I used 4148. It triggers OK with my ‘system 100’ LFO which is -10 to 10 volts but not with the drum triggers on my cvpal which are 5v. I think I used the schematic from juggle’s post:

> Yeah, it may technically be a reverse avalanche…but I had a hard enough time just fitting “avalanche” on there smiley Made half of another module last night. Still waiting on some components for things I really need to get a rack together (LFO, VCA, Envelope generator…) but I have the neutron I can patch through for most of that and the Tiny Dazzler “Percussive Noise Voice” was just too simple of a circuit for me to not try whipping one or two up. Wound up only whipping…

but I ended up making my own layout to fit in a scrap of stripboard.  
I’ll post the layout once I know it works.
