I've got the KD-8 plugged into FS1 on the back of the APC40 and...nothing. Live doesn't display any MIDI info coming in either. I've tested other triggers, cables, I know everything works. I know I won't get any velocity sensitivity, but I'm OK with that. Has anyone successfully plugged in a drum pad trigger to either of the inputs on the back of the APC40?
Thanks for the help!

Re: APC40 not recognizing Roland KD-8 kick pedal trigger
I think FS1 and 2 are mostly used for on/off action.. Sustain pedals etc..
Do you know what kind of signal the KD-8 sends?

Re: APC40 not recognizing Roland KD-8 kick pedal trigger
I'm not sure what kind of signal it sends out, what different kinds of midi signals are there? I have an Alesis ControlPad that gets the signal from it fine (sidenote: the ControlPad is a total POS because if you hit 2 pads at the same time it cancels one of them out) and I can route the KD-8 into Live from there, but I don't want to bring the ControlPad to a gig just to make a kick drum trigger work. Any ideas anyone? I can't be the first person to try to plug in a drum trigger to the back of the APC40...
Thanks!
Thanks!
Re: APC40 not recognizing Roland KD-8 kick pedal trigger
Im pretty shure you need an interface, like youre Alesis ControlPad or something smaller..
It doesnt work like a normal miditrigger. (80% sure)

Re: APC40 not recognizing Roland KD-8 kick pedal trigger
Interesting question. Whilst pedals aappear simple, in practice there seem to be lots of possible differences between them. I'm not an expert but this is what I think is going on:
A drum trigger normally involves a piezo transducer to convert pressure into an analog electrical signal. The amount of pressure is the velocity sensitivity. Your Alesis can take this signal and convert it into a midi signal at the appropriate velocity.
I suspect that the APC-40 is instead looking for a sustain pedal, where the pedal either opens or closes a circuit (whether latching or non latching). This is again an analog electrical signal rather than MIDI. The APC-40 would convert that change in circuit into a midi signal at a default velocity. WI would guess that when the APC-40 sees the drum trigger it is not interested in voltage changes and as the circuit is always complete the APC-40 does not notice that the trigger has been activated.
If you want to use the KD-8 you will need a device (such as the Alesis) that can read the trigger signal and convert to midi. However if you don't need velocity the cheapest solution would be to buy a sustain pedal to plug into APC-40.
