Hey psycle 1, check out Simeon's blocks here,
http://simeonharris.co.uk/Blocks/blocks.html.
These are compatible with Quantum and have full loading instructions. I'm not sure if older blocks will work or not.
From memory...! Roughly like this, though it's better to read Simeon's instructions in case I miss something!!
If you've installed Axe-Edit on PC, there should be a Fractal folder in your 'Documents' folder.
If you explore it you should locate a 'Blocks' folder.
Put on Axe-Edit, say you want to put in Pitch blocks, call the Pitch effect up in your preset.
On the bottom left of the screen, when you click on the Pitch block on Axe-Edit, at the blocks bit, click on the '+.'
It will want to save your Pitch block setting.
Save it, any setting will do...I call it something like Pitchhh, to remind me it's not a 'proper' block.
What that does is to create a 'Pitch' folder in the Block folder [in your 'Documents' folder], with a block called 'Pitchhh.' This is done to create the folder so you can then put blocks into it.
Switch off Axe-Edit.
Simply go the 'Pitch' folder and copy/paste Simeon's Pitch blocks into it.
Restart Axe-Edit, it will search the block library upon restart.
Then to access the blocks, simply select a pitch effect in your preset, click on the empty space on the bottom left beside the '+' and you should see a dropdown list of the various pitch blocks.
This works for any block, i.e. I would call up the delay effect in a preset and save it as 'Delayyy' for example to create a delay folder and so on.
Of course, if you invent any nice ones, you can save them yourself for later use.
