Finally!
I actually paid for this almost two months ago but the seller had no way of transporting it to me since he had no case for it. And, he lives over 600km away from me so it's not really a quick or cheap trip with the car to pick it up.
Yesterday though, I finally got it :)

Terratec Phase 22
Just a short notice about this one. It's a PCI ASIO audio interface.
I bought it new, I think around four or five years ago.
I don't have a picture of it (it's really nothing to see).

Step4x16 addressing test
Not much new to report but it is so much fun to see your project actually make something visible and audible happen :)
I have tested the address decoder and data latch mask logic. A small video clip was made as well just to show the amazing LEDs :P

Some 4x16 prototype testing
After a couple of weeks (isn't it?) of programming, testing and being lazy, I finally managed to get the sequencer running.
I have now managed to trigger the CS-30 and send CV voltage thus producing a somewhat musical scale :)

Why does everybody hate the Poly 61? Even my cat..
Well, I'm gonna spare you most of the details. But..
One of my cats just puked on the keyboard of my Poly 61.
Come on! No synthesizer deserves that kind of disrespect!
Luckily it was easy to clean off.
Any negative comments about cats will be removed.
I love my cats.

Microchip AN556
Well..
This isn't really only related to my sequencer, but since I'm programming a PIC to use with it I'll tag it as Step4x16 sequencer related anyway. Oh, I changed the name of the sequencer again to "Step4x16". I found it's the most logical name since.. well.. it's got 4 patterns with 16 steps each..
Anyway, there is a bug in Microhip's application notes "AN556 - Implementing a Table Read"...

More sequencer planning
-"I will try to buy as few components as possible"
Who said that?!
Ok, so I had a feeling from the start that this would rather turn into a "I hope I can use some components I already have" rather than the above...
I spent a couple of days trying to fit the panel layout to a plastic sweets box. I made a layout in InkScape.
LOL the background is transparent.

Make a small CV/Gate sequencer?
This is too much, I know.
But, when you have a CV/Gate-synthesizer, don't you just feel the urge to try and make a DIY CV/Gate-sequencer for it?
So, there's a new project in the making! But, this is more than a possible future plan (like the Juno and JX-editors).
It'll be waaay simpler than the Matrix-1000 editor so it should be a lot quicker to build and program. Preliminary name: Mörckstep, in lack of better ideas...
I want to keep it simple, yet flexible, cheap and easy to use.

CS-30 Sequencer KBD mode tuned
Well, my calibration skills (or rather, my crappy multimeter) seemed adequate enough to fix the problem I had with sequencer set to KBD mode.

I'm not dead, just demoralized
Ok, I haven't been writing anything for like three months.
The reason being the problems I had with the A/D-converter. There is still a lot of jitter on the lines which sometimes causes a parameter to constantly switch between two adjacent values.

After buying rack units I need to use them :)
Ok, recently I have been buying a Matrix 1000, a rack mixer and 3 rack FX units. Time to put them to use I think? I got myself some screws (couldn't find any black ones) and a lot of patch cables and got to work.
More of the same!?
More FX!
A rack mixer?
I never thought I'd use one but realizing I have very limited space in my small apartment and since I have two Matrix 1000's that need some mixing before going to my regular Behringer Xenyx 1002, I thought, why not? With a price of about 30 Euro it wasn't really anything to think too long about either.
A Roland M-120 12 channel line mixer! :)

Replace Poly-61 battery with Lithium battery
Just a quick update. I made a small board out of strip board and placed a holder for the coin type Lithium batteries that are so common (CR2032). I put a schottky diode in series with it to prevent the reverse charge current.
I'll just put a photo here and then if you're interested you can read the rest of the boring details :)

Built data entry knob stuff
Well, not much to write about actually. I have just built the design I made earlier but not yet mounted it or even tested it yet.
I made the strip board design using a program called Loch Master 3.0 available from http://www.abacom-online.de/uk/html/lochmaster.html for €39.90. A very good tool for planning your strip board projects!
Here's what I came up with using the program:

Another Matrix!

Good progress. Prototype done.
I got myself a programmer, some PICs and started to learn. I had to do the compulsory "blinking LED" but after that I continued to see if I could do what I wanted.

Maybe a data entry knob for Poly 61?
I have been looking for a reason to learn PIC programming for a while. But, with my Matrix 1000 editor project, a PIC really does not have much contribute with compared to the LPC2103 ARM7.
However, a few nights ago I was thinking that it might be nice with a data entry knob on the Korg Poly 61, similar to the alpha dial on the alpha junos.
Perhaps a suitable job for a PIC?

Boys say go! (A simple cover)
I was bored this morning (night almost, woke up early) and was thinking of the Depeche Mode song "Boys say go" version performed at the Hammersmith Odeon in 1982. It's better than the album version (Speak and Spell).
Without giving it too much serious effort I decided to do a "remake" more than a cover of the song. I mean I wasn't trying to change it a lot. I wanted to modernize it slightly but still keep most of the sounds fairly similar to the original.

Polysix on the road to recovery
Don't underestimate the power of battery acid!
So, Christmas and New Year vacation is over. But, the day before I had to go back to work I made a last effort to get something done since I'd spent most of my vacation just playing computer games or doing nothing. I'd gotten the Poly 61 keys working and felt like the Polysix needed attention, so...

Poly 61 is "almost" working now
Dead keys
Normally you'd expect an old synthesizer to have problems, for example scratchy pots, dead voices, leaking batteries and dead keys.
Well, the Poly 61 was completely silent when I got it. It lit up and I could edit the presets and store them and everything, but there was just no sound anywhere. Also, I saw the leaking battery.
I was expecting a lot of hopeless searching for errors but I was pleasantly surprised...
