I'm thinking of attaching switches and various sensors to create CV signals for the AEModular. I've got a lot of them pulled from some robotics projects to experiment with. But to do so I need ground and +5V. I know that the Master I/O has both: but only in R3. I have an old R2 and cannot afford an R4.
1. Are there any other common patch points which expose ground?
2. I have a 4ATT-MIX with two +5V patch points. If I attach (say) a simple switch via a voltage divider to +5V, is it likely to pull +5V down enough to cause problems for other units on the bus?
3. I'm thinking of attaching a Sharp IR sensor (such as www.pololu.com/product/136) as a special kind of pot. The Sharp IR has a draws current in bursts of up to 30 or 40ma. If this is attached directly to the 4ATT-MIX's +5V, is it likely that the bursts would cause problems for the bus?

Regarding the Sharp IR that draws current in bursts of up to 30 or 40mA: Should not be an issue; I'd recommend a fat electrolytich capacitor in your circuit near the sensor, that buffers these bursts; otherwise they can be audible as clicks and pops. And the bus cable is the best source for +5V / GND; you can plug in breadboard cables too.
