since this is a decompilation project, i will take a wild guess that it's now possible to modify it, isn't it possible to expand available settings? (bigger polyphony, bit depth, bigger sample rate, etc.)

That is not accurate. On the GZ-70SP (even emulated on MAME) the waveform is correctly Sine. There needs to be a new version that uses the correct waveform.

Do you take requests(perhaps paid) for decompiling midi synths?

What is workflow for creating conv2dll.c for our casio synth?
I see a lot of manual patching. Scary!

It would be nice to have step-by-step RE/patching process, to learn to apply on other VxDs.

outstanding reversing work, and what a clever idea to manipulate the binary headers. do you think the vxd -> dll conversion procedure could be repeated for another win95-era vxd softsynth, or did the sw10 have something special which made that possible? ghidra seems to have a vxd loader but haven't tried that out yet.

hi, i appreciate your work at making this synth usable in modern systems, but i found a problem with the MIDI, the one that is pre-packaged in Windows, no less, when rendering onestop.mid with sw10_pcmconvert then the output file sounds normal at first, but then at around 01:27 a hanging note kicks in, and lasts until the end of the song, not even fading out in the ending like other instruments do, i even recompiled it with MINGW to make sure that it's not a compilation error

(the output file)

Firstly, well done and thanks for getting the decompilation working. Can confirm the output is functioning when pairing with the original SW-10 ROM with sw10_pcmtools.

Just opening an issue here to track a need for a 'compiled' version of a compatible Windows MIDI driver build of this. Can be done with MinGW. (Same for WebMIDI if one wants to use in a browser setting hahaha). I have done both of this before myself in the past for different softsynths. This may come in the form of a future pull request.
