Fascinating indeed! For me it was the exact reverse! Up until about 15 years ago I've always been a very small fish in a big pond, and even when I joined this latest (small) company I still had the same mindset. That was until I came back from a job really excited about having sucessfully repaired a ...

Hmm.
I wouldn't be inclined to actually short the input, just in case the noise source is a noisy input bias resistor! I'd just stick an 'empty' plug in there to giver some screening.

This is the sort of repair a half-decent engineer could almost do blindfolded! it sounds to me like they screwed it up somehow. Quite likely they used brute force on it and cracked the trackwork in the vicinity. Get it away from them as soon as possible and hand it to someone who knows what they are ...

Same here!

I'd really like to hear it live, played side-by-side with a conventional piano (fat chance I know).

They collude with each other you know... so-called 'inanimate' objects.

Sort of relevant-ish...
I remember hearing someone saying that only a child will eventually be able to get the best out of any new instrument. It's creator never will. I guess that applies to making presets too.

Your link had a bit missing off the end, but I've made it clickable here.

Can't offer any help myself but I'm sure others will be along soon

In a word, buffering.
Preventing from one source interacting with another.
Allowing a lower resistance pot, thus reducing noise.
The final buffer prevents the next bit of kit changing the behavior of the pot.

One of the issues with overclocking is stability. If you're just browsing the 'net you might not even notice a few errors here and there, but do you want unpredictable behavior and Xruns in the middle of an hour long 24 track recording?

Depends a lot on the manufacturer (and the phase of the moon), but one of the risks is that if some external source is feeding a voltage back at the time the chip is powered up it can latch up... fatally. Another is the usual electrostatic discharge which I believe is actually more risky when there ...

Thanks Nathan, that all appears to be consistent with my observations. The Minibrute gate schematics are on the hackabrute site under Digital > gate in/out. (Off-topic, I have asked Yves, the owner of the hackabrute site and designer of the Brute's analogue circuits, and he confirmed that the ...

If I want 'standard' sounds I'll go straight to the presets - why re-invent the wheel? Otherwise, for that special sound that I can hear in my head, I'll find the closest one to it then tweak it till it fits. If I'm bored, and totally lacking in inspiration, I'll fiddle about from scratch. A number ...

Yep you've got it pretty much right. Considering those figures, you could actually solve the problem with a simple transistor as an Emitter Follower powered by just about anything over 5V (PP3 if you've nothing else). The Base goes directly to output of what is doing the driving, and the Emitter ...

It's probably a combination of voltage and loading. You did off load measurements. They may be very different on load. Also, it's not unknown for for the destination to want to pull up rather than down. I would suggest a buffer stage of some sort would solve the problem. Possibly an OpAmp that can ...

A switch? A ***'king two pole switch! I'm disappointed in you Wonks. No creativity there at all :tongue: At the very least you could have used a transistor. Better still, an OpAmp with a nice little ramp circuit so there are no current spikes when the LED turns on or off. Hows about a cute cap ...

Use cat5e or cat6, ftp (foil twisted pair), slightly more expensive but worth the difference.

I have schematics yeah. I'll post 'em tomorrow. Half the problem is I'm trying to wing it by guessing and not actually taking the pedal completely apart #lazy

Go and stand in the corner facing the wall

It works because the tension in the curved parts of the cable forming the knot act like springs which absorb and damp vibrations passing along the cable, and thus reduce the amount of mechanical noise being passed into the earpieces. H See! That's why I come here. Fascinating info I simply would ...

You should be able to disable this as it's an alternative driver, not a replacement. I seem to remember doing this quite a long time ago but can't remember the details. As with any OS it's a good idea to have a disc image program so you can restore to a known condition if/when you screw up! In Linux ...

Good decision. I'm a great believer in:
"If it ain't broke, don't fix it."

Ooo. A car analogy. You should'na done that :D I'm sure everyone is familiar with Microsoft and Apple cars, but Linux ones are a bit different. Linux embedded car You get a chassis, engine and basic steering rack - no brakes. Anything else you want you need to build yourself. Linux server car All ...

Agree Mint is usually a good choice for new users. Mind you, I generally have flash blocked anyway

PCLinuxOS is another good one, and usually bang up-to-date http://www.pclinuxos.com/

I just have to ask... why?
There isn't much that would benefit from a 10M load, and it tends to cause all sorts of other problems.

Thanks Folderol. So is R70 perhaps the one I should have gone for in the first place? I thought that, as it was just feeding the input of U5A without a capacitor directly in series or parallel, it wouldn't have a role in frequency shaping. But from what you say, it must be interacting with C32? No ...
