some work at the software end, stage 1

[ashlevski]

hi, I've finally found a bit of time to start work on software to do
stuff with the octomod.

Greg: I only just properly read your post about sending MIDI
controllers 0-7 to the new P5_Octomod software - I'll have a look at
that tomorrow.

a) starting with a Max patcher - a bit like the PD patch - it really
just tests the octo & the app.

I'll try & improve this & compile it as a standalone app - something I
realised I haven't ever really done before. I'll post an URL where it
can be got from.

I had questions about how the '/dac' OSC messages work but I think it
comes down to me rediscovering MIDI & OSC as a far as encapsulating &
sending data. Bit out of touch.

the following isn't much use unless you own the full version of Max.

Looks cool, but when I open the Max patcher, there are only GUI
elements, no logic or connections. Is that how it's supposed to be?

I like the idea of opening the host app automatically, that's smart.

I would suggest that you not implement MIDI on CC 0 - 7 right now,
because that's going to change shortly.

Anyway, looking forward to seeing more.

Here's the Max code that I normally use.

hah, I'm so old-skool (not necessarily in a good way) in max: I used
pack->bondo, yeah pak, pak

Yeah that patch should open in 'presentation mode' so it would only
show the UI items. I actually added the MIDI stuff (cc 0-7) late last
night - here's a tester that does both OSC & MIDI:

http://catfingers.net/files/octotest-02.app.zip - this should run ok
without needing Max of any sort &
http://catfingers.net/files/octotest_02.maxpat.zip - this is just the
patch - so you can open it & see what's going on.

Drag inside the multislider to directly change the channels & also to
prove that MIDI is working!

the patch needs the aka.shell external - available from:
http://www.iamas.ac.jp/~aka/max/download/aka.shell.zip

I -could- try & cut a Max Windows standalone if anyone is interested
(I think there's a shell external for XP). I own a copy of Live & M4L
so I can spin out versions for that, on OSX - I think things may get
weird x-platform in Ableton.

- I'll keep modifying & re-burn as an app as you change things in
USB_Octomod_P5. This whole thing was to open up how this could all
work when joined to sequencing/event-generating app.

The next step might be to work on something that maps MIDI to OSC in a
more configurable (& maybe presettable) way, though you (Greg) might
be working on something similar for the Octomod app.

One question - do you have any recipe on good values (level, duration)
to best generate a trigger or gate out of one of the CV outputs?

Looks good. My preference re: MIDI is to leave it very generic - that way users can create whatever specific interface they like. I don't use MIDI often (much prefer OSC), and I wouldn't presume to have a single best way of doing it.
