thanks everyone! Looks like you're in the right area.. while the regulator is fine on the SID module, i found out that my power supply intermittently supplies 8.5v instead of 5v!! I'm using a commodore diskdrive AC adapter which supplies both 12v and 5v.. looks like it's fried. I can't blame it, it's been through a lot all these years :D edit: andd when they tell you "no user serviceable parts inside" they mean it. The whole thing is encased in resin, well off to craigslist and ebay :D

I will give that a shot, it might be my regulator on my SID module.. however whats weird is that it'll freak out, then come back and work for hours, then freak out, then come back and work for hours.. I have a heat sink somewhere around here I can try to attach too I think

Hi all! Long time no talk.. I haven't forgotten about everything and everyone here though. I've moved to doing most my development on AVRs due to the GCC port availability. I *finally* after multiple years have finished my midibox SID. It took 2 SID chips, 3 recasings, 2 resolderings, but I finally have a unit that for the most part functions.. the SID was my first DIY synth and through making it and remaking it, it provided me the basis to go on an make a number of microcontroller-based AVR projects from scratch as well as build a x0xb0x :). Anyways, my SID does this weirdo thing. Peridically, maybe after 10 minutes use, it will sound "grounded out", and the contrast on the LCD will freak out so it appears that both lines are completely solid on the LCD. If I leave the unit on it will go away after awhile - it used to take a long time like a half hour but recently the glitches are shorter, like 20 seconds. If I turn it off and on it doesn't immediately fix it. Could this be a faulty/tempermental SID chip? I'm looking for someone to say "yup, I had that problem, faulty SID".. if no one does I know how to troubleshoot most everything else but I'd rather not have to start seperating my modules again to hunt for the problematic module. Thanks! Tom

Thanks for those references!! Time to go master that app :D

hahaha! Why didn't I think of that? My gf and I were playing with that on my mac a couple weeks ago :D Are you sure the mp3 doesn't have the speakjet though? it has a very different robot voice at the start counting down. Also: do you have a link on the syntax of that mac voice commands? I only knew the "say" commandline command.

oops! Sorry, shouldn't be trying to do this at work.. http://www.myspace.com/boysnoizemusic After listening some more I'm almost positive that a track on his album uses the speakjet, listen here: http://www.woopwoopwoop.com/boysnoize-arcade_robot.mp3 (its a promo so I don't think I'll get in trouble :) ) However I think he might also have some other way of doing a more hi-fi robot voice (like the promo voice that repeats throughout the track), possibly microsoft SAM -> bitcrusher or something similiar.

Somewhat OT: Anyone think that the speakjet's what Boys Noize uses? http://www.myspace.com/boysnoizemusic, not sure what tracks he has on his myspace (and can't check, no flash at work), but most of them feature the robot sounds. & down, for example.

Hey Michael, I'll hold onto mine for a bit.. I'll probably add a bit more to the simulator as I'm using it. Cheers, Tom

Thanks a lot AC, I'm now using the ACSync code extracted from the rest of the ACSensorizor stuff. I also got ACSim working in linux (required minor changes). Right now am I right that the wiki is the only place to get the ACSim code? I'll do a diff between my version and the version that's on there before putting it online, although I guess at least the wiki software tracks changes..

ooh! nice AC, thanks a lot! I just got the dev environment set up on my work computer and was going to start from scratch again from clockbox 1, but if you have all the sync issues dealt with that's half the battle :D

time to fix this and write some code at work :D

so wait, you're saying that each 4-pad quadrant cannot have 2 different velocities at the same time? wow.. that's rubbish! Almost scandal-worthy!

not enough :(. I have a TODO that can waste more of my time to parse than I have to devote to my projects in the first place.

If you limited yourself to 8 pots per core you could wire it up without the need for any AIN modules since J5 can be directly connected to 8 pots. I couldn't find the link to details on ucapps so someone will have to verify this for me.

Agreed that bitshifting is the best way to set your fields compared to hex constants. Looking closer, you're right. I was thinking the macro would get expanded into the code but reading the declaration closer it'll all get processed in the preprocessor and just the new hex value will be put in your code.

That's ugly and slow. Just use hex :P It's really easy! every four bits turns into one hex digit.

I've been real busy :( and am trying to do a proper job on the hardware for this device (unlike some of my previous cases). The software will be quick once the hardware is finished, at least :). As for CV, I'd need an analogue out wouldn't I? Support for it could be added but I don't necessarily know what it'd be for - my idea for the gate out was actually more like "Sync out", that you could wire it up with a transistor to trigger an audio looping pedal or anything with a tap tempo (my alesis modfx units for example, have tap tempo but no midi) to keep the non-MIDI gear in synth with the MIDI signal.

What do you need a perl programmer for stryd? I can prolly do it.

Yeah, he was. I saw them and they were awesome. I was dead beat at that point though after dancing up a storm for mstrkrft and the ed banger crew.

At Coachella there was a light sculpture that consisted of > 6000 lights that would do sequenced patterns. Here's a pic of it during the day: http://juvin.com/gallery/v/coachella/coachella2007IMG_1821.jpg.html oh! I just found a bunch of stuff on it. It was from burning man, like a lot of the coachella art. http://www.nw.com/nw/projects/brc/ Anyways, the thing was amazing. Had the drug users entranced. One kid told me he was going go to see "lsd soundsystem" which I'm pretty sure existed at the festival, if only in his mind.

I've had stuff like that with an LCD - I remember naively using superglue near LCDs and encoders, wrecked most of my control surface (thankfully it was only a CS A).

Okay so: your CC variable gives you a range of 0-127. you have a pitch range of -8 to 8 %, for a total range of 16. We're going to calculate it as a value of 0-16 (and worry about the subtraction later since it's linear). Which means you have a granularity of 8 CC values per pitch percent. Of our seven bits, this means we have: CC Message: x x x x x x x | ^ last three bits gives our fraction value. ^ first four bits gives our integer percent value. so our fractional value is (value & 0x3) our integral value is (value >> 3) You could use a lookup of char * to map the 8 values possible for the fractional part of the CC message to a character string. It would probably be cheaper than a division. ie: char * fractionstrings[] = {"0","125","250","375","500","625","750","875"} then in our lookup code, just print fractionstrings[value&0x3] for the fractional component. Any questions just reply here. edit:clarifications (I hope)

I did some work on a broken MPC2000 I owned for about a month (store sold it to me saying it worked, it actually had pins on the RAM SIMM shorted together, which I fixed.. and then noticed there was a crack down the daughterboard I had to point-to-point solder across). I wish I still had my notes, because I had sketched out most of the circuitry connected to the button sensors. IIRC the supporting circuitry was based around two amplification chips that each had two amplification channels, and would switch on columns (so one amp chip took care of the top two rows, the other chip the bottom two.) I can try to get part numbers but the computer I was doing this research on is no longer working.

Hey guys, Let me know what you think of this song my band just finished mixing. It's a cover, we're about to send it to the band who made the original, and I'd like a third party opinion if there's anything blatently problematic. http://www.woopwoopwoop.com/music/die-good.mp3 The original band is http://www.myspace.com/diemannequin Cheers, Tom

The second option would be faster.
