hello all,

powering through my DIY module backlog as i am, the following idea hit me -
how easy is it to make a swiitching module that uses a gate to switch a
relay
the relay is attached to tip & sleeve of a jack, and can be used for example
to switch in bypass mode on the MOTM850, but more importantly, various modes
on my roland vocoder, the bypass on my space echo etc etc

i assume the trick is to select the correct relay, then gate it via a buffer
circuit, and attach the switch section of the relay direct to the jacks -
any other idea anyone..?
also i asked this before, and lost the reply - does anyone have any stand
alone buffer circuit designs they can share..?

cheers
paul b
