I have the following news:
PCB is localized in the RBSC group.
A new version of the board has been developed, in which bugs have been fixed.
A convenient case made of translucent plastic has been developed:

Changed the display order of bars: high frequencies are now on the right.
New colors are now used, such as: red, red and green, blue and red (all discrete).
New video:

A modification for ZX Spectrum has also been implemented:

A small series of boards has been ordered, I really hope that I can send it to everyone.
Unfortunately, time is short, but I will try to keep you informed.

ps: My many try case:

Is your project based on the vizualiser by Yeongman Seo?

"Is your project based on the vizualiser by Yeongman Seo?"
no, my project very-very simple for PSG (see photo, in MSX-EQ only one IC PLD EPM7128)

ps: As far as I can see, the project at the link for the OPL (?)

PAC-V (as it is called) can be used for OPLL, PSG and even SSC (through a modified vgmplay), you can see here. It uses 1 music channels as source for 1 bar and as such is quite different.

It would be nice if MSX-EQ could support OPLL as well.

I cant understand how PAC visualize PSG? For Example sound from game VK:

video time code:

and msx-eq video time code:

"It would be nice if MSX-EQ could support OPLL as well."
sorry, msx-eq can only PSG or, possibly, OPLL, as PLD is very simple... I could hardly place the spectrum visualization logic PSG...

ps:
I am waiting for a new version of the boards without errors, check it and hope to publish good news for those who would like to build such a cartridge for themselves.
