Weird bug? Pad A2 triggers A1 during recording only

Hi there,

MPC500 with jumbo pads + 128mb expansion; no other mods. Running 1.31.

I am working with some samples I recorded from vinyl. When I assign a sample to pads A1-A3 and attempt to record a sequence, pad A2 triggers pad A1's sample in the recorded track.

For example:
A1 - Intro loop
A2 - Kick drum
A3 - Snare drum

If I am recording using pads A2-A3 only, what comes out is a track that seems like I was using pads A1 and A3 only; essentially pad A2 triggers pad A1 during the recording.

There are two odd things about this:
1. When I play "live" with pads A1-A3, A2 triggers A2; not A1 as it does during recording. This helps me rule out the fact that there is a physical issue with the jumbo pads.
2. When I load up other programs, this doesn't happen. It only seems to be happening with my new samples that I recorded.

Looked in the forums but didn't see this particular issue. Am I missing a setting on something?

perhaps you accidentally changed the MIDI note assigned to PAD2 to the same as PAD1...

Weird, man. I tried a couple different things to try to reproduce it but couldn't. Can you try to make a new program with those three samples but put them on different pads (A1, A6, A7 for example). See if it still happens after that.

I've resolved the problem.

What I did was copy the samples to my computer via USB; erase the original samples from the card; create a program in MPC Maid and reloaded everything to the card.

Works fine now. Must have just been a weird little bug!

Thanks for the replies though.
