Midi Player

Postby MyCo » Sun Apr 28, 2013 3:50 am

Hi,

In the last couple of days, I've been working on a Midi/Sequencer-Library, and finally on a Midi player.
Midi Player3 (MyCo).fsm
(190.6 KiB) Downloaded 1856 times


This is a very early version of the Midi-Player. It is not very stable, because I discovered some weird FS bugs on my way, that I had to workaround. Hopefully Malc get them fixed.
The player is pretty basic, but the Library is made for future Midi-manipulations (for a sequencer). Right now it can only load Midi-Files, but a save function wouldn't be hard to implement.

I call this one a community project, that means that I hope there'll be some people that help me to improve this. If this doesn't happen, I'll keep future developments for myself :twisted:

omg basically!
I don't know if I can help MyCo,
u r more tech savvy than me.
If someone would implement save it would be astounding.
MyCo, if you would like my .fsm for DreamSequence Pianoroll,
I can pm it to you. I don't know if I want to make it open source.
Here are some of my Ruby mods with sequencers in mind->

Well it does work :) . Only had a brief look. A few midi files wouldn't read...
Code: Select all
Unsupported Event Type "0x00"["(eval):578:in `readEvents'",
"(eval):82:in `block in readFile'", "(eval):76:in `times'",
  "(eval):76:in `readFile'", "(eval):35:in `event'"]

But this happens a lot, with 2 different formats *Midi....*Rich Midi,...probably is that....

Looking forward to seeing where this ends up...the whole idea sounds great. :D

Not sure if i can help, but am there if needed.
can't wait to have a good look at it. Some sort of version of this will definitely appear in
a future X11 update, that's for certain.

I've though about implementing this before, but never actually tried it.
Now you've flung the door wide open, not much choice but to just walk in...... :D
Cheers.

Well, there is no chance to fix a non-working midi file problem without actually having the non-working midi file to test it.

RTMF Midis should AFAIK work, too. There are only new Meta-Events in this format, and the file reader should go over that in the "I don't care" mode.

The "unknown event type 0x00" Message indicates, that the previous event data wasn't read correctly.

Yeah!
very nice! we've all been, as former SM users, dreamin about this!
And Finally there it is... :D
Thanks MyCo 8-)
First idea that comes to my mind, would be to filter,isolate and recognize the drum track and send it to... a drum player :?

The file uses running status midi messages. I prepared that type in the Lib, but couldn't test it before. I fixed that.
New version is in the first post.

Hi myco

That is a great little creation you have there! is there any scope to have midi recording with this? that would be a great feature to have, such as in some piano synth/romplers allow left and right hand midi recording like Pianomissio, EZkeys etc

Thanks for the hard work! and for sharing! :)

This looks very promising indeed - thanks, MyCo.
I don't tend to use .mid files much - but this could change all that; it would be so cool to have a standard file type to use for this kind of thing, instead of us all inventing our own little proprietry formats.
All schematics/modules I post are free for all to use - but a credit is always polite!

Thanks. Yeh, all good.
Note:
i loaded I file with a 3 tracks on it, and listened to your system split it over the
3 channels....and it was then i realized the implications of this set-up. Huge. :shock: :shock:
