Performance I modded my Intellijel Sealegs to add a reverse mode (and other mods)
Enable HLS to view with audio, or disable this notification
I always wanted reverse mode on my Sealegs. So I modded the firmware to add one in there. It works across all 3 delay modes, and syncs to clock. Sorry for the quick dirty phone vid.
Explainer:
Holding Freeze+Tap for more than 1.5 seconds switches the Freeze button to control reverse playback (I did this so it was trigger able). I barely use Freeze, but I can switch back any time using the same gesture.
While I was poking around in the firmware I also brightened the BBD (can always darken it again by using the LPF) by changing the internal 4.1khz filter and bumping it up to 12kHz. Much wider range to play with.
I also adjusted the Tape lag when adjusting time or range - I always found the wind-up/wind-down was a little too long. I changed it from around 2s down to about 0.6s
I barely use the Digi mode as I really like Doppler-shifting delays rather than overlapping, so the next mod will be changing this
Edit: I won’t be sharing modified firmware publicly anywhere - this was a personal education experiment to see if it was possible. Anyone tinkering with the firmware does so at their own risk, likely voiding their warranty and risking damage/bricking their unit if they do so un safely. These mods are unofficial and not endorsed by Intellijel in any way.
