TX802 performances #7

probonopd commented 11 months ago

Would it be possible to also convert TX802 performances? Along these lines:

        wget -q "http://hsjp.eu/downloads/Dexed/Dexed_cart_1.0.zip"
        unzip -q Dexed_cart_1.0.zip
        bin/Linux/MDX_PerfConv --info -a "./Dexed_cart_1.0/Original Yamaha/TX802/TX802BankA1.SYX" -b "./Dexed_cart_1.0/Original Yamaha/TX802/TX802BankB1.SYX" -p "./Dexed_cart_1.0/Original Yamaha/TX802/TX802_Factory_Performances.syx"
        bin/Linux/MDX_PerfConv -c -n 65 -a "./Dexed_cart_1.0/Original Yamaha/TX802/TX802BankA1.SYX" -b "./Dexed_cart_1.0/Original Yamaha/TX802/TX802BankB1.SYX" -p "./Dexed_cart_1.0/Original Yamaha/TX802/TX802_Factory_Performances.syx"
        # wget "https://github.com/asb2m10/dexed/files/5360597/tx802bankb-fixed.zip"
        # unzip tx802bankb-fixed.zip
        # ...

TX802 Performance file SysEx format is ... an abomination. Even the guys at SysQuest (MidiQuest) have the same meaning...

It is a biiig ASCII file. It needs to be converted to a binary (undocumented) and see if it is anything alike to the known formats. Theoretically, it should contain VMEM, AMEM and its own PMEM.

Uh. Oh. Looks like that format is still a "frontier" for the open source world. Not super urgent, but maybe one day...

I am almost finished with it, but I can't find all the factory patches that are used in the performance file that I've found. TX802_Factory_Performances.syx from the internet has references to 4 voice bank files. I have the first two (= Bank A, voices 1-64). The problem is the Bank B, because all the downloads I've found are in VMEM format (4104 bytes), and not VMEM+AMEM (5239 bytes). Can anyone help?

BobanSpasic commented 11 months ago

Conversion added, but I can't find some good test files. The voice banks are the same as DX7II, just the performance file an addition. The voice banks alone are not suitable for testing.

Thank you very much @BobanSpasic. So far I have not found better test files yet.
