Have read instructions and you can save only one setting for recall
When you have set the echo up as you want to save it.
1 press and hold foot switch and switch switch to T lock position
2 to recall that one preset , with power off switch to T lock and power on pedal to recall the saved preset.
If you are using it normally switch should be on normal or tails to use knobs to set delays up.
So if you use a preset from computer that you load , I wonder if you can after loading it, press and hold foot switch and put switch on T lock to save those settings ? Does not say as you say manual not great.
