DOS NETWORKED LIVECASTING SYNTH v0.04 ohgodohgod please don’t crash when I’m not home edition

What is this?

Upload a midi file, hit play on the control. It will be rendered on a 486 DX2 66 Pentium 233 running dos with a true hardware Roland SC-55. Be a bit patient. It's an old computer.

Tech Jargon

A lot of music from the early 90s was written to be synthed on the Roland SC-55 and it's various cousins. Emulation of the device via soundfonts has not come close in all areas. Upload a midi and it will be synthed on real hardware and hopefully play over shoutcast. I have a (really bad computer) system running a TCP/IP stack in dos via packet driver, along with said Roland synth. For the heck of it I wrote a series of batch\qbasic scripts and chained curl + dosmid + some php scripts together. The result is that this here 22 year old machine will synth MIDI files you upload, and they will be streamed over an Icecast server automatically in the order they are queued. It probably is horribly dangerous to put such an old machine on the internet, a backup is in place as this is probably going to be wildly unstable and prone to issues. It probably will not be up all the time, I want to get back to playing Zeliard. ;)

Known Issues

  • SAPI player has a limit of 64kb filesize

Changes

  • 12/24/16 - Whoops. Icecast was not listening on IPv6, some picky devices may not have had working audio....I don't know what I should do with this site
  • 4/10/17 - Err, someone did a denial of service attack on the site, cleaned up a bit...why foot why
  • 10/12/17 - Bugs galore. Captcha in some cases was not working right.
  • 10/23/17 - The dos machine is now under control of KERMIT. Not really sure if this will be reliable...very broken right now, sorry....cannot resume work till tomorrow
  • 10/24/17 - SAPI, SB, and MPU401 SC55 functionality restored. May still be unstable. Goal is to re-add features, stabilize, then add OGG or OPUS midi recordings.
  • 10/29/17 - Switched to OPUS + OGG encoding for audio. If anyone has trouble with this please send me a tweet.

Has nothing to say about this file!

So I'm the original asker of this qseituon As an interesting followup, I also contacted Bruno Degazio who's the author of VL70m Librarian, a fairly recent VL70m tool for the Mac (OSX). He did not have any specific guidance for file formats, but he generously shared with me the source for his tool. The downside (for me) is that (a) it's Mac and I've never programmed Mac (though I have some good resources to turn to here) and more seriously (b) it's programmed in Forth which is a pretty obscure programming language. I'm still working my way through the code looking for the file I/O routines to see if I can get some insight into the binary formats, but it's slow going right now. My hope is to locate the specific structures/routines for file I/O and then port them to a different language (C++ or C#).But if anyone has thoughts/ideas about other approaches, I'd appreciate it.
