Trend price : 50-100€
This unit converts any monophonic signal like voice or guitar to Midi notes.
Overview
(weight: 1 kg) main panel features a 7-segments display, a gain peak-meter, 2 sliders and 4 membrane buttons.
Terminal connectors:
- audio signal input (impedance set: line or Mic)
-
Midi input and output
- impedance switch set
- Midi merge switch set (incoming Midi data are merged to out)
Voice
CP-40 converts monophonic audio signals from microphone or line-level input sources to Midi signal in (quite) real-time. The interface is really easy: just plug the instrument into the AUDIO input, then automatically the CP converts to Midi data to a module (or synth). The unit shows the tracked note on the display.
Midi
the tracking system outputs the following message:
- pitch note
- pitchbender value
- Control Change 11 (expression)
Control change #11 is the dynamic / amplitude of the signal.
Edit
edit mode features some special functions:
- gain : sets the incoming signal level
- Midi channel: sets the Midi ouput channel (1-16)
- octave shift: amount by which transmitted notes message will be transposed (range +/-2 octaves)
-
velocity expression: 5 modes to translate incoming amplitude to Midi velocity
- bend mode: how the CP translates the signal pitch fluctuation and how it will be transmitted to the pitch bend Midi signal
- threshold: determine the level in which the Midi note message will be generated (3 different preset threshold levels)
Latency
the tracking time is pretty long. According to different tests I made, there is about 10 ms of latency beween signal (using short attack and low threshold) and generated Midi datas.

Review
OK: rare / fun
NOT : slow tracking / not so precise / obsolete
"Funny machine for experimentation. As tracker it is slow and most of the time not so precise. I would not recommand CP40 but a very cheap price but since today there are a lot of better plugins even for free."
