Simply untrue, the market is VERY competitive.

It's not what I do. And if you think a 'good to listen to' reverb algorithm is
simple (not echo), you're VERY mistaken.

"The DSP (effects) section is a marvel of compact design. There
are eight different reverb/delay treatments made accessible
from the rotary controller with a LED beside each one to show
which is active. But this section has more tricks up its sleeve, as
we’ll see when we look at the four LED-illuminated buttons to
the right of the rotary.
Of the four switches, the first is simply on/off for the effects
section. The second puts the section into reverb mode, as
explained above. The third puts the section into delay mode,
at which point the rotary adjusts and displays the repeat
time between 10-720ms. Finally, the fourth switch introduces
regeneration, or the number of repeats you get before the
echo disappears completely. In this mode, the rotary controls
the regeneration level – up to 90%, which is almost infinite.
This is a very neat system that is much easier to use than
it is to explain. It also sounds very good. If you can’t find a
setting here that sweetens your voice, you might be better
off learning the banjo! There are also two level controls in the
DSP section. One controls the effects level in the main mix, the
other the level in the monitor mix.
Round the back, there is a socket for a footswitch to turn
the effects on and off. This is a useful inclusion because it
sounds really stupid if you are talking to the audience between
numbers and there is enough echo to call in an Alpine goat
herd."

I know something her husband did (Alison was a very good girl-friend of mine) that might well meet with her serious disapproval.
Nothing for me to feel guilty about.

Only if he's buying such a piece of kit. The market generally likes reverb
to be available along with graphic equalisers (which I'm less keen on
since of its ability to **** the sound up wonderfully when abused) for
instance.
That doesn't mean I never design a graphic equaliser. In this case MY
opinion is irrelevant.
Purist higher end desks never have either installed since the user can
select his/her preference of reverb/equaliser form many brands and models
of rack mounting 'outboard' kit.

Yes. Fitted. The diodes only helped. Fast 30~40V, (external) incoming
edges through the Cgd's caused lock-up of one section, quickly
noticed by the others, nett result a few uS of chaotic transient
oscillations (and Cgd pumping) as they all settled into step. A few nH
of series strays didn't help either. A LF 'dominant pole' fixed the
problem but the setup was numb out beyond a few kc hence useless as a
'load'. Did the job at the time but would rethink next time round.

Sorry Michael, but you've clearly never been a sound mixing engineer. I have (lots) as
well as tech, equipment designer, project leader, installer, coder for the software, you
name it.
Just a ROOM has natural reverb. Then think Cathedrals. Reverb is everwhere. Acoustic
singers often rely on it.

The whole audio industry disagrees with you. I doubt you've even heard a
good modern reverb or ADT. It's not springs any more you know.

You speak largely from a position of ignorance. Many early reverb effects were cruddy
and that's being kind to them.
It's a shame you're the other side of the pond or I could get you into some good studios
or live venues and you could see/hear for yourself.

How much DSP code have YOU written ? I can tell you, when I took it on I
though it would be a challenge. Not writing the code per se, that's easy
enough but making it sound so right that reviewers glow over it.

Opamps have CMOS output stages. Couldn't see a schottky threshold helping.
Problem looks simple enough to sort (trivial even!) but have picked up a
sixth sense over the years about the time and effort involved on 'working in
the margins', so am not averse to calling a halt.(Unless of course a
customer is paying for the investigation

LOL, I can tell you that you have a hard time reading between the lines.
I did a project years!!!!!!!!!! ago using a ISA bus card in a 486
computer that sampled up to 500K, this was used for harmonic spectrum
analyses reports using DFT/IDFT which later on was translated into
a FFT with coefficient tables. the PC was 100% dedicated to this
application under a DOS os with the time consuming code written in
ASM to help things along and the rest of it in C using custom graphic
code, also written by me..
The code had to isolate signals, remove unwanted signals etc..
Oh btw, I also wrote some 8 Bit FFT code in a uc controller for other
lesser important usage's for things like transferring video images over
low band radio via audio spectrum.. Then adopted that to a windows sound
card which really has it's fall backs with hardware quality and OS issues.
Your reverb code does interrest me just like my said above project
does not interest you and most likely every one else that is reading this.
