Still working on that HS-60. Deoxit cleared up the scratchy volume pot and the H-M-L audio switch that was causing the audio to intermittently cut out, so that's good! Still no luck on the 4 dead keys, though. I pulled up the rubber strips and cleaned out any dust I saw, but that didn't clear it up. (I was told on another forum that I should try applying a few thin coats of graphite lacquer to the contact points under the rubber strips, so I'll try that when I get my hands on the right kind of graphite.)

Next I took all the keys off to try to trace the lines on the boards to see if there were any breaks that could be causing it. There weren't any visible cracks, but there were some discolored areas and other imperfections. I took some photos- could any of these spots be causing the failure? I don't know enough to really diagnose a break in the connection, I guess. Any thoughts are much appreciated!


contact points for one of the dead keys. looks the same as the others, though


a potential break? discoloration on the connection and maybe some residue


more of those darker spots on the connections. leaning toward this not being the issue though since there are more of these discolored spots than there are dead keys


i also noticed that some kind of solution or adhesive seems to have melted or spread out from these points and gotten onto the lines. could this be part of the issue?


more of that goop. again though, all of those spots get onto more connections than there are problem keys...

The other thing that occurs to me is that it's a pretty long way from the initial solder points for each key to the next solder point, and it's after several of the lines combine on the board. If I were to connect them directly, would that cause problems, since I'm bypassing the point on the board where the individual key lines are merged? I've been going through general info on soldering and circuit boards, but I haven't found a really clear answer.

Unfortunately, deoxit didn't help with the odd behavior of the filter cutoff fader. Here's a short video showing how the entire filter sweep happens in a tiny range in the middle of the slider. (unmute button is in the top right of the video)

https://imgur.com/3pAIG8Z

The bender adjusts the cutoff much more smoothly as the video shows, so I'm assuming that it has a separate connection to the filter circuits. Does this difference in behavior help to diagnose what's going on? Since the filter can respond normally, does that imply that the fader is the problem, rather than the filters needing to be recalibrated?

Thanks again for the suggestions last time I posted, I really appreciate it :) I'm very much a novice at this kind of work, but having a lot of fun trying it and learning regardless!

vsts are really the best value and by nature solve the interface problem that patching presents. it took me years to finally accept this. I would suggest money holing an audio interface and some sort of vst host (daw, tracker) first. of course being able to pack a volca in a backpack and make weird noises in the park has an indisputable merit as well

clean the rubber contacts and the spot on the pcb they make contact with using a q-tip and rubbing alcohol, same as you would for repairing a gamepad.

2nd photo is oxidation, I would -gently- clean it off, alcohol or deoxit sprayed onto a cotton swab or a paper towel. this is just to keep it from spreading, it really really doesn't look like it's eaten into the traces. you can check by manually following the trace to the solder points at either end, probing both ends with a multimeter and checking for continuity

same with the 3rd photo, though more likely that the trace has been eaten through. what's on the other side of the board? any leaking caps

4th and especially 5th photos are flux, the stuff embedded in solder or laid out on the board to get the solder to flow where it's supposed to. really shouldn't be an issue

check the cutoff frequency fader and see if there's any evidence that it's been replaced. an exponential potentiometer of the wrong value being substituted for a linear potentiometer or an exponential potentiometer of the correct value could explain the behavior of the cutoff. I -don't- think that's the case, but it is the first explanation to comes to mind. try and find a service manual. there might be a trimmer (fine calibration potentiometer) for the fader

It is a very deep rabbit hole but there are some affordable options. Most of the major bits of software go on sale fairly regularly, and if you hang around this thread for a bit the sales usually get posted here.

