Super Klee Sequencer

LM324's work, so that means as soon as I update the Gate Bus schematic, that one will be in the can as well. That leaves the final CV mixer schematic, and that'll be all she wrote for Model 2.

Once the schematics are done and Uncle K has completed his stripboard layout, I'll go through and renumber the ref des's to match it - that'll also make a good second check on it before solder is applied. I'll put all the schematics into one package so one doesn't have to traipse through this thread and figure out which schematic is the latest, etc. I'll also mark up connectors and write up a cal procedure, as well as operating tips and control descriptions, etc.

Then it's on to Model 3 =0).

G'Night All,
Scott

I haven't looked at the gate bus yet. The stage connections on the encoder schem have led me on to the scaler/decoder which will be the next one (including the buffers from the encoder) With all the 4066s to go on there as well as the multiturns, it could easily take up the next board.
I'm gonna have a couple of days off the Klee though, my Sorcerer is getting lonely. You're a bad influence on me Mr Stites! Cool

Uh, oh - did I break this thread? My computer accesses the schematic full size without me actually clicking on it. Embarassed

Mine too - you broke it! Razz

Awww! That's tragic!
Never seen that one before... Laughing

it's probably a bug never seen before because no other thread had pictures on page 8 Shocked

Minestronics! I am shocked! What a brilliant title for an album!

Cool

I love word-plays like that; now I have no choice but to listen to the music as well... Very Happy

hi scott,

i wonder if you draw the schematics in ExpressSchematic, don't you? so do you mind (in this case) to include the files in the final zip? this would enable me to design pcb layouts without triplechecking of the redrawn schematics...

cheers,
matthias

Same thing happened to me when I tried putting the stripboard up first time. Just remove the attachment and then add it again.

Thanks Uncle K - aaahhh - that's better.

Actually, unless Ken Stone or someone else gets permission to sell pcb's, I would myself rather build stripboards Kruckus-Style, cos all that drilling would kill me! Shocked

Wait till you start putting in those 84 wire links!

I for one can safely say that I am very scrupulous. I also have a large amount of ruth. Maybe some half asleep production line worker inserted my lie chip the wrong way round, 'cos I think it's been fried! Laughing

i played a little with the front panel designer (schaeffer) during lunch brake and that's what i came up with, a 19''/3U frontplate:
- update 10 oct 06 -
"the gate grid" and the frames make this panel expensive, they can easily omitted. the holes are 7mm for alphapots and 8mm for cliff 3.5mm jack sockets...

That's a very nice looking front panel. Smile

I don't know where I'd get "Mouser" parts.
I think the stripboard vs. PCB question is pretty much 6 to one, half a doz the other. I'm all for people to have the choice. Some don't like links, some don't like drilling, some don't like trying to fault find stripboard, some don't want chemicals around. It all comes down to what you know and are used to.

Of all the people out there doing this kind of stuff, I admire Ken Stone and Ray Wilson the most. They not only provide PC boards, but also make the schematics freely available. If one wants to build one of these designs, one doesn't necessarily have to purchase a PCB (though it quickly becomes apparent that using a PCB is often the most expedient method of building the design). In any event, one doesn't have to shell out $$ just to learn from their work, the volume and uniqueness of which is xtraordinary.

Fonik, that panel is just beautiful - far better organization than my mind has been able to conjure. Missing though is the rotary range switch I forgot to mention in my message to Coriolis. Actually, I've got some rotary switches from Allied that are really spiffy, no larger than a pot. Comes with a knob that's a bit smaller than I'd like to see, but still, it takes no more room than a pot will. I'm very thrilled to see you put in the "Shift On/Off" switch - that's a detail that should be put into the schematic. It is a very important control in the grand scheme of Klee programming.

The final schematic, CV mix, did add some additional controls and connectors. After seeing this panel, I'm thinking better of it.

These extra controls can be considered optional - they conform to how I've been using the Klee to make all of the samples.

The additional controls (3) and connectors ( Cool

are:

A Modulation Level
B Modulation Level
A+B Modulation Level

Modulation Input
Master V/Oct Input (mixes V/Oct signal with all three outputs)
A V/Oct Input
B V/Oct Input
A+B V/Oct Input

A Output (bypasses lag)
B Output (bypasses lag)
A+B Output (bypasses lag)

Most of this stuff can be accomplished externally, though it requires additional patching (bypassed lag outputs would not be possible with external patching). What I will do is put out a version with the basic architecture as displayed in this front panel (which looks really, really nice, but needs that one extra control), then do a version for those who want to throw it at the Kitchen sink. It can be the Klee Model 2 Deluxe or something like that.

Speaking of the range switch, I've found that the 1/12V and 1/6V ranges sound better on paper than in real life - at least for me. There's always the danger that someone could find a really snazzy app for them and I've done away with it. However, those type of sequences would still be possible, but it would take slightly finer tuning than just cranking pots. I'm looking at experimenting and having, say, ranges that program thirds or fifths just to see if that makes anything more interesting with the pots cranked. None of that will affect any Krunkus stripboarding operations - it would just change values of resistors and trimpots. Suggestions appreciated.

Cheers,
Scott

fonik - your panel looks great!

i have one comment though: the 16 knobs should really take up more width of the 19" rack.

last night i laid out 16 rean knobs (like blacet uses) on a 19" panel and it seemed to me that having around 35cm is a nice comfortable width.

cheers,
michel

Don't be shy about changing the range controls. I realised the other day that when I came up with those fractions, I didn't really understand the range control function! Rolling Eyes

At the risk of blowing things up again, here's the standard, 'simple' output section of the Model 2. It follows what Fonik has on the panel.

I'll finish the ridiculous 'deluxe' section and post it as well.

Cheers,
Scott

first i just want to say thanks for the positive feedback. i'll add the missing control tomorrow. it controls the range of the pots, am i right? so it should be placed in line with the programming pots (which seems not easy to do) or it can be placed in the cv out section (which is not that good but easier to do)...
