This is a very cool little implementation! Reluctant as I might be to shout "Hey Thorsten! How about adding Impossible Feature X??", would it be difficult to add in the shuffle function from the SEQ? Whether added by you or by the user. Because a DIN sync clock with shuffle would rule ... It would also be nice to be able to put out 48 ppq (Korg) sync and 4 ppq (16 pulses per bar), or optionally to read clock from any of these sources or MIDI and output to any other.

Hi Gordon, thanks for dropping by. I should have included the main site's URL in my post to your blog, its http://ucapps.de/ You could possibly find a solution or at least some clues there. Check the DIN, DOUT and AIN, AOUT scanned mulitplexing boards under MIDIbox Hardware Platform in the sidebar.  You can have up to 64 (or is it 128, I forget) analog ins per Core (PIC host) board. There should be code for doing the scanning under MIOS. MIOS is all PIC assembly, with a resident bootloader so you don't have to reflash, just upload code via the MIDI/serial port. The assembly code is modularised, all available and very well annotated. There's also a C wrapper for higher level programming. Some other random ideas... a single RGB LED as a 3-way detector in the centre of a triangle (or ring?) of matched, individual R, G, and B LEDs ... an X-Y touchpad using two different colours - LEDs just above and aimed horizontally across the touch area, using a linear diffuser to spread the light evenly along each axis ... same, but using bar-graph LED arrays facing each other across the touch area, one side as emitter and the other as ... interpolating the analog values from neighbour LEDs to reduce error/increase resolution ... MIDI control surface composed entirely of bargraph LEDs, stroke the graph to drag the light bar up and down ... interpolating using components rather than code ...

Wow. I've got about 40 of those 8x8 arrays in a box somewhere. Knew I saved them for a reason

[me=DrBunsen]suddenly has a vision of a broken-down SX-64 converted into a killer portable MIDIbox rig - SEQ/SID/FM combo, keyboard converted into control surface, MIDIbox TV driving the 5" monitor... Internal amp and speakers... woo stop me now...[/me]

ART make nice gear. For 10 Euro I say go for it!

See the search box at the top of the page?

I get no result from either link, they both timed out. Tried clicking through and right-clicking to save. Debian and Firefox.

Hi, I'm in Melbourne. You might want to try getting in touch with Paul Perry. I don't have a direct number for him, but if you call Music Swap Shop in Elgin Street Carlton, they should be able to tell you how to contact him. He designs stuff like this, although I am not exactly sure that he does one-offs.

http://oatleyelectronics.com/bcorner2.html Admittedly it's a short delay time, but perhaps a few of them could be strung together - multitap?

Don't know if this will be of interest to you or not but... Magic Sine Waves Basically using a string of pulse (square) waves to simulate the harmonics of a sine wave. Sounds at first reading like it might be a more code-efficient way of generating sines than trig calculations. There are lots and lots of tutorials, guides, source code and calculators on the site, and the first sample chips he's shipping are PIC 16s. I wonder if the same principle could be applied to simulation of other wave shapes.

Your question is more software than hardware, so maybe try asking in the MIOS programming forum.

Well well well ... So there's all your opcodes. He also includes info on the registers, the DSP the sample format and how to upload your code. So presumably someone with the requisite skillz or a severe case of the hunger could do it. Still, don't see how this will do anything that any old PC with a 16 bit soundcard couldn't do just as well. Apart from being tiny.

I've just been reading some of those links, such as this one Maybe not so easy, and a pity, because that little module sounds very handy as a chipsynth device. One of the benefits of using the SID is that, coming from a general-purpose, end-user-programmable home computer, the information on how to control it is very well documented. However... So I conclude from that that it would be very difficult to program this module to play arbitrary notes, tunes, effects on demand. The only use suggested on those links is by uploading existing game tunes. Of course, feel free to go ahead and prove me wrong!

Just an idle thought, feel free to ignore or shoot down in flames: Could DACs from old soundcards be scavenged for use in the AOUT module? I'd imagine even an 8 bit soundcard would have a useful DAC onboard. Or are they too different to use?

I've got a 707 and a 606, and a gameboy. How did you get DIN sync working? Is it documented anywhere? Are you using nanoloop or your own software? Oooh a 606 and nanoloop/LSDJ, ooooh...

This is horrible!! Somebody stop this man! Maybe we should offer to send him any burnt-out SIDs we have. And he can send us the working ones before he butchers them.

The Silicon Chip MIDI Theremin is now available as a complete kit from Jaycar http://www1.jaycar.com.au/productView.asp?ID=KC5410 $159 AU = about $120 US

Multilabs ezMouse For all you mouse, touchpad, Wacom artpad, trackpad and trackball fetishists out there. Any news on Duggle's PS/2 project lately?

Or you could build the Theremax from paia.com, which has CV and gate/trig outputs, and use a MIDIbox to convert to MIDI. And you get a useable Theremin into the bargain.

Would it be possible to run the Linux JRE on a Mac under X11? (NB this only works on 10.3 and above - to run *nix apps under 10.2 where I am you need to use Fink) And re Mini pricing: you can replace the RAM and the (laptop size) HD yourself, and probably the CD drive, and beat Apple's pricing.

Thought about putting this under "Parts" but it's kind of off-topic. http://edrum.for.free.fr/modules.php?name=Forums&file=viewtopic&t=289&sid=3fb52383cc17f90e90ffeacc27b5243c Although perhaps it could be gutted and MIDIboxed.

There's a LiveCD called Bark which is preconfigured to use Jack. It's only available from the developer for now (0.6 version) - PM me if you want his email address.

Shareware Music Machine: DOS and Linux Harmony Central: DOS You could also try AGNULA: a complete GNU/Linux Audio distribution and Dyne:bolic The ultimate setup (maybe) would be a good ISA Soundblaster with one of the sequencer programs with editing support for the onboard FM synth, and a Yamaha XG daughtercard.

I've added a description of a Matrix Orbital emulator for Palm Pilot to this thread

PalmOrb looks promising. It emulates a Matrix Orbital LK204-25 20 character 4 line serial LCD. TK and Argtrak have put together a driver for this class of LCD (if I am reading this post correctly). Alternatively, a creative hacker could download the sourcecode and add support for HD44780 type LCDs, graphic LCDs etc.
