If you're like me, you've probably been working with PAIA for years. So, you began with the good old trimmer type keyboard. As PAIA grew, you've grown, and agreed with PAIA's better way of doing things. You now have a modern up to date Digital Keyboard. Now you probably think you have a useless -8 Sample and Hold, right? Wrong. This modification will change your line of thinking! This simple circuit will give you a very useful Sample and Hold module.

Start by constructing the trigger circuit on a small pc or perf board. Next, modify the Sample and Hold board by shorting out R15 in the old trigger-gate circuit. Then install the new circuit.

Put the voltage you want to Sample and Hold into "E", from any source (LFO, AR, ADSR, etc.), trigger it using the keyboard or any other source and you have a useful module!!
