Ghost notes

Recommended Posts

I connected both the pedals and the keyboard to my midio128. After some tuning (notes not working, broken ic etc.): all notes work and I can play. But sometimes I get some random ghost notes especially when I use the pedals. Even if these ghost notes sound funny: there are difficult to stop... So I want to get rid of the ghost notes. Possible solutions I could think of:

 

1) reduce the length of the wires: hardly impossible

2) replace the reedcontacts of the pedals (22 out of 27 are very old)

3) connect a powersupply to the diomatrix of the pedals

4) reduce the resistors of 10k to 100k?????

 

combination of the solutions...

 

Next step is to connect a swell pedal(s), fader and the registers. I ordered an ainser64 pcb so as soon as it arrives I will continu.

Thanks for posting the pictures, this makes it much easier to get an impression about possible problems! :)

I think that the cable length between the first and the second MBHP_DIO_MATRIX module is too long, this could cause such effects.

It shouldn't be longer than 10 cm

 

Best Regards, Thorsten.
