Simple way to decay a sound https://electro-music.com/forum/viewtopic.php?p=454957#454957 I have build 8 steps sequencer using 40106, 4040 and 4051 (See attached schematics)

However I would like to make it more 'musical' by adding a decay for each note that is playing.

What is the simplest way to implement that?
Any suggested schema ...

I'll try 'm out!

I'm looking for touch gate / triggers to control the volume of the drone synth (several channels of tuned (and chopped up) triangle waves, so it is not a squarewave or digital source.
