Introduction; Front Panel - KETRON SD4 Manuel D'instruction

INTRODUCTION

Congratulations for having purchased the new Ketron sound module sd4. This instrument
will enable you to play live with a wide range of sounds and to playback your Midifiles with
excellent acoustics. Thanks to the two mIdI In ports and to the built-in USB connection, sd4
is easily connected to any MIDI device (Master Keyboard, Midi Accordions, MIDI guitars etc.),
or it can be connected directly to any personal computer that has USB connections. The 32
sound parts inside the instrument can be used in various ways. For example, you can play
two midifiles simultaneously or play one of the many sound presets of the instrument from
an independent master keyboard while playing a midifile in the other MIDI port available.
sd4 offers 64 presets set by the manufacturer and another 64 that can be completely
programmed by the user. Each sound preset may comprise a maximum of three different
voices and the availability of numerous edit and control parameters.
