Hey Scott,

Thanks for the tips. Work has taken me away from play for the time being, but I am looking forward to wiring up my SoundLab so I'll be ready for the Klee.

Cheers,

Andrew

That's a beautiful job Tom!
So colourful, so twisted, so Klee!
I'm feeling all choked up inside! Embarassed

Fantastic job, Tom! Congratulations! It looks great. I can't wait to hear it.
now get some rest...

Tom,

Your Klee is really beautiful! I am jealous of the slide pots!

Now the fun begins!!!

Regards,

Tim

I used to work for a sign company silk-screening...well....signs. I sucked at it, but in my brief tenure there, I had the bright idea of stuffing a rag in my left back jeans pocket. A rag that had been soaked in acetone. Biggest frickin' blister I ever had in my life, that was.

Anyway, outstanding job, Tom. I've got my proto wired up and running. Everything worked pretty much right off the bat, except the lunkhead that drew the schematic put a diode in the wrong place, making the random function not so cool (easily fixed on the proto). The manual step function wasn't nearly as nice as it was on the BB (to say the least), and I've got mine working perfectly now, though the fix needs to be confirmed on the other protos. Thank God for prototypes and prototypers, especially the guys that are working on this project. They're all aces. We all want to deliver a project that works the first time, and every time you power it up.

Anyway, the main problem I have right now is calibrating it - it's no problem to calibrate, the problem is, the Klee just won't shut up. I want to record everything, or nearly everything. And, even if it's disconnected from controlling anything, it's so damn mesmerizing to watch. Seriously.

For me, it's like a whole new toy - having switches one can flip and change things instantly is soooo much nicer than grabbing a wire with the needle-nose and moving it. And the pots - I don't need a tweaker to adjust the pattern voltage! In fact, it's so new to me, I find myself thinking "Hey, it shouldn't be doing that", then I realize it is, because I'm switch-bit, which can happen easily when one didn't have switches before.....might help if I label the switches, too Very Happy

Very Cool Scott!!!

The Creator embraces his Creation...and his heart is filled with Klee! Laughing

Oh, and such a blast it is! I'm learning new things about it, too, with the increased accessibility to the functions. In particular, I totally overlooked a simple fact about the Bus 1 Load function. The gate bus and pattern switches are pretty clumsy to finagle on the breadboard, so I tended to leave the pattern "switches" in a fixed position, and use maybe two to three gate bus "switches", never more. I never really got the chance to fully explore the permutations of Bus 1 Load and Gate Bus Switches with a variety of patterns.

I'd always thought the Bus 1 Load switch would be handiest with patterns containing a limited number of bits. With on bit, it acts just as a "reset" switch would act on a standard sequencer. With more than one bit, it was a very short pattern before a bit would hit the Bus 1 and cause a reload. So, I thought. The simple fundamental rule I overlooked was that the pattern would reload only when gate bus 1 transitioned from low to high.

In other words, if Gate Bus 1 is already high when a stage set to Bus 1 is selected, the Gate Bus 1 Load switch will let it "pass on by". With a number of active bits, the predictablity of what will happen if you're flipping Gate Bus Switches while Bus 1 Load is on becomes as amorphous as the predictiblity of the other functions. I just spent a good hour or two playing with that function - it's a sort of side-alley of the Klee I didn't realize had so much potential....

Cheerio,
Scott

Big cheers for Scott!

Supreme work!
(did the flu clear up?!! hehe)

I totally hadn't realised that Scott had been doing all the demo sounds before by swapping wires - totally amazing. And, yes, I can imagine the change when you get the sheer wonder tactility and play-full-ness of the finalized machine.

Yes, there's some bits to it that'll take some practice to control but oh my god its so damn exciting to play with! Clay indeed.

I really didn't get much time to delve into things yesterday (felt really spaced for much of the day - maybe due to massive wiring sessions the day before?!) - hope to get some time to work on it tonight. I know what Scott means about wanting to record everything --- this machine chucks out wonder constantly!

Well, I am happy to announce that I also got my Klee up and running last evening. Scott, I did confirm the double clocking issue using the manual step pushbutton. Interestingly enough, it's only the "B" group or LED's 9 through 16 that shift by two bit positions. The "A" register clocks with no problem. Externally clocking works fine with both registers "A" and "B" shifting normally.

I have clocked the Klee using both a PAIA LFO and a Blacet VCO using various waveforms and no compatability issues there. Clocking with a sine function at 0.2 HZ clocks the registers once per cycle which is good but probably would add the hysterisis anyways to the LM358 in case folks want to clock even slower.

I do have a small list of things I must fix. One thing I am experiencing is a strange dimming of all the LED's in group "A" when I flip the 8x2 switch OR when a certain pattern is in the "B" group ..... Have to look at that more critically tonight. The other problems seem minor like a couple of the parallel load positions for example.

So, it's getting there, just a couple of issues and I should be full up by the weekend Very Happy

Does this means we can order our boards?

With a 3mm spacer each side, they sit just right with a Behringer slider knob. (They'd be fairly standard/easy to get similar yeah?) There's space there for the main front panel to sit between. Cool

BTW, I assume some builders out there might benefit from or be inspired by my progress photos, but if any feel they are taking up space or are too obvious, just let me know and I'll put them in a separate thread. Smile

Don't stop, Andy. At least for me, this is very edumacational.
