How to get more out of analog delay - with Erica Synths Black BBD

Today we are going in depth with analog delay, using the new Erica Synths Black BBD. The BBD is a great sounding analog delay with a wide time range, thanks to a combination of two bucket brigade delay chips, and a lot of CV control over it’s features.
In this video we start with a quick overview of the new module, and then we dive into a series of patch-tips and ideas. From spacious stereo delays, to using a delay as a sound shaping tool, and finally some patches to create drones and textures with a delay. Hope you enjoy!

You fill a need in the eurorack community! When I look at other KZbinrs explaining their patches it can sometimes be hard to follow. I may not be familiar with their modules, and it’s hard to follow the patching cables. To be able to actually see a diagram with your great explainations makes all the difference. Much appreciated. Keep up the great work!

[@MonotrailTechTalk]

Thank you so much! I was hoping the patch graphics would make a difference to people. And iI will continue for sure :)

Planogram's (block diagram) are so inviting and clarifying the path of the signal, it is awesome to follow and understand with ease, each and every video you create. P.S. love this module, and all firemans bucket brigade idea behind it 🎈

[@MonotrailTechTalk]

Glad you liked it! Cheers :)

[@claudiodellaragione2653]

Your vids are really useful and inspirational especially for a newbie like me. Easy to understand but deep enough to keep the attention high and straight to the point without useless talking. Last but not least your music is dope. Thanks for your efforts. Greetings from Italy.

[@MonotrailTechTalk]

Thank you so much! This channel still feels like a pretty new project for me, but getting these kind of sinsere positive respondses really makes it worth it! All the best to you :)

[@SyncdAlien]

You sure gave us a bucket of delay ideas! ;) Liked & shared!

[@MonotrailTechTalk]

Hahaha XD Thanks!

[@micowata]

Great video, thanks ! Love the sound of BBDs and their pitch shifting ability. Very glad to see more and more of them in eurorack.

[@MonotrailTechTalk]

Thank you! And indeed, very flexible devices to have in a modular format :) All the best!

[@MR2GR]

Dude, I got into modular the beginning of this year and it's been great, but even this video surrounding a specific delay module has given me so many ideas just because of all of the patch diagrams you show. Thanks.

[@MonotrailTechTalk]

Hey, glad to hear it! Always try to make these videos useful with wide ideas. It's really motivating if people let me know it's working, so thank you!

[@JohnLRice]

Excellent demo! 👌😎👍

[@MonotrailTechTalk]

Glad you liked it!

[@mymodularjourney]

BBD are so much fun.

[@MonotrailTechTalk]

Indeed! Really versatile tool as a module :)

[@A_S_M_R]

I just got this, it seems to be very noisy, do you find this to be normal? I notice some high pitch whine in some of your patches.

[@MonotrailTechTalk]

Hello! And yes. Analog delays like this and many others like the Doepfer ones etc use an internal high speed clock to create the delays. this clock is audible in the sound. For this reason there is switch to set the 'brightness' of the delay. But this basically applies a filtering to the output to filter the high clock pitch. The longer the delay time, the lower the clock pitch, and the more you need to filter it. On purpose I showed the direct sound of the module, but often it is advised to put a filter behind an analog delay to be able to filter the clock noise with more precision. In general though analog delays like this are not my choice for clean long delays, there are a million digital options for that. But think they are great for dark and gritty sound design and effects when modulated.

You could also make a karplus strong patch with the bbd delay, but without 1v/oct input on the delay frequency it wouldn't track well but still pretty cool

[@MonotrailTechTalk]

Yes! I actually thought about incorporating that in the video but thought it would take a bit to much time to go in-depth with karplus strong. Might do a seperate video about that in the future, and would use this module for it for sure! All the best :)

[@federico8918]

@@MonotrailTechTalk you're right, karplus strong is not the most intuitive patch at all

[@patienthands]

Nice video but I wish you had shown what the switches do to the sound!

[@MonotrailTechTalk]

Thanks, and yes, that would have been worth it, sorry!

[@rexterrocks]

A BBD chip is not analog as people keep wrongly saying, it's an analog/digital hybrid because it uses a digital clock. Without the digital element, they wouldn't work.

[@MonotrailTechTalk]

Im not into the mechanics to be honest, but that's probably true. Most "analog" synths have a lot of digital control elements like LFOs or envelopes, but still are called analog because the audio path is.
