Evolver Feedback & Grunge

[Arddhu]

Sorry if this has been covered already but I could nay find it.

Is it possible to use the feedback and grunge controls pre-filter on the Evolver?

I know this is possible on the Mopho but wasn't so sure about the Evolver line.

The grunge parameter effects the (digital) tuned feedback and delay feedback loops, which are permanently post-filter, post-VCA. The Distortion and HPF can both be moved pre-filter if required.

The Mopho doesn't have a 'grunge' parameter per se, it's just got a fixed feedback path with gain that goes post-VCA through a normalled connection to the external input, which is pre-filter.

Feedback on the Mopho/Tetra and Evolvers sounds quite different to one another.

Aha, that makes sense.

Cheers!

Oh forgot to mention an Evolver trick I came up with; if you want a feedback path which goes pre-filter you can use delay line 2 with feedback and time both set to 0. The amount controls feedback amount to the filter input. Play around with time amounts below 40 or so to tune the feedback to different frequencies, and play with the mix of amount and feedback to get tonal variations.
