Nice vid but what the heck do the Tolerance dealymadoodles do?
Kept waiting for that.
This has been discussed at length by me, and others, on this forum.
The tolerance switch models the individual components in an analog signal chain. Even though two resistors may be rated at 0.1 ohm, one may be 0.12 ohm, the other 0.09 ohm. Random numbers used here as an example. The tolerance switch adds that random element to the emulation.
Craig has stated before on here "Why would you want that?" I can see both sides. An analog desk would vary from channel to channel, but in this digital age do we want that randomness?
At least if the sound of a desk varied from channel to channel, it would be consistent - e.g. Channel 1 sounds nice on drums, Channel 2 sounds "Quite warm", Channel 3 adds a little saturation. Whether adding it randomly has any use, you decide..
