Continued from yesterday’s article. Here are the switches I compared.
Mechanical Push Switch (Tactile)
You hear click noises.

Relay
There are occasional pop noises.

Analog Switch
Not bad but click noise intermittently happens.

JFET Switch
The most stable so far.

Other switches:
Attenuator type. Hard to eliminate leaks and pop noises.
Bipolar transistor switch. Sound is not bad but DC drain due to base current is unavoidable.
KORG MS10/20 VCA type. Not tested.
