  • The Akai Professional DecaBuddy VST Plug-in is a software equivalent of the HV10 Harmony Processor.

    It is capable of taking a monophonic audio signal and generating up to four harmony voices plus a unison voice that can track the audio input, and a Dual function allows doubling of each voice, providing a total of 10-voice harmonies.

    The various controls allow you affect the tone of the harmony voices. RANDOM introduces a random delay in each of the voices whilst FORMANT allows you to 'gender bend' the harmony making it more feminine or masculine. For really precise harmonies, the pitch of harmony voices can be quantized and each voice may be panned and mixed.

    Harmonies can be pre-programmed using preset or user scales, or they can be 'played' via MIDI.

    The DecaBuddy VST Plug-in allows you to add natural multi-part harmonies to your vocal performance, with real-time MIDI control.

    • Multi-part harmonies with up to 10 voices
    • Natural sounding harmonies in any scale and key
    • Formant control changes the gender of each harmony
    • Random delay recreates the natural timing discrepancies you would expect to hear from different singers
    • The pitch correct function can 'quantize' the pitch of each harmony and/or the original vocal in real-time

    • Does the HV1/HV10 work only on vocals?

      No. Those harmony processors can be used on any monophonic source, such as a saxophone, to create original ensemble effects. However, they cannot be used with polyphonic sources.

    • How does the HV10 use its MIDI input?

      MIDI can be used to select harmony presets via Program change of control harmonies in real-time via MIDI Notes.

      The HV10 has different programmable modes for real-time MIDI notes control:

      • MODAL:

        This is the first MIDI-controlled harmony mode and will generate an appropriate chord based on the major scale

      • FLEXICHORD:

        This is another intelligent MIDI-controlled harmonizing method which is very easy to use. It can recognize 3-part and 4-part harmonies played in arbitrary inversion on the keyboard and generate an appropriate chord with three selectable voices. This mode is most useful for keyboardists, as they can play the chords as they usually would

      The remaining MIDI-controlled modes can be used to play exactly the notes that are played on the MIDI keyboard or sequencer:

      • MONO CHN:

        This mode is most useful with pre-recorded MIDI sequences as in this mode each voice receives Note On/Off messages on a separate MIDI channel

      • WAIT ALL mode:

        This mode is most useful to play a fixed-part harmony accompaniment. The algorithm waits until the number of pressed keys is equal to the number of active voices (i.e. voices that are not turned off), and then assigns the pitches to the voices in lowest-first order

      • PRIORITY mode:

        This mode differs from WAIT ALL in that you can play as many voices as you like and the voices are assigned in a selectable priority order. This ensures that if a single key is played, it will be always assigned to the same (e.g., bass) voice, the second always to the second, etc

    • What parameters does the HV1/HV10 use to modify the harmonies?

      There are three main alteration parameters for each generated harmony:

      • Formant/Character:

        The character of each harmony part can be changed using this parameter. Male voices can be transformed to female voices and vice versa. This can be set individually for each part

      • Random Delay:

        The delay parameter allows you to introduce random delays for each harmony part to create a more natural 'ensemble' effect where none of the singers will actually sing exactly in time

      • Pitch Correct/Quantize:

        The pitch correct function allows you to 'quantize' not only the harmony parts for accurate pitch but you can also use the pitch correct feature on the original vocal part thus allowing real-time pitch correction
