Shruthi-1 with SMR-4, low level sound with noise


Hi all
The unit long time not used, befor that its work well.
And now sound on really low level, like amp is not working.
Any advices what i need to check on boards and menus?

Many thanks!


Perhaps try the first and easiest - did you send it a midi channel volume command 0x07? Try sending it a value of 127.

Failing that, send it the factory data


it’s not worked.
Signal is on low level again.
