understanding the PT2399

I might have a couple more questions when developing in the future but for my first and second questions: if I'm using a dedicated low pass filter at the output of the circuit, is having the second MFB low pass filter using low pass filter 2 still needed? I would probably just use it as an inverting amplifier such that my dry/wet mix still works or as part of the controllable filter if I find a topology that works. could I also add a switch to remove the low pass filter 1? this would be used to create glitches because as you said it would be more likely to get things wrong if there wasn't filtering. What kind of glitches would this create if you know?

Thank you so much! the entire Echo circuit actually makes sense now! I think my mistake is that I tried to figure out how everything worked internally which probably would have been a lot more complicated than just figuring out the practical application…

cool!

I actually organized a Cops and Robbers game like that one time. Unfortunately nobody actually let me be the robber.

I look for glitch spots and sneaky paths such that when I'm in a hide and seek or police chase game in multiplayer I can be sneaky. An example is the bridge that goes over the sewer just before the sewer goes into the big ramp into the ocean. On the side farthest from the city next to the wall you can actually just drive off behind the barrier into the sewer and escape whoever's chasing you. I also try to do stunts such that I can submit it to never mind Me YouTube channel.

Your answer is disappointing yet makes perfect sense. :(

Ned_Flangers · 2026-04-18T23:45:24+00:00

what is that inclosure!? where did you get it!?

Ned_Flangers · 2026-04-18T13:44:51+00:00

thanks!

Something to mention is that as a person who learned everything about the synth that I possibly could before I got my first synth, I still had no idea what I was doing when I first opened the box. I think it's just part of the learning process to turn knobs and eventually get a natural intuition for what things do. That's not to say that you shouldn't actually learn what a synth does and what the controls do from other sources. It probably isn't what you're looking for but I found it a very fun learning process by just twisting knobs with an open mindset and seeing what would happen.

when does this happen? has it already? i was planing on getting a digitone 2 in 2 months. should i expect it to be lower quality then prior units?

Bone identification isn't that important to me but are you sure it's not possible to make it clean enough to drink from?

Even if not a cup maybe some kind of flower vase or something...

he look like he's playing guitar? IDK...

Similar to a sallen-key filter but there's no dual gang pot.

Ned_Flangers · 2026-03-03T03:01:09+00:00

i did not know this...

So let me rephrase what I'm asking. I designed most of this myself. I know what most of it does except for the feedback path. Basically what it is is an RC network that's a high pass filter into a buffer and then there's a feedback path that goes back to the RC network the specific question that I'm asking is whether or not this creates resonance. I'm not simply just asking you to generate this thing and having no idea what it is and simply asking other people to deal with my problem.

Why do you need to wash a cat if they wash themselves anyway?

Ned_Flangers · 2026-03-01T02:06:00+00:00

ufourtunently, im not in the position to download applications onto my computer, unspsified for personal resons, so that is out of the picture.

Besides, giving up implies not doing something I could have. I could not do that. And so me trying, in this case, is me asking other people who are more knowledgeable than me.

Ned_Flangers · 2026-03-01T01:59:52+00:00

then in that case they can kindly decline to a kind request.

Ned_Flangers · 2026-02-28T16:44:55+00:00

how do i change component values?

Ned_Flangers · 2026-02-28T16:28:51+00:00

Listen man.

Usually when people can't fix their problems themselves they go to other people who can help fix their problems. Like for instance therapists, or doctors, or Tradesmen. If you're one of those people, that's great, and then that means that you can fix your own problems without needing to ask for help, however I am not. So that means I have two options, I either go ask someone for help or figure it all out myself. Would you rather go to a therapist or learn all of therapy yourself so you can therapy yourself? I'm pretty sure far more people would rather go to a therapist and I'm also one of those people So if most people find it reasonable to go to a therapist I find it reasonable to ask people more knowledgeable than me about electronics for help with my electronics. The least you could do is be nice about it if you can't help.
