Hej Reklamchef!
If it’s compatible with TG77 thats good news, difference between SY77 TG77 and SY99 should be device numbering in the syxex messages, midi implementation manual should tell the difference.
See the SY77 editor as an early release, there will be updates later on.
Bank and Library would be great to, I’m struggling to understand the feedback matrix and hopefully implement more function further on. I have been working so intense on this editor and SQ80 – D50 panels (available from downloads page) so it’s a break from CTRLR for me during summer.
If you want to edit SY panel you open /Panel/Layer editor and Click/Buttons layer (to hide “Buttons” layer), then you can edit with Panel mode Ctrl+E (CMD+E).
