WIGGLING 'LITE' IN GUEST MODE

[tuj]

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?

Ah, makes sense.

Do you have anything plugged into the 1V/Oct of the HD?

[tuj]

[mt3]

Does drift happen without Rene plugged into the HD?

[tuj]

No, with nothing plugged into the 1v/oct input, the pitch stays steady.

The rene when sequencing other oscillators is fine.

[mt3]

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

[mt3]

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.

[mt3]

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

Sounds like the trimmer needs to be replaced. Email support@industrialmusicelectronics.com if you want us to take a look at it (email works now)

Dsmn, I was close.

did some more testing. Both the modulator and the primary are drifting without anything plugged into them.

Will email for support. Thanks!
