TTSH Gatebooster
The TTSH needs Gate AND Trigger signals with 10/11Volts, otherwise it dosnt work as designed in usage of the AR/ADSR.
here the simple Solution:

for version with midi implant connector run a 1M resistor from ground to Pin3 of TL072 fix the issue.
for Rev.1 use the speaker holes to mount a bracket
for rev.2 :
drill 2 holes in the pcb and mount brackets with woodscrews, cut the TIP/HOT traces for 3 jacks on pcb, use one ground (you dont need 3 grounds) run wires from gatebooster to the tip from the jacks
take power from a module section (there are 6 solderholes, 2x3 rows - test with a voltmeter the voltage output/polarity) run powercable to the gatebooster.
not shown a other Solution: connect the gatebooster input with a cable from the GATE Input jack from the ttsh. (its needed to cut the trace from the S/H/Gate switch)
