OpenTZT and MIDI/DM2

[tdeagan]

I'd like to start a seperate thread, that will move to SourceForge when ready, to brainstorm how to map the DM2 to the OpenTZT GUI via MIDI. Yes, of course, general MIDI support is essential, all MIDI surfaces should be supported, etc., etc. And whoever has interest can pursue those ;)

The low-cost esthetic of the DM2 makes (in the fantasy world of my mind :dali: ) a perfect fit for the Free esthetic of OpenTZT. It _seems_an obvious initial target (a boy can dream...)

So, I'm very interested in how people think the DM2 should be mapped to TZT (which may lead to development tasks if the target functions aren't MIDI enabled.)

Of course the mapping may be different in different 'modes', but just copy the set for each mode you want to describe.

Here are the results of the code search for TZT MIDI functionality:

Just to help know what are the intial feasible targets for DM2 mapping.

I just got my DM2 working in resolume... good stuff, but the fun ends in 12 days, but I will put some thought into how it might work as a TZT control surface...
the 16 ring buttons translates pretty well into the 18 avail. clips per F#....
the 1 2 3 buttons above the joystick could advance up and down in the F# with 3 being uh... CNTRL? hmm... maybe the bottom left hand 1 2 3 4 buttons could be the CNTRL and SHIFT buttons.... I'll have to give it more thought... at first I wanna say there aren't enough buttons.. but I'm sure someone will amaze me with something I hadn't thought of... good luck guys... I look forward to hearing more on this thread...

..james...

PS... the joystick could control the F# selection in the 2D way that has been mentioned (F10 not taking you back to the F1 of the new bank)

PPS. I'm still not sure what all the DM2 to MIDI sw is cabable of... looks quite thorough tho <tips his invisible hat to pDoom>

PP?S I'm going to remove the springs from the joystick, at least from one axis... its annoying on both...

thread!! I got the DM2 to work with TZT!

did you get the DM2 working by setting up the DM2>MIDI software or.... ?
while comprehensive, the DM2 s/w can be a bit imposing at times as I know just enough about MIDI to get myself in trouble ;)

[tdeagan]

Yes, using a DM2->DM2MIDI->MIDIOX chain as documented at pdoom.ch (cause he wrote the fantastic DM2MIDI software) I then did a couplafew wierdities (soon to be well documented) with the OpenTZT config and it works!!

I'm planning on spending a bunch of time this weekend building a decent dm2 config (it's trickier than I though it would be since I have to use scads of 'multiple event' chains all tied together, but the capabilities of the DM2MIDI software have blown me away in their ability to support software that it never knew about when it was written.)

I'm updating the TZT MIDI config info in the other thread.

Frighten me...

so its like as long as the control ring is spinning CW it will send MIDI data (thro dm2>midiox) which would represent say... running your finger down the # keys in one of the /_/ or /\ or the other (forget what it is right now) patterns...
hmm... like macros yes?

<time passes>

<mind hurting from pseudo code>
I'm not a coder, but I think I get it...... sorta

Pretty much. I'm working up an advanced dm2 config, it's challenging due to the limited number of (currently) modifiable params.

Here's what I've got so far:

scratch ring left == L_CTRL+NUM
scratch ring right == R_CTRL+NUM
XFader == clip speed -1X to 1X
left lock button == clip speed BEAT-4X
right lock button == clip speed BEAT 4X
Button A == use top bank
Button B == use bottom bank
bottom left Buttons 1-4 == restore memory locations JKL;
top center Buttons 1-3 == select player 1-3
Solo button == HOME key (set BPM by tapping)
Y axis of joystick == whole clip effect value

I'm struggling with what to do with the 8 buttons on each wheel. Picking clips or effects from the library isn't (currently) available.

I'll post the dm2 config file as soon as it's settled at http://wysiwygvideo.cmo/opentzt.html

It's already EXTREMELY cool!
