"MV Ephex Rack" combo Vicanek effects

Postby k brown » Tue Jun 18, 2019 9:52 pm

Inspired by the 'effects stack' Martin included in Karplus-String IV, I combined MVerb 7B, Martin's Quad Chorus and my own very lonnnnng Time, nearly-infinite Feedback delay into a retro-style effects rack.

I added an adjustable 2-pole Butterworth high pass to the MVerb.

The Quad Chorus is great for stereo-izing mono-output synths.

The Delay has a max Time of a full 10 seconds for roughly approximating 'Frippertronics', so also includes a "Play over" button for playing notes over the repeating 'delay cloud' without adding to it. Turn it off, add more notes to the 'cloud', and so on. The feedback max is set for the maximum amount before 'run-away'. The line has subtle low pass filters in it to make each repeat very slightly duller, as would happen with the hardware tape recorder based "Fripper' system. One could probably get even closer to the repeated tape copy result by adding the right kind of distortion in the feedback line, but I haven't experimented with this yet.

Carrying the 'Frippertronics' analogy a little further, I should probably add the ability to toggle the "Play Over" button by MIDI Footswitch. Spogg - didn't you have that on Flooper? I imagine guitar players would like that.

UPDATED (in original post -I'm learning :roll: ) -

- Added ability to switch Delay to after the reverb (this was the signal flow of Eno's Discreet Music).

- Added "Play Over" control by MIDI Footswitch, with selector for CC# 64-69.

I'll probably do a second version of this with a multiband EQ in place of the Chorus; Eno's Discreet Music was: Synthi AKS playing simple sequence > graphic EQ > reverb > Dual tape-deck tape delay rig (~ 7sec. 'degenerating' near-infinitely repeating delay).

Yes indeed. That's exactly what many stompbox looper pedals do, so the Flooper can do it too.

Once again, your GUI looks FAB!

Thanks - can't take credit for the knobs though; I'd like to know who made 'em. They've been in my toolbox since long ago SM days - they didn't identify themselves. I did alter their appearance with transparent overlays to make them less glarey and contrasty.

Discreet Rack - Roughly approximates the kind of signal path used for Eno's Discreet Music.

- Simple 5-Band EQ. I think I recall reading somewhere that Eno used a cheap home HiFi-type graphic EQ for DM.

- Martin's MVerb 7B, with my addition of a HiPass filter in addition to the 'Tone' control (Damp).

- Looping Delay, up to 10 seconds long; Eno/Fripp usually used between 3 and 7 sec. Very small amount of Low Pass, High Pass and Distortion in Feedback loop. Delay can be placed before or after reverb. "Play Over" switch that can be activated by MIDI CC #64 to 69.

Chorus 69

Postby martinvicanek » Sun Jul 14, 2019 6:03 am

Thanks Kevin. I feel a little embarrassed with my name in the headline. :oops:

Anyway, I posted my latest chorus effect here, if you want to replace the older Quad Chorus.

Thanks again!

I'll do just that!

Just wondering if there might any sonic/musical utility to a chorus with a selectable number of voices. :ugeek:

Here's v1.01 with Chorus 69 in place of the Quad Chorus:
