> ... Setting a value of '1' appears as '61' on screen for Ice-Delay Time parameter The parameter values sent with `Sysex:` are set relative to the defined __minimum__ value...

> ... where are you getting the [19, 581] range from? This is what's shown on the device screen. The "OnOff" section shows the mapped max value 562=0x0232

> ...I dont see any [581, 19]? @shooking ,this Time parameter range (rather `[19, 581]`) is for __SoftEcho__ (3S variant), not for IceDelay. You should be able to load it...

Nice work! Indeed, all of the A1 FOUR EQ effects are 1U, that is "wide" yet made for 1-screen units. These should be compatible with G1 FOUR and similar. G3n...

IIRIC, the paging also involves injection of Dummy effect (`fxid:0x01`) for the "third" page, this is in addition to the Dummy slot added explicitly for "wide" effects. Technically, it's possible...

There are 18 "wide" effects specific to A1 FOUR listed above. Generally, neither should be compatible with G3n/G5n/B3n. As for the "wide" effects from G1/B1 FOUR, there are already non-1U...

I mean "wide" as designed to occupy 2 slots (rather 2x4 parameter screens). These effects usually have 8 parameters. 1U models page these parameters; 3U and more models spread these...

I think of the highest byte of the Effect ID as category id. The 7th byte is used more like a mnemonic to further classify the effects: `0x80`:Bass, {`0xA0`, `0x40`):Acoustic....

- there are total 66 modules specific for A1 FOUR (see: https://github.com/mungewell/zoom-zt2/issues/58#issue-1580133203 ); - 28 of these are acoustic-guitar models (category id `0x14`), - the remaining 38 are spread over...

These are likely the settings for the on-device 3-par EQ, those 4 knobs: Lo/Mid/Hi/Vol. While different freq selection for the Lo/Mid/Hi between G and B models, these could be compensated...
