  So for a pure focus on minimizing player time, this looks pretty optimal. For practical use in e.g. a 64k intro, I think a more compression friendly data format with a slightly slower player would be a better tradeoff in most cases.

  
  
  Thanks! You get exactly what I wanted for LSP "fastest" player: a reasonable .lsmusic file size but no compromise for speed.
  
  And yes, making the player slightly slower there is tons of better format for compression. At first I wanted a single data format, to avoid having different files for the same music ( like a "speed" format and a "compressible" format).
  But now I've worked on my 4KiB "SoftWired" compo, that is using LSP, I'lll definitively release a "-micro" option soon, with a different data format. Suitable for 4KiB. ( Anyway LSP is already used in two Oldskool 4KiB production this year :) )

• to me best PC 64kib this year. The rendering is so clean. And you can't go wrong when you wake up our nostalgia with a tape! :)

  Question: Would it be then possible to rip such a music file(s) from the production (i.e. disk, or memory) and write it back in a MOD musicformat? Or once converted, the MOD is "lost"?

  
  
  In theory this is doable as LSP is a conservative format ( ie LSP or MOD should sound exactly the same ). But in practice it could be quite challenging to write the LSP to MOD converter ( you have to "guess" any mod fx to reproduce the exact stream of volumes and periods ).
  
  Quite challenging, but doable. ( also keep in mind that such a reversed-mod will be totally obfuscated with plenty of weird fx commands )

  I've found a flaw with the player which might make some tunes sound wrong, though. Rather than trying to explain, here's a test mod which illustrates the problem:

  
  
  thanks for repro module. I fixed the issue. LSP v1.01 updated on github

  The benchmark seems to use VBI tempo. P6112 can perform well for such modules. Were you able to set optimal mode/settings/usecode for P6112, so that it sets DMAoff without Copper instructions?

  
  
  I'm not p61 expert I'm using baseline p6112. If you know how to finetune p6112 to get some cycles, please do a proper p6112 benchmark.

  Just so you measure correctly. The screenshot is misleading.

  
  
  No, LSP benchmarks are measured 100% correctly. LSP insane mode is taking half a scanline on average, including everything.

  P61 version should be specified.

  
  
  benchmark.adf is using "P6112-Play.i"
