Kit to add CV / Gate / Filter sockets to the Roland TB-303

When used in conjunction with one of our MIDI to CV converters, such as the Pro-Solo mkII or Pro-2000 mkII, these three additional sockets will enable the synth to be played from a MIDI keyboard or MIDI sequencer.

The inputs are on 3.5mm mono jack sockets which provide the following control:
CV - provides Volt per Octave control over the oscillator frequency
Gate - controls when notes play (0 volts = note off / >3 volts = note on)
Filter - controls the cutoff frequency of the low pass filter (from aux out of converter)

The kit contains all necessary components and diagrams for connecting the wires / components, and mounting the three 3.5mm mono jack sockets.

Used with a Pro-Solo mkII or Pro-2000 mkII this kit will give you the following control over the synth from a suitable MIDI keyboard or sequencer:

Notes - at least 5 octaves range - (this is not limited by the kit or converter, but by the synth itself)
Pitchbend - range can be set in the converter
Modulation - from converter's inbuilt LFO. Speed and waveshape can be changed in real time.
Portamento (slide) - rate can be changed in real time.
Filter cutoff frequency - can be controlled using any continuous MIDI controller (cc) or other MIDI message such as Aftertouch or Velocity
Low / High / Recent note priority - can be set in the converter
Single / Multiple note trigger modes - can be set in the converter

See the specifications of the Pro-Solo mkII or Pro-2000 mkII for further features.

Please note that the five socket version of this kit works in a different way, and so this three Socket upgrade cannot be later be upgraded to the five socket version without replacing the entire kit.
