anybody programming for the Launch Pad?

[Tone Deft]

how's it going? what have you found?

I've been using mode 1 because mode 2 didn't tickle the 'midi in' and 'midiparse' objects. problem is the mode 1 keyboard is split into 2 columns. I've been working with that, got it lined up (upside down damnit!) with a matrixctrl object.

then I go onto lighting lights. so not I find mode 2 responds to the noteout command and the buttons are laid out more sanely. which mode should I design for? it seems the midi in objects don't detect the mode buttons, so I can't build that in.

next step is to link all the parts. I'm kind of imaging a scenario where there are two step sequencers, one on the top two rows, the other on the bottom two rows. you use the buttons on the right to select which sequences are visible and change velocities and swing for each step. something like that.


FWIW this is what I have going, mode 1 lights up buttons and tickles matrixctrl (upside down, will fix that later.) mode 2 syncs to Live's shuttle controls and lights up the LEDs like a step sequencer, there's also LED color control.

should I focus more on max or the Live API? I haven't dug into the API yet.

any tips, thoughts, ideas? much appreciated.

btw I think transport is broken, it stops responding after a while. that's been ticking me off.

You can change modes through the Live API, but if you want to change to x-y mode through midi, just send the following midi:

176,0,1

From the Programmers guide:

Select the grid mapping mode

Hex version B0h, 00h, 01-02h.
Decimal version 176, 0, 1-2.

This command affects the mapping of Launchpad buttons to MIDI key codes for messages in both
directions. There are two possible mappings, selectable with the last byte of this message:

Mapping Meaning
1 X-Y layout (the default).
2 Drum rack layout.

The X-Y layout is best for writing applications that use the Launchpad as a free grid, as it is easy to
navigate a cursor around the 8x8 grid in any direction by simply adding or subtracting. The drum
rack layout is better for situations when the Launchpad must deal with musical MIDI notes: six
continuous octaves are available in this mode, and these are laid out in a regular pattern.

[Tone Deft]

thanks!

I read that earlier in the week but I just forged ahead with what was working. last night I remembered that I had neglected the programmer's guide sltogether and LOL'ed at my noobness.

what's not clear to me is how I send those numbers, can they be CC or notes? I include the "-" in the third command? I could play with max and use trial and error to figure some of this out but any tips are appreciated.

I'm going to have to redo a few things!! no matter, the coding itself is enjoyable.

[technog0d]

They are just sent as notes... You can use makenote and noteout to send them. Remember though... You can do this all through the API. That is the tutorial that I am currently working on.

Mike

[Tone Deft]

many thanks, I'll look into those.

I think I'm going to have a serious hindsight moment coming up.

[hoffman2k]

Do you have a patch you can share that shows some basic button access?
No need for comments or a tutorial. Just something less intricate than the CS sequencer would be sweet.

Is it also possible to make use of the "Rapid LED Update" (= updating two buttons with one midi message) through the Live API?

I am trying to put together the basics right now. In previous versions of M4L there were some issue with the control_surface object and crashing. I think it is fixed now. I am just starting to put together that type of info. As soon as i have the basics down, i will post a simple, illustrated patch to this forum.

Regards

I've had it working both ways, via MIDI (I spent a day porting some stuff when I first got the Launchpad, about two days before i got M4L) both w/and w/o M4L, and then with the API. The API works best so far, I'm thinking things may even get better once some people get their hands on the js stuff. Not my forte, though.

You will definitely have less conflicts using the API.

Thanks for the hint about changing the key assignment scheme... I read it from the guide early on and promptly forgot about it altogether (to the tune of spending several hours making a patch to convert everything on the fly...whatever, it was good practice)

O, by the way, one of the nice things about using the API is that the MIDI note assignments don't matter. The butters are numbered according to the API. Makes a lot more sense.

[Lo-Fi Massahkah]

Ok, guys. I'm digging into this just now.

Haven't been that active in the beta. Not at all. But I'm curious to the control surface api - can you give me some pointers on where to read up on that. I'm experimenting with user mode 1 right now - set to the x/y grid. It's working OK, but of there's someway of accessing it all through the api - I'm guessing that's better.

By the way, whats up with not letting us (me?) access the CCs from user mode 2?

Lo-Fi, It's good to see you on here. I always use your patches on my Lemur. The key to digging in a this point is to take apart the lesson on CS step sequencer. It illustrates the API usage with the Launchpad and APC40. You can get to it under the lesson section for Max For Live under lesson 14 if i remember correctly. If you need any help with M4L just contact me, with the contact button on my site listed below...

How about this? Receiving key presses from the LP. Storing in a matrixctrl and toggling between off, yellow, red, green.

Code: Select all
