have you tested the circuit or got the pic code assembled yet any progress on this project .would love to know. cheers ,glenn. ... voice and audio 1 out....
Just writing up a detailed guide of how to add it onto all of the Sk's. I'm missing some vital information, but i will put it on here as soon as it's ready. x...
The 500k pot the Ghazala uses is going to give you more of a swtich like on/off action because it's 100 times more than what you need! I'm not sure why Ghazala...
Graham- I'm protoboarding the simple VCF right now. I downloaded the "VCF with res CV in.doc" from the files section. I'm noticing that the schematic is a bit...
Hi all, I recently got hold of a boxed SK-1, and it came with a cassette of 100 sounds produced by the Hal Leonard Company for sampling into the SK range of...
Hi Justin, The schematics on Tom's page are correct regarding the 1M resistor. Tom's site did not have a board layout. The error I found was in the board...
Thanks, Graham! Now that i look at Tim's original schematics, i see that the schematic in the files section here is the self-oscillating version (as you said),...
I'm building a sequencer circuit to trigger bends on a instrument I'm working on using the 10 channel led sequencer ( modified so it's 4 steps) on this page ...
Hi / hello, hope you're all well.... I've been lurking around this group for a few months, reading the occasional message and slowly awaiting the time when I...
Hi David, It should run fine off that power supply. The chip in the circuit can handle up to 15V so the 505 should be ok. Just one thing regarding the CV input...
Thanks for the reply Graham, for some reason I thought that the schematic stated 5volts. I can see now that it does clearly says 9 volts... so no problems...
Hi david, You may have actually seen a schematic of the circuit somewhere with 5V labelled on it. But the components are rated to take up to 15V, so long as...
... David, the caps you purchased will be fine. As the (self-appointed) official electronics engineer of this fun bunch, I am pleasantly surprised to say that...
Just a quick question prior to bending my sk-5 - I remember reading something a while ago, can't remember where. . basically it was related to a point on the...
Anybody tried this? I got it to load my own samples from the ROM. I don't have an EPROM burner at the moment but that is all you would need to make it...
Hey, I was wondering if you can load besides an EPRPOM, could you load a digital recorder (I.E., samsung or RCA recorder), I think that it would be easy as...
I don't think it would be possible to do that. The data formats are totally incompatible for one thing. The ROM chip it uses is a standard 28-pin 27C256, with...
Very cool! I always knew this should be possible. I did the same thing with an HR-16 drum machine: http://burnkit2600.com/gear/hr-16-diy-sound-roms/ I talked...
Dave- I think it's the SK-1 you're thinking of. The one-key play. -justin = burnkit2600.com = ... basically it was related to a point on the unit where a pulse...
The cool thing is that none of the program data running the microprocessor seems to be stored in the mask ROM on there, only the sample and loop/envelope data....
Yeah, stormscorner Jesse. He's also working on a program for writing custom sample roms for the HR-16/HR-16B. Another guy who goes by the name of GordonJCP has...
Has anyone seen what this guy has been doing? http://www.circuitbenders.co.uk/forum/index.php/topic,651.0.html Amongst his stuff, one of the things he was to...
So my friend gave this to me because he said it was broken. I put some batteries in it and found it worked alright except it put some garbled glitchy noise at...
Hi, I need a little help regarding Graham's VCF - I've been a little foolish and soldered the components onto my stripboard without cutting the track on the...
