It doesn’t make it clear but I’m assuming they mean consumer line level. Either way, unattenuated modular audio is going to hurt (ballpark figure voltage peaks for Eurorack can be up to 10x those of consumer line level). Which is why I haven’t gone there.

Attenuated modular isn’t a problem. I do that here at the mixer but for a more minimalist setup, a simple passive attenuator before the Onde would work just as well.

Thank you for this! I just saw this thread and immediately fell in love with the concept. The Onde is on my wish list now but it’ll be hard to justify financially for… a while (like in years not months). So I’m glad I can at least experiment with a similar concept on a low budget. Actually looking on Craigslist for cheap violins and acoustic guitars now.

Look at the diy transducer speakers videos. All kinds of things sound good. Surprisingly, hard foam sounds really good.

Ideally, how would one mic this to record both sound boards (front and rear)? Naively, I’m thinking two large-diaphragm condenser mics, like each one a couple of feet from each surface?

I say “naively” because I have never undertaken anything like this.

I’m no expert but I don’t think that would work well. It might sound interesting but it wouldn’t sound natural and I think you’d have all kinds of issues with phase cancellation.

It’s on my to-do list (once I’ve completely reorganised my studio space) but my plan is to experiment with both an X/Y and M/S mic configuration, placed side on to the Onde.

I was experimenting yesterday with a stereo feed into the Onde. Previously I’ve had it set up just on a mono, monitor mix feed. It was interesting. There isn’t any traditional sense of stereo placement but it does sound way more open and airy. And being able to steer the mix so that the lower end goes more to the rear than the front has a big impact on the overall sound.

So much to discover.

Wouldn’t it make sense to test it and decide? It’s like recording other kinds of acoustic instruments where there are certainly conventions that one can follow but ultimately different mic positions would result in different characteristics that works for certain context in music.

If I had one of these I would be interested to listen with my ears how the different parts sound upclose (for close miking) as well as how the room responds to it (for distant miking). I would also try to capture the aspects of it which I find most enjoyable in comparison to just pluging my synth straigth into a regular speaker.

For phase issues you can try to get the front and back mics equidistant (in relation to the Onde) and reverse the phase in post like you would when miking a snare drum from top and bottom for example. Phase issues will have to be confirmed in post of course but two mics won’t be as difficult to get into alignment.

I wouldn’t be too precious with how I record such a thing as the point of it seems be to introduce some artifacts and non-linearities into a signal that can easily become sterile otherwise.

yeah I’m trying to think of it more like a 1.1 system more than a stereo system but mines still in the shop. That doesn’t stop me from thinking about how I’ll use it when it gets back often though.
