midifying a pedalboard

[bumblebee001]

I was thinking of midifying a pedalboard the easy way.... by buying a midi-usb keyboard (Beringer UMX) and cannibalising it and transferring the electronic bits to the pedalboard which I have set up with a reed switch for each key (pedal). However it transpires that the electronic keyboard I was going to use has 2 switches for each key. Would anyone know what each of the 2 switches would be for? One of the pair must be the one I need to connect to each reed switch. What about the other? Would anyone happen to know?

The 2 switches give some touch sensitivity - the circuitry times the operation of the switches - if you press the key softly there is a longer time between each of the switches making.

When pressing hard and fast - the time difference is smaller.......

How ingenious! So, can I use either of the pair for a virtual organ pedal keyboard where touch sensitivity is not important nor is it necessary? Would the notes play if only one switch is activated but not the other?

You are going to have to 'try it and see'........!

I guess so too! I thought there's no harm in asking though.

The sad truth turns out to be that BOTH switches need to be activated together with the first before the second (not vice-versa). Disconnecting the second will not stop the note from playing until the first is disconnected too.

That has created a problem as I cannot use the Beringer midi-usb setup unless I think of a way of redesigning the switch system I have already installed on the pedalboard. javascript:smilie('')

I wish I could find an easier, more straight forward solution like a simple 32 key midi-usb keyboard in which each note is activated by one simple switch. javascript:smilie('')
