Any cool synth related places in Tokyo anyone can recommend (not just shopping)? Definitely wanna look at the second hand stuff, gotta be cheaper than Australia. There's a good list of places to check out from one of the Korg designers but I'd love to know if anyone has first-hand experience.

Thank you fellow synthgoon, but to imply I wasn't going to also burn 10bux on records and vidya is borderline offensive! Got some great noise and skramz stuff in Shinjuku last time, and a massive chunk of my game collection was purchased in various Bookoffs.

someone tell me if I've hosed this up myself

I have a "komplete audio 1" USB audio interface thing. I really should have gotten the 2 but I didn't

so I had a galaxy brain idea to just get an ordinary audio to mic cable, and then wow I can play my circuit into 1 and bass station into 2. it worked extremely well
(coz the komplete 1 has two channels, 1 is mic 1 is audio input, where the komplete 2 has two inputs, both can be used for either)

until now... any audio going into the mic input is now incredibly quiet and if I crank up all the gains and volumes I can hear it but its still quite and very noisy.. but it does work on some level

have I fried part of the internals of my Komplete Audio 1?

It's possible you fried the mic input if you sent a line signal without a pad.

The good news is now you have an excuse to buy a proper audio interface, or a mixer to send into the line in.

Most audio interface have combo xlr/jack inputs but it looks like the komplete one doesn't and expects only mic signal in input 1.

Line signal is 1000 times stronger than mic so it's probably not a good idea to send a synth in that first input.

Mr. Dick would suspect the hell out of software before worrying if the interface is fried. There might be a line/mic flag that got switched, or, for example, reaper will automute tracks if the input level or signal chain gets to high.

Parts question, Synthcube is having another sale and I grabbed a Wangernumb. It needs a Vactrol optocoupler. I have modern IC optocouplers on hand and just about zero experience with older types like the Vactrol brand. I do have LEDs and photodiodes on hand to kludge a homemade one, but I'm keen to learn. I see a range of stock on eBay and the boutiques but without datasheets I'm not sure what to pick.

By proper do you mean to say the Komplete range is rubbish, or for example, get the Komplete Audio 2 which actually truly supports two lines?

Would someone recommend something else?

Thing that surprises me I guess is that it's 95% fried not 100% fried, SOME signal still gets thru

I think the thing that fried it is more like plugging and unplugging, rather than the signal from the Circuit itself, because it ran fine for ages.

It's not rubbish at all. It's just from what I quickly read about it says input 1 is meant for mic levels only. The Audio 2 version looks indeed better for you if you plan to send it 2 line signals. Or any audio interface with 2 line inputs. 2 lines inputs is always interesting, just for the ability to receive stereo signals, from a mixer for example.

That it worked for ages with line levels shows its good quality. Just it doesn't seems to be designed for that. I hope it's not fried but only you can confirm it.

Yes, and yes.

That said, it seems like they'll be able to add Devil Fish mods to stock TD-3s (similar to what they did for the first style/case design of TT-303s, and of course TB-303s originally), so if that becomes a fully-baked option, and depending on price point, I might go that route.

I'm outside the norm though in that I seem to be collecting weird 303 clones, despite not having the outright intention or plan to do so...

He also had a ....curious social media meltdown shortly prior. While you can't get components that haven't been touched by third world exploitation, there might be better people to pay the middle man fee to.

If that's what you plugged into it you probably indeed blew the mic preamp, since the signal from your Circuit is going to be several hundred times higher voltage than what a microphone puts out. So yeah,

rickiep00h posted:

Your input 1 is now dead. RIP input 1. Plenty of 2-channel interfaces at a similar price point that will give you more flexibility, and all the software you got with the Komplete should be interface-agnostic. That is, whatever hardware interface you get to replace this one should work with whatever software you have already, with only some minor tweaks in your audio interface settings.

And while a bunch of possible workarounds will probably come up from people, the main thing to remember is that mic inputs are for microphones, instrument inputs are for guitars, basses, and some older keyboards, and line level inputs are for most other equipment, including a boatload of synths and synth-adjacent things like grooveboxes. Yeah, it's a pain in the rear end, but it's better than frying a mic preamp.

Most audio interfaces have combo XLR/Jack inputs and can handle both type of signal (provided you don't use the cable pictured above to route the synth into the mic circuit)

Even the Komplete audio 2 does and was just a few bucks more than the 1



It's really a case of bad luck and learning from your mistakes I guess. But you really want to invest in a 2 line inputs anyway, so you can handle stereo from pedals/stereo synths for nice reverb/delay effects. It really makes a big difference in your productions

Yeah ableton handled it as two channels easily.

idk if it was a huge amount higher, that would imply that the gain would be basically off and the volume low on the circuit or I'd get mass distortion, but I generally run things like synths at half volume and set the gain to get about 80% in ableton, and I had to add gain on the Komplete audio to get there. Maybe my understanding of this is off, it's just that it worked flawlessly.. until it didn't.

I've created henious abortions of audio equipment before. lol currently, I have a 12v Class D subwoofer amp with a dual voice coil 12" sub running off a pc power supply as part of my audio system.

Lol with this power supply I learned that if it draws too much current on the 12v rails (which I soldered all together) without any on the 5v rail it'll shut off the power supply, so I have a large resistor across the 5v to keep the whole thing running and supply 12 volts of delicious PC power supply to this very large car amp. I'll see if I can put up some photos. but regardless, this mic input thing is the first time I've really hosed something. take huge risks I say. gently caress everything

Yeah most (all?) DIs have a transformer in them that effectively "breaks" the continuity of the signal path, at least as far phantom voltage is concerned, so it'll protect against it for any gear that may not have a transformer in its output stage. It's probably not strictly necessary for a lot of modern keyboards/synths since a lot of manufacturers have some sort of protection circuit to prevent against exactly that situation, but there's really know way of knowing most of the time without digging into the schematics, so it's good to play it safe.

DIs do also match impedance (less important for modern mixers, but still useful) and usually also adapt from an unbalanced signal to a balanced signal. They're useful things to have all around if you're ever plugging your gear into a system you don't know/trust (or operated by an engineer you don't know/trust)

what does balances refer to in? like DC offset?

I still struggle to get my head around impedence and the implications

for example that amp I posted before can run down to 2 ohms I believe, requiring the two voice coils to be wired in parallel

I get that impedence is the AC equivalent of resistance (or similar) but I don’t get why some speakers have real high impedences. not that i’m asking for help on this regard just thinking out loud about my inadequacies
