MIDI in
The MIDI input of the SK2000 is used in two cases:
•
1. If you want to control the sound generation unit of the SK2000 from an external MIDI controller
•
2. If you want to merge the MIDI data generated by the SK2000 to the MIDI data of another MIDI device
The first case is the standard application of the SK2000 MIDI input. It enables you to control the parameters
of the SK2000 sound card from an external control device. You may select one of the SK2000 presets,
change the preset data or modify sound parameters in real time (e.g. filter frequency, reverb level, decay
time). Suitable controllers are the D O E P F E R
D O E P F E R Pocket Control, Drehbank, any XG editor or another suitable
MIDI control unit.
The second case is used if existing MIDI data from another MIDI device is to be merged with the SK2000
MIDI data. Typical applications are another MIDI keyboard or bass pedals. Note that the MIDI input of the
SK2000 is not suitable to process very high amounts of MIDI data (e.g. large SysEx strings from a software
sequencer with a lot of active tracks) but only single auxiliary equipment like keyboards, bass pedals or MIDI
controllers. Try to avoid intense MIDI data rates, otherwise data delay or data loss may occur. Problems with
the SK2000 velocity resolution may also reduce as the processor power is normally used to calculate the
keyboard velocity but has to process the incoming MIDI data too.
If both applications are not used the MIDI in socket is not connected.
Foot Controller
The most left connector is a jack socket for connecting a single or double foot switch. The two foot switches
have SUSTAIN (MIDI controller #64) and SOFT PEDAL function (MIDI controller #67). If a single foot switch
is used only the SUSTAIN function is available. A suitable double foot switch is e.g. the D O E P F E R
D O E P F E R VFP2.
Do not connect the footswitch unless the SK2000 is switched OFF. At power on the SK2000 electronics
checks the level of the foot switches and assumes that this level is the "off" state. So do not operate the foot
switches while turning power on. This feature allows the use of foot switches with contacts normally open
as well as those normally closed.
Please pay attention that in case you control external MIDI equipment from the SK2000 that some MIDI
devices do not support the MIDI controller #67 (Soft pedal). Sustain (#64) is recognized by nearly all
expanders, synthesizers and so on. Please refer to the user's guide of the MIDI device used if both
controllers are supported.
The double foot switch is not included with the SK2000 and has to be ordered separately if required. The
SK2000 will work without the double foot switch, although the functions SUSTAIN and SOFT PEDAL will not
be available to the user in that case.
Controls on the front panel
The SK2000 is equiped with the following controls on the front panel:
•
Two buttons labelled "Part 1, 2"
•
LED (as operation control and for display of menu mode)
•
Rotary potentiometer Headphone Volume (volume of the headphones)
•
¼ " stereo jack socket Headphone (for connecting stereo headphones)
In the menu mode the 88 keys of the keyboard are used as controls too.
