smd, no arduino... ok, maybe not my cup of tea then

imho there should be a lot of space, but i can relate to your plans to have things done as SMD. if i could solder SMD i would also use it all the time, for now it remains a mystery to me. especially i cannot understand what there is to like about it, unless you want to build a laptop ;)

Try it.  I find it easier, faster, cheaper than through hole not to mention there are 100x more parts available.  All you need is a fine tip, some solder flux, and tweezers.  I have no idea why people have such an aversion to SMD, there is no magic to it and anyone who says you need an oven, masks, etc has never tried it themselves.  There are only a couple types of parts that have to be soldered in an oven (BGA for instance), everything else can be done by hand.  Hell, we do 0402 parts by hand under a microscope at work for prototypes.   Everyone seems terrified of it until they try it then it's "oh, why haven't I done this before"

so here's my board with the board to board jumpers installed

So I have a new midi interface ready with kind support from Pete @ Midisizer:

Specs:
6 x trigger outputs, positive or negative going pulses (polarity configurable per trigger) with width 1 to 5 or 10ms
6 x trigger switches, momentary short to ground
8 level common accent output driven by note velocity
Learn switch: channel, trigger notes, reset to defaults after 10 secs
MIDI IN and MIDI THRU ports
2 x LEDs (MIDI IN, Triggers)
Persistent settings with auto save
Firmware update via sysex

Based on a ATmega328 with a bare minimum of parts (12 to be precise).  I have it on bread board now and will be testing this weekend.  After that, back to work on the CS board!

Is that a custom thing,  a thing you can buy, or is it a DIY thing on the net somewhere?
i am not paid to listen to this drivel, you are a terminal fool

Altitude

custom but I'll get his blessing and release it here..

Altitude

So the prototype midi interface is built on breadboard and works perfectly.  Very slick and simple to use, the learn function in particular is great, you simply hit the learn button and press 6 keys that you want to trigger the voices, that's it.

I has some debugging to do on my voice board (no noise, HH, and tone seems broken since it only increases background noise)

This would be awesome !
Do you still intend to release your midi interface someday ?

Altitude

Yeah, someday.  Midi interface is done and tested but other projects have my attention right now
