Re: Report Forum problems here
You are probably aware that you can manage these settings from the User Control Panel. Screen Shot 2020-03-20 at 12.36.36.png I am, yes. The problem with that is, that I can never work out where those settings are - there are so many different tabs. I even had trouble finding the User Control panel...

Sorry for reactivating this... hm.. let's call 'old thread', but I can't resist! :lol: Don't be sorry. I'm sorry I wasn't aware of your post. IMIHO, there are no old threads, and there is no old music - only old musicians. As Arlo Guthrie famously said "One big pile is better than lots of litt...

I haven't been getting reply notifications - a common problem on forums.
I did get notified of a thanks, by modman (thanks for the thank ) so that may be the best current way to get a reply to your post - thank the person you want a reply from, with the thanking thumb button.

Re: EHX - Bass Metaphors [gut shots]
Sorry for my lack of adequate ability to speak - and especially understand - any other language than my own. Language education in Britain was appalling when I was at school. Maybe it still is. They were wasting everyone's time but their own - but kept claiming we were wasting their's. I have a good...

Re: EHX - Octave Multiplexer [schematic]
Fair enough. That really does sound like either a faulty component, or a dry joint. Both can be very mysterious. Do you have another LM324 to try? Or any other quad op amp with the same pinout... they mostly correspond well enough to just swap them out. I think the only really significant difference...

Re: EHX - Octave Multiplexer [schematic]
Yep, that's pretty weird. I would guess that the circuit, as drawn, can't do that, so something is different. By turning the Blend knob a little, I think the main thing you're doing is putting some resistance between the output of the first op amp in the chain (IC1d, in Bernardduur’s schematic) and ...

Re: EHX - Octave Multiplexer [schematic]
Maybe you could narrow it down to a general section of the circuit. For example, with Blend all the way to the "clean" setting, does it ever happen, or maybe just very faintly? Because of the way the Blend knob works, there's always a chance of some small leakage from the effect, but if th...

Re: EHX - Octave Multiplexer [schematic]
Fair enough. I can't claim to completely understand the circuit, but it seems like an odd choice, to me. Even so, the sound of those caps charging up from a standstill would probably be more like a click, or a pop, I expect. I recently bought a Mosky SHO Booster clone, which is MOSFET based, as I un...

Re: EHX - Octave Multiplexer [schematic]
Excellent. I'm glad you've got it working. Yes, ideally, you'd strip all the harmonics / overtones off the note, but a guitars tone control doesn't track with the note, so if you set it right for the low notes, it will mute the higher ones. Restricting the range with an EQ pedal does tend to help, t...

Re: EHX - Octave Multiplexer [schematic]
Correction to what I said earlier - a bridge rectified signal would sound a bit like a distorted octave up, not a half wave rectified one.

Re: EHX - Octave Multiplexer [schematic]
Okay. Top left is fine - that's just more stabilisation of Vref and power smoothing. R7 being reduced from 18K to 15K, I would guess is just someone's preference - or someone didn't have an 18k resistor, and tried that instead. Probably not much difference, but maybe worth experimenting with if noth...

Re: EHX - Octave Multiplexer [schematic]
The idea of the LM324 is that it behaves a bit like a bridge rectifier - the positive half of the signal goes one way, and the negative half goes the other, but one half is then inverted. The two separate pieces flip the Set/Reset latch side of the 4013, to produce the same frequency square wave sig...

Re: EHX - Octave Multiplexer [schematic]
The schematic I've been looking at is the cleanly drawn one posted by Bernardduur, near the bottom of the first page. The only thing it lacks is labelling of the pins of the 4013. I'd suggest sketching that out from the datasheet, to help understand it a bit better, but mostly what you're looking fo...
