Post by Patrick ShirkeyPost by Michiel BroekPost by Patrick ShirkeyPost by Michiel BroekThis part works fine.
Post by Patrick ShirkeyDepending on which item is selected affects each output channel. Not
sure
about the simplest way to handle the multichannel output meters and
volume
controls though.
Maybe under a new tabs something like a number of boxes equal to the
number of bands (just like the compressor tab), and in each box a level
control, limiter control and level meters.
There are a few ways to handle this in the interface.
1: Radio buttons on the Limiter section
ex.
[all] [low] [mid] [high]
[ limiter controls ]
2: New scrollable tab in the upper tab panel
3: Tabbed controls for each compressor
4: Add the controls directly under the compressors by extending the
height
of the interface.
That would be a bad idea, see below.
Post by Patrick Shirkey5: New scrollable panel for the lower tab section with choice of 3 or 4.
Post by Michiel BroekAnd below that a slider with
crossover frequencies. That must be a new band splitter independent
from
the one for the compressors.
I'm not sure how this fits. Can you give a little more detail? What is
the
purpose of a second xover?
The second xover and outputs/limiters/delay belong to driving an active
speaker system. The crossover frequencies are different then one would
need for a multiband compressor. It is even so that once the extra
outputs are calibrated for the active speaker systems it is driving, you
normally do not touch any settings anymore.
The intention is to make the bypass on the compressors work too. At the
moment they are hardcoded because that was the easiest way to get a proof
of concept out the door.
Ok.
Post by Patrick ShirkeyPost by Michiel BroekDifferent is the three compressors, the xover frequency choice is a
personal taste and also dependent on the music style. This is more an
art and taste part while the extra outputs is pure technical.
Eventually, if the extra outputs, xover limiters etc were in its' own
application, it would be a solution too and for live use you should
chain mixer -> original jamin -> xover/limiters app -> lwo mid and high
amplifiers and speakers.
If the compressors are bypassed do you need a seperate application?
Not really. I attached a drawing based on the original drawing on the
website. The bottom part on the drawing makes me think that the original
limiter and output level is now duplicated in the new channels.
First some ideas on the extra output channels and how DBX uses them
If there are more that two bands, the lower band is driven by the
crossover using as a bandfilter. Only the highest output uses a shelf
filter. What they do in single band mode is to use only the high output
and put the shelf frequency probably at 10 Hz.
I think this is a good idea to make the system flexible, in single band
mode it is classic Jamin. To make it a two band system, the crossover is
something like 800 Hz, so the high channel is 800 upto whatever is
possible,, and the low channel 10 up to 800 Hz.
That system with its' crossover is being fed by the boost stage. (In my
drawing the original level and limiter is still in place.
Post by Patrick ShirkeyPost by Michiel BroekThat is the reason why I think it is logical to add a tab in Jamin where
all controls for the extra xover and output drivers can be placed. I
will try to make a diagram later this evening.
We should try to keep the signal flow. leading the eye down the interface
and then back up again to the output controls is bad UI design.
How about a collapsable panel for the multi channel band outputs directly
under the compressor panel so we don't add extra space unless it is
explicitly requested? We could also make the compressors optional by
hiding the compressor panel.
I agree that the screen should represent the signal flow, it should be
logical.
To make the best use of the available space there are some thing that I
find important. When I use Jamin I allways want to see the several level
meters in the compressors, the spectrum and so on so that you can see
what the signals are doing. It may be possible to show everything in one
view if you use popup's or some other idea to bring up the controls of a
part in the system. For example I don't need all the compressor controls
at the same time if I'm only adjusting the Low compressor. Only popup
the sliders when needed save a lot of space.
It may even be safer that the controls need to be activated to adjust
them. You call it a collapse panel, I don't know exactly what you mean
by that but it looks to me that for the user it has the same result.
It depends on what is possible to do, Jan is the expert on this subject.
Post by Patrick ShirkeyThere nothing specific to jamin online.

However what we really need is a step by step instruction manual for
jamin. If anyone wants to enlighten us how it is supposed to work that
would be handy.
Thanks for the links, it is much clearer now.
