Hot Damn, My first SK-1 came in the mail! |
|
|
Nice!
Sounds awesome right out of the packaging. Been bending for years and have never even seen an sk-1 in person so i had to break the bank and get one on ebay.
I cant wait to bend it. I'm going to the hardware shop tomarrow and am going to have the cool old dude there saw me up some wood so i can build myself a cool case to put it into. I want this one totally modular style.
I cant wait! I promise to provide pictures and info on the progress of the project as it goes along! |

Cool! I've got one of those too. Haven't used it much lately but always thought it would be great to work out some sort of non-trivial hookup between it and my modular gear. I hope you'll post the results of your experiments! |

any tips or ideas on adding a sequencer to my sk-1? I was thinking of a blinking light circuit with relays to open close switches... but that might get kinda messy. better ideas? |

well production on this unit has been paused for about a week because ive been having a terrible time with ups getting a package i ordered from jameco. when i finally get the components i need, i'll do some more work and get some pictures up. |

alrighty an update!
So heres a picture of the layout of the controls so far... patch bay on the right, switch bay on the left.
Patch bay is pretty standard for sk-1s, some other points in there buy mostly just connected to the fat 3 chips.
Switch bay is nifty, pretty standard.
3 red buttons below the switches are loopers, and effect loop time. All three can be used at once
The knobs right next to it are pitch and then a trem->rez->distortion knob
Then heres the cool part, i built up a 555 noise circuit and implimented it into the bend. It doesnt do more than feed noise into the circuit board, but it trips it out. Tweak knob, starve, and level. a switch to control whether the 555 is fed into the board or right to the speaker, which kinda causes a strange mixing effect with the normal out put, pretty cool.
+ LED. Then theres a patch point which is connected to the control voltage input of the 555 (pin 3 i think) which can be used with all the other points.
Rest of the space will be dedicated to what ever else i think up. I want to include an LED blink circuit to run a vactrol but experimenting with it last night didnt really bring much success. The home brewed vactrol works fine, but it seems to just not be in the right range of resistance to be usefull. Going to experiment with replacing the led with a Relay instead.
So far, so good, sounds Awesome!!
Oh, and as much as i regret it, everything thing was eye balled, so drill holes are not lined up at all, hilariously slick

heres a picture of the relay circuit
Also, audio quality sounds great through my little roland microcube amp (100$ish great buy i highly suggest one) but when run through my recording set up sounds very distorted on the treble end. Wondering if this is a just an effect of the sk-1 not ran through the speaker cause the amp does some natural equalizing.
Also theres a high pitched quiet squeal through the line out which can be effected by the pitch bend that i cant get rid off. All my extra bends can be turned off so i dont think its a connection i made some where and am wondering if you sk-1 knowledgeable people out there might be having the same experience. Should i have grounded all my patch bay jacks or something?

Heres a jam i'm very happy with that i recorded when my girl friend was in the shower. just some small peak deamplification in poHeres a jam i'm very happy with that i recorded when my girl friend was in the shower. just some small peak deamplification in post.
Use of internal 555 noise circuit, filtering, looping, switches, and lots of distortion.

Great work! It's inspired me to have another think about modifying my own stock sk-1. To date, i have been reluctant to attempt anything because i would hate to break it.
They are such a great instrument- although the looping function is pretty archaic, one can really transform sounds in the lower notes.
How did you go about implementing THREE loop functions? |

used reed g's info on the bend points to find the first loop connection. the other two are other points that i found which loop as well.
They all loop just like each other except at different speeds, and when used in conjunction they change to even more speeds, or different loop times how ever you want to say it. I agree its a little much to include 3 loop switches, but i did it any way. Tonight im going to try and build up a rezy low pass filter schemmy i found and include it too.
Damn, the batteries on my sk-1 and going to dry up so fast, but im crazy!! |

Wow! That's great work! How does the patchbay work? Have you wired the inputs up to random points on the circuit? |

The patch bay works just like you think- just a huge switching matrix with access to hundreds of different connection through the use of rca jacks
Alot of the patch bay connections are hooked right up to the main 3 chips on the board. like on this page:
http://www.casperelectronics.com/sk1-patchbay/
But, there are plenty other connections that i randomly found on the board.
Im about to change the battery supply from 7.5 volts to 9 volts- hopefully it will go well |

this is probably against bender's code, but .. jeeze this project has become much more of a task than i could endure.... I am no wood worker.
The project is finished. It works fine, sounds awesome, but the wood and construction is in need of some fine tuning. Would any body out there care to finish it up?
I'd let it go for 200$ + shipping, thats not even covering parts.
It just taking up to much of my work bench...
all it needs is some clever reinforcement. Some way, that i dont know, that you could brace the control panel so it's not so insecure feeling.
Thats all it would take and you'd have the most monsterious circuit bending project i've ever endured.
Its a glorious machine. truely glorious. |
