MIDI : Sacom SX-68 versus Roland SC-88 (sound issues)

[carlosemandrade]

Hello all,

I recently bought a SX-68 midi boart to use with my pro and have an old Roland SC-88.

I'm having strange issues with this module, previously set to "sc-55 map"

Sometimes games sounds amazing but sometimes the module changes "on its own" the instruments when i change music in sound test mode from some games (like Castlevania, Gradius II Gofer,..) OR during the game when it changes the music,  forcing me to "restart" or "turn on and off" the SC88 module, to play with correct instruments. 

Is there any fix for that ?
