A fellow electronics enthusiast I see. Pretty cool here. I'm not always too keen on these sounds since they tend to sound a bit primitive, however, they certainly add a certain characteristic that stands out. Nice job. What are you using as the main board? Arduino? I checked your profile and see you also use ChuCk. There was a time when all I used was ChuCK (and other apps): this might be interesting to you:

Very old work. But all done in ChuCk with some things being done in post.

Anyway, pretty cool.

Hi siensystem, The board has two components: A dual Boolean Sequencer and a pair of Karplus Strong circuits. The BS generates a binary count and sends it into logic and resistors to make control voltages of long sequences. The KS performs string synthesis, which generates sort of guitar-ish and drum-ish sounds. ChucK is a major tool for me, I've been coding in it for nearly three years now. I modeled the BSKS circuits in ChucK before building them which helped a lot. Thanks for the video link and I'm glad you liked the track. Thanks.

Interesting. Reminds me of some of the old original Moog records I have. Kudos to you again man for making your own synths!

Being compared to Moog is a compliment of the highest order, thanks! You made my day.

Awesome track! It's cool to have another electronics builder on the site! This song sounds pretty cool, I'm curious what chips you used to build this little synth. Nice one! Welcome to Looperman!

Hi Spivkurl, the Boolean sequencer is made of LMC555, CD4040, CD4070, CD4073, and TL074 chips. The Karplus strong is made of LMC555, BL3102, BL3209, and TL074 chips. Thanks for the warm welcome!

awesome to have home-made electronics like this in the looperfam - very pure, coolly twisted!

Hi Inventor..and welcome to looperman!...interesting sounds,what are you using as a controller? sounds like a rotary device,as opposed to a keyboard with octaves,there's a couple of circuit benders on the Loop,SpivCurl to name one...I've always found electronics interesting but only profess to know a little guitar circuitry and basic amplifier maintenance...behind every inventor lies an inquiring mind and untold projects I'm sure...nice to have you aboard!..cheers planet :)

Inventor replied Unknown - 2028 years ago
planet, the controller is a Boolean Sequencer, which is a clocked binary counter driving logic into a resistive summing network. I know, technobabble, but that's what it is. I can explain further if you're interested and ty for your comments.

Funny stuff. Not really a song but great loop to fool around with. You can create really funky loops with some drums.

FDV, I posted a second song that has the same boolean sequence but percussive operation of the Karplus Strong circuits. The two can be mixed together to create a song with two drum and two guitar voices. Hope that helps.

Description : EASE. Propella Head.

Dark atmosphere meets melodic lift in this upbeat roller from EASE. Deep bass and a driving groove keep the momentum moving, while the melody brings an emotional pull. Propella Head draws you into the shadows and keeps your feet moving.

Description : Heavy, but you can still dance to it. The kind of industrial from the Chicago Wax Trax era, bands like TKK. At least that's what I was aiming for.

Description : We used to ride all night thru downtown Chicago blasting Return to foever in Marks 72 Vega with 12" Ventura BIC speakers in the back that were chrystal clear. i was still too young to drive. Those were some of the greatest times I ever had I'll never forget that band the bandmates or those times. Mark out did himself on this Re-mix/Master. He also updated the Drums, makes the track feel brand new, even tho it's 4 years old.

PEACE...

Instead, here is the instrumental to the work. I'll put the uncensored version somewhere else.

also i got a new pair of headphones again this time at the advice of some good engineers i went for some planar magnetic. some criticism of the mix would be appreciated
