Radias: Footswitch to switch arp on/off

klangsulfat · Post by **klangsulfat** » Thu Nov 22, 2007 8:16 am

To switch the arp on/off remotely I assigned the footswitch to the arp button. Sometimes it works as expected, sometimes I have to push the footswitch twice to change the status of the arp button. I'm not sure, but this behaviour could be patch dependent. Switch polarity setting is correct. I also tried another foot switch - same game. Any ideas how to solve this problem?

After reading you posting I checked this out with my Radias and the Korg PS-1 foot switch.
Unfortunately I got the same result as you.

Cheers

OK, here's what I figured out:

If you don't change programs, the switch works just fine. I tried both latch mode (where it toggles on and off every time you hit the switch) and unlatch (arp is on when switch is depressed).

Change programs, then things get funny. Example: in one program the arp is normally off. I turn it on with the switch (latch mode) and then change programs. When I return to the first program, the arp light was off (default for that program). The first press of the pedal did nothing, the second time I hit the pedal, the arp light came on.

So it seems that the Radias "remembers" the latched pedal state. If the arp is in the opposite state (off when the pedal is on, or vice versa) when you select a patch, you'll have to hit it twice.

Solution: whenever you select a new program, hit the pedal until you get the arp state that you want, then you are good to go.

Are these momentary switches you are using???
or are these on / off switches ???

You can program the switch mode to be unlatched (in which case a momentary switch acts normally) or latched (in which case a momentary switch acts as a toggle). Using a latched footswitch, you would want to always use unlatched mode. You can also choose polarity of the switch.

In latched mode, the Radias remembers if the switch was last on or off...this is global so is remembered across program changes.

If the latched state is on and you choose a new program where the arp is currently off, it takes two presses of the switch to turn the arp on. The first toggles from on to off, but the arp is already off. The second toggles it on.

The same thing happens if the last state was off and the new program has the arp on, the first press goes from off to on, but the arp is already on. The second press turns it off.

So the worst case is you may have to press the footswitch twice the first time you want to change the arp state after switching to a new program. After that single presses will work fine until you change programs again.

It's annoying while a live situation and smells like a bug

Anyway, thank you for clarification.

That is what I was asking.....which type of manual switches were being used....
and being momentary, if it was NormallyClosed or Normally Open........
My experiment with NC, set to the wrong polarity gives 1 pedal motion to start the Sequencer on all programs, however, the first trigger is on release of the pedale....you change the program ... step on the pedal... release it to start the sequencer....I have used the release of switch for punching in and out tracks in the studio for years..... It actually seems more accurate in timing, than pedal down to punch in....(loss of mechanical contact may be easier to detect than contact???) who knows...
That is my work around.... try it..... Yamaha and Roland use NC switches....Korg Alesis and Ensoniq use NO.....
