Spire Synthesizer

[surreal]

Thank ypu very much

Are the lowpass filters always open (at least a bit), even when cutoff is fully closed, or am I missing something?

If you mean when you create a preset from the init patch, then normally ENV3 is initially set to modulate Filter 1 cutoff.

Yeah, I know that. What I meant was, when you close down the cutoff completely in every way, you still hear a sine wave when you play the really low notes.

Because the lowpass is 24dB.

Because the lowpass is 24dB.

I don't know how this has anything to do with my question, but never mind.

You're not wrong I'm just testing it now C3+ it's silent but go down towards C0 and it starts to output volume

This.

Why?

It's probably a bug (i can confirm it). You should report it to the devs.

If you init Spire, any choose any filter, keep in mind that Cut 1 is automatically pre-assigned to Env 3
However if you remove Cut 1 from Env 3 mapping, and let's say choosing "Perfecto LP 4", and crank the Cut all the way down (0), the Sawtooth might not get passed through the filter at Mid - high keyboard range, but it would definitely "leak" a little bit in lower octaves.

Any of them present here at KVR?

[chk071]

Yeah, but, you will have better luck here: https://reveal-sound.com/plug-ins/spire ... e-base/220

They rarely look into issues in their KVR forum.

Oh. So it's actually normal?

[phreaque]

Oh. So it's actually normal?

Let's say it's just Spire own characteristic. It might be differ than other synths, but it makes sense, LP filter usually cuts lots of high frequencies while allowing (some) lower ones to Pass.

[Ghost Dog]

It .... could .... be, but i can't really tell whether it is, or not.

Maybe it's just the way the filter is tuned (it allows for some low frequency signal to pass, whereas the filters in other synths would cut everything off)?
