How to generate values from dragging on a matrixctrl?

Apr 28 2014 | 7:08 pm

Is it possible to drag on a connection in a matrixctrl to produce more than just 0 and 1? In particular, is there a way to have a dial on each connection to control the gain of that connection or do I have to implement those dials separately from the matrixctrl and overlay?

if in max6, see helpfile for matrixctrl under the ‘dialmode’ tab…
if in max5, see reference doc for matrixctrl under the listing for ‘dialmode’

it’s all there in the docs already ;D

Now I understand your username (grin)

I already experimented with dialmode, which according to the docs is a toggle. When I set it to 1 I could then drag between the discrete values 0 and 1.
However I am trying to use non-binary mode to control the gain at each connection so need to generate continuous values between 0.0 and 1.0, if I’m understanding matrix~ correctly.

Clearly I could do this by creating a matrix of my own dials and have them generate the appropriate 3-value lists but I thought that functionality was built in.

"When I set it to 1 I could then drag between the discrete values 0 and 1."

with your own pic, you can do more(i can definitely get floating point values between 0 and 1 and dialmode is great for the non-binary mode of matrix~)… plus… i was only trying to help given the very basic phrasing in the OP :D

"i already experimented…"
most likely not enough ;)
(haha, no offense, though! you said now you understand my username so i figured i can now take a little more license over it ;D)

Yeah, I did notice I could put higher values in but it was screwing up the image and I realized I’d have to create all new images.

Ultimately, I decided it would be easier to throw out the matrixctrl object and just put together a rectangle of dials to generate the row/col values as well as the gain. That had the extra benefit that I was able to transpose the coordinate system so that the rows are outputs and the cols are inputs —- similar to how the old EMS Putney matrix system worked.

I have it working quite nicely now but I really appreciate the feedback from everyone (and no, I don’t take offense easily :-)

I’ve been banging on about how great dial mode is for years – search my posts for the same example repeated ad nauseam, which includes some graphics you can use.
Or just see the attached,

Thanks — I had found earlier references but had found that many attachments were missing so it was hard to actually figure out what others had done.

nice! glad to hear you got it the way you need(and these days… i, myself, am trying not to freak-out/offend anyone specifically… only the entire forums, in a general but harmless way :D)

just wanted to add… and it may be very tangential or unuseful, but awhile back, i found an easy way to create pics for matrixctrl’s dialmode is to use javascript to automate photoshop.
here’s an example .jsx file in case it helps as a starter for anyone else(you probably don’t want to double-click the file if you have photoshop on your machine, it will then automate opening up photoshop and creating a 50+ layered dial image(which is also not very pretty looking)… and i don’t think the output .pct format works anymore in max6… but anyhoooo… there it is, in case it helps :)
please ignore this post if it doesn’t make sense(i haven’t looked at it in years, could not explain what i did and much of it is just borrowed blocks of code…).

Edit: no wait, i’m lost… that was probably for pictctrl, but the general ideas are similar :p
