Orac 2.0 with MPE support!

thetechnobear · April 13, 2019, 6:22pm

its looking for the modules subdirectory (which is there), directly below where its being run from.

its also looking for orac.json, from which it finds the data directory for presets
(/root/data/orac -> presets/Init/params.json)

(the presets are copied to the right place in the post install step)

(Ive noticed the media directory is wrong, in orac.json, it should be /root/media, but thats only affects samples, and your not at that stage yet )

can you do the following and pipe output to a file, and then share it somewhere

export BBB_ADDRESS=localhost;~/Bela/scripts/run_project.sh orac

you should see something like

root@salt:~# export BBB_ADDRESS=localhost;~/Bela/scripts/run_project.sh orac
Checking the board is up and running at localhost...done

that is the output:
http://fstrixner.de/files/Orac/orac.log

The order is a little different, this part is not at the bottom for me, but before the mainDir: section:
loading settings : rack
preset loaded : Init
preset loaded : Init

Will in the meantime set up Orac on my Pi2, perhaps, if this works, I can find out the difference.

thetechnobear · April 13, 2019, 6:35pm

ok, so orac is fine…

but for some reason MEC is not connected to Orac. (I assume you had orac running)

I can see here, if I start MEC, but not orac - I get exactly what you have in your video.
basically MEC is processing the UI, but has no ‘rack’ to give you details for.

NothanUmber · April 13, 2019, 6:37pm

On first sight Orac seems to be running:
root@bela:~# ps -ae | grep -Ei “mec|orac”
498 ? 00:00:10 mec-app
5289 pts/1 00:00:40 orac

And at least some communication seems to be happening(?):
root@bela:~# netstat -atunp |grep -Ei “mec|orac”
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 5289/orac

thetechnobear · April 13, 2019, 6:49pm

ok, Im noticing for some reason bela is being really slow/difficult about updating itself if mec starts after orac… its doesn’t appear to get getting the meta data as it should…
(it doesn’t matter on other platforms which starts first, as they negotiate at startup)

try the following… start mec first ie.

systemctl stop mec
make sure orac is stopped

systemctl start mec
connect pd client (this doesnt really matter)
export BBB_ADDRESS=localhost;~/Bela/scripts/run_project.sh orac

for me this works, and is what I have generally have been doing - as mec is enabled on startup,
and then i run the orac project.

NothanUmber · April 13, 2019, 6:58pm

That worked! Well at least it seemed it did, don’t see too many modules, tried to load midiout and got this with orac (segfault is reproducible when choosing the midiout module):
Parameter Dump : Clock : utility/clock

pg_main
Main
int [S],c_bpm [S],BPM [S], 10.000000 [F], 480.000000 [F], 120.000000 [F],
bool [S],c_midiout [S],Midi Out [S], 0.000000 [F],

Segmentation fault

This is the list of modules I can choose from:

utility:
arper
chordroll
clock

midiout
note_cvin
noterepeat

thetechnobear · April 13, 2019, 7:07pm

yeah, Ive been testing here… for some reason on bela mec is not getting sync’d properly if it starts after orac… I’ll investigate, but its probably bela dropping udp packages because ‘its too busy’.

(honestly, Im getting a bit tired of bela/salt - its a great thing when it works, but its just seems to be quite unstable when you start really pushing it!)

yeah, error looks like libpd is crashing due to some kind of midi output issue (again fine on other platforms) … I’ll have to check perhaps the bela rendered is not probably doing midiouput…
(perhaps you can see why I getting fed up with bela )

anyway other modules are fine.

no there are loads of other modules
you are just in the ‘utility’ category…, carry on up, and you’ll see “…”
click on this to go up a level, then you can into into synths etc.

thetechnobear · April 13, 2019, 7:10pm

a good first test, since it doesn’t require midi … (*)
load “seq/euclid” into a1, set note # to 1
load “synth/basicmono” into a2…
and you should get sound out

(*) Ive not played with midi setup on bela for quite a while - I assume its working still with a single midi device.

NothanUmber · April 13, 2019, 7:10pm

Ah, stupid, have to scroll up when utility is shown… yeah, lots of modules - great!
Regarding Bela: Sub 1ms latency is of course great, but if it doesn’t transfer to Orac anyways then this won’t help. Will set up the Pi2 (Pi3B+ with pisound arriving soonish), probably a better fit then.

