APC40 footswitch problem

Post by mersault » Thu Aug 20, 2009 4:05 am

This seems to be something simple, but maybe its not. I have a footswitch hooked up to the apc40 and I want to use it to control autofilter. The problem is, it only goes from one value directly to another - and doesn't move gradually.

I've used this same footswitch to do almost the same exact thing through my PCR-M80 keyboard and Kontakt and it worked as I would think it should - without having to do anything special.

Anybody have similar experiences? Any ideas?

help? Please?!

i don't have an apc but there are foot switches and expression pedals..you sound like you got it hooked to the switch port that puts out 0 or 127 value and you need to be in exp. pedal port witch sends 0thru127 for knob movements...

Thanks for the response Agent G. You're right. I should say Expression Pedal - that's what I mean. Reading your post makes me think that maybe the two "Foot Switch" ports on the APC40 (labeled FC1 & FC2) were not at all meant to be used as expression pedals. I hope that's not the case. I can imagine some significant uses for such pedals. I guess growing up a guitar player puts your mind in that mode.

Anybody have any idea if this is the case?

Sorry... I'm pretty sure the FS inputs on the APC are 'switches' only.

HI there, not sure if this will work or not, all depends whether you can change what is essentially a footswitch into an 'expression' switch or not, but if you sift through this thread http://forum.ableton.com/viewtopic.php? ... 7&start=15 you'll see a few of us have had polarity issues with certain pedals and the APC40 - if you try Midipipe you may be able to chnage what messages are transmitted when passing through an APC40 footswitch... I could be wrong but FWIW may be worth investigating...I don't have an expression pedal myself so can't test it!! All the best!

The APC40 has 2 footswitch inputs that detect ON/OFF states (MIDI 0/MIDI 127). They do not support expression pedals which can give you access to the range of MIDI values.
