Anyway for making a less sized generated vgm

Hi all,
i search a new way for making Sound for Sega Genesis with SGDK.
until now i used the TFM driver but it's need to write all the pattern manually and the tfe format isn't very documented for making a conversion tools.

So i have started to search a tools with can take a midi file at input and made a VGM File ( maybe a futur SGDK feature

)
I have find the nineko's mid2vgm 0.002 Beta
That's soft works great but the vgm seems to be very sized : 215Ko for 1min of midi.

Here is the result with the FF5 intro and mic_s vgm player :

Did you know a better way ?
Thanks

You need to use VGM optmization tools on the VGM to get the size down.

There is 233Kb of samples in that vgm file.
Not all the length of the samples are used so reductions could be made with the correct software. This file uses v1.61 dac streaming so I do not know whether there is any software available to optimize this yet.
The sample rate is 44100 so you could reduce that also.

hi,
thanks for the fastest reply,
i use vgm cmp pour try to reduce the size but i will earn just 2Ko

did you know a tools for reduce the vgm sample to 16Khz ?

I am currently writing a tool to solve your problem.
It should be complete very soon, it would have been done hours ago
But I had to go to bed.

I have written the optimizer, It reduced the file to 41KB.

Any chance of that being put under an open source license or at least recompiled for other platforms? Maybe perhaps even added to the tools with sgdk?
