantle one (again) and try adding some foam to add friction so they stay in position once you stop moving it. Perhaps a more elegant solution might be to simply roughen up the rotating parts with a file to get more friction.
also, it is fun to turn the joystick upside-down and attach a ball on a string for some real-world physics modulation effects. I never got around to this, but I want to try that again with magnets to get some chaotic attractor things into the music.
something like this...

lol, that'd be nice to hear.
