It’s been a while since my last post. I am in the process of making an application to interface piezo triggers to MIOS. The triggers will be connected to a modified version of the analog side of admir’s circuit.This circuit is complete and in the testing phase,and I am now working on the code.The application will be released as a stand alone application first and then I will attempt to implement it into the MB64 code,so the triggers can replace some of the pots.If anyone has interests or ideas please let me know.
In Australia, NZ, they are available from Jaycar, you just buy a piezo transducer (buzzer) and pull it out of the plastic casing (acoustic resonator, like a guitar) and then it works ok as a trigger. around $3 aus each
I don’t think those piezo’s can send aftertouch, as they need a percussive hit, to generate a voltage spike. Unless the aftertouch was ‘fake’ i.e. added by the microcontroller after each hit.

Nope. They just need that for high voltages (so for the velocity). If you have a changing pressure, the voltage changes, too, but in a veeery small amount (and only changes linear to the *variation* of that pressure - not directly linear to the pressure itself) .
Really don’t know if you can use that or even if its worth it… was just an idea … :)
Midibox Drum Triggers working now. Still need some tweaks on the software and hardware sides but it is coming along nicely(thanks to TK’s drum trigger driver).
I wan’t to tweak it a little more before the first release.
I haven’t started the implementation for MB64 yet but, Thorsten has made his code very easy to understand. So maybe it won’t take me to long to get a working version up and running.
Will each module employ a scalable, slave-core model, like the MF module?
8 triggers per slave core?
I am very excited about this one.
Yes the trigger to analog interface(buffer circuit) will handle only 8 inputs right now. So if you used 8 slave modules you can get 64 triggers to the core in muxed mode. Using the ainx4 modules.
I haven’t tested this yet as I am only in the first phases of development.But in theory this is how it works.

Why don’t you post the schematics, so we can discuss it…
Has there been any ideas on making the triggers velocity sensitive? I was originally planning to split my output line between 1 AIN and 1 DIN (DIN for trigger, AIN for velocity level). As of now I am not shure if there will be any problems but I am hoping to try it out soon. I Hope this idea will help out.
