Yep.
There's a demo layout that uses this included in the app.
Midi Designer Pro 2 has this feature as well. https://mididesigner.com/wiki/doku.php/manual:chapter-other-advanced-control-concepts?s[]=accelerometer#accelerometer
Mozaic too.
oh you're right. oh and there's also a demo layout where he demonstrates how to make knobs that use vertical movement. you think he added that after your message?
Hm, I see the gyro/accelerometer template uses scripting though. but I think I got it figured out enough that I can copy/paste it
this app is so cool. and now I also understand the question of the other thread/the importance of touchOSC being able to run in the background :P
I can’t wait. I haven’t found that kind of behavior since Beatsurfer. I was bummed BS was never maintained. I guess there wasn’t much interest in it. The dev did move on to collaborate on another project. Plus he performed music and stuff.
[Edit] Beatsurfing
The best gyro/ movement app that I have found is made by Bit Shape. They had an app called “TC-Orbiter” which may no longer be available. TC-Data is the more robust app they still keep updated. Both apps generate MIDI from gyro and accelerometer movement.
I use it to send CC data to MIDI Designer Pro or other apps and it works fantastic. Every single axis of movement can be programmed and it is astonishingly accurate and responsive compared to other apps I have used.
[edit:] disclaimer, I have not purchased Touch OSC so I can’t compare how well it handles gyro input or how difficult it is to set up. I can say that TC-data has no coding at all, just simple straight forward menus and a useful graphical interface.
Dec 4th the new sonic logic 4 drops, there’s a thread
I tested it yesterday and it worked very well. The advantage is, since it's scripted, you can do any ratio and starting value and i guess also any math, for example an exponential response curve.
(maybe some smoothing would be a nice addition, but I don't know how to realize that.)
And for any more advanced response curves, you could take the drambo graphic wave shaper element and guide the midi output from TouchOSB (or any other app) through the wave shaper...
(maybe drambo can even do smoothing, idk)
The standard way to do this would be some kind of moving average filter. I'm not sure about the specifics of the scripting in Touch OSC, but a simple general approach would be to perform a weighted average of the current incoming value and some number of previous values. For example, y[t] = 0.5(x[t] + x[t-1]). You can then experiment with coefficients and the number of previous terms. You could also try exponential weighting where y[t] = ax[t] + (1-a)y[t-1].
would be funny if you could just input the midi signal into a low pass filter to filter out the high frequency movement
That's exactly what this is! It's a pretty crappy lowpass filter by audio standards, but for MIDI data it's perfect.
