eupmini cannot play Ultima Trilogy I ♦ II ♦ III soundtrack

[greg-kennedy]

The soundtrack for "Ultima Trilogy I ♦ II ♦ III" is in .EUP format with a common .FMB bank, but it does not play with eupmini. The file contains some track numbers of -1, which causes an assertion failure. Even if those are ignored, it plays for the correct amount of time, but the output is entirely silent.

I wonder if this is an older version of .eup format: none of these specify the bank name (has to be renamed to .FMB at least), and offset 0x7F6 says "EUPHONY" instead of "High-EUP". It seems like it is close to working but there is some confusion in instrument or track mapping that makes it produce no sound.

Here is the soundtrack in .zip file: ultima.zip

current implementation of eupmini is capable of playing .EUP files created for internal sound sources, which programs MIDI channel tied to FM type of sound engine (6 tracks), and MIDI channel tied to PCM type of sound engine (8 tracks), both of which match with specific hardware circuitry in Fujitsu FM-Towns computer. High-EUP editor/compiler firstly only generated such .EUP file, then High-EUP editor/compiler moved out of .EUP file format as a whole to a more standard MIDI format (.MIDI or .SMF), as far as I know.

For the moment I see two directions: 1. transform such .EUP file for external (MIDI) sound sources in a .MIDI file or a .SMF file and let the user play it with its instrument of choice, or 2. attach a standard internal sound font and play .EUP file created for external (MIDI) sound sources, though I think this is an hard job for me.

I will start by looking around and reading Featuring Paper: Musical Instrument Digital Interface Sequencer Software: EUPHONY
