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.

Personally really like using contact mics. I have two permanently installed in one case, and a few floating for other uses.
In the case I have one attached to the inside of a side wall, and one I mounted in a 4hp panel I made for it. Both run through a folktek amp.

Otherwise I’ll use fieldkit inputs or straight into phonogene.

Try to stay aware of levels Mainly for out of control feedback stuff, should at some time get a limiter or something like that, but it’s not a dier necessity.

I wanted to mount one in my case too.
I saw a video of Jan Jenilek playing his modular and you could tell he had one mounted in his, he kept tapping and shaking it. Its was really neat.

Yah it’s pretty fun.
One I have to kind of amplify the sound the whole case makes, touching wires and buttons and things of that nature. A bit of organic feeling sound to things, makes the case feel more like a cohesive instrument.

One I use as a trigger to feed into maths that than opens a lpg.
A trick I learned first from watching meng qi.

thanks for all of this! i’m so glad a community like lines exists.

could i get some feedback on a preliminary 84 hp build i’m dreaming up? open to all commentary on what i might be missing, what might be unnecessary, etc…

the idea here would be to bring in contact mics from my drums through the left rip, take copies of the signal and mangle/sample/etc them with the 4ms sampler and delay. jf could be used to generate sound or to further control the 4ms modules. crow and ansible provide norns and grid control, respectively. audio then gets mixed and exits through the right rip.

my hope would be that this system would be flexible - i’m big on improvisation, this would be for a solo drums and electronics set… it would be cool to be able to range all the way from ambient jan jelinek-type things to noisey dense collages to live dubby cyclic beat music.

any thoughts about any of this?

Bringing contact mics in through RIP might bear some more thinking about, I don’t know that it wouldn’t work but my “factory” RIP isn’t the most powerful at bringing stuff into Euro and my understanding of contact mics is that they need an especially high boost to get to Euro level (I see there’s already been some discussion of this above). If you’re going to build two anyways you could see how it goes I suppose, but I reckon you might want something else for an input. Depending on your use it also seems like you might want something like Mutable Ears (and there’s other similar options I think) that has an envelope follower.

Don’t have experience with DLD or STS but they seem very powerful and with ansible or crow sequencing you could probably do a lot of very interesting things!

i’d run the mics through a small mixer first, hoping to get some boost there - that meng qi split should (hopefully?) provide some boost too. could the mixer be enough?

i’d want to have like four mics around my drums and mix them into one signal (at this current setup) or ideally a stereo signal eventually. i’ll take a look at ears!

Does anyone know about this Vortex Generator module?

https://www.ebay.es/itm/Vortex-Generator-a-Maths-Benjolin-Fusion-Eurorack-10-HP-Function-Make-Noise/202873911784?

There’s a thread on MW about it
Looks interesting!

Has anyone here had experience slimming down from a large-ish system to a medium-ish system? Were you happy with the results?

I’ve grown to about 20u (18u + two 1u rows) and am considering slimming down to something in the 9u - 12u range, partially because of financial reasons (my Dad is having health/money problems and I could use some additional cash to deal with the immediate issues) but also I feel it’s gotten a little disjointed. However, there’s not a singe module that I own that I dislike and I’m pretty well balanced in terms of voices, modulation, VCA’s, utilities, etc.

For people who slimmed down their system - what strategies did you use?

In case anyone’s interested - here’s a link to my modulargrid. I’m not necessarily looking for specific feedback like “get rid of this and add this” but I thought it might be useful to see where the system is currently.

When I slimmed down my goal was to go from a collection of modules that I thought were neat to a designed instrument. Something that felt more cohesive. Framing it that way helped the decision process.
