No ZD2 modules in ACOUSTIC category

[nomadbyte]

There seem to be no ZD2 modules which reference ACOUSTIC category. Where does this category (and its id) originate from?

I figured that this came from the V6/V6-SP vocal processor's effect exploration done in issue #37.

However in ZD2 content the category seems to be named VOCAL (id = 0x1D = 29). In addition to that, some of the V6-specific effects appear to have a different category id taxonomy which conflicts with the one used with G Series.

IIRC this came from the FW of the AC-2 and AC-3 pedals.

Note: decode_effect.py does not work at present on these ZD2, it looks like they are missing some blocks compared to the other ZD2s.

Yep, if you want to decode them you can comment out the following...

Just as I mentioned in #37, it appears that the category-id: 0x1D = 29 is internally referenced in ZD2 modules as __BUILT_IN__. This applies at least to G-model, B-model, V-model (all of it's modules appear to have this reference).

In particular, with G-model and B-model the only modules in this category so far are the BDL modules: (G_OUT_EQ.BDL, B_OUT_EQ.BDL). These are not directly referenced in FLST_SEQ.ZT2, not sure if they are uploadable. Well, B1 FOUR actually has both of these but G1 FOUR has only the G file.

As for the AC-3, indeed, its ZD2 is somewhat different (missing parameter description sections PRMJ/PRME) but otherwise is very much similar. All of the AC-3 modules reference the category (0x1D = 29) as AG.EFX.
