Yamaha CS-40m

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).

Behringer UMX49

This keyboard also deserves to be mentioned!
It is my MIDI controller keyboard that I've been using the last three years or so.

Behringer Xenyx 1204USB

As described in the Xenyx 1002 post, I needed to be able to rout a single audio channel to the audio input of my Terratec Phase 22. I needed the smallest mixer with sub outs or alt outs that I could find. The Xenyx 1204USB seemed to be that one.

Behringer Xenyx 1002

I guess I should include this one in my equipment list.
I bought it new about two years ago I think and I've had it sitting on top of my PC tower case.

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"...

Started building

It always feels good to get started with the actual construction!
Here's just a photo of the two boards with the buttons and almost all of the LEDs.
