In my experience, you need to enable the reverb in the qsynth GUI, turn
up the level, and that will set your maximum reverb level for the synth.
However, CC91 should still control the reverb level per-track, with some
amount of reverb level variance provided by the per-instrument/preset
reverb levels contained within the SoundFont itself. The same holds true
for the chorus.

mhh I'm not really sure about that, but I see a use case for it. It 
seems the Qsynth controls "mimic" the fluidsynth parameters, but ignore 
channel events.

Yes..

I'd also point out the possibility to route the audio output of the 
synth to many of the (nice) reverbs available (LADSPA or whatever (or if 
you use fluidsynth directly as a synth in Rosegarden just add it to the 
track..)

Thanks for looking into this, Lorenzo.  QSynth does have its own reverb 
and chorus knobs built into the GUI.  It makes a certain kind of sense 
that they would implement these as global parameters and ignore per 
channel controllers.  Otherwise you could send conflicting messages on 
the channels and have your GUI reflecting one thing and your synth 
engine playing something entirely different.

Looks like using fluidsynth from the command line is the way to go to 
get this to work as expected then.  That's good information to 
disseminate.  Thanks.

My version of Rosegarden (14.06) is correctly sending a controller 91 
event (the reverb controller in General Midi) when the 'Reverb' knob is 
turned, so my guess is that the synth / soundfont you are using isn't 
responding to such controller.

Qsynth seems to completely override this and the only way to add reverb 
seemsto be using its own controls.

On the other hand fluidsynth (from command line) responds correctly to 
the reverb (and chorus) control changes.

[Rosegarden-user] Reverb for a specific MIDI track

2014-04-28 Thread Victor henri




Hello Michael

Thank you for your answer. 
Indeed, I forgot to say that I am using Qsynth (with my own soundfont bank, 
that looks like the Fluidsynth soundfont).
If I understand you well, this issue is very complicated to solve? Should I 
search in Qsynth config how to solve it? Or are you aware of an alternative 
software to use instead of Qsynth, that would solve the problem?

Fot the record, Rosegarden version in Ubuntu 10.10 is 13.04. 

Thank you

Victor

er... I think I was the one who contributed the set of rgd s for
the M3 (oops) but it was my first attempt and I didn't know that
the format went beyond the voice program stuff at the time so I'll have

We have a bunch of them.  Maybe the guy who made yours just goofed.  If

Re: [Rosegarden-user] Reverb for a specific MIDI track

2014-04-27 Thread chuck elliot
Hi,
since posting the question I did have a look at the Control
settings in Studio/Manage Midi Devices and found the relevant
parameters (I know! I should have done this before posting! ><). 
It seems that Reverb control on the M3 is set using
a value of 93 and this was allocated to Chorus within RG.
I swapped these values and (after a restart) the Reverb 'knob'
now controls M3 Reverb (Result!).

As you say Michael these things are device specific and the
developers can't be expected to cater for any more than GM.
However, maybe there is scope for including some of these
settings in the Voice Program files (*.rgd) that are contributed by
users. That way it gets covered to the extent that is felt
necessary by the user base, without such a huge effort on the part of
the developers (to whom great thanks are owed for a great program).

Of course it could be that there is so much variety in the way
that manufacturers implement these features that even this would not
be a practical solution.

Best wishes,
Chuck.

Re: [Rosegarden-user] Reverb for a specific MIDI track

2014-04-26 Thread renedrive
It would be nice to have a way to change the MIDI commands output.
A kind of patch panel that allows you to edit a MIDI command output. in
this way the GM standard reverb control command could be translated into
a custom command to any MIDI instrument, reading commands directly from
their user manuals.
Better still if, as some other programs, if Rosegarden could learn
"listening" to this command maybe present to the instrument panel, in
other words, the possibility of putting Rosegarden listening for the
reverb command (or any other), make changes to the reverberation command
of the instrument, and see Rosegarden using this new code, customizing
the configuration, for the reverb command for the specific instrument.
The ability to save the setting and perhaps be able to share the
configuration file of a particular instrument would then be the maximum.

But maybe I really wonder too, maybe you will understand that I am not a
developer.

The latest Rosegarden you can get through Ubuntu is probably a bit old, 
but it is unlikely that the age of your Rosegarden is your problem in 
this case.

It is most likely that whatever you are using to reproduce MIDI either 
does not understand reverb or handles reverb differently from expected. 
  It could be on a different, non-standard controller, or it could be 
something radically wild like the Korg M3 example asked in the other 
question.

The place to start, therefore, is to establish what you are using to 
reproduce MIDI.  Typically this will be QSynth with the Fluid soundfont, 
but there are dozens, even hundreds or thousands of other possibilities. 
  Unfortunately, this particular issue is immensely complicated.

In general you want to play with Studio -> Manage MIDI Devices... and go 
make manual edits to the controller setup.  In this specific case, 
however, I went and grabbed the manuals for this beast and 20 minutes 
later I'm scratching my head.  The words "reverb" and "chorus" don't

Rosegarden is not well suited to control such a beast, having been 
designed with General MIDI in mind.  It isn't that Rosegarden is only 
suitable for GM, but GM is the model we had in mind when we designed it, 
and anything that is massively non-GM just doesn't fit the model very 
efficiently, and falls into a big gray area.

I don't know what I could manage to do with it if I had one.  I'm sure I

for me to figure out without access to and experience with the actual

Hi,

I have found that the reverb on my Korg M3 is
controlled by the "Chorus" control in RG and not
by the "Reverb" 'knob'.
Is there a way I can correct this?

[Rosegarden-user] Reverb for a specific MIDI track

Hello

I would like to apply Reverb to a single MIDI track in 
Rosegarden. There is a knob for that for each track but it seems not 
working. 
I use the last Rosegarden version available in the repositories of Ubuntu.
Any help?
