Im trying to understand how this bass drum patch works,

I dont understand what is "excitating" filter resonance, and I dont understand the click sound.

Attach a scope~ to the line~ to get a better idea. The message "1., 0. 200" sends the output value of line~ from 0. to 1. immediately, which creates a click. (see also click~) That click excites the resonant filter in svf~. You can also pass that click directly to the output by putting a non-zero number in the number box labeled click.

2 the multiplier after svf~ has no value nor argument

Here is a sounding version of the patcher (commented):

1 you have no dac~ in your patcher

I didnt have a dac because it was a subpatch, i had a dac in another window,

Save the patch with the values in the numberboxes that is suited for a kickdrum sound.

(using som pattr object, so i also learn this)

Ive tried all variations on the numberboxes, and no sound...
