Thanks, it was a struggle to keep the digital switching noise quiet with three square wave tremolos constantly popping at once. I simplified it to one delay line crossfading with the clean signal, nuked the pops with big capacitors and it works pretty well - th-cam.com/video/FucNjteCpCg/w-d-xo.html
I'm still trying to nail down a PCB design for this pedal, but when I do I should be able to sell the PCBs for DIY projects. It's pretty complicated with the three delay lines, but I expect the PCBs to be mostly SMD components and assembled by machine so most of the soldering will already be done. Hopefully that'll make it an easy project although comparatively expensive for the boards
@@glowfly thanks for the reply. I look forward to the PCB. I wonder what kind of result you could get with maybe throwing in a few 555 timers or a cd4093?
@@Mostlyemptyspace You mean to glitch the LFO patterns up more? Sounds fun I'd like to hear it! I'm using a micrcontroller so I could chop the signals up in all sorts of crazy patterns but the problem is how to control it (i.e. what parameters to assign to knobs and switches) while keeping it intuitive and musical. It could very quickly get out of hand haha
This looks insane in the best way! I'm thinking 3, regular knobs for blend, time and repeats, and maybe two, large knobs for speed and depth of the tremolo circuits? And then some really tiny, micro knobs for any other necessary parameters.
I'm feeling the 2 big knobs (not a great sentence) for speed and density. Sadly I think I'll forgo any kind of feedback control, resending the signal through the choppy tremolos grinds it into a fine powder that sounds pretty nasty. I had some PCBs made but the control voltages from the microcontroller caused audible poppiing, so I'm working on a simplified version for now. Thanks for your feedback!
I agree that density seems like a useful control. Tap tempo seems more important than tap division. I don't think tap division is worth the space on a more experimental pedal like this one. I don't picture people using it being like, "Man, I wish I could get this thing to hit on the quarters instead of the eighths" or whatever. I could also be misunderstanding tap divisions though. A dry trem could be interesting. Where in the chain would that be? First? Would it work in tandem with the delays and the trems that follow the delays, or would it be an either/or setup? At any rate, this is gonna be rad.
Cheers! I'm pretty settled on the Density knob. The plan now is to have a switch that flicks between two modes, each mode has a different purpose for another knob (rate / tap division) and a footswitch (max density / tap tempo). Yeah that's how I'm seeing the tap divisions. I want to include it mainly cos the rate knob would be useless in tap tempo mode. Still need to update the code with this feature.. Adding tremolo to the clean signal is a cool idea! Then you'd have 4 points in time to skip between. It might be too late to add it to this version though. An issue that might crop up is that, because the delayed signals get low pass filtered, the clean signal might stand out a bit awkwardly... but I'll definitely have to try it! :D
Hopefully this isn't too big of a disappointment but I didn't include pitch modulation in the recent design. I tried to on a previous PCB but there was too much going on to get it working effectively. Pitch-mod on PT2399 delays is always a bit user-hostile anyway, as the depth will increase with delay time. I'm hoping the extra glitchy features will make up for it!
@@glowfly Kind of a bummer. That one was a fav, but I can get pitchy weirdness on ct5 and whatnot. Still, hearing it separated granularly is definitely interesting. Either way, this pedal will be cool. I'm psyched to see what you're coming up with.
Yeh I should have PCBs eventually! Just trying to figure out which possible controls I can sacrifice so it'll fit in something smaller than a 1973 volkswagon beetle
@@glowfly if i had one i would definitely build one inside ;) cool. Will the microcontroller also be available? Put This is in the effects loop of your mixdown and you can make anything sound sexy. Have you tried it on voice?
@@bleepboxes Yeah I'd include any parts you couldn't easily get elsewhere. It may end up being majority SMT and factory assembled, depending on how simple (or not) the circuit turns out to be. Will save you some soldering at least.
@@alexkhughes I like the idea. I've often wanted to use dipswitches somehow, but I could never find any that didn't look flimsy. I wonder which ones Chase Bliss use.
This is like a mad scientist experimenting with the guts of a robot 🤖
This is gold
Just Got my glitch delayyyYyYYYY in the post , this is Gr8 with everything.... I will load up the other patches in the future. Cheers
this is such a cool circuit. very cool idea!

This sounds amazing! Very cool, looking forward to seeing more
WOBBLY GOODNESS
This is really great. I like the Density controller, a lot.
Fine. Take my money.
Rad! This is exactly what I was looking for to make! What would you guess the difficulty level to be if one were to take this project on?

@@glowfly Ha ha! You're welcome. Looking forward to seeing the end result!
Do you think I could use something like an attiny85 instead of the microcontroller you’re using here?
Sure that'd work. You need one digital output for each delay line. I was using PWM for the pitch modulation

I can probably mod the recent PCB & add pitch control. Just wanna get it working first!
Very cool! Looks like a fun device for messing around with in the studio. Are you going to sell pcbs?

@@glowfly What about dip switches to allow 2-3 controls on one knob? Not sure if that would be easy to implement, or even practical though.
