Well here is a quicky mod of your original circuit that should have much
The audio oscillator modification fixes the high frequencies that were the
main problem. The resistor cap values may be changed to suit. I suggest
much larger resistors and smaller caps to reduce power.
The pushbutton input now gives one clean pulse to start the sequencer. A
logic start signal can be coupled via the diode.
The 3 diode OR gate is changed to give a good logic signal for the tristate
It should be much better behaved so that there is no disturbance of the
sequencer operation allowing for more control resistors.
As you have probably found ourt by now, there are plenty of designs that
make noise but only a few are pleasing to the ear and even fewer are worth
listening to for any length of time. Those are the keepers.
I have no idea what your circuit sounds like so a small (?) audio file to
the file section might be nice.
