Pedal problem


I have a new "Classic AGO MIDI Pedalboard" from Midiworks with the following problem:
-- hold down AA
-- then hold down G#G# (just below AA)
-- let go of AA
-- AA continues to sound until G#G# is released

This only happens with this one pedal as far as I can tell. Monitoring MIDI messages, I see that
releasing AA (while still holding down G#G#) is not resulting in a note-off message being sent
for AA. Also, If there is the slightest of gaps between playing the AA and then the G#G#, then
no problem.

What can I do?!

I had the same problem but 100 times worse. Every sharp note on the pedal board was stuck until a closer pedal was pressed and released, and around 40% of the notes were stuck if the release was too gentle.
After around 6 months of carelessly stomping on the pedal board because it was already ruined, it fixed itself.
Im not recommending to play with too much force to fix this, but for me it seems to have worked

RE: Pedal problem

Could the magnet on G#G# be a little too close to the switch for AA so that it holds the switch closed after you release AA? You might be able to determine if that's the cause by slipping the blade of a steel table knife between the magnet and switch. If that stops the problem, remove the back of the pedal board and move the magnet slightly if it's loose or they can usually be trimmed by slicing off a thin strip with an Xacto knife. Don't slice off too much or it won't work at all.

RE: Pedal problem

I would suggest that you contact Attila Magyar at Classic Organ Works in Canada.

They've always been very helpful with anything I asked them about.

Here is his direct email: attilam@organworks.com

I hope they can help!

Peace,

Right! Beat you to it... talked to Attila this afternoon (armed with various info from here and the
Facebook Hauptwerk forum). He confirmed the approach of adjusting a reed switch.

Unfortunately, this is proving somewhat problematic so far: when I pull out the pedalboard and
remove the back, the problem ceases! Then I put it back, and the problem resumes. This
must be some inversion of Murphy's Law!

RE: Pedal problem

Aren't the reed switches fastened to the back? I would expect that your pedals would stop working completely when the back is moved away. Can you explain what you mean by "take off the back?" Are the reed switches mounted on a different piece of the frame?

The switches are at the back, but there's a back cover that needs to be removed to get to them.

Even though I was unable to reproduce the problem with perfect consistency, I adjusted the
position of the switch for AA (moving it about 1/16 inch), put everything back together, and
the problem seems to have gone away. We'll have to see if it stays solved!

As long as the magnetic lines of the earth don't shift again, you should be ok!

There is a support video here:

which illustrates the process.

Hi Gary.

I'm glad that it looks like you got it fixed!

These things are ALWAYS a pain to have to deal with and correct. :-)

Peace,
