Korg PS-3300 - Keyboard and Foot Controllers

Keyboard and Foot Controllers

The Korg PS-3010 Polyphonic Keyboard is a specialised keyboard with its 48 keys (not 49) and proprietary 60-pin connector that connects to the Korg PS-3300 via a special cable, the Korg PS-3001. The keyboard has a trigger mode dial selector switch with 5 different trigger modes as well as a momentary switch for retriggering of envelopes during sustained notes, plus three on/off sliding switches. There is also an X-Y joystick with calibration sliders and separate CV outputs for X and Y direction movements, these can be connected to any of the many CV inputs of the three synthesizer units of the Korg PS-3300 for some advanced modulation control. In fact, if both CV outputs are patched to two of the individual Channel Amplitude CV inputs, it offers an early version of vector synthesis with different sounds fading in and out by moving the joystick.

The PS-3040 Dual Foot Controller is basically two CV control pedals with variable range, which also can be connected to any parameter with a CV input, adding greatly to the possibilities for expression. The voltage range is set with knobs on the PSU-3302 panel of the Korg PS-3300 and is part of the Voltage Control Processors. The pedals are made out of heavy duty cast metal and are designed to have the entire foot placed upon it giving the player the kind of precise control one has for example over an organ volume pedal. (Note! This set of pedals is in addition to the Sustain/Release pedal described earlier).

There was also a junction box called the Korg PS-3050, which was for controlling up to three Korg PS series synthesizers from one keyboard by routing a PS-3001 cable from the keyboard to the junction box and then routing separate cables from the junction box to the PS synthesizers. The only other functionality the PS-3050 junction box added was that octaves could be switched on and off selectively for the PS synthesizers, effectively enabling keyboard splits.
