Klee, switched-on cables

Klee is starting to get cabled up!

I chose to go about it using flat cables: These result with somewhat as clean a solution as the “bundle method” which Klee build issue 6 manual suggest using, but without the added work stage of having have to bundle up the cables.

It’s been such a long time since I last did cable crimping, that I conveniently forgot how much I actually hate the task. Starting out it took me about 30 minutes to cobble together the first 8-pin cable! Subsequent cables of course went a lot faster.

Nonetheless, the vexing start made me think that it might be a good idea not to overly annoy myself with this. Build projects are supposed to be fun and all that, right? If I was to approach the work stage by, say, making a maximum of 4 cables per day, it should prevent excess of vitutus maksimus arising (pardon my finnish). This way I’ll have the cables sorted out some time early next week. Good enough pace for me.


Not too many cables installed, and things already look a bit messy..

Klee, starting out small

Returning to something way more DIY-ish after the off-topicness the other day, I figured maybe it’s time to officially kick off my Model 2 Klee Sequencer project. Thing is, I’ve had the bare PCBs for a Klee for over 2 years now, but I promised myself not to have yet-another-incomplete-project on my desk until I’ve completed some of the existing builds. Reckon that moment is here, finally.

For my Klee, the plan is to take the “design-route”. That is, get all the items needed before starting assembly and the put enough hours to measurements, planning and sketching. This way, I’ll hopefully end up with a fairly ready-to-assemble set of parts and be able to complete the Klee over a few build sessions. Spec-wise, its all extras/add-ons and sliders instead of rotary pots. Mechanically,  I’m thinking of doing yet another sub panel approach to hide sliders screws etc. and basing the panel design to Stephen Drake’s Klee. It looks like this:

..though I’ll aim for a standard rack unit instead of MOTM format Steve is using. If this doesn’t work out, then a desktop Klee should be just as fine.. Or maybe I’ll just add rack ears to have both!

Step sequencer

Parallel to building my TB 3k3 I had been, to some extent, getting acquainted with various sequencer designs. After taking my time searching and evaluating these, I ended up with a slightly modified Superseque schematic. This design, by Thomas Henry, is about as simple as it gets whilst still having a formidable set of features like sequence playing direction. I modified the schematic to include a second 555 timer chip as the original design relied on external sync alone. The sync source is simply selected with a switch. I also opted to use SMD parts where ever possible as this simplifies the board manufacturing procedure a lot, I get my share of drilling through-holes with the Vocoder project anyway..
