A Vocalist is a device with which several vocal voices can be generated.
There are individual hardware vocalists (vocoder) or into other devices (such as keyboards) integrated modules.
To use the vocalists, there are various types of control, for example, an arranged vocalist track (AVH - see ProV-Midifiles) or vocal harmonies (VH - see Pro-Midifiles). Both species are partly integrated in our files. If not, often the channel 5 can be used for control (see Midifiles).
