200e

yasi
 this is great news ... i've always stayed away from this fearing damage
i feel like i got a new module! 
thanks
joe

            It's nice connecting outputs to one another. The pulses/gates are diode coupled (wired-

OR, some call it) such that everything works out just nice without thinking about it at all. If 

you want to think about it, then think the pulse outputs each have their own half of a 

voltage-maximum- selector circuit. to connecting two togehter makes a whole max-

circuit and so outputs whichever of the two pulse/gate outputs is higher. the pulse/gate 

signals themselves   have 3 states: low (nothing happening), middle (gate), and high (pulse, 

only lasts a little while, a few ms or so, there's a range in the spec I think..). so taking the 

maximum of two pulse/gate signals gives you gate whenever at least one has a gate on, 

and pulses get through whenever they happen on either input.



the CV outputs are all resistively coupled so connecting them to one another takes the 

average of the lot. there are some exceptions having to do with some of the circuits with 

LEDs showing CV output levels (266e outs, 261e mod CV, 259e mod CV..) -- these can act 

weirder than just an average, but nothing will get too hurt. if anything current 

consumption will go up dumping through the LED.. try messing it up, and if you can do it 

Don'll probably fix you up someday.. or I will or somebody



audio is resistively coupled too, so you can do things like patch outputs together to get an 

equal mix of each signal. 259's sine and final outputs can be connected to cancel the 

fundamental, for example



As for what's up with trying to combine pulses with the 256e, it's sample rate is too slow 

to reliably capture the short pulses. but just connecting them all up works fine. if you want 

to do things like forming different subsets of a few pulses (for example you have 3 pulses 

and you want one subset of two triggering one thing, and another subset of two triggering 

another) then you need a little active help. using a couple 281 stages as a buffers would 

do if you don't mind the delay.



If this all isn't too clear, I think I posted it all in different words once (or twice?) before, so 

try that. and if it still doesn't make sense write and ask me. or better yet, post here 

because if you didn't get it probably someone else didn't either. or best just try it out and 

see what happens. you can't mess it up. or if you can I'd like to know, and I'll help fix it.
