Ok, eventhough none of you fiends said yay or nay I've now added it:

Changes:

- Added optional automatic make-up gain for downwards compression and upwards expansion. The out-knob then works as an additional gain (set it to zero with ctrl-click for neutral gain).
- Fixed overall gain (it was only correct when high/low set to pure high OR low, not when mixing the two bands).
- Minor tweaks which I don't quite remember now.

sweet.
Did you fix the ""ahead" pitching the signal when turning the knob" bug ?
Is there more presets ?
Is it opto/vca ? What is the latency ?

The eq is good, but sometimes it crashes... mainly when i move one of the points drastically... It works fine in "static mode" anyway. And is efficient !

Not a bug, that's what happens when you fiddle with the delay time in a delay. Either that or abrupt jumps. I'm not sure I see it as much as an issue as something that can be used as a funny effect. It's not like you automate it unless you want to do weird stuff. Feel free to have a different opinion though

No, and they are so-so atm

Most of them are way too aggressive for many types of applications

Sorry about that.

vca. When ahead is set to zero there's no latency.

I know, I will have to smoothen the parameters and make sure you can't make the filter unstable. Could reduce the CPU usage to half of what it is now as well, but then I'd have to introduce a one sample delay and mess up the schematic a bit

When testing on a bit more varied material I noticed that with out set to zero and using the automatic make-up gain there's a lot of overshoots resulting in distortion, should I make the make-up gain a bit more on the safe side? It's easily done...

ok. Not a real problem. Just unexpected.

Vca : i had guessed it but wanted to be sure.
Zero latency is fine.

One sample delay is a price i agree to pay to have cpu usage reduced by half !
it worth it imo.

Hi Stefan,

Just gave these two a try in Cubase SX 3.11 and I got the Compressor presets coming up in the preset list for the Eq. Perhaps Cubase has trouble distinguishing them for some reason.

Just on the GUI - a couple of suggestions:
Change attack/release time to miillisecs
Find a bigger font for the parameter value and a higher contrast between text and background please.

If the compressor is dual band like Endorphin (?) perhaps the frequency knob should be called crossover?

Regards,
Eg

All good suggestions, will see what I can do! And indeed it is a dual band one like endorphin

About the presets in the EQ, that's just me forgetting to remove them when copying stuff between these two. Didn't think about that the host would expose them (which it ofcourse should do however)

Hi Stefancrs
How is Nildon going?

stefancrs · Post by **stefancrs** » Tue May 09, 2006 6:53 am

Uhm. Well. When I'm not busy doing these two

Totolitoto · Post by **Totolitoto** » Tue May 09, 2006 6:56 am

can't wait!

Question:
The auto-gain works as it should, for the sustained part of the sound. But when using longer attack times the overshoots easily result in distortion. To me, when trying out various methods, it seems like most of the time you want a mixture between compensation for sustain and transients/peaks. Would it be a good idea to have a knob that would go from no automatic gain compensation -> sustain compensation -> peak compensation ? Otherwise I could have a few different modes to select between, but I'd really rather not have more than off/sustain/peak/blend which wouldn't be quite as flexible.

Input on this please

hey nice to see the baby growing, will test it as soon as my audio puter is working again (two power supplies fused last sunday

)

Both seem to work fine in Adobe Audition 2, thanks for this....
I think its time to shell out some dough for synthmaker

stefancrs · Post by **stefancrs** » Tue May 09, 2006 1:54 pm

That'd be cool

I'll put up the schematic as well as soon as it's mature enough. I really want the functionality "nailed" first, so I'd really appreciate if you could give me any feedback on the issue raised in my previous post
