Hello kraftybob,
Thanks a lot for your reply. Sorry I didn't follow suit earlier but I'm new to this forum and I thought I would get an e-mail notification in case of reply (now I have checked the box).
1. Thanks for the character trick. Indeed a little tiresome, but at least it works. The best would definitely be if it was possible to edit the presets from a computer via USB connection.
2. As for the expression pedal problem, it's definitely not from the expression pedal, as it's obvious on the M5 screen that the software on the pedal sets the minimum as something else than the minimal setting. And in fact, for one of the settings I can't get where I want, I actually succeeded once, but I can't get it there anymore. It's a pity because the settings are not always extreme (e.g. feedback on delay effects) so if you want to get the effects a little crazy, you really need to get to that maximum. I hope someone has the solution to this problem...
3. As for the autosave mode, I've tried this before but it only worked once you are in a preset (I don't have a M9/M13 so I don't have scenes, but I think scenes are also some kind of preset). What I would like is to change the default setting of an effect, outside of preset mode.
Thanks in advance to anyone who can provide help
Regards,
Jean
