Is there any way to get the cutoff on a filter (whether a VCF or an XMF) to really really close?

Basically, I'm trying to make a patch which has the classic 'pluck' envelope on the filter - to do this, I have added an ENV2 and routed that to the filter so it affects the cut-off. I've then added some positive ENV2 to the filter to give it that nice 'pluck'.

The problem is that even when the filter is closed totally (right down to zero), it sounds waaaay too open. I don't want to reduce the amount of ENV2 I have on the filter, as this will take away from the nice pluck I have going. But I DO want to be able to get the sound to close more than it currently is.

The problem seems to relate to the fact that the cut-off on the filter doesn't go down low enough. My JP8080 closes much more than Zebra does. So does Sylenth1. So does pretty much every other synth I use! Is there no way to set the offset lower in Zebra?

Thanks

maybe you have assigned some KEYTRACK to the filter freq ?

this affect the position of the filter cut off in relation to the note you are playing in your keyboard.

don't have Zebra...and i can't recall where is this parameter.

but since i remember trying that beast...i am sure you CAN close the filter...

so my best guess is that... reduce or cancel the FILTER KEYTRACKING

OK, after much messing around, I've found one possible way of doing it: minus velocity in ENV2. It's not exactly the way I expected to do it, nor is it a very good way of doing it; i.e. for those times when you want to make a patch when the filter is upwardly velocity sensitive (basslines, etc).

Surely there is a decent way of pulling the offset of the filter down?!

Good idea, but not quite good enough. I want the effect of the keyfollow on - I *want* higher notes to be more open than lower ones (though only by a touch).

Nevertheless, I did just try it, and it still does not allow the filter to close. Grrrr. All it does it take that nice emphasis off the higher notes and make the patch sound slightly more dull

It's true that, with 100% Keytracking (which is often desirable for a consistent effect across the keyboard), the filter cutoff can't be set low enough to cut a normally tuned oscillator completely. I agree it would be nice to have a wider filter cutoff range.

A couple of effective solutions in the meantime:

(1) Set the oscillator pitch UP two octaves. This places the oscillator output entirely above the filter cutoff. Of course you'll normally want to compensate by setting the master pitch down two octaves.

or

(2) Assign a ModMixer to the filter's second cutoff modulation knob; leave the ModMixer in its default state (constant value 50) and set the cutoff modulation knob to a suitable negative value.

Now that is a good idea! It's not ideal, but it does work!

@Paul, thank you very much sir!

@Urs: can I make a feature request? To add an offset knob, so you can reduce the cut-off frequency? This can be set to 50 by default, ensuring current patches are not affected.

Good idea/bad idea?
