When I convert a MIDI to SSEQ, note slide effects like volume slides, pitch slides etc. seem to get lost in-game.
I think this is caused by one of the programs I use to convert MIDIs: Anvil Studio or midi2sseq.

I’ll show what I mean with those note slide effects using some examples.

Example 1: The high sound at the ‘NSMB Ghost House’ music contains pitch slides. If I convert the SSEQ to MIDI, and then convert the MIDI back to SSEQ using Anvil Studio and midi2sseq, the pitch slides disappear.

Example 2: The World 8 music also contains a pitch slide, used by the lava-ish instrument. If I convert the SSEQ to MIDI, and then convert the MIDI back to SSEQ using Anvil Studio and midi2sseq, the pitch slide disappears.

This is the way I convert MIDIs to SSEQ:
_Opening the MIDI in Anvil Studio
_Choose option 'Export MIDI-Format 0 file…' *
_Converting the MIDI to SSEQ using midi2sseq
_Replace 'BGM_X.sseq' with the SSEQ I just made in the sound_data map
_Make a SDAT file with NDS Editor (kiwi.ds)

*This could be the cause of the problem, but if choose the regular 'Export' option, midi2sseq.exe will crash if I try to convert the MIDI.

I hope there's someone who knows a solution for this.

The problem isn't caused by the SSEQ to MIDI conversion. If I download MIDIs from internet with note slides, also then the slides won't work in-game. So it has to be something in the MIDI to SSEQ conversion.

I've noticed that as well, as it seems when I test a midi with the in-game instruments(from a dls export of the instruments used by the sseq) in FL Studio, the notes do what they are supposed to do.

So.. No-one has a solution for this?

Since no-one at the board seems to have a solution for this..

Do you know someone, not from NSMBHD, who's very good with DS Music Hacking and may knows a solution?

I really want to be able to use those note slides in my music hacks
