FURTHER ELEMENTS OF THE SD1
HARD DISK
The 6 GB hard disk supplied standard in each SD1 has been chosen to ensure rapidity and long life.
DISK DRIVE
Supplied standard, it is used to read and write 720 KB and 1.4 MB floppy disks in DOS format. Floppy disks formatted on any PC can also be used.
MODULATION WHEEL
This wheel is used to control the timbre modulation (generally created with the use of an LFO on the pitch or on the amplitude) but, with the
Rotor effect enabled, it can also control the Rotor speed variation from low to high.
PITCH BEND WHEEL
This is used to change the pitch to higher or lower on the timbre of the Right section.
AFTERTOUCH
Once a key has been pressed normally right down, a short section of the stroke of the key can be used, which can be felt by pressing further,
to control the addition of some effects such as Vibrato or Pitch bend. Thus it is simple to control the different timbre tones. The Aftertouch
version installed in the SD1 is the monphonic one, namely the effect produced is valid for all the keys pressed at that time.
VELOCITY
The key dynamics is used to control some timbre parameters such as the volume of the note or the filter.
GENERAL VOLUME
The volume cursor seen on the front panel controls the general volume of the audio outputs Left & Right of the whole keyboard, including the
microphone signals. The cursor does not send a Volume signal to the MIDI Out port.
