It sounds like a saw synth sound. I couldn't find CS-80 among 1000 of voices on my MX49. Any ideas?
The instructions of the “Playing the Voices” section of the Owner’s Manual assumes that you are starting from the top display with the default settings immediately after turning this instrument on. If the instrument is in a different status, or for some reason you cannot return to the top display with the default settings, simultaneously hold down [SHIFT] and press [SELECT]. This is the Quick Reset function and allows you to return operation to the same top display as when the instrument is first turned on.
Reading the writing above the right front panel buttons, select “Brass” (button 7)
“BR:” appears as the Category
Use the [INC] button or the Data Dial to move through the Brass sounds
You can quickly move through the Brass sub categories using [SHIFT] + [BRASS]
This should leap frog you to the first sound in each of the following SubCategories:
001 - 019 are “Solo” brass
020 - 036 are “BrsEns” Ensemble brass
037 - 047 are “Orch” Orchestral brass
048 - 068 are “Synth” brass
The CS80 Type sounds will be found in the Synth Brass area...
