Delays and reverbs both work really nicely in feedback patches (spring reverbs in particular). A compressor/limiter to help keep it going infinitely without clipping – although you could patch an inverse envelope follower in Maths and use that with a VCA to achieve similar results. A matrix mixer is nice to have too of course.

cold mac and a-138m are my faves for feedback, especially patching cold mac as a compressor but can be fun as a crossfader too (can do a lot of the kinks stuff too). If you’re trying to save space check out the AI synthesis matrix mixer, although I do like the space of the a-138m. I also like to use my W/ as a delay or looper—not sure if you mean loops as in MIDI looped sequences or externally recorded loops, but that could be fun, and since I’m basically just seconding what @Starthief said a bit of delay is always nice so something like that in pedal or module form (like the w/) could be worth considering.

i’m curious how are you using your w/ as a delay?

I keep forgetting Cold Mac can be a compressor! I’m making a note to try it this evening. :grin:

i think there might be more than one way to do this, but I usually have it in loop mode—loop length is delay time, offset voltage into that controls the repetitions (or feedback? I’m not sure what the technical term would be in delay terms, but its how many times you hear the loop before it decays away and is replaced by new material). The manual is very helpful, and the thread here is deep but with search can answer a lot of questions too :slight_smile:

thanks i’ll look into that!

I’m starting to think maybe the best pair would be an es-8. My output plans involve going into Max, but just for audio. It would be nice to actually do some modulation in Max as well. While the es8 ain’t cheap, it keeps on giving. For now, I’ve gotten Cold Max and the ResEQ, which will likely be a very fun and deep pair.

Start the tape and patch a -5 to +5v static source to that. Flick down on the toggle to set first cue, up on the toggle to set second cue. Looping will start automatically. Press record. The time between your down up is delay time. At 0v the delay will accumulate infinitely and clip the output eventually. Positive volts results in destructive looping, negative volts is slightly different, but sounds similar.

I’m not at my rack, but I think that’s it.

You gotta have a matrix mixer for feedback. The quad VCA mixers are good matches too—A135-1 or 135-2.

Sorry it took a bit longer, but I’ve built the module and used + tested it a bit. From my testing so far it seems to perform well, didn’t max everything out outside of the matrix mixer but I couldn’t hear any bleed or noise + it’s still easy to work with despite it’s relatively small size.
I’m very happy with it so far :slight_smile:

I ended up making room for the Doepfer one, but it’s good to hear that the AI Synthesis one is good as well.

is anyone here running contact mics through their system?

i’m making some contact mics for my drums and want to eventually bring them in through rip. i’ll probably run them through an external mixer first - will this boost the signal enough, combined with rip? will i need some more attenuation once it’s inside the system? whimsical mentions needing attenuation after accepting signal from pedals through rip, but i was wondering if a pre-rip boost via mixer would do the trick.

I’ve messed around with one. I have a Doepfer A-119, provides more than enough gain to use with Morphagene. In fact, the Morphagene itself actually has enough to gain to boost even the cheapo Radio Shack one if have.

i’m relatively new to contact mics - do loud sounds provide a hotter signal? do they work like that?

Yes, but its about force and proximity to the mic as well. Honestly, I’m no expert on the matter, I’d check out the thread here about contact mics, people know much more about it than I.

Some information to be gleened here:

I’d be leery of spiking my morphagene running a piezo straight in. Am I worrying too much?

To knowledge all that would happen is that you would overload the input and cause some distortion. I think the Morphagene is designed to take lower level (non-euro) inputs and amplifiy them. Plus I’m sure the internal levels happening with modular signals are much hotter than what a piezo would put out.

My concern is that piezos can spike very high voltages, much higher than normal modular levels. I don’t know if morph has sufficient protection.

Yeah that would be a question for the Morphagene thread or the Contact Mic thread directly.
I almost exclusively use a preamp first, Doepfer A-119, before the Morphagene. Never had any issues with that.
