Max servo control robot drummer

Do you mean solenoids (on/off) or servos (position data)?
From the patch it looks like you're randomly setting one 4 servo positions each 1.5seconds.

So it's possible that each servo might not move for a long time.

Either way, I would probably break out each servo into its own data path, so its easier to read the state if nothing else.

Perhaps this helps (it kind of does what I think you want, with control over the probability of each additional servo changing).

Thanks Rodrigo,

I will take a look at what you did. Thank you for that.

I've actually used solenoids for this sort of thing but they are indeed servo motors.
I think you expressed the crux of my problem, I do need to break up the data into 4 or 5 stems BUT because I am so out of practice I can't figure out where to make that change and then how to bring it all back together and output.

I hope this clarifies.

Yeah if that's the case I would do it something like what I did, have a 'top level' bang/metro/whatever, then a stem for each solenoid you want to control.

Probability is a good way to handle it if you want each solenoid to trigger only sometimes but still have its own random data. You could make it more elegant by having a fade time between each position so it moves to the new position over the period of time between teach change.

Another improvement would be to time to see how long it takes the solenoid to move around, and then build that latency into the patch, so if it takes 500ms to move 360degrees, then make sure you trigger 125ms early if you want it to move from midi values 32 to 64.

Thanks.
I see what you've done. It makes sense, though I have to play around with it and see.

I will have to see if I can essentially make one motor the constant dominant movement and have the others work at fractions of the metro.

The way the fader works in the original patch controls how much the movement the motor makes.

If that's the case you should look at metro using 4n 8n arguments. I've not actually used it, so can't comment or help out, but it's designed to do exactly what you want (subdivision to a master clock pulse).

Or you can look at rate~/phasor~ if you want to step into the signal domain.

In the original patch I am able to use the fader to change the range one the rotation o the servo motors (currently assigned to #2) but I haven't figured out how to do that so that each motor has that as an individual option. So 4 channels, each with fader control so I can spot adjust the motors each time I set up.
-the robot stands in front of percussion so the arms are adjusted depending on what 4 things he's banging on.

I appreciate the help, it been so long since I've worked with MIDI in max and mathematics are very much a weak point.

Here's an example of the n arguments Rodrigo was talking about and I also threw in a way to use makenote to return the servo to zero. HTH

Thanks Rick, that's really useful and I dare say even musical.
I very well may use some of that.

I'm still a bit lost in terms of the handling of the multiple channels going into the notein in terms of whether I need to parse them in some way. But I'm slowly getting back to understanding the generation of the notes and will make some subpatches.

Tommy

Okay, as I break apart this project into segments I keep coming into new areas I've completely forgotten.
I have the beginning of a note order chooser. The premise being that one clicks get's a group of notes and that plays as a loop.
What I haven't figured out is what goes next. does it go straight into a noteout object?
