MIDI file volume - please help

[Neil Hindry]

I wonder if you can help me.

I have a couple of MIDI files that I want to use on my phone but when I play
them the volume level is very low.
Obviously I can increase the volume level on my phone but that affects
everything rather than just that the quiet MIDI files.

Does anyone know of any free software I can download that will allow me to
increase the volume of a MIDI file and then save it again so that the MIDI
file is now saved with a higher volume level?

Is there any other way I can achieve this?

I hope you can help me.

I appreciate any help or information given.

Thanks!

Anvil Studio is a program for multitrack recording, composing, and editing
of music using digital audio, MIDI, and sampled percussion sounds. Audio
effects include delay, pitch change, volume change, filtering, and reverse.
Anvil Studio is designed for people who want to perform music with MIDI
equipment, or record and edit music with MIDI and audio equipment or with a
computer and sound card. It allows you to record and edit a single stereo or
mono one-minute audio track, and create unlimited MIDI tracks. Optional
accessories allow you to record and mix up to eight stereo/mono audio
tracks.

Version 2005.03.09 features the following enhancements. When recording
stereo audio, two VU meters are shown for left & right channels.
View/Metronome now lets you assign a synth/bank/program. You can now
double-click on PlayList (.PLY) files to launch Anvil Studio.

The truth is one, you must accept it. Reality is not a point of view, since
if everything was a point a view, then the theory that everything is a point
of view, is just a point a view and not something real.

There's a prog called mididsm, you can get it from here

http://www.midipage.nl/uk_down_soft.html

"midi file dissassembler/assembler"

It converts midi files to text, which you can edit, and reconvert to
midi.

In particular, in the header of each track...........

|Program | chan= 2 | pgm #= 1 Grand Piano
|Controller | chan= 2 | contr=Volume H | value=112
|Controller | chan= 2 | contr=Pan H | value=127


(Then the actual notes for track 1 start.....)

the line for controller value=112 can have a value between 0 and 127
also if it's stereo and yoou want it to be mono you should change all
pan=?? to 63 (central)

I'm very much a muppet at this, have a look at

for all you need to know and more

I'm afraid your suggestion won't help much, Mike. It's quite common to
adjust the volume of individual notes and sections throughout a tune, for
fades etc; at best the information that you are pointing to in the file is
the base or initial value. There is also a second value that sets effective
volume to a fraction of the first, plus a second set of controllers for fine
control over the volume levels (and other settings). Some of these are
sound-card dependant, ie depend on the implementation of the midi GM
standard by the soundcard. Furthermore, there are at least two other
significant file syntaxes and structures: XG and GS.

Any midi sequencing software should allow changes to the base level of one
instrument. However (and here's where it starts to get more complicated),
the actual sounds that are rendered by the midi file often contain multiple
sounds for different intensities and volumes as well as the different pitch
of note. Changing the volume of a track in a midi file can change what you
hear when you play the file, in other words, not just how loudly you hear
it. And since every soundcard is different, and there are "soundfonts" or
software versions of the instruments that can be downloaded and used by
various soundcards and software, it's impossible to predict the outcome of
tinkering with any given file in this way.

The best way of handling the volume of MIDIs is to adjust your volume
control.
