I haven't found the chip to be particularly unstable. Maybe it gets stuck once or twice, though it seems to respond to the next bit of hand-waving.

Hi Sparx, I picked up the sock-puppet meme from audiocommander's web-site: he mentions it as a paradigm for single-handed operation. A white sock gives maximum reflectivity for the IR sensors. I think we'll work on singing, rather than speech first. How's your speech synth coming along? Regards, Chris.

Many thanks audiocommander! I've done quite few electronic projects over the years, but this was a real challenge (and it takes so long!). I'm keen to get it cased up. I was going to make something with lots of ply trendy slices (see attachment), but I'm wondering if I should try for something a bit more Luigi Colani (loved his stuff when I was a kid and saw his exhibition in London a few years ago). Next steps will probably be to check it out with some MIDI running in.

Testing, testing... my K2 works! I got it working about six months ago, and in the lull of a new year, thought it would be good to share. Hope all the link stuf works right. Anyway, more work to do, but very satisfied to have got this far. Maybe I should post this on the projects page, but it felt like closure for this thread. If only I could get the video to embed properly Regards, Chris.

Hi Audiocommander, I'd appreciate some advice on configuring the sensor matrix. Question 1 When I built the sensor matrix, the order in which I connected the sensors was arbitrary, because I was using the sensors to drive a Max patch. Now I'm using it to drive the KII application, they need to map in the correct order to the AINs. I am using AINs 0-3 (J5a on SmashTVs R4 board) which certainly gets results, so I assume that's the correct set of inputs. One of your earlier posts shows the following diagram. BEAM1 BEAM2 \ + + / \ / \ / \/ \/ /\ /\ / \ / \ / + + \ BEAM3 BEAM4 Do the beam numbers map beam 1->AIN0, beam 2->AIN1 ... beam 4->AIN3 ? I have looked through the code, but it is not clear to me. Question 2 What's your intention with how the beams work? Should the top two beams converge above, below or at the same level of the lower sensors? Regards, Chris.

Thank you! I enabled midi merge by changing disable to enable in main.c , which seems to work and sends midi inputs to midi out, but not data from the sensor matrix: you can see sensor matrix changes happening in MIOS studio's midi input pane, but it's not transmitted to the output pane - however, MIOS studio keyboard values are transmitted to the output pane. Regards, Chris.

Don't know how, don't know why, but v0.2 now compiles. Perhaps because I closed the Notepad++? Anyway, it all works and I am very pleased. :w00t: Modifying the code to use a 2x16 LCD and read the AINs for the sensor matrix were both trivially simple due to clear, readable code and good commenting. It takes me back to Spitalfields four years ago. All credit to Audiocommander's excellent design, coding and documentation. Not to mention the midibox infrastructure and the prodigious amount of work that's gone into the whole body of knowledge. Naturally, there's still some mopping up: Sort out the configuration of the sensors to get the tongue movement associated with the correct sensor postions Make nice frames and cases to match others Investigate additonal options for routing the controller to send cc or NRPN signals out to a synth Investigate the MIDI syncing and note following Time for a celebratory beer. And thank you very much to Audiocommander for sharing your great project.

OK. I'm 5'8" short greying hair, beard, may be wearing a suit or smart casual depending on work situation. Will almost certainly have an assymetric black rucksack (single strap)

After a long weekend away, I took a fresh look at the circuit diagram and put in the power LED (it's not optional) and (ahem) :blush: put in the J2 jumpers. I now have sound, and I can trigger allophones from MIOS studio. Hurrah!

Hi a|x, Thank you for asking. So far: v0.1 compiled and loaded (.hex and .syx) into PIC 18F and 16... this morning. It kinda works but no sound. I can get the values characters on the LCD to follow MIOS studio and indeed Max patches for basic MIDI note numbers and the LCD tracks the note names, and the harmonizer listen function on cc37 changes betweeen * and - :I haven't tried any other cc values yet. So I'm reasonably confident about the Core PCB soldering and the code compiling. I'll probably build a Max interface to replicate the MIDI scheme for more testing. The Speakjet board works fine under Phraselator, as far as I can tell. I haven't tried anything too sophisticated, like sentences, but have put in new words and so forth, with good results. This board is powered by the IIC connection, and I have checked the connections pin to pin on my IIC connection. It always says 'ready' when powered up, occasionally with an extra bonus sound. So, my plan is to get sound out with v0.1, then figure out how to get v0.2 to compile. Regards, Chris.

Excellent. It's in the diary. Any thoughts on venue! I'd always advocate De Hems or the Pillars of Hercules in Soho, but am happy to be introduced to new venues. Friday night is busy, so we'll need some way of picking each other out. Carnations?

I'd appreciate a confirmation that this message got through because whenever I click on the personal communication notification, I get an error message saying I'm not allowed to use the personal communication.
Best, Chris

The v0.1 application seems to compile OK. There's mention of some fstack error as it does so, but it finishes the process and produces a new hex and syx file, amongst other things. Interesting.

Hi a|x, I would love to join you both for a beer in town, but will be in Romsey, Hampshire for the Beggar's Fair that evening. Maybe another day? The 15th is good for me, otherwise other weekday evenings are also good till the 23rd. I'm around for the first two weeks of August as well.
Regards, Chris.
