A couple of basic questions about the ACE vcf

[Aevor]

So I'm trying to learn the basics of synthesis and of ACE at the same time there's a lot of questions but the most pressing at the moment is about the functionality and routing of the vcf's.

Both the LP and HP filters have their own outputs, but is LP the one routed by default to the main cutoff-knob? How do I access the HP filter? Do I have to route it somewhere? This is probably obvious somehow but I'm just totally confused

Thanks!

There is just one cutoff knob, so whatever you set it to, that's the cutoff frequency for whichever filter type you select for any of the two outputs.

What ED said. Simultaneous outputs for different filter types with shared cutoff and resonance etc are commonplace in the modular domain, where ACE draws heavy influence from.

But if I patch the LP-filter straight to the VCA,I get the exact same effect as with no patching. When I patch the HP to the VCA, then the Cutoff works as a HP. I mean I don't get a HP without patching? If the BP and the HP would share the same Cutoff knob would it then be a BP-filter?

The LP filter is normalled to VCA1 ie pre-patched, so overwriting it with a direct connection won't make any difference. If you want HP, yes you have to make a connection, either to VCA1 to overwrite the default LP connection or to VCA2, where you would then have both LP and HP outputs simultaneously.

above of the VCF module and left of the fx section there are the 2 VCA modules
they are normalized to ADSR1 input and the left (aka "VoiceMix1" aka "VCA1") to VCF1
and the right (aka "VoiceMix2" aka "VCA2") to VCF2

example how to use VCF1-HP only:
1) set the volume of VCA2 (VoiceMix2), the right module, to 0
2) set the volume of VCA1 (VoiceMix1), the left module, to 50
3) connect HP-out of VCF1 to the VCA1 input, where it is labeled (normalized) "vcf1"
4) now you should hear the HP/BP/BR output of VCF1

hth

p.s.:
the VCA section is explained in the manual on page 33
p.p.s:
imho an image of the VCA section in the manual would be helpful for beginners in re orientation...

[Aevor]

Thanks!

Yes I've been over the manual like crazy but still some things are not so clearly explained there.

I'm always willing to improve the manuals: Which particular features aren't explained clearly enough? Fire away!
(BTW I'll add that image of the VCA section)

[Aevor]

Well I think the main confusion here for me was that it doesn't specify in the manual that only the LP-filter is hardwired into the filter architecture, i.e that you have to patch the HP in to access it. And at first I was wondering whether the top row controls on the filter are for LP and the bottom row for HP.

[Howard]

Thanks - I'll add that info.
Re the top row of controls in the filters: There should be no confusion there as the knobs are clearly labelled and the image in the manual is annotated

the features are explained great
imho it is just the missing image, that - even me - was
curious about which section of the synth it was about...
