Hertz Donut MK1 - pitch drift |
br>tuj |
br>Hi:
I have a Hertz Donut mkI and the pitch will drift from time to time fairly substantially, like a 5th or an octave or more. Then it will eventually drift back to normal.
Any ideas? br> br> |

Is this while scanning through waveforms?
Or a static waveform? br> br> |

I was confused and thinking of the wrong module name. The problem is happening with my Hertz Donut. br> br> |

br>Ah, makes sense.
Do you have anything plugged into the 1V/Oct of the HD? br> br> |

Yes, Rene. It will follow the sequence correctly for a while, then glissando slowly up to a higher pitch, stay there for a while, and then glissando back down to C where I have it tuned. br> br> |

br>No, with nothing plugged into the 1v/oct input, the pitch stays steady.
The rene when sequencing other oscillators is fine. br> br> |

br>What happens when you plug the HD's Modulator into the 1V/Octave?
Also does the Modulator oscillator also drift? br> br> |

br>Part of my guess is the Modulator is affecting Primary at a frequency just above 0 Hz, where the modulation bus is also non-zero.
What happens when you assign 0V to the Modulation bus CV while doing your thing with the Rene. br> br> |

br>And pretty sure the Modulator never reaches 0 Hz, by design. br> br> |

br>Dsmn, I was close. br> br> |

br>did some more testing. Both the modulator and the primary are drifting without anything plugged into them.
Will email for support. Thanks! br> br> |
