Is it possible to do Sub EQ with low/high shelf filters, or only peak like it is now?

Is this beta plugin available for the 2x4 balanced units?

Can you please allow normal peak adjustments to go down to 25hz? Not being able to adjust the Q above 3 in those ranges makes some things hard.

Hi Nyt,
according to Devteams post, limited Q is one of the required limitations to get things working. Thus I assume that higher Qs will unfortunately not be possible in this frequency range. looking forward to Devteams reply...

Hence the request to allow normal peak adjustments down to 25hz instead of limiting them by the slider to 50hz.

Um... so do you lose a filter each time you set a center frequency below 50 Hz, or just once?

Is this update reversible?

To answer my own question (I installed it on a "sandbox" machine), you lose one filter per channel.

On loading a configuration that has "Peak" filters set below 50 Hz, they remain turned on, so presumably they still work. However, changing any parameter of the filter sets the frequency to 50 hz. Alternately, changing the filter type to Sub_EQ sets the Q to 3 (assuming it was higher, which they always are in this range).

I thought the big problem was with shelving filters. They are not affected in this update. Is the issue noted in the first post solved without having to use the "Sub EQ" filter type?

Ok, in answer to questions and comments below.

The choice of 50Hz and limited Q comes from the reasoning that we simply wanted to play safe with a stable system in various configurations. I don't see changing this for the SubEQ else one of you will figure out a way to take it in an unstable position and reopen that can of worms. There are many reasons we want to close this case and call it a day:
-We'd so much prefer develop new solutions, firmware upgrades for IR, new plug-ins.. etc than waste too much energy on something that is to us only 1% of the potential of this product.
-There are many users who bought this platform who could voice they'd prefer we take that time to develop features for other applications it is intended for (multiway speakers). They have a voice too and it's a community where people need to be considerate of others (at least we are). Hope this makes sense that we will have ONE solution! :-)

What could be done would be to leave the ability for the PEAK filter type to go down to 10Hz and you take it with the understanding that maybe it's not as accurate as SubEQ. Then if you rather use a more accurate equation, use SUB_EQ subset instead. That's the only medium I can think off to keep people happy and not burn resources on many solutions... What about this?

As for John's question, only the parametric EQ was modified. Shelving was not modified.

Hoping this clarify,

Yes, I like the solution of letting peak go down to 10 knowing that it may not be accurate, since 50 is too high and it still worked below there a bit.

Tony - it's up to you what you do, but I think this beta 1 release is unusable.

John,

Not Tony answering here but we do want to find a solution, just want to close this issue that's all.. :-)

Didn't the proposed solution would work for you?

I'm not sure I entirely follow, I wasn't the person complaining about sub-20 Hz performance. However, I do think that limiting Q to 3 below 50 Hz would cripple the product. I don't even know how these things happen - I guess that's "the power of the Internet."

I'll try to do some of my own measurements in the next couple of days.

Im definitely confused about this discussion and how it impacts MiniDSP overall.

Is this a software/hardward issue just for the 2x8/4x10 products??

Does this software change "limiting Q to 3 below 50 Hz" effects all the other plugs in??

How does this impact the PWR-DSP units and their ability to EQ below 50Hz??


I can definitely see this as a huge road block for everyone buying and using the MiniDSP for subwoofers, which I think is a fairly substantial market.
