Patch Sockets 

Treadstone  features  a  generous  array  of  eurorack  style  patch  sockets  the  allow  you  to  further 

extend the range of sounds possible by doing some simple patches.

EG Trig 

This is a trigger input for the EG. LFO Square can be patched here to trigger the 
EG  or  use  an  external  trigger  signal  from  an  analogue  sequencer  or  eurorack 
modular.

EG Out 

This is a EG CV output. Patch this to places such as pitch or pulse width.

LFO Triangle 

This is LFO Triangle CV output. Patch elsewhere, to pitch CV in for example.

LFO Square 

This is LFO Square CV output. Patch elsewhere, to pitch CV in for example.
