Thx.

This Class is useful, If it can render direct to images is wonderful

Hi, i get the above error when trying to parse Midi file via
$tab = new PhpTabs(public_path("midi/".$filename));
error is at
stdtabs\phptabs\src\PhpTabs\Reader\Midi\MidiReader.php

• Create percussion strings
  *

  • @param int $stringCount
  • @return array
    */
    private function createPercussionStrings($stringCount)
    {
    $strings = array();

  for ($i = 1; $i <= $stringCount; $i++) {
  $strings[] = new TabString($i, 0);
  }

  return $strings;
  }

may i know what exactly is TabString? thank you

Related to #7 (comment), some more recent versions of Guitar Pro file formats should be supported.

Hi. I try to use the library to get info about midi files.
How I can get duration of file?
For example, the duration of this file is 5:52

I saw the tutorial https://phptabs.readthedocs.io/en/latest/examples/ex.calculate-measure-and-beat-durations-in-seconds.html but it something strange for me. Because the resulted duration so small, or so big when I tried summarize all beats/voices.
Sorry, I'm not a musician)

I have good idea, I love it. But may be your didn't parse capo fret data from gp file, I hop you add it

First of all, thank you for your Library! Very nice job, mate!!

I'm working on a proprietary tablature format and I'd like to convert it to phptabs format, in order to export to midi and gp5. I already mapped some of the structures like Channel, Note, Voice, Measure but the save function is still throwing errors. I'm probably missing something. So I'd like to ask if you have a minimal example of a tablature written from scratch. That would be very useful!

Thanks again.

Regards,
Chrystian.

Music in 6/8. I tried to plus all notes length but it alway # with 2880 length of measure

Hi Landrok,
let me wish you a happy new year first! May it be as productive as the last one. :)

Quick question from my side:
I'm updating my website to use the current version 1.0.4 of PhpTabs. In former versions it was possible to check if an gp5-file has been parsed successfully by checking:

$tablature = new PhpTabs("file.gp5");
if ($tablature->hasError()) { ... }

In the current version this method does not exist anymore. Which way is intended to check if a file has been parsed succussfully?

Best regards,
MrChros

Hi, Looking at the phptabs, lot's of work on this project, and well coded and done.

I am looking at the methods, and I cannot figure it out how do I walk trough a partiture, I am trying to generate guitar tabs, eventually vextab file to be played in vextab player.
Thank you.

when i try the following, it just changes the strings

$filename = '/GuitDaEMOns/CIID-Heaven&Hell-BibleBlack-Full2exp.mid';

$tab = new PhpTabs($filename);

foreach ($tab->getTracks() as $itrack => $track) {
    if ($track->getStrings()[0]->getValue() !== 0)
    {
        $tuning = [36,41,46,51,55,60,65];
        $count = $track->countStrings();
        $diff = $count - count($tuning) + 1;
        $j = 0;
        for ($i = $count - 1; $i >= 0; $i--)
         {
            $tabString = $track->getStrings()[$j];
            $tabString->setValue($tuning[$i]);
            $j++;
         }
    }
}
file_put_contents($filename.'.gp5', $tab->getTablature()->toGuitarPro5());
echo $tab->getTablature()->toAscii();

the strings change tuning but the notes don't change, the frets stay the same

The KeySignature never seem to get set with mid files.
If always returns key signature: 0

Hi, I'm trying to update the names for some midi files as when I import them into my DAW, they show a standard name and it's tough to know what is what.

I'm doing this:

<?php

require_once 'vendor/autoload.php';

use PhpTabs\PhpTabs;

$file = $argv[1];
$mid = new PhpTabs($file);
echo $mid->getName() . PHP_EOL;

--

Each time the getName() is blank. If I use a gp* file, it seems to work fine (for example: https://gprotab.net/en/tabs/the-eagles/hotel-california works).

Here's an example of it not working for a Midi file: https://www.midiworld.com/download/3290 (Enter Sandman).

Thanks,
Hans

What time spend for this measure ?, how to calculate ?

I have recently tried the render function to ASCII format. It work very well, but I did not see an option to render only a single measure or a range of measures of a single track.

In order to enable such a feature I wrote an external function:

function PhpTabs_Render_Single_Measure(\PhpTabs\PhpTabs $tab_source, $track_number, $measure_number)
{
	// Create new Tablature, Track and copy Track name
	$tablature 	= new PhpTabs();
	$track 		= new Track();
	$track->setName($tab_source->getTrack($track_number)->getName());
	$tablature->addTrack($track);

	// Copy Strings
	$strings = $tab_source->getTrack($track_number)->getStrings();
	for($i=0;$i<count($strings);$i++) {
		$s = new TabString();
		$s->copyFrom($strings[$i]);
		$track->addString($s);
	}

	// Copy Measure Header according to $measure_number
	$mh = new MeasureHeader();
	$mh->copyFrom($tab_source->getMeasureHeader($measure_number));
	$mh->setNumber(1);
	$tablature->addMeasureHeader($mh);

	// Copy Measure according to $measure_number
	$m = new Measure($mh);
	$m->copyFrom($tab_source->getTrack($track_number)->getMeasure($measure_number));
	$track->addMeasure($m);

	
	$render_output = $tablature->getRenderer('ascii')->render(0);
	while($render_output[0] == chr(13) || $render_output[0] == chr(10))
	{
		$render_output = ltrim($render_output, chr(10));
		$render_output = ltrim($render_output, chr(13));
	}

	$output = "Measure " . ($measure_number + 1);
	$output.= " (" . $mh->getTimeSignature()->getNumerator() . "/" . $mh->getTimeSignature()->getDenominator()->getValue() . "):";
	$output.= "\n";
	$output.= $render_output;

	return $output;
}

I"m sure there is a better/easier way to do that. But for the time being, this function works and could easily be extended to render a range of measures.

For future version, I suggest to add this feature to the renderer. :)

Best,

MrChros