NothanUmber · April 13, 2019, 7:12pm

No sound from euklid:

loadmodule: loading sequence/euclid into a1
error: receive~ outR-a1: no matching send
error: receive~ outL-a1: no matching send
error: receive~ outR-a1: no matching send
error: receive~ outL-a1: no matching send
error: receive~ outR-a1: no matching send
error: receive~ outL-a1: no matching send

thetechnobear · April 13, 2019, 7:13pm

no euclid, is just a sequencer … you need to put a synth into the slot following it (a2)

(the errors aren’t ‘real’ errors, they are just pd complaining, when I re-patch so temporarily remove its outputs )

yeah, read this about ‘bela performance’ (https://forum.bela.io/d/545-bela-performance/32) and you’ll see why I was kind of disappointed…
basic upshot is, sure if you code in C++ specifically for bela, you might be ok - but use higher level tools (pure data, super collider) and its very likely you’re not get it…

NothanUmber · April 13, 2019, 7:15pm

still no sound (euklid is on a1, basicmono on a2):
loadmodule: loading synth/basicmono into a2
error: receive~ outR-a2: no matching send
error: receive~ outL-a2: no matching send
error: receive~ outR-a2: no matching send
error: receive~ outL-a2: no matching send
error: receive~ outR-a2: no matching send
error: receive~ outL-a2: no matching send

Ah, getting sound, must change notes from 0 to e.g. 4
Works, great! Thanks a lot!

thetechnobear · April 13, 2019, 7:16pm

you told euclid to play some notes ?

NothanUmber · April 13, 2019, 7:17pm

yes, the problem sat in front of the monitor…
Great, play time!

thetechnobear · April 13, 2019, 7:21pm

yeah - I probably should caveat what I said…
if you keep the load ‘reasonable’ it does work - its not that its useless, just I was disappointed.

anyway have fun, sorry took so much fiddling around.
let me know how you get on with midi if you try it

btw: if you want the samples to work, you’ll need to change orac.json to

{
	"dataDir":	"/root/data/orac",
	"mediaDir":	"/root/media",
	"userModuleDir":"/root/media/orac/submodules"
}

NothanUmber · April 13, 2019, 7:24pm

Sure, will give MIDI a try! If it works fine with Bela then I’m happy because this would be a great use for this box. The neat thing is that it can be bus powered, so Bela in combination with Onde could be a perfect combination!
Thanks so much for your great work, a lot to explore here!

NothanUmber · April 13, 2019, 7:41pm

Yay, the Linnstrument can be bus-powered by the Bela when bus powering the Bela from the PC. Onde standalone setup here I come!
MIDI is working out of the box - at least for the basic mono synth (it crackles a little bit, even if I forward the outputs of orac to /dev/null).
Basic Poly only crackles with higher or lower frequency based on note, no real pitch detectable.
And it seems to totally stress out MEC, you can watch the individual menu entries update one line per two seconds

A naive plug Pico in and play attempt didn’t work yet, Pico is probably not configured in MEC by default (should be able to get this going on my own).

bengersfood · April 13, 2019, 7:43pm

I’ve installed Orac 2.0 in my Organelle and the new MEC app and am now unable to get my Pico to speak to the Organelle. I run MEC and then launch Orac set to midi 0.

Is there some stage that I am missing out?

NothanUmber · April 13, 2019, 7:46pm

At least for Bela Pico isn’t configured in MEC by default. Have a look e.g. here how a pico enabled config would look like:

github.com

TheTechnobear/MEC/blob/dev/resources/picoosc.json

{
    "mec"  :  {
        "eigenharp" : {
            "steal voices" : true,
            "voices" : 4,
            "velocity count" : 5,
            "pitchbend range" : 2.0,
            "firmware dir" : "./resources/",
            "throttle" : 1,
            "mapping" : { 
                "pico" : {
                    "_notes" : [ 2 , 5, 12],
                    "calculated" : {
                        "keys in col"    : 9,
                        "row multiplier" : 1,  
                        "col multipler"  : 5,
                        "note offset"    : 48
                    }
                },
                "tau" : {

This file has been truncated. show original

Think you would have to add this to ~/MEC/osckontrol.json
Experimenting with that on Bela, let’s see…

NothanUmber · April 13, 2019, 7:53pm

At least on Bela the Pico adventure ended soonish. Pico firmware isn’t part of the default release it seems, so we have to copy stuff over from git.
