FWIW, the few links that do work, and show as a button, have targets like this:
ctrlr.org/?ddownload=6185
The rest are like this:
href=”/panels_deprecated?get&idx=50″
– but all any of those does is reload the deprecated panels page.
I managed to find a couple more downloads by trying different parameters for ddownload=, but they’re not consecutive, and two of them are five digit numbers, so that would take a while.
So, more downloads are in there, somewhere, but presumably only an admin, or someone extremely persistent, could ever get to them.
I found MFB-Synth-Lite-II.bpanelz and Roland-JX8P.bpanelz, by trying different numbers, so I’ve attached those.
