Re: Programmer/Sequencer project

Wow,

thanks for getting back so quickly.

Two more questions, if I may. Q5, below sounded dumb, but what I
meant was what is the voltage range (ie is it compatible with Doepfer
& A systems kit - I assume it is).

And Q6, is there a simple way to make the pulse out a trigger?

Much appreciated

Stuadh

PS - I've spent the last few months agonizing over which sequencer to
buy and here I find the perfect one all along!