Just as a for instance, Iris 2 just went back on sale.

https://www.pluginboutique.com/product/1-Instruments/4-Synth/1303-Iris-2

It's a deeply weird piece of software, but really neat. And for $15 it'd be a massive bargain even if it was just for the sample libraries it comes with.

lol $134 off I see funky sounds software has the same sales model as steam. For $15 I grabbed this on a lark. I don't know what 99% of the features of this software do but it looks like it will make my keyboard produce even weirder sounds and that is exactly what I'm after. Figuring out the rest will be a fun learning experience.

edit: ok Iris 2 is like some kind of sorcery. This is way cooler than mixing two preset voices together

Yeah Iris 2, along with the Arturia synths that I paid for monthly via Splice’s nice rent to own system (which you can stop paying for at any time and then resume paying for it where you left off, no matter how much time has passed, and I think you don’t pay any more than you would normally if you bought it all at once), are the only soft synths that I uh legally own, along with some random max for live devices if that counts. But it’s such an insane deal at $15, I got it for $10 and I couldn’t believe it was actually that cheap.

You are entirely correct I haven't messed around with any of this stuff since the 90s and back then I was mostly just making midis to put into my RPG maker games. All these sampling and distortion programs are 100% new to me and I'm just loving them. I've been watching some youtubes on free plugins but any goon recommendations are more than welcome. I don't really have any particular purpose in mind, at this point I'm just looking for toys to play with that make a cool sound :v:

I can certainly share some of my old midis if you want that sort of experience. Many of them I made with a program called Fractmus2000 which randomly generates "music". usually it just spits out a bunch of garbled noise but sometimes it makes something that sounds neat. Does a modern version of this sort of thing exist? I guess I can still use Fractmus2000, it spits out midis and those are still the standard.....

I'd just like to say that the weird combinator modules in Pigments have alllllllmost made Reaktor redundant.


Also, my younger brother is looking for his first drum machine, he's a guitarist with very little knowledge of synths but has been eyeing up the Model:Cycles.

I reckon his best bet is something like the DR660 which has 'electronic' as well as 'sampled' sounds because one of his main criteria is 'can I Atari Teenage Riot bffff bfff bffff on it' (I'm so loving proud lol). He knows the difference between an Amen and a distorted 909 so that's a great start.

Thanks a lot! Really appreciate all the input. I opened up the keyboard again today and tested moving the contact strips around, and that doesn't seem to be what's wrong. I followed the dead keys' traces on the PCB and found that they are all grouped- each dead key is the last of a group of 4 keys on the board, and merge into one trace. After they're merged there's a spot of fairly heavy oxidation/corrosion on that trace, so I'm guessing that's the issue. Going to check it with a voltmeter to confirm and then hopefully a quick solder bridge will get the keys going again!

Haven't taken the sliders out of the case yet to inspect for out of place pots or issues with the filter control but that's next on the list

They’re not really related ideas, despite the similar sounding terms. “Wave sequencing” is like a super-duper arpeggiator/sequencer/modulation source. The actual sound engine of the Wavestate is just sample playback (it’s a rompler).

Wavetable synthesis sorta uses a slice of a sample as the source for an oscillator. It doesn’t actually sound like the sample… it’s hard to explain. It’s like Monster Rancher or Barcode Battler, but an oscillator.

Wavetable is bit like a BLT, but you can only taste one element of the sandwich at a time.

Seriously though, i found the best way to get to grips with wavetables is to find a 'simple' table of basic waves and hook an lfo up to it. That's no different to a subtractive synth where you change the wave with a knob and it slowly morphs from say a square to a saw (described more elegantly upthread).
All more the complex tables really are are more harmonically complex waves you then carve up the same as you would a sawtooth.
Think of it more as having quick access to a bunch of sounds that would take ages to make with FM synths etc.

Isn't it an old Sequential/DSI thing? Prophet VS? I'm definitely confusing it with vector synthesis but I wanna say VS capable synths w/ internal sequencers can also do wave sequencing, but maybe not vice versa. Anyway all this is to say the DSI synths w/ digi oscillators (Evolvers, etc) can do it too.

Never messed w/ the Korg implementations but the Richter and Harvestman ones are incredibly cool cause they morph the waves as they blend between them, so you get these totally fake synthetic harmonics w/ optional aliasing. Or just scanning through them which is also cool in a different way. The PH MK2 is a great thing to mess w/ to get an idea but honestly I wish there was a polysynth version of it, I wanna play it like a rompler.

If this is what the Korg synths are... don't tell me I don't need any GAS rn lol
