awwwwwww much 2 late....

Project selected: none of the above.

I'm going to be working on a research project with my school's IEEE chapter.  We're going to be connecting an accelerometer to a glove and an Arduino, the Arduino will pass accelerometer measurements to a computer running Pure Data (the free, open-source equivalent of Max), and Pure Data will then perform musical commands in response.  For instance, a bongo beat motion with your hand will generate a drum strike sound, its volume dependent on the strength of the air slap.

You can get the acrylic cases from Chris via emailing him (PM me for his address). He cuts to order. Really nice guy!

The only thing i can see what would be a little tricky to get would be the pushbuttons. but i think even those might be obtainable via Mouser/Digikey. i haven't looked up the manufacturer.

The 1 thing i would change on his design is the PSU circuit and connector. Other then that it's a great little sequencer! Paul did a great job.
I dont see much more reason to modify this. everything is on his website for users to build them DIY style.

SO perhaps moving on to a different project is in order. Let us chat in private on some ideas.. perhaps we can do some joint efforts.

MIDI/sync solution for the NES - NTRQ needs it! NEEEEEEDS.....

(ok a bit selfish but I get enough people asking me so it's definitely a wanted item....)

I don't know if you'd be interested in this sort of thing, but I know there is a lot of interest around MIDI solutions for LGPT on the Dingoo and PSP handhelds.

The SEGA Master System is also compatible with the YM2413 - Tim Worthington aka Viletim makes repro boards that support the YM2413 for the SMS.

Those YM series chips are in lots of things from old keyboards to arcade cabinets. I found a Ym2163 in a couple of old noname keyboards.  Datasheets for ym2149 and ym2151 are available from datasheetarchive.com .

Okay, I figured it out.  The sound I'm looking for comes from these chips Yamaha built that found their way into Sega consoles, handhelds, and arcade games: FM synthesizer chips.  Unfortunately, nobody seems to be making anymore.  Anybody seen some modern-day equivalents?

Now that I know someone else has already done work with that chip, and after hearing it, I'm not quite as excited as I was.  I was, and still am, looking for a particular sound.  I think I'm going to go with the Gorf.  At the very least, I'll have a small sequencer to test ArduinoBoys with.

EDIT: or I could try writing music again.  Maybe start with a cover of Fleetwood Mac's "Peacekeeper" or James Taylor's "Your Smiling Face".

Yeh the SN76477N looks really interesting, Theta_Frost!

Beat me to it!

The Gorf would be really cool!  I'd be game for a chip synth as long as it doesn't already have a MIDI implementation which little-scale has made one for the SMS - another chip would be really cool though.  Perhaps the same SN as in the SN voice?

The third option sounds very similar to this: http://little-scale.blogspot.com/2008/0 … aster.html

Also, I've got a standalone version that I haven't posted about, which is pretty much equivalent to my SEGA Master System interface without the SEGA console itself.

The third option sounds great!
