User instrument
You can modify the parameters of the SC-8850 sound to your taste, and save your new settings in Variation numbers 64 or 65 of the SC-8850 map/SC-88Pro map/SC-88 map (p.67). A sound saved
in this way is called a User Instrument. You can save 256 different sounds in this way.
The parameters you can set are Vibrato, Filter and Envelope.
The other sound parameters will use the values specified for the Part (Part parameters, p.65). Each Part has Part parameters which are named identically to the User parameters listed above which
can be set for each sound. This means that the parameter value that actually applies to the sound will be a combination of these two settings. For example, if the Vibrato Rate has been set to +20 as
a Part parameter, and to -5 as a User instrument parameter, the Vibrato Rate of the resulting sound will be 20 - 5 = +15

User Drum Set
You can modify drum instrument parameters to your liking, and save this data as a Drum Set. A Drum Set saved in this way is called a User Drum Set. You can save up to two Drum Sets, and
since each set contains 128 instrumental sounds, this provides a total of 256 instrumental sounds (Drum Instruments). You can also give each User Drum Set a name of your choice. User Drum
Sets are stored in Drum Set numbers 65 and 66 of the SC-8850/ SC-88Pro/ SC-88 map.
