Foot Piano

The italian dude offered to make me pay $500 to ship back to italy, and another $500 to return it back to america...
For that price, i can just outfit the pedal with quattros, and new pedal sensors...
I'm too angry with the hall effect sensors... i want to rip them out...

this arduino is proprietary software the dude wont give out the source code, which why I assume he offered to have me pay extortionate rates to ship for troubleshooting... what a nightmare

You can see here the wireing harness, attaches to some arduino with two 16 channel daughter boards..

and then the part number on hall sensors 49E 92980 (or 929BD?) i cant tell even with maginfying glass...

I really want to thow those hall sensors in the trash...
I want to replace with something of better quality...

There is nothing wrong with Hall effect technology. The problem, which is evident in the pictures you attached, is that the guy is good with wood, but not so much with electronics and coding. When your MIDI Expression comes, hook it up to one of those hall effect sensors. There are wiring diagrams in the manual. Set the pedal type to 'Expression Pedal', calibrate, and change the mode to 'note mode'. You should be able to get velocity sensitive notes from that.

thanks for the help Rob. I'll do that. I look forward to your equipments arrival...

Well, the midi expression showed up, I soldered an XLR pigtail to the hall effect sensor (the pin outs are correct) however the hall senor must not be working at all, or needs auxiliary which the ME is not providing, cause the ME is not sensing anything... So I'm probably gonna scrap the whole AGO Pedal idea, and just use an array of FC3A or somthing...

But my FC3A doesnt seem to function correctly... If I hit the pedal once, the midi stays on my FL Studio stays on... When I let off the pedal I want the sound to stop... how do I make the ME do that?

[Rob]

Can you send me a screenshot of your settings?

Just checked over here and everything seems in order. This is using the latest version of the software from the downloads page.

kindly disregard... things seem to working fine after restart FL Studio and ME...

[joshebosh]

I suppose the testing is as good as can be expected... The FC3A doesnt work as well as I'd hoped... I calibrated it, but press too softly or even medium and the note wont even send to FL Studio... and if I dont keep my foot down to 127 it will send the stop note... It'd be nice if it wouldnt send the off note until my foot lifts like half way at least... I'm hoping to get a true velocity pedal board working... but I cant seem to find anything proving a true velocity effect.... this whole pedalboard effort is turning out to be a huge disappointment so far... what do you suggest?

I've found a 32 hall sensor kit for converting old organ pedalboards to midi, but it seems no different that the hall sensor harness that came with the the AGO board, which turned out to be garbage, so i'm leary of that...

I'm tired of wasting money on this project...

But in any case, i'm thinking about starting with 3 quatros to build an octave using sustain pedals, cause the expression part of FC3A just doesnt satisfy... i'm running out of ideas... got any setting i can try to not allow ME to send off note until pedal is half way up? And how to improve the velocity sensitivity of the ME/FC3A?

I can make that change.

but press too softly or even medium and the note wont even send to FL Studio.

Yes, that's correct. But you would have to be pressing the pedal very slowly for that to happen. I can possibly make it more sensitive.

The FC=3A works extremely well for me. Can you send me a screenshot of your settings so I can have a look?

Ya heres anitmated gif of various panels... Seems the more i mess with it, it appears to work decently... i put a different plugin in and it seems to react much better for velocty than other plugin I was using... i suppose the velocity sensitivity depends on what synth is used... so just like you have a Min setting before note turns on, it would be nice to max it will need to go under before note turns off
