Hi Guys,

I believe that the Prophet 5 had VC Resonance but I profess I need to look
at the service manual again to see if that is correct.

The Oberheim SEM-1a did not have VC Resonance and I always found that this
was a mistake. Having Worked on so many products over the years, I usually
discovered that having a feature ultimately was better than having to work
without the feature. Modulation of Q or Resonance by various sources while
processing a signal produced another facet to the filter control.

Perhaps I should build a prototype system to further test and send some mp3
files of the results to see what you think.

Regards,

Terry
