after many years away from MAX I am back! Yay. Unfortunately somethings I am finding very hard and hopefully you can help.

how do I thin a stream of data so that numbers do not repeat sequentially? For example when using [scale 0. 1. 0 127] to thin OSC controllers I get a lot of the same int over and over such as 22 22 22 23 23 23. I want to thin this so it would only be 22 23. I am mostly controlling MIDI gear and I don't want to mess up timing by sending the same controller value over and over.

when using TouchOSC to control a piece of MIDI hardware (Eventide H7600) I am getting feedback as the Eventide sends its on screen values out as CCs when they are changed. Or maybeTouchOSC forwards its input to its output? This I am very confused about. Somewhere I have feedback between TouchOSC, MAX and the H7600. Are there any example patches that show how to deal with MIDI devices that feed back? I notice a bunch of gates in the TouchOSC examples that might be for this but they don't seem to have any control other than on screen toggle boxes.

issue 1: use [change] (or [zl change] for lists

issue 2: I'm not familiar with your system, but when you solve issue 1 this might be solved as well.

I used TouchOSC directly to my Max patch, with visual updating from Max back to TouchOSC, no feedback---apparently it only sent the data when the iPhone screen itself was tapped. Not sure if this has changed though. And yes, I don't think the gates/toggles in TouchOSC are for this, they're just general-purpose toggles.

When your Eventide sends out the CC values, is it sending back into your patch? And then these are sent to TouchOSC? If so, you'd just need a "set $1" or [prepend set] before they go to TouchOSC, this way you can see the current values, but they won't activate the feedback loop.

thanks for your help, [change] was the missing piece. After a little sleep things made a lot more sense and I adjusted my routing to prevent feedback.

I am very glad to be back into MAX - feels very fulfilling to be able to make custom music tools without spending more money on my modular :)
