super tempted to move that to top priority (aside from saving up for nautilus batches a few months)

hhhnnnnngggggg

it's been so long since I've built a noise/drone box that wasn't just a couple simple oscillators.

I'm thinking a box with several oscillator "pairs", each pair arranged in narrow vertical rows, like a tiny modular synth. each pair with two oscillators (with different shapes) + mix knobs + toggles that allow you to modulate one osc with the other. fm, rm and just blend. each pair with its own resonant filter, too. all pairs mixed down with their own panning and volume, so the final output is stereo too. I'm thinking 4-5 pairs (so 8-10 oscs total).

I want some kind of master modulation on pair vol/pan, too, maybe. like slow swells and pans on each. ambient drone heaven.

ugh, so many knobs. 10 knobs and 1 toggle per pair. knobocalypse

technically, I'm thinking I could have one 32bit pic do 4 oscillators (so, 2 pairs) along with all the modulation and shapes and stuff

thanks! it's pretty fun to play.

I think I'm gonna switch from pic32 to stm32 arm, though. I've been having a lot of trouble interfacing with codecs with the pic, only the slower 40-50mhz ones have I2S. arm m4 has all that in spades, plus better adcs, easier dram interfacing, plus better lots of things. we'll see

Ya actually i started to work a bit with stm32 as well. I just went to a sort of promo thing from st at a hotel by orange julep the other week. It was pretty funny. I think there are already 100 MHz and about to be 200 MHz pic32s though with i2s and probably more competitive features. Check the microchip website.

I had some problems with the pic32 and pps crossbar for i2s function as well on certain pins. i can get it to work no problem with several different codecs, but it seems some pins that are supposed to work according to the datasheet actually do not (although actually just using spi is ok?). I contacted microchip but they said they could not check since the dev boards they had on hand did not connect teh codec to the pins i used (it was with 32mx150/250 etc). thanks guys!

I did see the thing about the 200mhz pic32s. it's great that pic are catching up, but at the same time when they do come out, we'll have to wait for support and software to catch up as well. on the other hand with stm32, we already have a lot of mature tools. so there's that.

yeah boards like that are annoying. I just make my own dev board if I know I'm gonna be playing around with a certain chip for a while.



some of the traces are probably too long for 100% reliability, I know that now. another problem.

anyways, I just got a little arm board, the stm32f4 discovery board which is pretty cheap and has a lot of pins. played around with coocox ide for a bit. I like the interface a lot, but the lack of simple examples is pretty extreme. I'm not all that good at 32bit micros, so I'm looking for a simple timer interrupt example, and I come accross a 3300-line one that shows off a whole bunch of other stuff. a lot of the others are like that, not super practical when you're trying to learn. we'll see. I might just stick with mikroc for arm, I was already using it for pic32, except they don't have i2s libraries and they're not free. we'll see.

what arm ide you using?

nautilus rev 5 is mostly ready! unfortunately december is an expensive month with all the travel and stuff, so I'll only be able to start ordering everything in january

i just use coocox as well. It seems to be the best free offering? I am certainly not an expert on all of what is available. Even at the ST info session they mentioned it, although they had a list of like 20 something ide's haha. I like coocox cause i am a bit familiar with eclipse and CCS (also based on eclipse) so... I also tried IAR EWARM, this is not even close to free unless you have code size limit or time limit, but it also seems solid.

that's a good looking layout!

Coocox itself looks solid, I'm just bitter at the lack of clear examples and relative complexity of the libraries, compared to mikroC for instance. I may be reading it wrong.

I might stick with pic32 for just a while longer, since I already know how to use it. If I can finally get the codec working, I might stick with it.

Which codec(s) were you using back when you were using pic32?

rounded corners FTW!

so who bought the programmable tremolo etc one on ebay over the weekend?

I didn't buy that one, but I have an older Hollow Earth. Awesome stuff.

it was hard not to pull the trigger.

The $450 v1 that's been up there (on and off) for a year? Good grief that was expensive.

$550 this go around, if its the same one. white graphics with octopus like awesome on it

Nope, it's back up. $585 BIN. That's just absurdly high.

Dude's never gonna sell it if he keeps hiking the price up every month like that.

It's been the same one on there for over a year, serial #005. Price just keeps going up.... and up....

I was just about to post that. you beat me to it
