Wow, an Emulator for 10quid!!!! Well, er yea, as the next line sez, not quite... A number of people have very usefully posted up schems for the Powertran DDL, or the blooddl as I call it. But I have not seen any scans of the Patrick Shipsey (E&MM ) pitch/trig mod. So I dug out my copy and scanned it. This mod is very handy for it, download the pix for the info. Gives you pitch and trigger control, lushcore.

OK, here are the circuit diagrams / article, note the 4th diag is an Errata note that appeared in a later E&MM.

For those wondering what the Blooddl sounds like, you are encouraged to play QBF Check Some on the Automata 49 album at a very loud volume.
