and directly play your analog modular synthesizer.

Ideal for retrofitting vintage keyboards for MIDI control.

The kit includes a pre-programmed PIC microprocessor SOIC.

Connections

1. You can connect a DIN keyboard using the TRS jack. You will need a MIDI/TRS Type A cable or a MIDI/TRS Type B cable depending on how you have configured the jumpers in the MIDI-CV1.
2. You can connect a USB keyboard. The device will operate as a USB host and power the keyboard on its USB bus while receiving MIDI data from the keyboard.
3. You can connect the Midi-CV-1 as a USB device using a computer or other host connected to the Midi-CV-1's USB-B type socket. This connection will be used for connecting your DAW, such as Ableton Live, to the MIDI-CV-1.

If you are a composer, create your own MIDI sequences, backing tracks or songs using your favorite MIDI-USB keyboard.

The module uses a PIC 24 bit microprocessor to convert the midi messages from the keyboard or PC into digital codes which are then converted into gate and control voltages. These are buffered with precision op amps providing precise tracking over three octaves and to within 0.01V over 5 octaves.

The following MIDI-USB Keyboards are supported, others may work also.

• Arturia MiniLab MKII
• Arturia MiniBrute
• MidiPlus AKM 320
• M-Audio Keystation 49
• M-Audio Keystation 61
• WORLDE Panda MINI 25-Key Ultra-Portable USB MIDI Keyboard
