'F0 52 00 6e 64 xx' commands #17

Open mungewell opened 3 years ago

mungewell commented 3 years ago

As @shooking discovered there is a command which will cycle through available effects and report via midi.

$ amidi -p hw:1,0,0 -S 'F0 52 00 6e 64 05 F7' -r temp.bin -t 1 ; hexdump -C temp.bin | head

This command is VERY sensitive to how it is run. it MUST be run whilst the pedal has a completely empty patch, if not the pedal will crash and/or reboot.

Interestingly the screen (yay fixed it) will show the graphic for each effect in turn on the 'slot 0' position, but under the parameters page it shows a solid bar across the area were we would see that parameter values. If the contents of the screen is scraped, it only reports a bypass effect.

$ amidi -p hw:1,0,0 -S 'F0 52 00 6e 64 02 00 01 00 F7' -r temp.bin -t 1 ; python3 decode_screens.py temp.bin

There are 2 more '0x64' commands which cause a response on MIDI.

So your Pedal LCD screen has come back to life??? Awesome news. Hoping you didnt just have contrast at 0 :-( You code is so neat (and beyond my Python skills) that I was having an Autist moment ... but the screens code looks so perfect? Ah the physical screen.

Notice one can use the delete effect to remove the effect, but the cycle carrys on from "last position". I was wondering IF I delete an FX from the pedal, does that crash the cycle. If I enable FX it still has the initial part in "bypass" mode - that's why I was hoping there is some IDs in the returned value - because if one can use this to get list of available FX on pedal then use your "write FX ID group ID to slot M" that might allow the patch to respond properly? I guess I should open another "issue" regarding what is the relationship between info coming from this probe v ZT2 content.

Glad to hear LCD is working.

actually it just need slot 1 to be empty. I revisited command again. I can have patch 56 with COMP on FX2, but FX1 blank. The iterator will make this 1st FX cycle thru available FX's on the pedal.

So it never seems to update the "Bypass" initial setting.

I revisited this topic. It should be run in PCMode!!! Then it appears ok

ok so it seems this 60 29 is used before. It seems to be some get iterator? then we send a start get next until we get back "end" signal

so 60 09 60 29 setup iterator get date 64 04 to start 64 05 in a loop until we get 64 07

Ie towards end looks like
