Quite right, I should have listened to Adam who suggested another normalization in the past. Now fixed in this post.

Not necessarily, everybody can experiment and add features as you and others have done.

What I really meant was that anything much further than what I've already done, I haven't been able to make work - I'm sure someone else could (I've mentioned before that I've had almost no experience with packed/unpacked mono streams) I figured more extensive mods you might want to do yourself - I shouldn't assume.

Thank you Martin for Tilt filter normalization.

What I'm getting with this new Spectral Tilt is the volume now increasing when moved off midpoint - can we split the difference to maintain constant level? The new one sends the synth into clipping very readily.

I replaced the Randy schematic in the earlier post with Randy v1.01, which is the most recent Randy update with the Noise Envelope added - Martin had put it in an earlier version. I also added a button to bypass the Noise Envelope and another to bypass the Noise Comb Filter. I can't figure out how to do a Noise bypass of the main ZDF filters - someone else will have to help with that.

Also replaced the last Randy +_k2 schematic with one that also has the Noise EG and Comb Filter bypasses, plus LFO 2 can now be Bipolar or Unipolar.

Minor GUI changes to Randy v1.01 and Randy +_k2; schematics replaced in their respective posts.

Moved Spectral Tilt control to the Filter section to better reflect it's position in the signal path (after the Filter). This left room in the Osc section for a scope, which has no real utility in this synth, but they make me smile.

Thanks for the update, Kevin!

Martin has supplied a second revision of the Spectral Tilt Filter, so that's been put in their respective earlier posts (now named Randy v1.02 and Randy + k3.

Shouldn't affect Trogg's presets for Randy +, except for the output levels on some changing a bit.
