The pitch change will now follow the voltage input.

Press the “CV” button on the front panel. To use CV mode, connect a voltage source between the Ground terminal (G) and the C.V. It is also unlikely to work with CV out from the average synth, and we definitely can’t answer questions about particular set ups – you’ll need to read the info here and do your own experiments… Virtually any waveshape will do, but it should be symmetrical such as a sine or square wave.Īn alternative method to vary the pitch externally is by using the Control Voltage mode. Note that CV is not suited to pitch-perfect applications but can be great for pedals. If you are not lucky enough to own one of the very rare HK940 keyboard controllers, you can still control the pitch change by applying a variable frequency with an amplitude of 5V peak to peak to the “KYBD” terminal at the rear of the H910 using the “G” terminal as the ground. Therefore playing a note will allow you to transpose the input audio by the number of semitones selected by the note. Each other note represents a pitch shift equal to that number of semitones away from the middle C.

The high C represents a pitch ratio of 2.0 representing a pitch shift of 1 octave up. The middle C represents a pitch ratio of 1.0 (unison). The low C represents a PITCH RATIO of 0.5 in other words, a pitch shift of 1 octave down. This is a two octave piano style keyboard. It is designed to work with the HK940 keyboard controller accessory. Keyboard Mode is selected by pressing the “KYBD” button on the front panel.

You can’t, except for the method detailed below, which is not suitable for most synths. Please don’t send us “can I connect my… keyboard/synth?” questions. IMPORTANT: we want to make it clear that “Keyboard” mode does not mean you can just plug in a synth/keyboard – that’s actually kind of a red herring as it only refers to the Eventide control keyboard which had a unique design.
