I'm using PD 0.46.2, and just using an array to make a basic sequencer.

I'm just having issues limiting the functionality of the array. I just want it to output 0, 1 or 2 on the x axis. In properties, I have my Y range set from 0 to 72 (for 72 steps), and I have my x range set from 0 to 2.

However, when I click with a mouse to set the point, I can drag them up higher than 2, and they report a number higher than 2. What am I doing wrong? I thought that would have limited the functionality.

Also, is it possible to limit the output to whole numbers, and not decimal numbers? Or do I have to scale the output into who numbers? In max/msp I'd use something like [scale], is there an equivalent?

@toddak Its an extreemly ugly hack........... but might work for you......

or you could tap them in by hand, which might be easier.......

Hey again David, in a similar time zone at the moment so less delay in message

So, the loadbang message box looks like it will solve the formatting issues for the actual graph, many thanks!

But in terms of limiting the input, or output, to whole numbers, there's obviously no straight forward solution then? The hand system looks pretty great, its either that or I switch to list at this stage!

@toddak Not for mouse input I think. The mouse is sending points on the screen to the graph. You would probably have to set your graphics card to 2x72.
Even stretching out the graph horizontally (second screenshot) it was not easy to accurately change the values (at the correct x position).
If you want to tap along to a recorded piece (rather than input as a "step sequencer" as in the hand input above), you could maybe assign keyboard (midi or computer) keys to the requires values, and have the array scanned slowly with a metronome beat to keep you in sync......
...... getting carried away!

Yes, maybe getting carried away!

I did try the tap entry approach, but have in the end decided to go with the a text file instead. Its a little more accurate, and a little easier to see visually.

However, the other messages didn't really seem to work. Frustratingly, the array will still extend beyond the bounds of the graph, and generate numbers higher than the scale.

@toddak Yes, you still need to filter and constrain your list messages prior to putting them into the graph. The bounds and scale and setsize, resize etc. messages will set / reset the graph. Normalize will reset the y points of the graph, but scale all the points...... which is not what you want.

OK ....... so it's ugly hack week........

maybe i'm not understanding the question correctly
